RadTabControl bound to data source - how to access RadTabItems?

[s2uiguy]

Hi,

So I have a RadTabControl that is bound to a data source and the names of the individual tab items are bound to the Name property within that data source.
In some code-behind I need to be able to loop through the RadTabItems that are dynamically created as a result of being bound to this data source so that I can attach a tooltip to each RadTabItem.

I'm having difficulty figuring out how to access these RadTabItems.

I tried something like the following

foreach(RadTabItem item in MyTabControl.items) 
{
...
}

but that is just returning the data source objects and not the actual RadTabItem.

Any idea on how to get a handle on the actual RadTabItems that have been created....

Thanks you for any help.

Hello fortpointuiguy,

You can use the RadTabControl.ItemContainerGenerator.ContainerFromItem(object item) method. But you have to ensure that the containers (the Radtabitems) are already been generated. It`s a bit tricky because the Loaded event of the RadtabControl may not be sufficient, probably a Dispatcher is needed in most cases like so:

private void tabControl_Loaded(object sender, RoutedEventArgs e)
       {
           Dispatcher.BeginInvoke(() =>
           ForeachAllTabItems());
       }
       private void ForeachAllTabItems()
       {
           foreach (var item in this.tabControl.Items)
           {
               RadTabItem tabItem = this.tabControl.ItemContainerGenerator.ContainerFromItem(item as DataItem) as RadTabItem;
               if (tabItem != null)
               {
               }
           }
       }

Please let us know if this satisfies you or not.

Hi Petar,

Thanks for the reply.  I completely understand your solution so that's good but I'm having trouble figuring out where DataItem is defined (i.e. what assembly).

In the line
...ItemContainerGenerator.ContainerFromItem(item as DataItem)

What is a DataItem and in what assembly does that exist?

I apologize as this is probably a basic question and I've tried navigation the class documentation but had difficulty tracking down DataItem.

Any additional help would be appreciated.

Petar - I change DataItem to just be Object and I was able to access the RadTabItems.

Could you please explain the DataItems when you get a chance though.

Thanks!

Hello fortpointuiguy,

"DataItem" was the name of my business objects that I used to populate the RadTabControl. It is not part of framework or something. Just a class that I have defined. Please let me know if you need more info.

That makes total sense  - thanks.
