[Solved] Postback UserControl Bind Data

[Felipe Saldana]

I have created a user control that contains a RadGrid inside of it.

I need to perform a postback from the client to bind the data.  The following does postback but I need an event so that I know that the postback is indeed the "RefreshGrid"

                __doPostBack("<%= gvProperties.UniqueID %>", "RefreshGrid");

I have followed:

http://www.telerik.com/help/aspnet/grid/grdmakepostbackajaxrequestfromusercontrolwebformmasterpage.html

http://www.telerik.com/help/aspnet-ajax/grdpostbackfromgridwithajaxenabled.html

and those two don't deal with posting back to the same UserControl.

I have implemented the IPostBackEventHandler but it does not fire at all.

Hello Felipe,

To initiate on client-side grid to refresh itself, you can call this JavaScript method:

function RefreshGrid()
{
  var masterTable = $find("<%= RadGrid1.ClientID %>").get_masterTableView();
  masterTable.rebind();
}

For further information please review this link.

I ended up doing the following

called a radWindow that when a save button is clicked do this:

    void btn_Click(object sender, EventArgs e)
    {
        try
        {
            if (!string.IsNullOrEmpty(this.ddlKeyword.SelectedValue))
            {
                ClientScript.RegisterStartupScript(Page.GetType(), "mykey", "CloseAndRebind();", true);
            }
        }
        catch (Exception ex)
        {
        }

    }


The javascript is below


        function CloseAndRebind(args)
        {
            GetRadWindow().Close();
            GetRadWindow().BrowserWindow.refreshGrid(args);
        }

        function GetRadWindow()
        {
            var oWindow = null;
            if (window.radWindow) oWindow = window.radWindow; //Will work in Moz in all cases, including clasic dialog
            else if (window.frameElement.radWindow) oWindow = window.frameElement.radWindow;//IE (and Moz as well)

            return oWindow;
        }

javascript on the control

           function refreshGrid(arg) {
               if (!arg) {
                   $find("<%= RadAjaxManager1.ClientID %>").ajaxRequest("Rebind");
               }
               else {
                   $find("<%= RadAjaxManager1.ClientID %>").ajaxRequest("RebindAndNavigate");
               }
           }

server side on the control

    protected void RadAjaxManager1_AjaxRequest(object sender, AjaxRequestEventArgs e)
    {
        if (e.Argument == "Rebind")
        {
            BindGrid();
        }
    }

RadAjaxManager control

   <telerik:RadAjaxManager ID="RadAjaxManager1" runat="server" OnAjaxRequest="RadAjaxManager1_AjaxRequest"  >
