Hi Shantesh,

After further researching the matter I have devised a way to set the focus on the WebDropDown's input shortly after a node in WebDataTree has been clicked, expanded or collapsed. Attached is my test sample for your consideration.

Please let me know if this helps.

Hi Petar

Thank You for the replay .  Can you please give me the possible solution for this scenario i.e without using  WebdataTree how can I achieve this . If possible please send me sample project

Hi Shantesh,

I have received word back from development regarding this scenario:

"In this case when you click on the WebDataTree the focus is transferred to it in order to process events. If the drop down is closed at this point, then interaction with a templated control inside the drop down is impossible. After this point the drop down does not have focus so if you click outside, blur would be triggered for the tree and not for the drop down, which would not make the drop down close. This behavior is expected, otherwise there is no way to handle events correctly for a templated control."

Please let me know if you have any questions.
