Hi Renato,
Thank you for the provided project, but I deleted the link because the project contained a dev version of Telerik.Web.UI.dll and was available in the forum. Please, in the future in case you want to provide a project with a dev dll, open a new support ticket and attach it there.
I examined the project but I did not find the code which updates the grid there. I suggest to use the RadAjaxManager control in order to achieve the desired functionality, as shown in
this online demo which shows the desired scenario.
The RadAjaxManager should have the following setting:
| <telerik:RadAjaxManager ID="RadAjaxManager1" runat="server" OnAjaxRequest="RadAjaxManager1_AjaxRequest"> |
| <AjaxSettings> |
| <telerik:AjaxSetting AjaxControlID="RadAjaxManager1"> |
| <UpdatedControls> |
| <telerik:AjaxUpdatedControl ControlID="RadGrid1" /> |
| </UpdatedControls> |
| </telerik:AjaxSetting> |
| </AjaxSettings> |
| </telerik:RadAjaxManager> |
| |
The function, which refreshes the grid is the following:
| function refreshGrid(arg) |
| { |
| if(!arg) |
| { |
| $find("<%= RadAjaxManager1.ClientID %>").ajaxRequest("Rebind"); |
| } |
| else |
| { |
| $find("<%= RadAjaxManager1.ClientID %>").ajaxRequest("RebindAndNavigate"); |
| } |
| } |
| |
and it is called from within the RadWindow (by referencing its parent page).
The server handler for the ajax request is this one:
| protected void RadAjaxManager1_AjaxRequest(object sender, AjaxRequestEventArgs e) |
| { |
| if (e.Argument == "Rebind") |
| { |
| RadGrid1.MasterTableView.SortExpressions.Clear(); |
| RadGrid1.MasterTableView.GroupByExpressions.Clear(); |
| RadGrid1.Rebind(); |
| } |
| else if (e.Argument == "RebindAndNavigate") |
| { |
| RadGrid1.MasterTableView.SortExpressions.Clear(); |
| RadGrid1.MasterTableView.GroupByExpressions.Clear(); |
| RadGrid1.MasterTableView.CurrentPageIndex = RadGrid1.MasterTableView.PageCount - 1; |
| RadGrid1.Rebind(); |
| } |
| } |
| |
