I have a GridView on my page with 3 columns, RightKey, AllowDeny, and Caption. AllowDeny is a checkbox. When Saved is clicked I
want to iterate through all rows and get these 3 values. So far I have:

foreach (GridViewRow Row in grdRights.Rows)
{
    CheckBox cb = (CheckBox)Row.FindControl("chkAllowDeny");
}

But the other 2 columnd are bound, and there's no public ID property. So how do I get the values of these two columns?

I'm sure it's something like

TextBox txt= (TextBox)Row.FindControl(-- name here --);   

But if I can't set the ID, then what's the name?

I also tried

string textBoxText = ((TextBox)Row.FindControl(Row.Controls[0].ID)).Text;

But it errors with "Object reference not set to an instance of an object"
