I have a winforms listbox control with vertical scroll,when I scroll it with mouse wheel it works perfectly but when I try scrolling with mouse click on vertical scroll it closes how to handle that events.
I didn't find a event in listbox with vertical scroll mouse click .can someone suggest why it is not working properly .
Although if I create a sample project of winforms with listbox vertical scroll works in both the cases.

I am using a Xceed WPF Grid with UI virtualization with horizontal and vertical Scrollbars. When I use the Scrollbar vertically or horizontally, with reusable UI components (VirtualizingStackPanel.VirtualizationMode="Recycling"), I want an event or property change other than from the Scrollbar.
My WPF window has WindowsFormshost which in turn has a WindowsForms Panel. The Panel has live preview from camera. I want to draw annotations(draw some rectngles, lines etc..)
on the image in the Panel. Is this possible in WPF with WindowsFormshost?
Any ideas?
No type of Scrolling works within scroll viewer control in silverlight
I would like to allow the user to
scroll using the mouse wheel
How can i do this?
It's there by default unless you're handling the mouse wheel event before it gets to the scroll viewer.
I am writing an WPF application, with drag and drop support within controls in the app, and also drag and drop between my desktop file and my app. I use adorner to change my mouse cursor.
The internal dragdrop operation between controls has no problem. The problem is dragdrop between desktop file and my app.
I set a DragEnter and DragLeave handler for my Window. When I drag a file into my app, DragEnter fired, but it's not just fired once, but keep firing with DragLeave alternatively on my application window.
What I already achieve is, I can manage to drag file into my app, with desired adorner; but if i keep holding the mouse and drag the file back to desktop, the adorner just stuck in the corner. I can't clear the adorner by using DragLeave, because the DragLeave event is firing non stop when I drag mouse in my app.
I want the DragLeave to fired only when the mouse cursor drag leave my application.
Any workaround?
Here is a possible workaround that you could do for this scenario.
DragDrop - DragEnter/DragLeave Events keep firing
I have a simple page with canvas control.
Inside canvas I have some SL controls like buttons, textboxes etc.
Also I cover the controls by semi-transparent Image control. So, when I click on some button, the click message doesn't reach the button, because I click on Image.
Is there a way to say the Image that it must not handle any gui events ?
p.s I use SL4
You should add IsHitTestVisible="False" to your image.
