I am design a custom message box. This message box will show a list of string. But it's not work. Can you hep me to fix it.
You can see in the picture, I have a list with 7 items. When i click the "Grade Project", the Message box don't show any item.
And this is the result I need
//Main form
private void btnGrade_Click(object sender, EventArgs e)
{
List<string> result = new List<string>();
result.Add("True");
result.Add("False");
result.Add("True");
result.Add("False");
result.Add("True");
result.Add("False");
result.Add("False");
MsgBox.Show(result,"Project 1",MsgBox.Buttons.OK);
}
This is code in msgbox form
//MsgBox form
public partial class MsgBox : Form
{
private static MsgBox _msgBox;
// Header, Footer
private Panel _plHeader = new Panel();
private Label _lblTitle;
private Panel _plFooter = new Panel();
private Panel _plIcon = new Panel();
// Panel
private FlowLayoutPanel _flpButtons = new FlowLayoutPanel();
// button
private List<Button> _buttonCollection = new List<Button>();
// Kết quả
private static DialogResult _buttonResult;
// Message
private List<String> _lblMessage;
private MsgBox()
{
this.FormBorderStyle = System.Windows.Forms.FormBorderStyle.None;
this.BackColor = Color.FromArgb(45, 45, 48);
this.StartPosition = FormStartPosition.CenterScreen;
this.Padding = new System.Windows.Forms.Padding(3);
this.Width = 800;
// Header
_lblTitle = new Label();
_lblTitle.ForeColor = Color.White;
_lblTitle.Font = new System.Drawing.Font("Segoe UI", 18);
_lblTitle.Dock = DockStyle.Top;
_lblTitle.Height = 60;
// Message
_lblMessage = new List<string>();
for (int i = 0; i < _lblMessage.Count; i++)
{
TextBox txt = new TextBox(); //Create Textbox có name txt
txt.Text = _lblMessage[i];
txt.ForeColor = Color.Red;
txt.Font = new System.Drawing.Font("Segoe UI", 30);
this.Controls.Add(txt); //add control txt
}
_flpButtons.FlowDirection = FlowDirection.RightToLeft;
_flpButtons.Dock = DockStyle.Fill;
_plHeader.Dock = DockStyle.Fill;
_plHeader.Padding = new Padding(20);
// _plHeader.Controls.Add(_lblMessage);
_plHeader.Controls.Add(_lblTitle);
_plFooter.Dock = DockStyle.Bottom;
_plFooter.Padding = new Padding(20);
_plFooter.BackColor = Color.FromArgb(37, 37, 38);
_plFooter.Height = 80;
_plFooter.Controls.Add(_flpButtons);
// Add controls vào form
this.Controls.Add(_plHeader);
//this.Controls.Add(_plIcon);
this.Controls.Add(_plFooter);
}
public static DialogResult Show(List<String> message, string title, Buttons buttons)
{
_msgBox = new MsgBox();
_msgBox._lblMessage = message;
_msgBox._lblTitle.Text = title;
_msgBox._plIcon.Hide();
MsgBox.InitButtons(buttons);
_msgBox.ShowDialog();
return _buttonResult;
}
Thank you for your watching.
Something wrong with your codes:
private MsgBox()
{
...
// Message
_lblMessage = new List<string>();
...
}
Your _lblMessage will always be an empty list so you see no message at all.
You can change your codes like this:
private MsgBox(List<String> messages)
{
...
// Message
_lblMessage = messages;
...
}
public static DialogResult Show(List<String> message, string title)
{
_msgBox = new MsgBox(message);
//_msgBox._lblMessage = message;
....
}
And also, you'd better set TextBox position otherwise all the TextBox will overlap with each other.
I've run into a bit of a wall and I don't know how I've managed to stuff it up. I'm trying to have multiple panels on my application in C# and each slides in and out from the menu along the side. I've written a separate slide class:
class Slide
{
Panel pane;
Button btn;
bool hidden;
Timer t;
const int maxWidth = 315;
public Slide(Panel p, Button b)
{
this.pane = p;
this.btn = b;
hidden = true;
btn.Click += new EventHandler(btnClick);
t = new Timer();
t.Interval = 15;
t.Tick += new EventHandler(timeTick);
}
private void timeTick(object sender, EventArgs e)
{
if(hidden)
{
SlidingPane(+10);
}
else
{
SlidingPane(-10);
}
}
private void btnClick(object sender, EventArgs e)
{
t.Start();
}
private void SlidingPane(int i)
{
pane.Width += i;
if(pane.Width >= maxWidth || pane.Width <= 0)
{
t.Stop();
hidden = !hidden;
}
}
}
And I've initialised the panels as follows:
Slide menuP, calendarP, peopleP, taskP, settingsP;
public Form1()
{
InitializeComponent();
ButtonColours();
InitialisePanes();
}
private void InitialisePanes()
{
menuP = new Slide(menuPane, menuButton);
calendarP = new Slide(calendarPane, calendarButton);
peopleP = new Slide(peoplePane, peopleButton);
taskP = new Slide(taskPane, toDoButton);
settingsP = new Slide(settingsPane, settingsButton);
}
And here's the Form designer code for the working panel:
this.menuPane.BackColor = System.Drawing.Color.SlateGray;
this.menuPane.Controls.Add(this.peoplePane);
this.menuPane.Dock = System.Windows.Forms.DockStyle.Left;
this.menuPane.Location = new System.Drawing.Point(67, 0);
this.menuPane.Name = "menuPane";
this.menuPane.Size = new System.Drawing.Size(0, 652);
this.menuPane.TabIndex = 2;
And the others are exactly the same. Eg:
this.peoplePane.BackColor = System.Drawing.Color.SlateGray;
this.peoplePane.Controls.Add(this.calendarPane);
this.peoplePane.Dock = System.Windows.Forms.DockStyle.Left;
this.peoplePane.Location = new System.Drawing.Point(67, 0);
this.peoplePane.Name = "peoplePane";
this.peoplePane.Size = new System.Drawing.Size(0, 652);
this.peoplePane.TabIndex = 2;
I've started up my application and I click on the menuButton, it works. Slides in and out beautifully. I click on the others and....nothing happens.
Can anyone see why this is happening? Everything I'm looking at tells me that it should be working.
To make sure all panes are correctly aligned with each other and (not) nested you could use code like this:
foreach( Control ctl in new[] { peoplePane, calendarPane, taskPane, settingsPane })
{
ctl.Parent = menuPane.Parent;
ctl.Location = menuPane.Location;
}
It assumes that menuPane is at the right spot and makes all others sit right on top without nesting them.
The code you posted contained incorrect nesting and moving panels to the same spot with the mouse will also create (in this case unwanted) nesting. Moving with the keyboard avoids it but is tedious.
I'm going to preface this by saying I'm sure the question has already been asked but I've tried all the suggestions and nothing seems to work for me. It just keeps returning a blank message box. If the answer were just a nice snippet of code I can add to my answer that would be fantastic.
private string Text1;
public void Button_Click(object sender, RoutedEventArgs e)
{
TextBox txtbx = new TextBox();
txtbx.Height = 50;
txtbx.Width = 200;
txtbx.Margin = new Thickness(771, 282, 0, 0);
txtbx.Background = new SolidColorBrush(Colors.White);
txtbx.Foreground = new SolidColorBrush(Colors.Black);
Text1 = txtbx.Text;
if (EditChecked == true)
{
LayoutRoot.Children.Add(txtbx);
Button Save = new Button();
Save.Height = 25;
Save.Width = 50;
Save.Content = "Save";
Save.Margin = new Thickness(771, 382, 0, 0);
LayoutRoot.Children.Add(Save);
txtbx.Text = Text1;
Save.Click += delegate
{
txtbx.Visibility = Visibility.Collapsed;
Save.Visibility = Visibility.Collapsed;
};
}
else if (ViewChecked == true)
{
MessageBox.Show(Text1);
}
}
Edit: Thanks to mjwills I moved the "Text1 = txtbx.Text;" line so this is what ended up working fyi:
private string Text1;
public void Button_Click(object sender, RoutedEventArgs e)
{
TextBox txtbx = new TextBox();
txtbx.Height = 50;
txtbx.Width = 200;
txtbx.Margin = new Thickness(771, 282, 0, 0);
txtbx.Background = new SolidColorBrush(Colors.White);
txtbx.Foreground = new SolidColorBrush(Colors.Black);
if (EditChecked == true)
{
LayoutRoot.Children.Add(txtbx);
Button Save = new Button();
Save.Height = 25;
Save.Width = 50;
Save.Content = "Save";
Save.Margin = new Thickness(771, 382, 0, 0);
LayoutRoot.Children.Add(Save);
txtbx.Text = Text1;
Save.Click += delegate
{
txtbx.Visibility = Visibility.Collapsed;
Save.Visibility = Visibility.Collapsed;
Text1 = txtbx.Text;
};
}
You declare:
private string Text1;
However you only assign it on the chance:
EditChecked = True
And you only display the message if
EditChecked = False
So, you need to assign Text1 on if the EditChecked = False. Perhaps on the declaration:
private string Text1 = "My default message";
I made a small WPF application to slide UserControls in and out, the problem I have is when a UserControl animated to slide in, then I click the button to slide another UserControl in, they both slide out - I'm not sure why this is?
public UserControl1()
{
InitializeComponent();
}
public void SlideIn(UserControl uc)
{
ThicknessAnimation tAnimation = new ThicknessAnimation();
tAnimation.Duration = new Duration(TimeSpan.FromSeconds(0.5));
tAnimation.From = new Thickness(500, 0, -500, 0);
tAnimation.To = new Thickness(0);
tAnimation.DecelerationRatio = 0.9;
Storyboard.SetTargetName(tAnimation, uc.Name);
Storyboard.SetTargetProperty(tAnimation, new PropertyPath(MarginProperty));
Storyboard storyboard = new Storyboard();
storyboard.Children.Add(tAnimation);
storyboard.Begin(uc);
this.Content = uc;
}
public void SlideOut(UserControl uc)
{
ThicknessAnimation tAnimation = new ThicknessAnimation();
tAnimation.Duration = new Duration(TimeSpan.FromSeconds(0.5));
tAnimation.To = new Thickness(-500, 0, 500, 0);
tAnimation.DecelerationRatio = 0.9;
Storyboard.SetTargetName(tAnimation, uc.Name);
Storyboard.SetTargetProperty(tAnimation, new PropertyPath(MarginProperty));
Storyboard storyboard = new Storyboard();
storyboard.Children.Add(tAnimation);
storyboard.Begin(this);
}
private void button1_Click(object sender, RoutedEventArgs e)
{
SlideOut(userControl1);
UserControl2 uc2 = new UserControl2();
SlideIn(uc2);
}
Do you set the Name property of the UserControl somewhere? Or to be more precise, do you give the second UserControl a different Name than the first one? Your animations get their target set by
Storyboard.SetTargetName(tAnimation, uc.Name);
so names should be different. Alternatively you may call
Storyboard.SetTarget(tAnimation, uc);
to specify the target.
I'm trying to display a tooltip when mouse hovers over a disabled control. Since a disabled control does not handle any events, I have to do that in the parent form. I chose to do this by handling the MouseMove event in the parent form. Here's the code that does the job:
void Form1_MouseMove(object sender, MouseEventArgs e)
{
m_toolTips.SetToolTip(this, "testing tooltip on " + DateTime.Now.ToString());
string tipText = this.m_toolTips.GetToolTip(this);
if ((tipText != null) && (tipText.Length > 0))
{
Point clientLoc = this.PointToClient(Cursor.Position);
Control child = this.GetChildAtPoint(clientLoc);
if (child != null && child.Enabled == false)
{
m_toolTips.ToolTipTitle = "MouseHover On Disabled Control";
m_toolTips.Show(tipText, this, 10000);
}
else
{
m_toolTips.ToolTipTitle = "MouseHover Triggerd";
m_toolTips.Show(tipText, this, 3000);
}
}
}
The code does handles the tooltip display for the disabled control. The problem is that when mouse hovers over a disabled control, the tooltip keeps closing and redisplay again. From the display time I added in the tooltip, when mouse is above the parent form, the MouseMove event gets called roughly every 3 seconds, so the tooltip gets updated every 3 seconds. But when mouse is over a disabled control, the tooltip refreshes every 1 second. Also, when tooltip refreshes above form, only the text gets updated with a brief flash. But when tooltip refreshes above a disabled control, the tooltip windows closes as if mouse is moving into a enabled control and the tooltip is supposed to be closed. but then the tooltip reappears right away.
Can someone tell me why is this? Thanks.
you can show the tooltip only once when mouse hits the disbled control and then hide it when mouse leaves it. Pls, take a look at the code below, it should be showing a tooltip message for all the disabled controls on the form
private ToolTip _toolTip = new ToolTip();
private Control _currentToolTipControl = null;
public Form1()
{
InitializeComponent();
_toolTip.SetToolTip(this.button1, "My button1");
_toolTip.SetToolTip(this.button2, "My button2");
_toolTip.SetToolTip(this.textBox1, "My text box");
}
private void Form1_MouseMove(object sender, MouseEventArgs e)
{
Control control = GetChildAtPoint(e.Location);
if (control != null)
{
if (!control.Enabled && _currentToolTipControl == null)
{
string toolTipString = _toolTip.GetToolTip(control);
// trigger the tooltip with no delay and some basic positioning just to give you an idea
_toolTip.Show(toolTipString, control, control.Width/2, control.Height/2);
_currentToolTipControl = control;
}
}
else
{
if (_currentToolTipControl != null) _toolTip.Hide(_currentToolTipControl);
_currentToolTipControl = null;
}
}
hope this helps, regards
The answer turned out to be a bit simpler, but needed to be applied at all times.
void OrderSummaryDetails_MouseMove(object sender, MouseEventArgs e)
{
Control control = GetChildAtPoint(e.Location);
if (control != null)
{
string toolTipString = mFormTips.GetToolTip(control);
this.mFormTips.ShowAlways = true;
// trigger the tooltip with no delay and some basic positioning just to give you an idea
mFormTips.Show(toolTipString, control, control.Width / 2, control.Height / 2);
}
}
In case of TextBox control, making it as readonly solved the issue.
I tried many but ended up using this simple trick which I think it is more effective.
Create a subclass(CustomControl with just base control in it) which extends UserControl
then instead of setting "Enabled" property to false create a Method which disables just basecontrol in it instead of whole CustomControl.
Set the tool tip on CustomControl still will be able to fire eventhandlers setting the basecontrol disabled. This works wherever CustomControl is in use rather than coding on every form you use with.
Here is the hint.. :)
public partial class MyTextBox : UserControl
{
...
...
...
public void DisableMyTextBox()
{
this.txt.Enabled = false; //txt is the name of Winform-Textbox from my designer
this.Enabled = true;
}
public void EnableMyTextBox()
{
this.txt.Enabled = true;
this.Enabled = true;
}
//set the tooltip from properties tab in designer or wherever
}
Since no one ever pointed this out, this works for any control that exposes ToolTipService:
ToolTipService.ShowOnDisabled="True"
As in this example:
<Button Content="OK"
ToolTipService.ShowOnDisabled="True" />
/*
Inspired by the suggestions above in this post, i wrapped it up as an extended ToolTip control specially works for disabled control.
// Reference example
var td = new ToolTipOnDisabledControl();
this.checkEdit3.Enabled = false;
td.SetTooltip(this.checkEdit3, "tooltip for disabled 3333333333333");

Here is how I solved this problem
I have an application that generates code automatically for a PIC32MX.
The application has 3 Tab Pages text = PWM, ADC and UART.
On each Tab Page I have one Check Box text = RPA0
The intention is, when a peripheral uses RPA0, the other peripheral is prevented
from using that pin, by disabling it on the other pages, and a tooltip text must pop up
on the disabled check boxs saying (example "Used by PWM")
what peripheral is using that pin.
The problem is that the tooltip text won't pop up on a disabled check box.
To solve the problem, I just removed the text of the check boxes and inserted labels with the text the check box should have.
When a check box is checked, the other check boxes are disabled and the label next to it takes a tool tip text.
As the label is enabled, the tooltip text pops up, even on a disabled check box.
Double the work, half the complexity.

I created a new UserControl which only contains a button.
public partial class TooltipButton : UserControl
{
public TooltipButton()
{
InitializeComponent();
}
public new bool Enabled
{
get { return button.Enabled; }
set { button.Enabled = value; }
}
[Category("Appearance")]
[Description("The text displayed by the button.")]
[EditorBrowsable(EditorBrowsableState.Always)]
[Browsable(true)]
[DesignerSerializationVisibility(DesignerSerializationVisibility.Visible)]
[Bindable(true)]
public override string Text
{
get { return button.Text; }
set { button.Text = value; }
}
[Category("Action")]
[Description("Occurs when the button is clicked.")]
[DesignerSerializationVisibility(DesignerSerializationVisibility.Visible)]
public new event EventHandler Click;
private void button_Click(object sender, EventArgs e)
{
// Bubble event up to parent
Click?.Invoke(this, e);
}
}
I found Serge_Yubenko's code worked on disabled buttons , but in order to stop the flashing make sure the tooltip pops up away from the button - just don't position it half way down the control but do this:
mFormTips.Show(toolTipString, control, control.Width / 2, control.Height);
instead of
mFormTips.Show(toolTipString, control, control.Width / 2, control.Height / 2);
This seems to follow the usual tooltip placement too...
So, I came across this post in my efforts to do the same thing, being the top result on Google. I had already considered the mouse move event and while the answers here did help, they didn't provide me with exactly what I wanted - that being a perfect recreation of the original show tooltip event.
The problem I discovered was this: For whatever reason in the API, ToolTip.Show turns the Mouse Move Event into effectively a Mouse Hover Event. Which is why the tooltip keeps flashing.
The workaround as suggested was to keep the tooltip on always show, or to display the tooltip away from the control, but that wouldn't be a faithful recreation, from the show to the timed fade. The answer would suggest that a block to prevent further execution of the code is needed - the reality was 2 blocks in the event code (One of which has no earthly reason existing and yet without it a timed event fires twice ***), a double delclaration of the control location, one inside the event, one class wide, and another class wide to check if the mouse is over a control, a class wide timer, and a Mouse Leave event to clean up due to too fast mouse movement away from the panel housing the control.
As you will see there are two events on the timer, both functions for them are in the event code as they need to reference variables get/set in the code. They can be moved out, but would then need class wide declarations on the variables, and they cause no harm where they are. FYI: "ToolTips" in the code is referencing the ToolTip control I have on the form.
*** Just to expand. If you look at the code you'll see that IsTipReset could be replaced with IsShown - after all they end up at the same value as each other. The reason for IsTipRest is this: If IsShown is used then while moving the mouse inside the control while the tootip is showing will cause a slight hiccup when the tooltip fades and very very very briefly another tooltip will popup. Using IsTipReset stops that. I have no idea why and maybe someone will spot it because I sure can't! Lol.
This is my first post here, and I realise it is an old thread, but I just wanted to share the fruits of my labour. As I said, my goal was a faithful recreation of tooltip and I think I achieved it. Enjoy!
