Refresh dont' work and delete don't refresh the grid

[Hans van Rijnswoud]

Hi,

I implemented a simple grid like your example : http://demos.telerik.com/ASPNET/prometheus/Grid/Examples/DataEditing/AllEditableColumns/DefaultCS.aspx

The problems are:
- When i click on the button refresh in the header of the grid, i can see the RadAjaxLoadingPanel but nothing append.
- When i click on the button delete, the row is deleted from my list of object but the grid is not refreshed.
Any idee of the problem?

Code aspx:

    <asp:Panel ID="PanelOverviewAddressType" runat="server" SkinID="PageContent">
               <asp:ScriptManager ID="ScriptManager1" runat="server"></asp:ScriptManager>
                <telerik:RadAjaxManager ID="RadAjaxManager1" runat="server">
                    <AjaxSettings>
                        <telerik:AjaxSetting AjaxControlID="RadGrid1">
                             <UpdatedControls>
                                    <telerik:AjaxUpdatedControl ControlID="RadGrid1" LoadingPanelID="RadAjaxLoadingPanel1"/>
                            </UpdatedControls>
                        </telerik:AjaxSetting>

        }

Extra question: how can i change the text of the button of a RadWindowManager?



Thanks.

Hello Edwin,

You can change the localization strings of the RadWindow control by using the following Javascript code that should be placed after the  RadWindowManager declaration:

Telerik.Web.UI.RadWindowUtils.Localization =
{
    "Close" : "Close",
    "Minimize" : "Minimize",
    "Maximize" : "Maximize",
    "Reload" : "Reload",
    "PinOn" : "Pin on",
    "PinOff" : "Pin off",
    "Restore" : "Restore",
    "OK" : "OK",
    "Cancel" : "Cancel",
    "Yes" : "Yes",
    "No" : "No"
};

Thanks
Princy.
