I want to give option to user to mention all config level data on UI at the time of setup installation.By referring no of sites I am able to achieve that expected output, but there are some moification.I am able to show label and text box and bind that value by referring some below link.Customize User Interfaces and Pass User Input to Installer Classes[^]ScottGu's Blog - Tip/Trick: Creating Packaged ASP.NET Setup Programs with VS 2005[^]Expection is:1)I want to do validation means user will be not able to click on next button by keeping empty text box.2)Now user mentioning data into text box normally, instead of that I want to give browse button to select path and fill text box.What I have tried:This is code that I am using for showing and binding text box value.
