Dear All,

Error comin on click of edit in the datagridview.

The error is"Invalid postback or callback argument. Event validation is enabled using <pages enableeventvalidation="true"> in configuration or <%@ Page EnableEventValidation="true" %> in a page. For security purposes, this feature verifies that arguments to postback or callback events originate from the server control that originally rendered them. If the data is valid and expected, use the ClientScriptManager.RegisterForEventValidation method in order to register the postback or callback data for validation."

Please help me to resolve it asap.

Regards,
vengaqua

Set the EnableEventValidation to False in the aspx page to get through this error.

@Shridhar panigrahi:EnableEventValidation = False will leads to form spoofing.Don't recommend this

@Jas24 : You are correct, it involves a security risk

@mvangaqua : Even when you changed "EnableEventValidation=False" nothing happens on click of edit, because it u need to handle the OnRowEdit event and set the row in question to edit mode. Below code might help:

protected void gridView1_OnRowEditing(object sender, GridViewEditEventArgs e)
{
GridView1.EditIndex = e.NewEditIndex;

}
