[huynh]

Dear,
I use RadGrid with checkbox to select row .I set up a delete button outside the grid.When I click button,1 javascript confirm delete,this script return value exactly (true or false).But after,it can not jump to code behind althougn value return true or false.Is problem I set RadAjaxManangerProxy for delete button ?If I remove delete button out to RadAjaxManagerProxy,It works well.If I remove oncilck attribute ,it also delete well.How I can do?Please give me a solution.
This is my code:
 <telerik:RadAjaxManagerProxy ID="rproxyEmpList" runat="server">
        <AjaxSettings>
            <telerik:AjaxSetting AjaxControlID="UR001001grvEmployee">
                <UpdatedControls>
                    <telerik:AjaxUpdatedControl ControlID="UR001001grvEmployee" />
                </UpdatedControls>
            </telerik:AjaxSetting>
            <telerik:AjaxSetting AjaxControlID="UR001001btnDelete">
                <UpdatedControls>
                    <telerik:AjaxUpdatedControl ControlID="UR001001grvEmployee" />
                </UpdatedControls>
            </telerik:AjaxSetting>            
        </AjaxSettings>
</telerik:RadAjaxManagerProxy>
<telerik:RadScriptBlock ID="RadScriptBlock1" runat="server">
        <script language="javascript" type="text/javascript">  
            function ProcessDeleteClient(mesY,mesN)
            {
                var grid = $find("<%=UR001001grvEmployee.ClientID %>");
                var MasterTable = grid.get_masterTableView();
                var selectedRows = MasterTable.get_selectedItems();               
                if(selectedRows.length > 0)
                {
                    if(confirm(mesY) == true)
                    {
                        return true;        
                    }
                    else
                        return false;
                }
                alert(mesN);
                return false;  
             }
        </script>

    </telerik:RadScriptBlock>

Page Load(I set atttribute onlick):
     UR001001btnDelete.Attributes.Add("onclick", "return ProcessDeleteClient('" + Resources.Strings.UR001001msgConfirm + "','" + Resources.Strings.UR001001messAlert + "');");

Detelete button click event:
   protected void UR001001btnDelete_Click(object sender, EventArgs e)
        {
            helper.WriteLog(Constant.LogInfo, Resources.Strings.ListEmployee, Resources.Strings.UR001001btnDelete_Click, Resources.Strings.Initiation);
            try
            {

                DeleteItem();
                ListData = empFuc.GetListEmployee(Int32.Parse(SessionManager.Department), "", "", "");
                DisplayData(true);
            }
            catch (Exception ex)
            {
                helper.WriteLog(Constant.LogError, Resources.Strings.ListEmployee, Resources.Strings.UR001001btnDelete_Click, ex.Message);
            }
            helper.WriteLog(Constant.LogInfo, Resources.Strings.ListEmployee, Resources.Strings.UR001001btnDelete_Click, Resources.Strings.Success);

        }

Hi huynh,

Based on the code supplied, the code should reach the server. However, it is hard to determine what is causing it to fail. If the issue persists, please open a formal support ticket, and send us a small working project, demonstrating your logic and the unwanted behavior, for further testing.
