Thank you for contacting us.
Currently, this feature is not supported by RadListView
. However, as this sounds like a reasonable functionality, I have logged it to PITS as a feature request and we will implement it in a future release. Here is the link to the PITS item
. For the time being, you can enable the ThreeState
behavior of RadListView
's items by adding a visual style to the indeterminate state of the items in the theme you are using and using the following code to apply it:
sender, Telerik.WinControls.UI.ListViewVisualItemCreatingEventArgs e)
I have attached the theme package used in the above snippet along with a screenshot which demonstrates how to add style to the indeterminate state.
Your Telerik points have been updated for your feature request.
I hope you find this useful.
