hi,

If I set a ToolTip for a TextBox, then in runtime after clicking inside the TextBox, the tooltip isn't displayed anymore.

It's easily reproducable - just create a win forms app,drop a TextBox and a ToolTip, set the TextBox's "ToolTip on ..." text to some text, and run. If you click the TextBox, the ToolTip doesn't work anymore.

Another thing -I wanted to force a ToolTip to be displayed in response to a key press of a text box (with something like "An invalid key was pressed"). I use the ToolTip's Show() method. However - if the ToolTip's IsBalloon = true, then if the mouse's cursor is within the TextBox, sometimes the toolTip isn't displayed at all (after calling Show) and sometimes it's displayed in weird locations.

Is there a workaround to the 2 above?

thanks

I'm not sure about the (default) behaviour of tooltip and their appearance...

To me it seems that an ErrorProvider control is more suitable for notifying the user about invalid data though...

btw,I'm using.net 2 on WindowsXP (default xp theme)
