custom validator

[Gernot]

Hi,
is it posible to use the required field validator with TreeView.
I need that the user selects min. one "Node".
Do i really need to use a custom validator?

Many Thanks!

Hello Alaeddin Gedik,

I believe that the best way is to use custom validator.
In its ClientValidationFunction you will find the instance of the treeview and check the length of the get_selectedNodes array.
You should do the same in its ServerValidate event handler.

I hope this helps.

Best wishes,
