Hello, a question, how did you open a dockable window from a toolbar? I have a solution Visual.NET with tools already created, try to add a dockable toolbar window, but I fail to operate, this is not an Add-In. Please Help me!!
Please take a look at the Creating dockable windows help topic. This topic describes three ways to implement a custom dockable window: using add-ins, extending ArcObjects by manually implementing Component Object Model (COM) interfaces, and using the Dockable Window template in the ArcObjects .NET Software Development Kit (SDK).
Under this topic you will also see a couple of samples that demonstrate the use of these.
