Refresh Grid automatically?

[Mike]

Is there a setting similar to a meta refresh in the grid so that it would refresh every 10 minutes or so?

Hello George,

RadGrid does not provide such functionality, however, you can use RadAjaxTimer:

Dimo,

I treid and got an error!

Parser Error Message: Unknown server tag 'telerik:RadAjaxTimer'.

Any other ideas would be helpful.

Thanks!

I have found an eligant yet simple solution, here is what I put in the aspx page

<asp:Timer ID="Timer1" OnTick="Timer1_Tick" runat="server" Interval="30000" />
<asp:Label ID="Label1" runat="server" Text="Grid not refreshed yet."></asp:Label><br />

In between here is your radGrid

<telerik:RadAjaxManager ID="RadAjaxManager1" runat="server" OnAjaxRequest="RadAjaxManager1_AjaxRequest" KeepInScreenBounds="True" Modal="true" VisibleStatusbar="false">
 <AjaxSettings>
   <telerik:AjaxSetting AjaxControlID="Timer1">
      <UpdatedControls>
          <telerik:AjaxUpdatedControl ControlID="RadGrid1" LoadingPanelID="RadAjaxLoadingPanel1" />
      </UpdatedControls>
    </telerik:AjaxSetting>
 </AjaxSettings>
</telerik:RadAjaxManager>
<telerik:RadAjaxLoadingPanel ID="RadAjaxLoadingPanel1" runat="server" Height="75px" Width="75px" Transparency="20">
     <img alt="Loading..." src='<%= RadAjaxLoadingPanel.GetWebResourceUrl(Page, "Telerik.Web.UI.Skins.Default.Ajax.loading.gif") %>' style="border: 0;" />
</telerik:RadAjaxLoadingPanel>

Code Behind

protected void Timer1_Tick(object sender, EventArgs e)
{                                                                                               Label1.Text = "Grid Refreshed at: " + DateTime.Now.ToLongTimeString();
  BindGrid();
}

It is a slightly modified version of this code:
