Event for LinkCreating Issue

Hi Stoya,

I have some validation code in the LinkCreating event handler. I set e.Cancel to true and display a message box if the link is not allowed.

The problem is that the LinkCreating event is raised
more than onece and the message box is shown 2 times.

How can avoid this? Thanks a lot.

Hi,

You could call e.CancelDrag() to stop the link creation completely. Otherwise LinkCreating is raised for each mouse move, and setting e.Cancel = true just changes the cursor to the Stop icon, and has the effect of cancelling the operation only when raised for the last time (after the mouse button is released). So, another way to handle this is show the message box only if you detect that the mouse button state is 'up'.
