 I Create A custom Gridview.

I need to add som custom properties to this control, but when I add the property I get error in design view  (it works fine in website):

'ds' could not be set on property 'CssClass_Main'

 this is my code: 

1    namespace Onev_Controls
2    {
3        public partial class DataView : GridView
4        {
5    
6            private string _CssClass_Main = "DataView_Main";
7            public string CssClass_Main
8            {
9                get
10               {
11                   if (ViewState["DataView_CssClass_Main"] == null)
12                   {
13                       ViewState["DataView_CssClass_Main"] = _CssClass_Main;
14                       return ViewState["DataView_CssClass_Main"].ToString();
15                   }
16                   return ViewState["DataView_CssClass_Main"].ToString();
17               }
18               set { ViewState["DataView_CssClass_Main"] = value; }
19           }
20        }
21   }

         <Onev:DataView ID="DataViewID" runat="server"  CssClass_Main="ds">
        </Onev:DataView>

Hi,

It works fine on my side. What's your Visual Studio edition?
