How to remove the border of RadFrom

Hello, Kumaran,

You can set the Visibility property of the RadFormElement.ImageBorder to ElementVisibility.Collapsed in the constructor of the form.

this.FormElement.ImageBorder.Visibility = ElementVisibility.Collapsed;

Here is the result on my side. I am setting the background and border colors of the form, so we can see clearly the inner(image) border bounds.


Here is the result with no custom colors applied:

More information about the image border of RadForm is available here: https://docs.telerik.com/devtools/winforms/controls/forms-and-dialogs/form/using-the-formimageborderprimitive

Have in mind that the resize cursor of the form appears only when the mouse is over the border. If you change the border from 4,1,4,4 to 1,1,1,1 by collapsing the image border it will quite be a bit harder to resize the form.

I hope this will help. Let me know if you need further assistance.

Todor Vyagov
