If you create a global TabTemplate (need to have a close button) any images that are assigned to the tab don't show up unless the tab is hovered over. The other issue is the icon (image) shows up in the far right of the tab, not left of the text as expected and documented.

    
              <telerik:RadTabStrip ID="RadTabStrip1" runat="server" SelectedIndex="0"   
        
                    Skin="Vista">  
        
                     <TabTemplate> 
        
                        <%# DataBinder.Eval(Container, "Text") %> 
        
                      </TabTemplate> 
        
                     <Tabs> 
        
                        <telerik:RadTab runat="server" Text="Demand" ImageUrl="~/Images/icons/Demand.gif">  
        
                        </telerik:RadTab> 
        
                        <telerik:RadTab runat="server" Text="Drafts"  ImageUrl="~/Images/icons/Drafts.gif">  
        
                        </telerik:RadTab> 
        
                    </Tabs> 
        
                </telerik:RadTabStrip>

Any idea on how to make the Image show up in the proper place at the proper time (load)?

Hi Doug,

Unfortunately you have discovered a bug in RadTabStrip. The ImageUrl should be rendered initially when TabTemplate is specified. Now it is rendered at the client side when the user selects or hovers the tab. I have logged this bug and we will release a hotfix soon. I will update this forum thread once ready.

Just thought I would let you know that I never got the build with the fix in it. Not sure what is going on.

There appears to be another issue with this now. If you try to add a tab dynamically the text doesn't show up when added.

    
             Dim rootTab As RadTab = New RadTab  
        
             rootTab.Text = _TabText   
        
             rootTab.Value = TableName 
        
             rootTab.Selected = True 
        
             rootTab.ImageUrl = GetImageURL("Icons/" & CTableManager.GetTableIcon(TableName))  
        
             RadTabStrip1.Tabs.Add(rootTab)

After the tabstrib has been reloaded on a postback after the tab is added it then shows up properly.

Right now my work around is instead of adding the tab directly, I add it into the DB record that contains the tab configuration (to maintain tabs across sessions) and then reload the entire tab strip everytime a new tab is added by the user. It isn't pretty, but I have it working for now. But it would be nice if the Text property of the RadTab is properly applied when using a tab template with dynamic generation.

Thanks,

Doug

Edit: I did discover that calling RadTabStrip1.DataBind() after the tab is added seems to refresh the tabstrip enough to show the properly configured tab.

I have a similar problem. I use user control inside a template. The user control has texts and images in it but
the rad tab shows nothing. I have also called Databind explicily. The following is my code

telerik:RadTab PageViewID="RadPageViewDocuments">

<uc:DocumentTab runat="server" Text="<%$ Resources:TextStrings, DocumentWorkspace %>"

ToolTip="<%$ Resources:TextStrings, DocumentWorkspace %>" ID="UserControlDocumentTab"

NumberOfItems="2" MaximumNumber="99" />

</TabTemplate>

</telerik:RadTab
