How to fill the client area when the main form is resized after the RadDock control LoadFromXml

[yw]

I am testing the RadDock control (2025 Q2 version).
The Dock property of dock is set to Fill.
After applying the layout with dock.LoadFromXml(xmlPath, clearDocking: false);, when the MDI main form is resized, the laid-out window does not fill the client area (as indicated by the red arrow in the figure). How can I modify it so that the laid-out window fills the client area of the MDI window?

Hello,

Based on the picture only, I can not determine why the window doesn’t fill the client area. Could you please provide the saved XML file so that I can load it on my side and try to reproduce the issue?

If possible, please share the entire project. That way, I can examine it more closely and provide more accurate assistance. Thank you in advance for your understanding. 

Looking forward to your reply.

This is the form constructor：

 public TwMessageOutput() { }

public TwMessageOutput(IEventBus bus)

 public DocDefenseOutline() { }
 public DocDefenseOutline(IEventBus bus)

 

public RadFrmMain(IEventBus bus,...）{...}

Hello, 

I used the provided xml in a sample project but I am still not able to replicate the exact problem on my side. This is why I provide my test project for your reference. Please try to replicate the exact behavior there and get the project back to me. Without having a project that can replicate the problem, it is difficult to determine what exactly happens.

You can find my sample project, also including your xml, attached to this message.

Looking forward to your reply.
