</asp:TemplateField>
</Columns>
</asp:GridView>

以上GridView代；

protected void gvMaterialList_RowEditing(object sender, GridViewEditEventArgs e)
{
this.gvMaterialList.EditIndex = e.NewEditIndex;
GetMaterialList();
}
以上Edit事件代

[解决办法]
gvMaterialList_RowEditing这个事件有没有绑定GridView中啊，我以前就碰到过~~~
[解决办法]
<asp:ImageButton ID= "ImageButton1 " runat= "server " CausesValidation= "True " CommandName= "Update "
把CommandName= "Update "改成CommandName= "Edit "
