Hi,

You would put them inside a Panel and then set the Panel as a trigger. Setting a parent control as a trigger automatically means set all children controls as triggers.

Thanks

How?

Code: HTML/ASPX
<eo:CallbackPanel runat="server" ID="qwe" UpdateMode="Conditional" ClientSideBeforeExecute="test" AutoDisableContent="True" Triggers="{ControlID:pane;Parameter:}">
        <asp:Panel runat="server" ID="pane">
            <asp:Button ID="Button1" runat="server" />
            <asp:TextBox ID="TextBox1" runat="server"></asp:TextBox>
            <asp:Button ID="Button2" runat="server" />
        </asp:Panel>
        </eo:CallbackPanel>


or
Code: HTML/ASPX
<asp:Panel runat="server" ID="pane">
        <eo:CallbackPanel runat="server" ID="qwe" UpdateMode="Conditional" ClientSideBeforeExecute="test" AutoDisableContent="True" Triggers="{ControlID:pane;Parameter:}">
            <asp:Button ID="Button1" runat="server" />
            <asp:TextBox ID="TextBox1" runat="server"></asp:TextBox>
            <asp:Button ID="Button2" runat="server" />
        </eo:CallbackPanel>
        </asp:Panel>


All parts not worked.

Thanks!

Hi,

The first one is the correct form, however the current version only works with parent control that implements INamingContainer. Panel does not implement this interface so it does not work. We have posted a new build that removed this restriction. Please see your private message for the download location.

Thanks!

I was install new version. Thanks.
With panel it's worked.
But if i set UpdateMode="Conditional" then panel is not updated.
If in server side on Button1_CLick write qwe.update() then i take this message:
"The current request is not a callback request triggered by EO.Web Callback or EO.Web.CallbackPanel."

But if i set UpdateMode="Self" then all worked but i can't update one callbackpanel data from other callbackpanel.

Hi,

That's the normal behavior. You don't need to call Update when the request is a normal reques.t because everything in the page, including all CallbackPanels, will be updated. You can call CallbackPanel1.IsCallback to check whether the current request is callback and only call Update when IsCallback returns true.

Thanks

if i rise event from button1 or button2 (this buttons inside qwe callbackpanel) then event handled on the server, but UI not updated. If on server side in button1_click or button2_click i write
if (qwe.IsCallback)
qwe.Update();
then all worked. If not write this, then site crash with error

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.


I think it's not normal behavior. I think that qwe.update need call when i handle event from different callbackpanel (not from qwe).

This is correct. qwe.Update need to be called when you handle event from any CallbackPanel. However qwe.IsCallback returns true as soon as any CallbackPanel triggers. In another word, as soon as the current page is from a CallbackPanel, callback1.IsCallback would return true, callback2.IsCallback would return true, every CallbackPanel's IsCallback would return true. So it does not matter which one's IsCallback you are checking.
