Hi,
When I try to use UpdatePanelAnimationExtender I'm always getting the error Object reference not set to an instance of an object.
My project worked fine until I updated Ajax Control Toolkit to version 15.1.4
Thank you,
Comments: Hi, I've found what causes the exception but I don't know why... If I remove the following code, the page renders with no errors (obviously buttons stop working) <Triggers> <asp:PostBackTrigger ControlID="btn_Imprimir" /> <asp:PostBackTrigger ControlID="btn_ImprimirExcel" /> </Triggers> I don't know how to solve it. Thanks
