  Hi,

  I try to follow RadMenu Template Demo http://demos.telerik.com/aspnet-ajax/menu/examples/functionality/templates/defaultcs.aspx
  example.  But instead of using RadMenu, I use RadContextMenu.  The problem I have is I can't get the TextBox control Text in the template.  If I change it back to RadMenu, I am able to see the TextBox control Text.  Can anyone tell me what's the wrong of my code?  or if anyway to get around.  Any suggestion is appreciated.

  Here is my code snippet

  // Click the image button  to show context menu

  <asp:ImageButton ID="ibAdvanced" runat="server" ImageUrl="~/images/icons/16/View.gif" OnClientClick ="showMenu(event)" ImageAlign="AbsMiddle" ToolTip="Advanced Search" />

  // Rad Context Menu I defined here with Item Template

  <telerik:RadContextMenu runat="server" ID="rcmSearchMenu" Skin="Vista">

  <Items>

  <telerik:RadMenuItem Text="Advanced" CssClass="advSearch" PostBack="false">

  <ItemTemplate>

  <asp:ListBox id="lbField" Rows="1" Width="100px" SelectionMode="Single" runat="server">

  <asp:ListItem> A </asp:ListItem>

  <asp:ListItem> B </asp:ListItem>

  <asp:ListItem> C </asp:ListItem>

  </asp:ListBox>

  <asp:ListBox id="lbOperator" Rows="1" Width="100px" SelectionMode="Single" runat="server">

  <asp:ListItem> Greater </asp:ListItem>

  <asp:ListItem> Less </asp:ListItem>

  </asp:ListBox>

  <asp:RequiredFieldValidator ID="rfvAdvSearch" runat="server" ControlToValidate="tbAdvSearch" ValidationGroup="vgAdvSearch" Text="empty*" />

  <asp:TextBox ID="tbAdvSearch" runat="server" EnableViewState="true" />

  <asp:LinkButton ID="lkbAdvSearch" runat="server" CssClass="advSearch-button" OnClick="lkbAdvSearch_Click" OnClientClick="searchclick()" ValidationGroup="vgAdvSearch" ToolTip="Click to Search" EnableViewState="true" />

  <asp:ImageButton ID="ibCancel" runat="server" ImageUrl="~/images/icons/16/Cancel.gif" OnClientClick="hideMenu(event)" ImageAlign="AbsMiddle" ToolTip="Cancel" />

  </ItemTemplate>

  </telerik:RadMenuItem>

  </Items>

  </telerik:RadContextMenu>

  // the event when user click the Link Button control in template

  protected void lkbAdvSearch_Click(object sender, EventArgs e)

  {

  TextBox AdvSearchTextBox = (TextBox)((LinkButton)sender).NamingContainer.FindControl("tbAdvSearch");

  ListBox fieldListBox = (ListBox)((LinkButton)sender).NamingContainer.FindControl("lbField");

  ListBox operatorListBox = (ListBox)((LinkButton)sender).NamingContainer.FindControl("lbOperator");

  // No comiplation, no runtime error

  // But I am not getting the Text value I enter in Textbox, Also, I am not getting value of ListBox Item I selected either

  }

  Thanks

  Hi kevin,
  
  We used your code to create a simple test page, but we could not replicate the problem. Please, modify the attached test page so that the problem occurs and send it back to us via a support ticket. Or, let us know what is different in your case.
  
  All the best,
  Peter

  Hi Peter

  Basically I just rewrite the code by using your attached zip in a very simple web project.
  Below is the copy and paste of   Default.aspx, Default.aspx.cs ,  Default.aspx.designer.cs ,  style.css  and images used.
  I still can't see the textbox value/text I typed after click the button. 
  In the  event   lkbAdvSearch_Click., the Response only writes back "Text in TextBox-" to screen.

  Please Advise.

  Thank you

  Hi kevin,
  
  We still cannot replicate the problem locally. To be able to give you a specific solution we will need a simple working demo project which we can run without modification and test locally.
