Hi,
I have 2 dropdown boxes that default to ALL.  The 2nd dropdown box is populated based on the selection from the first dropdown.

Can somebody please tell me how I can hide the All option in the 2nd dropdown when an item from the first dropdown is selected.

Thanks

aspx.   
<div <asp:Label  ID="lbldrop2" runat="server">drop2</asp:Label>
                    <telerik:RadComboBox ID="drop2"    runat="server"></telerik:RadComboBox>

code behind

    public static void drop2(RadComboBox drop2, int drop2Id)
        {

            Drop2.DataSource = Drop2Data(Drop2Id).Data;
            Drop2.DataTextField = "Value";
            Drop2.DataValueField = "Key";

            droop2.DataBind();
--ONLY want to display if dropdown 1 does not have an item selected            
drop2.Items.Insert(0, new RadComboBoxItem("All", "0"));
        }

        </div>

Try this:

if(Drop1.SelectedIndex != 0) //In here, we assume that index "0" of "Drop1 is "All"
{
    Drop2.Items.Insert(0, new RadComboBoxItem("All", "0"));
}

Sorry it should be corrected as follows (typo)

if(Drop1.SelectedIndex == 0) //In here, we assume that index "0" of "Drop1 is "All"
{
    Drop2.Items.Insert(0, new RadComboBoxItem("All", "0"));
}

or try this:
if(Drop1.SelectedIndex == 0)
{
 for (int i=0;i<Drop2.Items.Count;i++)
 {
   Drop2.Items[i].Enabled=false;
 }
}
