Create a ComboBox/DropDown in a ToolbarControl

FergusGraham — Thu, 19 Mar 2015 00:04:42 GMT

I am stuck.... I am developing an ArcEngine MapControl application and I want to add a combobox to the toolbarcontrol. Something I assumed should be relatively straightforward. I have tried developing a custom control that implements ICommand and I've tried creating a BaseCommand that implements IComboBox. I just can't seem to hook it all up so that it displays anything but the Command button. Any pointers or samples would be appreciated.

I think what you are after is an IToolControl. See the documentation here:

IToolControl Interface

Yes.... that was it exactly. Thanks.

Create a BaseCommand

Implement IToolControl

Instantiate a ComboBox in the BaseCommand.New()

Add hWnd = ComboBox.Handle.ToInt32 in the Get of the IToolControl.hWnd property
