I was using a bootstrap modal to 2 different forms in Single aspx page. Here the Problem was there was 2 forms so obviously 2 buttons are there, and i have used asp validation also so there was a conflict between the 2 buttons to validate and submit the form.
When i click Button1 it was validating the other buttons text field also. so to overcome from that use i got a solution From “ValidationGroup” Keyword, add this to all the asp input fields and button, group them as given below.
By using ValidationGroup You have to Group the Text fields.
