Showing CustomDialog as modal dialog and get result (mahapps)

I have a class which creates SimpleDialog (now CustomDialog) with custom contents. So far I'm successful in showing it & closing it. But how to return its return to parent window? Just like how ShowDialog method does? The code so far is,
internal void fnShowDialog(MainWindow parent)
{
SimpleDialog dialog = new SimpleDialog();
StackPanel panel = new StackPanel();
Label block = new Label() { Content = "custom message" };
TextBlock block1 = new TextBlock() { Text = "custom message", FontSize = 22 };
Button button = new Button() { Content = "close" };
button.Click += (s, e) =>
{
parent.HideMetroDialogAsync((BaseMetroDialog)dialog);
};
panel.Children.Add(block);
panel.Children.Add(block1);
panel.Children.Add(button);
dialog.DialogBody = panel;
parent.ShowMetroDialogAsync((BaseMetroDialog)dialog);
}
I need to know the result of this dialog for further precessing accordingly.

I suggest you get the dialog's result in the Click event handler, the same place you call HideMetroDialogAsync.

Every Form has DialogResult property. You can set them on some event and then check the enum value of them in your dialog objects after closing the Form.
BaseMetroDialog could have DialogResult property which would be visible to parent.

This is a simple asynchronous process:
You should use await keyword to get the result:
var result = await parent.ShowMetroDialogAsync((BaseMetroDialog)dialog);
Don't forget to return result; at the end of the method.
Change your method definition to return this result like this:
internal async Task<MessageDialogResult> fnShowDialog(MainWindow parent)
This is the full method:
internal async Task<MessageDialogResult> fnShowDialog(MainWindow parent)
{
SimpleDialog dialog = new SimpleDialog();
StackPanel panel = new StackPanel();
Label block = new Label() { Content = "custom message" };
TextBlock block1 = new TextBlock() { Text = "custom message", FontSize = 22 };
Button button = new Button() { Content = "close" };
button.Click += (s, e) =>
{
parent.HideMetroDialogAsync((BaseMetroDialog)dialog);
};
panel.Children.Add(block);
panel.Children.Add(block1);
panel.Children.Add(button);
dialog.DialogBody = panel;
var result = await parent.ShowMetroDialogAsync((BaseMetroDialog)dialog);
return result;
}
You can use this method with an await like this:
var result = awiat fnShowDialog(parent);
if(result == ...)
{...}

Variable not updating on closing a new pop up form after clicking button

I am trying to make a button that when clicked pops up a new form with a yes and no button and then make an if statement based on what button is pressed. Here is my current code:
private YesNoMessageBoxResized newBoxResized;
private string buttonClickResult;
public void YesNoNewMessageBox(string title, string message,string buttonYes, string buttonNo)
{
YesNoMessageBoxResized msgResized = new YesNoMessageBoxResized(title, message, buttonYes, buttonNo);
msgResized.StartPosition = FormStartPosition.CenterScreen;
msgResized.TopMost = true;
Button yesButtonResize = new Button();
Button noButtonResize = new Button();
//yes button
yesButtonResize.Text = buttonYes;
yesButtonResize.Size = new Size(150, 80);
yesButtonResize.Font = new Font("Arial", 26);
yesButtonResize.Location = new Point(100, 150);
//no button
noButtonResize.Text = buttonNo;
noButtonResize.Size = new Size(150, 80);
noButtonResize.Font = new Font("Arial", 26);
noButtonResize.Location = new Point(300, 150);
//make a copy of the current form
newBoxResized = msgResized;
//eventhandlers
yesButtonResize.Click += YesButtonResizeClicked;
noButtonResize.Click += noButtonResizeClicked;
newBoxResized.Controls.Add(yesButtonResize);
newBoxResized.Controls.Add(noButtonResize);
msgResized.Show();
}
private void YesButtonResizeClicked(object o, EventArgs sEA)
{
this.buttonClickResult = "true";
this.newBoxResized.Close();
}
private void noButtonResizeClicked(object o, EventArgs sEA)
{
this.buttonClickResult = "false";
this.newBoxResized.Close();
}
private void buttonRestoreDefaults_Click(object sender, EventArgs e)
{
YesNoNewMessageBox("Restore Defaults?", "Restore Defaults?", "Yes", "No");
if (this.buttonClickResult == "true")
this.restoreDefaults();
}
My problem is that after hitting yes and closing the form that pops up, buttonClickResult is not seen as true and therefore the restore default function I am calling is not called. Only when clicking on the "RestoreDefaults" button again is the function called. So, it seems that the onclick event for buttonRestoreDefaults_Click isn't reconizing the onclick for the yes or no buttons in the form that popups until clicking on it again. Is there a way around this or some sort of implementation to fix this? Thank you.
Also, here is the code for the class. I was thinking about using delegates and event handlers, but I am not sure if I actually need that since what I have works, but just doesn't update the variable on closing correctly:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Drawing;
using System.Windows.Forms;
using System.Runtime.InteropServices;
public class YesNoMessageBoxResized : Form
{
private Label labelMessage;
//no default button specified
public YesNoMessageBoxResized(string title, string message, string buttonYes, string buttonNo)
{
InitializeComponent();
this.Text = title;
this.labelMessage.Text = message;
this.Deactivate += MyDeactivateHandler;
}
public YesNoMessageBoxResized()
{
InitializeComponent();
}
private void InitializeComponent()
{
this.labelMessage = new System.Windows.Forms.Label();
this.SuspendLayout();
//
// labelMessage
//
this.labelMessage.AutoSize = true;
this.labelMessage.Font = new System.Drawing.Font("Microsoft Sans Serif", 18F, System.Drawing.FontStyle.Regular, System.Drawing.GraphicsUnit.Point, ((byte)(0)));
this.labelMessage.Location = new System.Drawing.Point(12, 31);
this.labelMessage.Name = "labelMessage";
this.labelMessage.Size = new System.Drawing.Size(165, 29);
this.labelMessage.TabIndex = 3;
this.labelMessage.Text = "labelMessage";
//
// YesNoMessageBoxResized
//
this.ClientSize = new System.Drawing.Size(572, 268);
this.Controls.Add(this.labelMessage);
this.Name = "YesNoMessageBoxResized";
this.ResumeLayout(false);
this.PerformLayout();
}
protected void MyDeactivateHandler(object sender, EventArgs e)
{
this.Close();
}
public delegate void buttonYes_ClickResultEvent(object o, EventArgs sEA);
public event buttonYes_ClickResultEvent choiceResult;
}
public class buttonYes_ClickResultEvent : EventArgs
{
public buttonYes_ClickResultEvent(bool choice)
{
this.buttonResult = choice;
}
public bool buttonResult;
}
**I posted this on codereview, but then they told me to post it here since it deals with solving a problem.

just for a test, try using a global variable and set that to true within your yesbuttonresizedclicked event.
something like
public static bool yestest = false;
private void YesButtonResizeClicked(object o, EventArgs sEA)
{
yestest = true;
}

I sort of fixed it by adding a function that had the if statement withing the other button events. I am open to other solutions though:
private YesNoMessageBoxResized newBoxResized;
private string buttonClickResult;
public void YesNoNewMessageBox(string title, string message,string buttonYes, string buttonNo)
{
YesNoMessageBoxResized msgResized = new YesNoMessageBoxResized(title, message, buttonYes, buttonNo);
msgResized.StartPosition = FormStartPosition.CenterScreen;
msgResized.TopMost = true;
Button yesButtonResize = new Button();
Button noButtonResize = new Button();
//yes button
yesButtonResize.Text = buttonYes;
yesButtonResize.Size = new Size(150, 80);
yesButtonResize.Font = new Font("Arial", 26);
yesButtonResize.Location = new Point(100, 150);
//no button
noButtonResize.Text = buttonNo;
noButtonResize.Size = new Size(150, 80);
noButtonResize.Font = new Font("Arial", 26);
noButtonResize.Location = new Point(300, 150);
//make a copy of the current form
newBoxResized = msgResized;
//eventhandlers
yesButtonResize.Click += YesButtonResizeClicked;
noButtonResize.Click += noButtonResizeClicked;
newBoxResized.Controls.Add(yesButtonResize);
newBoxResized.Controls.Add(noButtonResize);
newBoxResized.Show();
}
private void YesButtonResizeClicked(object o, EventArgs sEA)
{
this.buttonClickResult = "true";
this.DoIfStatement();
this.newBoxResized.Close();
}
private void noButtonResizeClicked(object o, EventArgs sEA)
{
this.buttonClickResult = "false";
this.DoIfStatement();
this.newBoxResized.Close();
}
private void DoIfStatement()
{
if (buttonClickResult == "true")
this.restoreDefaults();
}
private void buttonRestoreDefaults_Click(object sender, EventArgs e)
{
YesNoNewMessageBox("Restore Defaults?", "Restore Defaults?", "Yes", "No");
}
I think I need it to be more modular though. I don't always want the same if statement there. So, I don't always want to be a yes and no with regards to restore defaults. I may want it to do something else with another function call and have yes and no buttons do something else.

You can just use MessageBox to do this for you:
if (MessageBox.Show("Yes or no?", "", MessageBoxButtons.YesNo)
== DialogResult.Yes)

You could change the form to a modal dialog form. Make the Accept and Cancel buttons properties equal the appropriate button. Then change the dialog result of each button to the appropriate value. Now when you use the ShowDialog the form will return the appropriate DialogResult.

How to show toast after performing some functionality in windows phone 8

I want to show something like toast after some functionality performed. i-e I have a save button and I want that when it pressed then a toast should be shown with the text Record Saved etc. I read posts that show toasts are only for back-ground agents. I know someone will give me good guidance. please specify some code.
Thanks

You can use the Toast Prompt from the Coding4Fun Toolkit to perform a toast notification via code. After referencing the toolkit (ideally via NuGet) you can use it like this:
ToastPrompt toast = new ToastPrompt();
toast.Title = "Your app title";
toast.Message = "Record saved.";
toast.TextOrientation = Orientation.Horizontal;
toast.MillisecondsUntilHidden = 2000;
toast.ImageSource = new BitmapImage(new Uri("ApplicationIcon.png", UriKind.RelativeOrAbsolute));
toast.Show();

I prefer ProgressIndicator in my apps but you can use Popup or ToastPrompt.
Sample project.
// popup member
private Popup popup;
// creates popup
private Popup CreatePopup()
{
// text
TextBlock tb = new TextBlock();
tb.Foreground = (Brush)this.Resources["PhoneForegroundBrush"];
tb.FontSize = (double)this.Resources["PhoneFontSizeMedium"];
tb.Margin = new Thickness(24, 32, 24, 12);
tb.Text = "Custom toast message";
// grid wrapper
Grid grid = new Grid();
grid.Background = (Brush)this.Resources["PhoneAccentBrush"];
grid.Children.Add(tb);
grid.Width = this.ActualWidth;
// popup
Popup popup = new Popup();
popup.Child = grid;
return popup;
}
// hides popup
private void HidePopup()
{
SystemTray.BackgroundColor = (Color)this.Resources["PhoneBackgroundColor"];
this.popup.IsOpen = false;
}
// shows popup
private void ShowPopup()
{
SystemTray.BackgroundColor = (Color)this.Resources["PhoneAccentColor"];
if (this.popup == null)
{
this.popup = this.CreatePopup();
}
this.popup.IsOpen = true;
}
// shows and hides popup with a delay
private async void ButtonClick(object sender, RoutedEventArgs e)
{
this.ShowPopup();
await Task.Delay(2000);
this.HidePopup();
}

using Windows.UI.Notifications;
var toastXmlContent = ToastNotificationManager.GetTemplateContent(ToastTemplateType.ToastText02);
var txtNodes = toastXmlContent.GetElementsByTagName("text");
txtNodes[0].AppendChild(toastXmlContent.CreateTextNode("First Line"));
txtNodes[1].AppendChild(toastXmlContent.CreateTextNode("Second Line" ));
var toast = new ToastNotification(toastXmlContent);
var toastNotifier = ToastNotificationManager.CreateToastNotifier();
toastNotifier.Show(toast);

Show a link to a path in a message form in c#

I have a desktop application in C# .In this I have a form in which I show different messages .
I have one message who say : "The output file was generated in : C:\Work\result.txt".
How can I show this path to the file as a link and when the form with this message is shown to see the path as a link and when the user click the link to open the specified path/file?
I tried :
The output file was generated in : C:\Work\result.txt
But doesn't work.
Thanks !

You can have an event for on-onclick, and then you can open file using the below code.
System.Diagnostics.Process.Start(#"C:\Work\result.txt"); //or like
System.Diagnostics.Process.Start(#"C:\Work\result.docx");
Here, the default program must be there for the file. Then only shell will run associated program reading it from the registry, like usual double click does in explorer.

MessageBox.Show() method takes the caption, text, icon, buttons and default button of the dialog.However there's nothing mentioned in the .NET Framework documentation that says anything about adding links to a MessageBox
However, you can do the effect you want by creating a new class inherited from System.Windows.Forms.Form and add a button (or more if you like), an icon, a label and a LinkButton. Then use the ShowDialog() Method of the Form class to display the message box in modal form. You may also create a class called MyErrorBox (static class in C# 2 or just sealed in C# 1) that contains only one static method called Show() which creates a form, adds the needed controls and displays the form in modal mode. A demonstration of the last method is shown below. Then you can use this class whenever you want and wherever you please!
using System;
using System.Windows.Forms;
using System.Drawing;
namespace MessageBoxes{
public sealed class MyErrorBox{
private MyErrorBox(){}
private static Form frm;
private static string detailsStore;
private static TextBox txt;
public static DialogResult Show(string caption, string text, string details, Icon icon){
frm = new Form(); frm.Size = new Size(510, 195);
frm.Text = caption; frm.ShowInTaskbar = false; frm.ControlBox = false;
frm.FormBorderStyle = FormBorderStyle.FixedDialog;
PictureBox icon1 = new PictureBox(); icon1.Location = new Point(8,16);
icon1.Size = new Size(icon.Width, icon.Height);
icon1.Image = icon.ToBitmap();
frm.Controls.Add(icon1);
Label lbl = new Label(); lbl.Text = text; lbl.Location = new Point(88,8);
lbl.Size = new Size(400,88); frm.Controls.Add(lbl);
LinkLabel btn1 = new LinkLabel(); btn1.Text = "View Details";
btn1.Size = new Size(72,23); btn1.Location = new Point(416,96);
btn1.Click += new EventHandler(btn1_Click); frm.Controls.Add(btn1);
//Ofcourse you can add more buttons than just the ok with more DialogResults
Button btn2 = new Button(); btn2.Text = "&Ok";
btn2.Size = new Size(72,23); btn2.Location = new Point(224,130);
btn2.Anchor = AnchorStyles.Bottom; frm.Controls.Add(btn2);
frm.AcceptButton = btn2; btn2.Click += new EventHandler(btn2_Click);
btn2.DialogResult = DialogResult.OK; detailsStore = details;
return frm.ShowDialog();
}
private static void btn1_Click(object sender, EventArgs e) {
frm.Size = new Size(510,320);
txt = new TextBox(); txt.Multiline = true;
txt.ScrollBars = ScrollBars.Both; txt.Text = detailsStore;
txt.Size = new Size(488,128); txt.Location = new Point(8,120);
txt.ReadOnly = true; frm.Controls.Add(txt);
LinkLabel lnk = (LinkLabel)(sender); lnk.Text = "Hide Details";
lnk.Click -= new EventHandler(btn1_Click);
lnk.Click += new EventHandler(btn1_ReClick);
}
private static void btn2_Click(object sender, EventArgs e) {
frm.Close();
}
private static void btn1_ReClick(object sender, EventArgs e) {
frm.Controls.Remove(txt); frm.Size = new Size(510, 195);
LinkLabel lnk = (LinkLabel)(sender); lnk.Text = "View Details";
lnk.Click -= new EventHandler(btn1_ReClick);
lnk.Click += new EventHandler(btn1_Click);
}
}
}

There's no standard MessageBox functionality that'll be able to do this via link label. What I suggest is you use the Yes/No Messagebox buttons and from the option selected you then apply an event
Something like this:
if (MessageBox.Show(
"The file is saved at the following link: link here", "Success", MessageBoxButtons.YesNo, MessageBoxIcon.Asterisk
) == DialogResult.Yes)
{
System.Diagnostics.Process.Start(#"C:\TestLocation\SavedFiles");
}

input box in asp.net c#

I need to create a simple input box on my website in C#.
It should pop up, when i call it in the code like that
String input = InputBox("Name the file");
and then I need the use string the users enters later in the code
In a .net application, it is pretty easy to accomplish, but how can i make it work in a web application? I think it should be possible with ajax, but it seems pretty complicated for such a (seemingly) trivial thing.
Is there any kind of library or framework, that I can use for this right away?
thanks in advance

It sounds to me like the behavior you are looking for is to get a popup window with a text box for the user to enter a value and click ok. Is that right?
You're right in saying that it is more complicated with a web app. In a windows app, whenever you run the C# code, whatever happens, happens at that moment. It's pretty straightforward. However, in a web app, all of the C# runs before the page is even rendered in the browser. Therefore, C# in web forms can't really pop up a window.
In order to get a popup, you'll need to do that with JavaScript. The textbox inside the popup should be an <asp:Textbox> control. You can use the Ajax Control Toolkit if youre most comfortable with .NET controls. If youre comforatble with jQuery, you should check out jQuery UI.

I'm assuming you use webforms.
The most simple thing is to make a webform with one input box (<asp:textbox runat="server" id="inputfield" />). Add a button with an onclick event (<asp:button runat="server" id="button" onclick="OnClick" />. In the onclick eventhandler you do something with the value.
protected void OnClick(object sender, EventArgs args){
string input = inputfield.Text;
// do something
}

It should pop up, when i call it in the code like that
And when exactly is this? Keep in mind that there's a fundamental difference between the disconnected nature of web development vs. application development. All of your server-side C# code has already finished executing before the web page renders in the browser. So when are you going to call this code? Also, how are you going to pass the data back to the server? A form post? An AJAX call?
If you want it to "pop up" and to post back with AJAX, I recommend the jQuery UI Dialog as the actual pop-up. Then on its close event you can make the AJAX call to the server to post the data.

If you are looking for a simple solution for a POPUP that will get user input, I recomend checking out JQuery's dialog widget. In particular the modal form, here is a link to some more information: http://jqueryui.com/demos/dialog/#modal-form

ASP.NET has a TextBox control that does just this. All items with runat="server" are accessible through server-side code.
