devexpress

I installed DevExpress on my PC, now I need to add its elements to the elements panel, which I can't do. I couldn't find a so ... n the Internet, so I decided to ask the question myself. How do I add DevExpress controls to the Visual Studio Control Panel?

I am implementing a regex to accept IP address, for this I am using a mask in the textEdit component of DevExpress, but when ... leave the field blank or with only a part filled locks all other form controls. Regex used: ([0-9]{1,3}\.){3}[0-9]{1,3}
