I am creating several buttons in the the commandItemTemplate, I am using these to export tp csv plus many other things (I could use the commandItemSettings but dont want to). The problem I am having is that I cannot find the buttons in the code behind. My code is as follows.

    
            <telerik:RadAjaxLoadingPanel runat="server" ID="progressLoader" MinDisplayTime="1500" InitialDelayTime="1000" Skin="Default"></telerik:RadAjaxLoadingPanel> 
        
            <telerik:RadAjaxPanel runat="server" ID="rap_panel1" LoadingPanelID="progressLoader">  
        
                    <telerik:RadGrid ID="RadGrid1"    
        
                                     runat="server"   
        
                                     GridLines="Vertical" 
        
                                     ShowGroupPanel="True"   
        
                                     PageSize="18"   
        
                                     AllowSorting="true"   
        
                                     AllowPaging="true"   
        
                                     AutoGenerateColumns="false"   
        
                                     EnableHeaderContextMenu="true"

                    </telerik:RadGrid> 
        
            </telerik:RadAjaxPanel>

    
                Protected Sub RadGrid1_ItemCreated(ByVal sender As Object, ByVal e As Telerik.Web.UI.GridItemEventArgs) Handles RadGrid1.ItemCreated  
        
                    Dim item As GridCommandItem = TryCast(e.Item, GridCommandItem)  
        
                    If item IsNot Nothing Then 
        
                        Dim btn As Button = TryCast(item.FindControl("btn_excel"), Button)  
        
                    End If 
        
                End Sub

Any help would be much appreciated.

Hello Russell,

I am happy to help you. The following code snippet will be useful for you in achieving this.

VB.NET:

    
             Protected Sub RadGrid1_ItemCreated(sender As Object, e As GridItemEventArgs) 
        
                If TypeOf e.Item Is GridCommandItem Then 
        
                    Dim item As GridCommandItem = TryCast(e.Item, GridCommandItem) 
        
                    If item IsNot Nothing Then 
        
                        Dim btn As LinkButton = TryCast(item.FindControl("btn_excel"), LinkButton) 
        
                    End If 
        
                End If 
        
             End Sub

Thanks,
