在内容页面后面的代码中获取Masterpage的Telerik RadToolBar

Question

I am now using Telerik AJAX to develop a ASP.NET web form.

There is a Telerik RadToolBar control in the master page:

 ... <td width="100%"> <div class="toolDiv"> <telerik:RadToolBar ID="tbToolbar" runat="server" AutoPostBack="True" OnButtonClick="Toolbar_ButtonClick" OnClientButtonClicking="Toolbar_ClientButtonClicking" /> </div> </td> ... 

For some reason I would like to get this toolbar control in one of the content page code behind using this master page, however I try

Master.FindControl("tbToolbar")

does not give me the toolbar control object, I also tried MainMasterPage.FindControl() and have no luck.

Is there a proper way to achieve what I want to do here? Thanks

EDITED:

My tbToolbar is located in Master Page as structure at below:

 <asp:Content ID="content" ContentPlaceHolderID="myPlaceHolder" runat="server"> ... <table> <tr> <td> <table> <tr> <td> <div> <telerik:RadToolBar ID="tbToolbar"> </asp:Content> 

EDITED2: (Solution)

As suggested by the accepted answer, I add a class to recursively find my control, I post it here in case anyone found it useful:

 private class ControlFinder<T> where T : Control { private readonly List<T> _foundControls = new List<T>(); public IEnumerable<T> FoundControls { get { return _foundControls; } } public void FindChildControlsRecursive(Control control) { foreach (Control childControl in control.Controls) { if (childControl.GetType() == typeof(T)) { _foundControls.Add((T)childControl); } else { FindChildControlsRecursive(childControl); } } } } protected void Page_Load(object sender, EventArgs e) { if (!IsPostBack) { ControlFinder<RadToolBar> controlFinder = new ControlFinder<RadToolBar>(); controlFinder.FindChildControlsRecursive(Master); RadToolBar toolBar = controlFinder.FoundControls.FirstOrDefault(); // my logic // if(toolBar != null) ... } }

If your control "tbToolbar" is inside ContentPlaceHolder then you have to first find the ContentPlaceHolder by id and then you have to find your control from that ContentPlaceHolder. Take a look at below link:

To reference a control on the master page

if control still can't be found then google for Find ASP.NET control recursively.
