Hello Kenny,

According to my understanding, i suppose you would want to hide/show your grid according to the selected item in the combobox. If thats the case, check out the code below:
aspx:

<telerik:RadComboBox AutoPostBack="true" ID="RadComboBox1" runat="server" OnSelectedIndexChanged="RadComboBox1_SelectedIndexChanged">
        <Items>
        <telerik:RadComboBoxItem  Text="Show"/>
        <telerik:RadComboBoxItem Text="Hide"/>
        </Items>
</telerik:RadComboBox>

cs:

protected void RadComboBox1_SelectedIndexChanged(object o, RadComboBoxSelectedIndexChangedEventArgs e)
    {
       if (RadComboBox1.SelectedItem.Text == "Hide")
        {
            RadGrid1.Visible = false;
        }
        else
        {
            RadGrid1.Visible = true;
        }
    }

Thanks
Princy.

Hi Kenny,

Try rebinding the Gird after setting its visible property to true.

ASPX:

<telerik:RadGrid ID="RadGrid1" runat="server"  AllowPaging="True" PageSize="20" GridLines="None" OnNeedDataSource="RadGrid1_NeedDataSource" Visible="False">

 <telerik:RadComboBox ID="RadComboBox1" runat="server" AutoPostBack="True" OnSelectedIndexChanged="RadComboBox1_SelectedIndexChanged">
         <Items>
          <telerik:RadComboBoxItem  Text="Hide" runat="server" />
          <telerik:RadComboBoxItem  Text="Show" runat="server" />
         </Items>
        </telerik:RadComboBox>

CS:

  protected void RadComboBox1_SelectedIndexChanged(object o, Telerik.Web.UI.RadComboBoxSelectedIndexChangedEventArgs e)
    {
        if (RadComboBox1.SelectedItem.Text == "Hide")
            RadGrid1.Visible = false;
        else
        {
            RadGrid1.Visible = true;
            RadGrid1.Rebind();
        }

    }
