I know what you mean. I used to adjust it in this property bar. Although the design window seems to be effective after adjusting in the property bar, the debugging operation is still not effective. You can try it. I don't know this. Is it a bug?

Hello,  

You can customize the controls at design time either via the Edit UI Elements in the Smart Tag or in the Properties section in Visual Studio. Usually, the changes are applied immediately after you save the changes. If you are experiencing any undesired behavior, it would be greatly appreciated if you can specify the exact steps how to replicate the problem you are facing. Thus, we would be able to investigate the precise case and determine whether it is an issue or not.

Hello, you can see from the picture I uploaded, I modified the padding of the window in the property bar. At this time we saw that the design window is in effect, but when I debugged, I found that the window is still There is no difference before. I tried to change the padding with code. There is no problem, but the adjustment in the property bar does not work. I hope you can help me, thank you very much.

Hello,   

According to the provided screenshots, it seems that you manipulate the Padding of the RadForm >> FormElement >> TitleBar in the Properties section. This is not serialized in the designer file. That is why when you run the application, these changes are not applied. Indeed, the recommended approach for such changes is to do them via code. However, it should work appropriately.
