    I am getting the following cast error,
    Cannot cast 'RadPanelBar1.FindItemByValue("QuickSearch").FindControl("txtFirstName")' (which has an actual type of 'Telerik.Web.UI.RadTextBox') to 'System.Web.UI.WebControls.TextBox'


    protected void imSearch_Click(object sender, EventArgs e)






    TextBox txtFirstName = (TextBox)RadPanelBar1.FindItemByValue("QuickSearch").FindControl("txtFirstName");






    <telerik:RadPanelBar runat="server" ID="RadPanelBar1" Width="100%" ExpandMode="SingleExpandedItem" Skin="Windows7" >






    <telerik:RadPanelItem Text="Quick Search" Expanded="True" runat="server" >






    <telerik:RadPanelItem runat="server" Value="QuickSearch" BorderColor="Red" >







    <asp:Label ID="lblSearch" style="text-align:center" runat="server" Text="First Name:" Font-Bold="True" />




    <telerik:RadTextBox ID="txtFirstName" runat="server" EmptyMessage="Search First Name" Skin="WebBlue" Width="130px"/>


    Can anybody tell me what I'm missing.

    Hello Eva,

    Since you are using the RadTextBox, you need to cast it as RadTextBox not as TextBox.
    protected void Button1_Click(object sender, EventArgs e)
           RadTextBox txtFirstName = (RadTextBox)RadPanelBarContratti.FindItemByValue("QuickSearch").FindControl("txtFirstName");
