How do I create a message box with Yes, No choices and a DialogResult?
This should do it:
DialogResult dialogResult = MessageBox.Show("Sure", "Some Title", MessageBoxButtons.YesNo);
if(dialogResult == DialogResult.Yes)
{
//do something
}
else if (dialogResult == DialogResult.No)
{
//do something else
}
Message box with “Yes”, “No” choices in C#?
If it's in main form close method you can use it like this:
private void Form1_FormClosing(object sender, FormClosingEventArgs e)
{
if (MessageBox.Show("Really close?", "Exit", MessageBoxButtons.YesNo) ==
System.Windows.Forms.DialogResult.No)
e.Cancel = true;
}
If user press "Yes" your form will be closed due to no close cancellation.
If it is not main form close doesn't mean application exit. In this case you can close parent form explicitly after ShowDialog call.
Custom MessageBox DialogResult
You are not comparing result of Show method with DialogResult.
Instead of using
if (CustomMessageBox.Show("Title", "TITLEEE", CustomMessageBox.CustomMessageBoxButtons.OkCancel) == CustomMessageBox.MsgBox.result.Yes)
Try using
if (CustomMessageBox.Show("Title", "TITLEEE", CustomMessageBox.CustomMessageBoxButtons.OkCancel) == DialogResult.Yes)
C# MessageBox dialog result
DialogResult result = MessageBox.Show("Do you want to save changes?", "Confirmation", MessageBoxButtons.YesNoCancel);
if(result == DialogResult.Yes)
{
//...
}
else if (result == DialogResult.No)
{
//...
}
else
{
//...
}
MessageBox with YesNoCancel - No & Cancel triggers same event
This should work fine:
Dim result As DialogResult = MessageBox.Show("message", "caption", MessageBoxButtons.YesNoCancel)
If result = DialogResult.Cancel Then
MessageBox.Show("Cancel pressed")
ElseIf result = DialogResult.No Then
MessageBox.Show("No pressed")
ElseIf result = DialogResult.Yes Then
MessageBox.Show("Yes pressed")
End If

You can use this custom Message Box

And you can call this Message Box
For Yes No Buttons
SLMessageBox messBox;
messBox = new SLMessageBox("Message", "Yes or No Message Box...!", SLMessageBox.MessageBoxButtons.YesNo, SLMessageBox.MessageBoxIcon.Information);
messBox.Show();
For Only Ok Button
SLMessageBox messBox;
messBox = new SLMessageBox("Message", "Ok Message Box...!", SLMessageBox.MessageBoxButtons.Ok, SLMessageBox.MessageBoxIcon.Information);
messBox.Show();
For Ok and Cancel Buttons
SLMessageBox messBox;
messBox = new SLMessageBox("Message", "Ok and Cancel Message Box...!", SLMessageBox.MessageBoxButtons.OkCancel, SLMessageBox.MessageBoxIcon.Information);
messBox.Show();
Edit:
And to check the result of the MessageBox what the user clicked
SLMessageBox messBox;
messBox = new SLMessageBox("Message", "Yes, No and Cancel Buttons Message Box...!", SLMessageBox.MessageBoxButtons.YesNoCancel, , SLMessageBox.MessageBoxIcon.Information);
messBox.Show();
messBox.OnMessageBoxClosed += messBox_OnDeleteMessageBoxClosed;
private void messBox_OnDeleteMessageBoxClosed(MessageBoxResult result)
{
if(result==MessageBoxResult.Yes)
{
//....
}
else if(result==MessageBoxResult.No)
{
//....
}
else
{
//...
}
}
C# How to make async MessageBox that returns DialogResult?
If you want to use the dialog result of a non-blocking message box and perform a job based on the result:
Task.Run(() =>
{
var dialogResult= MessageBox.Show("Message", "Title", MessageBoxButtons.OKCancel);
if (dialogResult == System.Windows.Forms.DialogResult.OK)
MessageBox.Show("OK Clicked");
else
MessageBox.Show("Cancel Clicked");
});
Note:
- The code after
Task.Runimmediately runs regardless of messagebox.
