Hi Gokul,

I guess you want to display the DefaultMessage of the second RadDropDownList on button click. Please check the following C# code I tried which works fine at my end.

ASPX:

<telerik:RadDropDownList ID="RadDropDownList1" runat="server" DefaultMessage="Please Select">
    <Items>
        <telerik:DropDownListItem runat="server" Text="Item 1" />
        <telerik:DropDownListItem runat="server" Text="Item 2" />
        <telerik:DropDownListItem runat="server" Text="Item 3" />
    </Items>
</telerik:RadDropDownList>
<asp:Button ID="Button1" runat="server" Text="Clear" OnClick="Button1_Click" />

C#:

protected void Button1_Click(object sender, EventArgs e)
{
    RadDropDownList1.SelectedIndex = -1;
}

Thanks,
Shinu.
