I have a grid that allows edit and delete buttons for some fields.  Now, we're going to let non-admin users also see the same page, but want them to not be able to see the edit and delete buttons.

Any ideas where I should turn for that?

Hello,

I suppose that you have a column bound to user. If so, Check out the following code to disable controls in the grid for particular users.
aspx:
<telerik:GridBoundColumn DataField="User" UniqueName="User" HeaderText="Users"></telerik:GridBoundColumn> 
 
<telerik:GridTemplateColumn UniqueName="DeleteCol">  
        <ItemTemplate>  
            <asp:Button ID="DeleteBu8tton" runat="server" Text="Delete" CommandName="Delete" />             
        </ItemTemplate>          
  </telerik:GridTemplateColumn>  
  
<telerik:GridTemplateColumn UniqueName="EditCol">  
        <ItemTemplate>  
            <asp:Button ID="EditButton" runat="server" Text="Edit" CommandName="Edit" />              
        </ItemTemplate>        
  </telerik:GridTemplateColumn>  
 

cs:
   protected void RadGrid1_ItemDataBound(object sender, GridItemEventArgs e)   
    {           
        if (e.Item is GridDataItem)   
        {   
            GridDataItem dataItem = (GridDataItem)e.Item;   
            if(dataItem["User"].Text=="NonAdminUser")         
                  {                                                                                                                     
                     ((Button)dataItem["EditCol"].FindControl("DeleteButton")).Visible=false;                   
                     ((Button)dataItem["DeleteCol"].FindControl("EditButton")).Visible=false;                       
                         
                  }   
        }  
    }  

Thanks
Princy.

Thank you for the response. 

No, we don't have a column bound to the user.

I didn't develop this section, but the guy who did is on vacation for a week.  I've written most of the rest of the site, but am having trouble taking his code and making this part work.  We're using VB.Net for the back-end.

For the asp.net code, I've got the following.

 

<telerik:RadGrid ID="RadGrid1" runat="server" AllowPaging="True" AllowSorting="True" 
                    ShowStatusBar="true" AllowAutomaticDeletes="True" AllowAutomaticUpdates="True" 
                    DataSourceID="InviteeDataSource" GridLines="None" Skin="WebBlue" OnItemDataBound="RadGrid1_ItemDataBound" 
                    OnItemUpdated="RadGrid1_ItemUpdated" OnItemDeleted="RadGrid1_ItemDeleted" OnDataBound="RadGrid1_DataBound">  
                    <MasterTableView EditMode="PopUp" AutoGenerateColumns="False" DataKeyNames="WSID,UserID"

                        <Columns>

            'the item is in regular mode  
            'Dim dataItem As GridDataItem = CType(e.Item, GridDataItem)  
            'Dim txtEmail As String = CType(dataItem("Access_Level").FindControl("hideEmail"), Label).ToString()  
            'do something here   
            If UserIsAdmin Then  ' Function to check to see if the current user is an admin for this particular record.  
                Dim dataItem As GridDataItem = e.Item  
 
                Dim lb As New LinkButton  
                lb = dataItem("EditCommandColumn").FindControl("EditCommandColumn")  
                lb.Visible = False 
                lb = dataItem("DeleteColumn1").FindControl("EditButton")  
                lb.Visible = False 
            End If 
 

Basically, I have users who have 3 different levels.  If they are a "manager" or admin for the role, then they get the edit and delete buttons.  Otherwise, they just get the listing.

Hi,

I suppose Access_Level field in your database displays the user level. If thats the case then you can set the Access_Level field as the DataKeyName for your grid and try the following code:
aspx:
<telerik:RadGrid ID="RadGrid1" runat="server" AllowPaging="True" AllowSorting="True" ShowStatusBar="true" AllowAutomaticDeletes="True" AllowAutomaticUpdates="True" DataSourceID="InviteeDataSource" GridLines="None" Skin="WebBlue" OnItemDataBound="RadGrid1_ItemDataBound" OnItemUpdated="RadGrid1_ItemUpdated" OnItemDeleted="RadGrid1_ItemDeleted" OnDataBound="RadGrid1_DataBound">   
                    <MasterTableView EditMode="PopUp" AutoGenerateColumns="False" DataKeyNames="WSID,UserID,Access_Level" DataSourceID="InviteeDataSource">   
                       

cs:
     Protected Sub RadGrid1_ItemDataBound(ByVal sender As Object, ByVal e As GridItemEventArgs) 
         If TypeOf e.Item Is GridDataItem Then 
             Dim dataItem As GridDataItem = DirectCast(e.Item, GridDataItem) 
             If dataItem.GetDataKeyValue("Access_Level").ToString() = "Manager" Then 
                 DirectCast(dataItem("EditCommandColumn").Controls(0), ImageButton).Visible = False 
                 DirectCast(dataItem("DeleteColumn1").Controls(0), ImageButton).Visible = False 
             End If 
         End If 
     End Sub 

Thanks
Princy.
