Hello Mahdi,

If you use the RadRibbonView for WinUI, you can set the ContentHeight property of the control. However, from the picture it looks like you are using RadRibbonBar for WinForms. If this is the case, then you can set a fixed size of one of the RadRibbonBarGroup elements. This will auto-size the content area of the selected tab. For example:

this.radRibbonBarGroup1.AutoSize = false;
this.radRibbonBarGroup1.Size = new Size(300, 300);

You can also check the following forum.

If you have any questions related to WinForms, please open a new forum in the UI for WinForms forums section.

Regards,
Martin Ivanov
