I am using UltraComboEditior of Infragistics Conrtrols in C# winform application, I want to show a messageBox when UltroComboEditior got focues by MouseClick or KeyBoard Tab button, how can I do it? Any suggestions ? I tried BeforeDropDown but it is called only when we click on arrow button to show drop down list but I am using only drop down with auto complete option set to be true.
UltraComboEditor control has "Enter" event which fires when the control becomes the active control of the form, and this event will fire in both situations - when the control got focus by using your Tab key, and when you are using your mouse.
I hope that this will help you to achieve your goal.
Doesn't it inherit the OnGotFocus event which you can subscribe to?

I have a custom ComboBox which opens a separate control when you click on the arrow of the ComboBox. I would like to call the 'LostFocus' event handler to close the custom control when you lose focus of the ComboBox.
This works fine if you click onto another control such as a text box, however doesn't fire if you click on the background of the form.
I want to mimic the functionality of when you click off and close the dropdown of a normal combobox.
Take a bool variable at Form level and make it true during combobox enter(GotFocus) event. InLeave(LostFocus)event ofcombobox, make itfalse`.
Subscribe to Form MouseClick event and check bool variable in this event. if true , call combobox leave event here.
I'm new to Visual Studio and am converting a C# console app to VS so that I can give it a GUI. The GUI piece is definitely a learning curve.
I have a main Form1 with Tab1 and Tab2. I can call this.AcceptButton, but it only appears to be at the form level. Is there a way for each tab to have an AcceptButton? I can't call this.Tab1.AcceptButton, however when I am in Tab2, the function of AcceptButton doesn't seem to trigger. Is it because the button doesn't exist on the tab that is in focus?
I could certainly forgo using AcceptButton if there's not a clean way to do this, but it would increase the usability of the application.
Thanks in advance!
You can listen to SelectedIndexChanged event on your TabControl. So whenever tab is change this event will fire and you can use assign another button to AcceptButton.
Have a look at this: Change accept button with tabs
I have a custom UserControl. I want to use it in a few different products, so I want something that can be implemented inside of the UserControl itself. I want to know when the user has clicked outside of the bounds of the UserControl so that I can hide it, similar to a ComboBox. How can I do that?
I tried handling the click event, but it only seems to fire if the click occured within the bounds of the control.
That's what the Capture property is designed to do. Set it to true and all mouse messages are routed to your control, even if it moves out of the window bounds. Check the e.Location property in the MouseDown event.
Hm, you may be able to accomplish what you want by listening to the GotFocus/LostFocus events. ComboBoxes give the drop downs focus when they open and close them when they lose focus.
do this
Select all controls on your form including form
In Property Window select MouseClick event
Now enter below Code in Common_MouseClick
Code:
if (!sender.Equals(yourControl))
{
yourControl.Visible=false;
}
I am writing an app where the user should be able to alter the action of a button.
The user should right-click a button, and choose an option from a pop-up context menu. Once the choice has been made the button will perform a different action when the user uses a normal click.
I've already gotten the "Click" event working for a normal button click, however the "MouseClick" event handler isn't working correctly.
The "MouseClick" event gets activated on regular left-clicks, but never get's called for right-click.
Is there some default event handling being performed that is ignoring that right-click?
I'm sorry to say that this would be a serious UI blooper. Perhaps it would make more sense to add a small combobox next to the button.
Perhaps something like this?

If you want to display a context menu with actions to choose from it should be enough to assign a ContextMenuStrip to the ContextMenuStrip property. There is usually no need to manually handle the mouse events for that.
surely it would be better to implement it on the MouseDown event rather than the MouseUp event. i dont understand how this is much different from MouseClick event
edit: Just tried this and it works a treat :)
In Button (and certain other controls), the MouseClick event is only fired for the left button. Refer to MSDN.
If you want to know about the right button, respond to the MouseUp event--though as other posters have pointed out, this isn't a great UI idiom.
Use the Mouse UP event... test that Button.X and Button.Y are within the size of the button otherwise you have moved the mouse away from the button.

I would like to intercept the event in a .NET Windows Forms TabControl when the user has changed tab by double-clicking the tab (instead of just single-clicking it).
Do you have any idea of how I can do that?
The MouseDoubleClick event of the TabControl seems to respond just fine to double-clicking. The only additional step I would do is set a short timer after the TabIndexChanged event to track that a new tab has been selected and ignore any double-clicks that happen outside the timer. This will prevent double-clicking on the selected tab.
For some reason, MouseDoubleClick, as suggested by Jason Z is only firing when clicking on the tabs and clicking on the tab panel does not do anything, so that's exactly what I was looking for.
How about subclassing the TabControl class and adding your own DoubleClick event?
