It is possible to set the ToolCaptionButtons
property at desgin-time. Just select the a ToolWindow from the designer and choose the desired option from the property grid. However, please note that you can choose only one of the predefined options, but not a combination of them.
As to your feedback Cyril. T, you are correct. Currently, we have an issue with setting the ToolCaptionButtons property when the DockWindow is a HostWindow. We will address this issue in one of our next releases. For the time begin, please first add a ToolWindow using the DockWindow method and then load the desired content. I am updating your Telerik points for the report.
