How to show tooptip of tool window header?

Hello,

Thanks for the question. At the moment, the Docking/MDI product doesn’t include a built‑in option for displaying a tooltip on a tool window container's title bar. While it’s technically possible to retemplate the ToolWindowContainer control to insert your own tooltip logic, we generally don’t recommend going that route unless absolutely necessary. The container template is fairly involved, and replacing it tends to require a significant amount of work to maintain parity with the default appearance and behavior

A more practical workaround is to take advantage of the customization points we already expose. The "Custom Title Bar Content" QuickStart shows how you can inject your own UI elements into the title bar. That approach would let you:

• Display the information directly in the title bar.
• Add an element that has its own tooltip.
• Provide a small button or icon the user can click to see more detail.

This recommended workaround keeps you within the supported customization model and avoids the complexity of retemplating the entire container.
