Winform maximized aunder the application bar

[Andrea De Luca]

Hi, i've dicovered a bug, or a strange behavior.
In a multi monitor Pc if a sfform is maximizd in the monitor with the application bar locked on the left the form is expanded to all the extension of the window. So the maximize and close button go under the application bar. 
If you move the application bar the maximize and minimize button are not visible.
Is there any solution?

Thank You very much

Andrea De Luca,

We are currently setting up a multi-monitor environment to verify the scenario you reported. In the meantime, could you please provide the following details to help us proceed:

Multi-monitor configuration

1.How many monitors are connected to the same machine?

2.What are the resolutions and scaling (DPI) values for each monitor (e.g., 100%, 150%)?

3.Which monitor is set as the primary display?

Sample confirmation

1.We have shared a sample for your reference. Can you confirm whether the same issue occurs with our sample?

2.In your screenshot, the title bar appears to be customized. please share the relevant details or code snippet.

Issue clarification

1. When you say “SfForm is maximized on a monitor with the application bar (taskbar) locked on the left, the form expands to the full window area,” do you mean when you maximize the SfForm on a monitor where the Windows taskbar is on the left side, does the window go behind the taskbar so the minimize, maximize, and close buttons are hidden?

Replication steps

1.Please provide the exact steps to reproduce the issue. Does it occur on initial application loading, or only after dragging the window from one monitor to another? If possible, please share a video demonstrating the problem.

Thank you for your assistance. This information will help us reproduce the issue and provide a fix or workaround.

Hi Andrea De Luca,

Thank you for providing the video. 

Currently, we are in the process of setting up Windows 10 with dual monitors. We need some time to validate the setup. We will provide an update once the environment is ready.

Andrea De Luca,

We have reviewed the reported issue on our end and confirmed it as a defect. And We have logged a bug, and we will provide feedback on October 14, 2025.

Temporary workaround:

In the meantime, as a temporary workaround, you can enable the maximize button for SfForm. When enabling the MaximizeBox, the SfForm window resizes properly, and all the icons are clearly visible within the window.

Code snippet to enable the MaximizeBox:

Me.MaximizeBox = True

Andrea De Luca,

We would like to let you know that Essential Studio Weekly NuGet packages (v31.2.4) has been published in nuget.org with the fix for the issue “SfForm does not resize properly when Windows10 taskbar is docked right and MaximizeBox is disabled”. Please let us know if you have any concerns in this.

 

 

Root cause analysis:

 

The SfForm incorrectly applies maximized window region logic even when MaximizeBox = false, causing layout clipping when the Windows 10 taskbar is docked to the right.
