As a side note, you can write chk.Checked = (cellText == "1"); without losing any readability.

NB: Your nested loops aren't doing what you think they're doing. To be honest, I'm struggling to understand what you think they're doing; but whatever it is, they're not doing it.

You can effectively replace the code with:

if (e.Row.RowType == DataControlRowType.DataRow)
{
    string cellText = dt.Rows[dt.Rows.Count - 1][2].ToString();
    bool isChecked = cellText == "1";
    
    foreach (GridViewRow row in gdvUserDetails.Rows)
    {
        CheckBox chk = (CheckBox)row.Cells[0].FindControl("chkRow");
        chk.Checked = isChecked;
    }
}

There isn't really anything much we can do to help you - it depends so much on your data as to what happens. That's some odd code though ... I see no real point in the nested loops, given that the result of the inner loop will be the same each time ...

So, it's going to be up to you.
Fortunately, you have a tool available to you which will help you find out what is going on: the debugger. If you don't know how to use it then a quick Google for "Visual Studio debugger" should give you the info you need.

Put a breakpoint on the first line in the function, and run your code through the debugger. Then look at your code, and at your data and work out what should happen manually. Then single step each line checking that what you expected to happen is exactly what did. When it isn't, that's when you have a problem, and you can back-track (or run it again and look more closely) to find out why.

Sorry, but we can't do that for you - time for you to learn a new (and very, very useful) skill: debugging!

Solution 2

Accordingly to your code:

C#

string cellText = dt.Rows[i][2].ToString();
CheckBox chk = (CheckBox)row.Cells[0].FindControl("chkRow");
if (cellText == "1")
{
    chk.Checked = true;
}
else
{
    chk.Checked = false;
}

Probably... in last row cellText variable does not hold "1"...
