Drag-n-Drop

[VR]

I am trying to use a custom cursor during drag-drop
operation between 2 ListViews. So, I have a code that at
the time GiveFeedback() is called creates a new cursor
based on the icon and text of the dragged item:

private void listView2_GiveFeedback
(
object sender,
System.Windows.Forms.GiveFeedbackEventArgs e
)
{
string szText = ...;
Bitmap oBitmap = new Bitmap(...);
Cursor oNewCursor = CreateCursor(oBitmap, szText);

e.UseDefaultCursors = false;
this.Cursor = oNewCursor;
}


The problem is that once I stop dragging the item, my
mouse cursor turns back to normal, when it's over listview
controls, but over the form it still looks like the custom
cursor I created.

I suspect that somewhere I have to set UseDefaultCursors
back to true, as well as I should set the cursor itself
back to Cursors.Arrow.

The question is where should I do it? Which other event
has the same parameters so I would have access to
UseDefaultCursors?

Thanks,
VR

Hi VR,

If you want to set the cursor back to default when it is not on the
LIstView control, you can
determine if the e.Effect is DragDropEffects.Move.

Something like this:

private void Form1_GiveFeedback(object sender,
System.Windows.Forms.GiveFeedbackEventArgs e)
{
e.UseDefaultCursors =false;
try
{
if((e.Effect & DragDropEffects.Move )==DragDropEffects.Move )
{
Cursor.Current=new Cursor("3dgarro.cur");
}
else
{
Cursor.Current =Cursors.Default ;
}
}
catch(Exception ex)
{
MessageBox.Show (ex.Message );
}
}

HTH.
