    <br />
    <telerik:RadComboBox CheckBoxes="true" ID="RadComboBoxwithChk" runat="server">
        <Items>
            <telerik:RadComboBoxItem Text="ID" Value="ID" />
            <telerik:RadComboBoxItem Text="Name" Value="Name" />
            <telerik:RadComboBoxItem Text="ID1" Value="ID1" />

            if(item.Checked)
            RadGrid1.MasterTableView.GetColumn(item.Text).Visible = true;
            else
                RadGrid1.MasterTableView.GetColumn(item.Text).Visible = false;
        }

        RadGrid1.Rebind();
    }

protected void RadGrid1_NeedDataSource(object sender, GridNeedDataSourceEventArgs e)
    {
        DateTime dt = new DateTime();

        dynamic data = new[] {
                new { ID = 1, Name ="Name1", customdate=dt},
                new { ID = 2, Name = "Name2", customdate=dt},
                new { ID = 3, Name = "Name3", customdate=dt},
                new { ID = 4, Name = "Name4", customdate=dt.AddYears(2011)},
                new { ID = 5, Name = "Name5", customdate=dt}
            };

        RadGrid1.DataSource = data;
    }

let me know if any concern.
