Hi Ray,

Thank you for contacting Syncfusion Support.

We have prepared custom sample to meet your requirement. In this sample we have modified the control template of ComboBoxAdv to add TreeViewAdv as a child of it and we binded the TreeViewAdv’ s SelectedItem to ComboBoxAdv’ s content. Please find the sample from the below attachment.

Please let us know whether the below sample meets your requirements or not.

Hi Ray,
We have modified our last updated sample to close the Dropdown when selected item gets changed in TreeViewAdv. In this sample, we have changed the ComboBoxAdv’ s IsDropDownOpen property in SelectedItem changed event of TreeViewAdv. Please find the sample from the following location
Sample:ComboBoxTreeView

Thanks a lot .Can i set the item "Item 1.3.1" in your demo by default ?

Hi Ray,

We have modified our last updated sample. In this sample, we set the Item 1.3.1 as selected by default by binding its IsSelected property. But this selection gets updated in ComboBoxAdv once the dropdown popup gets open. The same behavior exist in MS ComboBox. Please find the sample from the below location
