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(); 
        } 
 
    }
