"Invalid Postback error"
-
Hi All, I am working with the tree view control for a secure site , which has numerous nodes. But i get an error when i click on a node to expand it.I can see this only attimes(I guess it happens only when i don't give time for a node to expand and click on some other node to expand). The error is like:- Invalid postback or callback argument. Event validation is enabled using in configuration or <%@ Page EnableEventValidation="true" %> in a page Can anyone tell me how to prevent it from happening :confused: Thanks & regards, Jeeva

For whatever reason, when EnableEventValidation="true" you have to wait for the page to finish loading before you click on a control in the page. Otherwise you get an errror. In your page directive you could set EnableEventValidation="false".
