RadJumpList.ItemsSource

[Paras]

I have a RadJumpList control on my page in a WP7.x application. The ItemTemplate for this control is set to a complex structure like below:

<telerikDataControls:RadJumpList.ItemTemplate>
 <DataTemplate>
 <Grid>
  <Image Name="img1" />
  <TextBlock Name="tbVal1" />
  <TextBlock Name="tbVal2" />
  <TextBlock Name="tbVal3" />
 </Grid>
 </DataTemplate>
</telerikDataControls:RadJumpList.ItemTemplate>

From what I can tell the RadJumpList.ItemsSource property can only be set to a List<string>. How do I accomplish the task of assigning a value for all the controls in the ItemTemplate while limited to List<string> only? I was hoping to assign a List<MyClass> to the ItemsSource property where 'MyClass' contains elements/properties for all the controls in the ItemTemplate.

Hi Paras,

The ItemsSource property of the RadJumpList can be set to a collection of any type of object. Please refer to the attached project and let me know if it helps. I'd be glad to assist you further.

Hi Kiril,

While your sample solution works, my project still throws an error like:
