I'm using component dropdownbutton to display a treeview, but I have a problem.
Using the mouse to click on dropdownbutton, the method is triggered automatically dropdown, then showing the treeview. When the keyboard focus is the method dropdown is not fired, not showing the treeview.
In the event "ENTER" of dropdownbutton, I put the method dropdown over the reverse happens when the focus is triggered by clicking the treeview is not showing, and when the focus is driven by the keyboard appears to treeview.

Hi,

I don't think I have any samples of this in VB. But there's really not much to it. You use the ButtonsRight collection of the combo to add a DropDownEditorButton. Then you assign a Control to the button - it can be any control you want.

You will have to handle some events of the combo such as EditorButtonDropDown in order to set up the control that is acting as the list. For example, when you drop it down, you probably want to highlight the item that matches the current value.

And you will also want to handle some events of whatever control you are using as the list. For example, when the used clicks on a node in the tree (or a row in the grid, depending on what you decide to use), you will need to close the dropdown and update the combo's Value.

You can send me something in vb.
I want to study the situation to implement something.
