I have a RadTreeView placed in a PageView of RadTabStrip and tried to support keyboard access, but the TreeView won't be on focus when pressing Tab key. The TreeView is populated by datasource in DataBind. I want to focus on the first checkbox in the tree. Please advise.
<telerik:RadPageView ID="MCCCodePageView" runat="server" CssClass="tabpageview">  
<div style="margin:10px">  
   <div class="helpmodtitle">  
      <asp:Label ID="MCCCodePageViewHeader" runat="server" ></asp:Label> 
      <href="#"><img alt="Help" border="0" src="../images/helpicon.png"/></a> 
   </div> 
   <telerik:RadTreeView ID="TransCatTree" runat="server" 
    Width="95%" 
    Height="300" 
    CheckBoxes="true" 
    TriStateCheckBoxes="true" 
    CheckChildNodes="true" 
    BackColor="White"      
    Skin="Outlook" 
    BorderWidth="1px" 
    BorderColor="#94A7B5"      
    ShowLineImages="false" 
    MultipleSelect="false" 
    TabIndex="1" 
    AccessKey="W" 
    OnClientNodeChecked="TransCatTree_ClientNodeChecked">  
   </telerik:RadTreeView> 
</div> 
</telerik:RadPageView> 
The property TriStateCheckBoxes set True seems cause the issue not getting onFocus. If set as false, TreeView get focus on tab. How to enable TriStateCheckBoxes and get tab focus?

Hello Andrew Zhao,

The problem of focusing the first checkbox when TriStateCheckBoxes=true exists because the browser doesn't have native support for tristate checkboxes (they are not rendered as inputs). That's why this will be - no, we don't support that kind of scenario.

About the entire TreeView not getting focus on tab:
- This doesn't reproduce the issue. TreeView gets focus (but not on the first checkbox - it focuses the first node) and keyboard support is available as usual.

Hope this is helpful for you!
