ListBox exeption [SOLVED]
Posted: Sun Oct 25, 2015 12:59 pm
Hello,
sometimes ...
I have a ListBox and I change the ItnesSource and set the Visiblity on / off and then, sometimes, i got a exception in :
in Windows and JavaScript and under JavaScript I see that "this._itemsToDataTemplatedRenderedElement" is undefined ...
Under Windows I got a "System.Collections.Generic.KeyNotFoundException" ...
The ItemsTemplate is a Button ...
Regards,
Uwe
