[CLOSED] Multicombo with group and treeview
Hello,
We are trying to create multicombo with groups. To achive this we have embeded a tree control within combo box. UI is looking good but when we are trying to set the selected items text in combo textbox, the dropdown is getting closed. Below is the code snippet. Is there any property that can stop the dropdown from getting closed.
