Refresh controls out of ajax panel with a control in ajax panel

[Silvio Silva Junior]

Hello everybody.

I have a simple question.

I have a page with 1 textbox and 1 grid.

My grid is in an ajax panel, and my textbox not. When I make some action in grid (insert, update, delete) I'm trying to change the textbox's value, in the event, like:

Grid Update Event:
TextBox1.Text = "blablabla";

but I can't. What's the best solution for this my friends?

Thanks.

Regards.

Hi,

#1:
I tried following approach in my application for a similar scenario.

c#:

protected void RadGrid1_ItemCommand(object source, GridCommandEventArgs e)

{

string script = "document.getElementById('" + TextBox1.ClientID + "').innerText ='TestString'";

ScriptManager.RegisterStartupScript(this.Page, this.Page.GetType(), "show", script, true);

}

#2:
Another suggestion is to use RadAjaxManager. The RadAjaxPanel functionality can be simulated completely by the manager - simply replace the AJAX Panel with an ASP:Panel.

aspx:

     <telerik:RadAjaxManager ID="RadAjaxManager1" runat="server">
           <AjaxSettings>
               <telerik:AjaxSetting AjaxControlID="RadGrid1">
                   <UpdatedControls>
                       <telerik:AjaxUpdatedControl ControlID="Panel" />
                       <telerik:AjaxUpdatedControl ControlID="TextBox1" />
                   </UpdatedControls>
               </telerik:AjaxSetting>
           </AjaxSettings>
       </telerik:RadAjaxManager>


       <asp:Panel ID="Panel" runat="server">
            <telerik:RadGrid ID="RadGrid1" AllowSorting="True" PageSize="20" ShowGroupPanel="True"
                AllowPaging="True" AllowMultiRowSelection="True" AllowFilteringByColumn="true"
                AutoGenerateColumns="true" EnableViewState="true" runat="server" GridLines="None"
                 OnItemCommand="RadGrid1_ItemCommand">
            </telerik:RadGrid>
        </asp:Panel>

        <asp:TextBox ID="TextBox1" runat="server"></asp:TextBox>

The modified version of the code will perform the same task as if you use RadAjaxPanel instead of manager: I tried these two approaches to get it works.



Hope this helps,

Hello Princy, and thanks for the answer.

The first suggestion doesn't work.

With the second suggestion, I got this error when I load the page: 

Script control '' is not a registered script control. Script controls must be registered using RegisterScriptControl() before calling RegisterScriptDescriptors().
Parameter name: scriptControl

My aspx file is like this:

              <telerik:RadAjaxManager ID="RadAjaxManager1" runat="server">
               <AjaxSettings>
                   <telerik:AjaxSetting AjaxControlID="MyGrid">
                       <UpdatedControls>
                           <telerik:AjaxUpdatedControl ControlID="Panel" />
                           <telerik:AjaxUpdatedControl ControlID="TextBox1" />
                       </UpdatedControls>
                   </telerik:AjaxSetting>
               </AjaxSettings>
           </telerik:RadAjaxManager>
           <telerik:RadAjaxLoadingPanel ID="RadAjaxLoadingPanel" runat="server">
            </telerik:RadAjaxLoadingPanel>
            <telerik:RadAjaxPanel ID="RadAjaxPanel" runat="server" LoadingPanelID="RadAjaxLoadingPanel">
           <asp:Panel ID="Panel" runat="server">
                MyGrid
            </asp:Panel>
             </telerik:RadAjaxPanel>

And I tryed something like this:

<telerik:RadAjaxManager ID="RadAjaxManager1" runat="server">
               <AjaxSettings>
                   <telerik:AjaxSetting AjaxControlID="MyGrid">
                       <UpdatedControls>
                           <telerik:AjaxUpdatedControl ControlID="Panel" />
                           <telerik:AjaxUpdatedControl ControlID="TextBox1" />
                       </UpdatedControls>
                   </telerik:AjaxSetting>
               </AjaxSettings>
           </telerik:RadAjaxManager>
           <asp:Panel ID="Panel" runat="server">
                MyGrid
            </asp:Panel>

But I got the same error.

What am I doing wrong?

Regards.
