Typing in ALL CAPS means SHOUTING in the web world. Kindly, edit and update your question lowering the tone.

BTW. is it a repost? Sounds like, I have read it some time back...

Could you change the caps to normal form, else you may not get an answer

Sorry guys ,

if you could show us the code how you are populating the gridview at the first submit then there are more chances identify the exact issue. Wrong guesses may be costlier.

I took a object name User and 2 property userId,userName
my code
in button click
User user=new User();
user.UserId=TextBox1.Text;
user.UserName=TextBox2.Text;

IList lst=new ArrayList();
lst.add(user);

GridView1.DataSource=lst;
GridView1.DataBind();

Solution 1

IList lst=new ArrayList();

The above line is why it is replacing your first submit value.

You are recreating the entire list, and then giving it the only value of the new user you submitted.

Make the lst field a class member, then do this:

if( lst == null )
{
   lst = new ArrayList();
}

lst.add(user); 
GridView1.DataSource=lst; 
GridView1.DataBind();

you should store your objects in session and later on rebind it on your gridview whenever you redirect to pages.
