Question

I am using a tooltip to display information when the user mouse_hovers on treeview nodes. That side of it works perfectly as expected. However I am having difficulty with the tooltip being visible when the mouse cursor leaves the treeview control. I have tried messing around and setting the properties such as AutoPopDelay, etc but I cannot seem to get this right. No matter what I do, when I move the cursor to the next control, the tooltip is obstructing the users view.

Any advice please?

Thanks.

I am guessing you are using the treeview’s NodeMouseHover event to render the tooltip, right? In that case you can use the ‘MouseLeave’ event to hide the tooltip once you leave the treeview.

void treeView1_MouseLeave(object sender, EventArgs e)
{
   myToolTip.Hide();
}
