I need to show a MessageBox with the Show Details option , like what we get during normal windows exceptions. When the user clicks the show details option, it has to expand and show the collection of details to the user. How to achieve it in Windows forms?
Thanks in advance
These dialogs are not exposed as part of any API and so you need to create your own dialog that behaves the same way.
A dialog is simply a standard form shown using the ShowDialog method:
DetailsMessageBox dialog = new DetailsMessageBox();
if (dialog.ShowDialog() == DialogResult.OK)
{
// Handle me
}
Before your dialog closes you should set the DialogResult property of the form is set to the desired dialog outcome - you can get buttons to automatically set the dialoig result (and close the dialog) for you when they are clicked by setting the DialogResult property of the button to the desired result.
You should also set the AcceptButton and CancelButton properties of your dialog to suitable buttons so that the dialog is closed when the use presses Escape or Enter.
These types of forms are only via API available on Windows Vista and higher. You'd best just create your own form. That way you can make it precisely how you want it :)
The simplest way would be to make your own messagebox. You can then add as much additional functionality as you'd like, including event/error logging etc.
You can try the TaskDialog API, see http://msdn.microsoft.com/en-us/library/windows/desktop/bb787471(v=vs.85).aspx

I have a populated ListView dialog. If a user clicks on an option in the ListView, a new dialog is shown above the ListView.
My problems is that when I click off of the new top-most dialog (onto the ListView behind it), the new dialog's borders flash/blink several times. The icon on the taskbar also flashes. I wish to disable the flashing, but cannot find a property to change.
To show my dialog, I use the following code:
if (detail == null)
detail = new Details(opt, val, user, desc, m_l);
else
detail = null;
detail.ShowDialog();
This is intended behavior, it's because the new dialog is modal. It's drawing attention to the fact that something needs to be done.
If you need to make a non-modal form, instead of using ShowDialog(), simply use Show().
Sounds like to me you are creating modal windows each time. And you cannot resume the previous dialogs until you dismiss your new top-most window.
Take a look at this wikipedia article for information about modal dialogs.
I would advise you look at how you are creating/showing your windows.
In WPF you show windows via Show() or ShowDialog(), however, I do not know which type of ListView you are using
EDIT:
Per your comment, you want modal dialogs. The only ways I can think of even trying to remove the flashing is going into WINAPI. This doesn't seem like a job for .NET.
I want to suggest a few things:
Take a look at options for showing each window. See this MSDN page
Take a look at the options for styling each window. See this MSDN page
Reconsider your design. I know this may take a lot of work, but having so many layers of windows is kind of unappealing to most users. Ultimately, I believe this option will make your application the best.
Thank you all for your answers and guidance. I have found the best way to handle my problem.
I was using an event ItemActivated. This event was called when an a highlighted item on the ListView was clicked. This became a problem when the user would double click on an already selected item. This would cause the new dialog to show, but also flash several times.
By using the DoubleClick event instead, a single click on a selected object does nothing. A double click on either a selected or non-selected item opens the dialog without the flashes. The flashes still appear if you try to click off of the dialog box, but are not as much of an issue.
I have a messageBox with yes/no buttons.
I want the it's string text be right to left, but the buttons location be at left. and I want to change the buttons text also...
I used the below code:
MessageBox.Show("abc", MessageBoxButtons.YesNo, MessageBoxIcon.None,
MessageBoxDefaultButton.Button1, MessageBoxOptions.RightAlign);
but in this code, the buttons be on the left too. how can I set my personal change in it?
You can not edit this dialog; design your own MessageBox and customize it. For some limited options in this dialog see RightAlign or RtlReading options in MessageBoxOptions Enumeration.
example:
string message = "سلام";
string caption = "سلام";
MessageBoxButtons buttons = MessageBoxButtons.YesNo;
DialogResult result = MessageBox.Show(this, message, caption, buttons,
MessageBoxIcon.Question, MessageBoxDefaultButton.Button1,
MessageBoxOptions.RightAlign);
As far as I Know you cannot change/edit the default MessageBox of winforms. However you can create a custom message box. Look at the
Custom Message Box which might be helpful.
You can also have a look at the previously asked question over here
It is very hard to customize MessageBox outside the already provided options. RtlReading option is not meant to be used for cosmetic aligning, but to enable right-to-left scripts (such as Arabic) in left-to-right environment. What you really need is some custom message box. CodeProject has several, so maybe some of them may be useful to you. There are surely more out there on the 'net. When I go to http://www.codeproject.com/KB/dialog/ add filter for .NET and add search for messagebox this is what I get:
FlexibleMessageBox – A flexible replacement for the .NET MessageBox
A versatile MessageBox replacement
Custom Featured MessageBox
MessageBoxManager - A Windows Forms component that provides enhanced MessageBox functionality
One article even describes how to extend system's existing message box, but I don't recommend that approach.
Any idea how to display textBox control in MessageBox.
I'm working on winforms projcet c#.
Thank you in advance.
You can't. MessageBox is a special container designed to only show a message and buttons. Instead, you can create your own Form with whatever controls you want, and use .ShowDialog() on it.
You can simply add an Input box from VB.NET into your C# project.
First add Microsoft.VisualBasic to your project References, then use the following code:
string UserAnswer = Microsoft.VisualBasic.Interaction.InputBox("Your Message ", "Title", "Default Response");
And that should work properly.
It will be better to add a new Form in you application which you can customize the way you want.
and just call it from where ever required.
you could create a classic win form that looks like a message box and opening it as a modal form
perhaps using Form.ShowDialog
more info at
http://msdn.microsoft.com/en-us/library/c7ykbedk.aspx
You cannot customise the MessageBox, its better you use a popup designed using Windows Form separately and use its instance to invoke.
customPopup popup = new customPopup();
popup.ShowDialog();
Place your controls on the popup form and set their access modifiers to public if you want to access the textboxes or labels etc in your previous form.
customPopup popup = new customPopup();
popup.msgLabel.Text= "Your message";
popup.ShowDialog();
As I know there is no way to do that.
You can create a winform change it's style to look like a MessageBox and add your own controls.
Yes, as krillgar mentioned,you should create your own form. And
1. Encapsulate the form in a static class or function, so you may just call MyMessageBox.Show().
2. The textbox should have readonly=true, so the end users won't be able to change the text displayed, while they could select text and copy to clipboard.
Regarding to item 2, I believe many Windows build applications and MS Office use such approach.
using Microsoft.VisualBasic;//add reference
var Password = Interaction.InputBox("Message", "Title" ,"information in textbox", -1,-1);
In the variable "password" it receives the information that is entered from the text box.
Remember to add the reference "Microsoft.VisualBasic" in the solution explorer
Solution in here, you can create windows form and design it, set form is dialog, when you call form, it is auto show. In form you design, you set value some parameter static where other class in project, but you should set when you close form design that, OK, come back form init call show dialog, you create interval call when have == null return call, when != null you stop call back and using parameter in class static it !
I'm calling my custom dialog window with this code:
GUI.SLDialog sd = new GUI.SLDialog();
if (sd.ShowDialog() == false)
{
return;
}
But sd.ShowDialog() always returns nothing (i think), because the function breaks, but the waypoint at return; isn't reached.
Dialog is automaticly closing when I add to button:
this.DialogResult = false;//or true
Anybody know what am I doing wrong?
Thanks in advance for your help.C.H.
#edit
This is my SLDialog:
xaml: http://wklej.org/hash/9fb67fb0c7c/
cs: http://wklej.org/hash/16e3ccc6c0d/
I don't think I can tell you much here unless you post the code for the dialog but I do have a suggestion in the mean time.
Since you're already unhappy with the standard dialog boxes and customization is clearly an option why not move towards what people are coming to expect? Instead of your standard dialog why not just create a user control that lays over the rest of your UI and blurs everything out from the background? Much like a jquery dialog box you might see on a web page.
Modality is easier to control since it's just a matter of covering your entire app window with a translucent rectangle and then make the dialog window appear however you want.
Just a suggestion.
Quick question: I have a very busy form going on that I have developed for information about say book records.
I want to design an 'add new book form' that is essentially a pop up to input the info. What is the best way to do this? Use a Usercontrol that is called on a button click or menu click? an entire new form?
Have seen this type of functionality, but never designed it in a pop up have just had user input info on the actual form - and it can get very busy.
Thanks for any help. Cheers!
I'd follow a common UI idiom. Which is, from a menu choose "new". This would popup a modal dialog to accept information about the new book form. I'd use the "Popup" control for this dialog. Within this Popup control, I'd embed the actual input dialog which is implemented as a user control.
The popup control is part of the .Net framework. If you can't see the control in the VS2008 designer, then you can still use it by typing the Popup element directly in the text view of the .xaml file.
