Hello Guys,

Problem:
My save button won''t go to its event handler.

Scenario - 1:
A. I have a user control "GridControl" that has a datagridview that has an edit column per row.
B. Inside GridControl "my user control" I have implemented ajax to handle partial postback. I need this for paging and sorting.

<asp:UpdatePanel ID="Panel1" runat="server">
            
<contenttemplate>
     <asp:GridView ID="CommonGridView" runat="server"
          EmptyDataText="-- No Record Found --" Width="100%" CssClass="Grid">
    
</contenttemplate>

<triggers>
     <asp:AsyncPostBackTrigger ControlID="CommonGridView"/>                    
</triggers>

Scenario - 2:
A. In my aspx page i call the above usercontrol
B. In this aspx page, I have a div, textbox, and save button.
C. And when user click the edit button in the usercontrol the edit div whill showup.
D. When Click save the save button must go to its handler SaveButton_Click(object sender, EventArgs e){...}

Question:
When this: <asp:AsyncPostBackTrigger ControlID="CommonGridView"/>
Why is that if save button click it won''t go to SaveButton_Click?

But when this: <asp:PostBackTrigger ControlID="CommonGridView"/>
the save button event handler gets executed?

Thanks in advance for any help..
