    Hi Aditya,

    I am not sure if I understand your scenario correctly. Do you need to add a list of different controls in the RadExpander's Content based on all records in a table or you need to base the Content of the RadExpander on a single record from the table?

    In both scenarios you will need to add some custom logic to create the controls based on the business data. For example if you need to fill the RadExpander.Content with different controls based on all the data in a table, you can take advantage of Telerik's ItemsControl. You can use it as the RadExpander.Content and use its ItemTemplateSelector property to choose a template for its items based on the business data. I attached a sample project illustrating this approach.

    Have a look at it and let us know if this is what you had in mind.

    Best wishes,

    Hello Steve

    If you take a closer look at the ItemsSource of the RadExpander you will see that it contains all three controls. This is why the RadExpander visualizes all three templates at the same time.
