How can I select a particular cell value in a grid view control?

How can I select a particular cell value in a grid view control to store in another variable (a string).

I created an empty row in my GridView and I entered blank values into that row.

How can I update the DB table from the GridView now?

From stackoverflow

• foreach(GridViewRow row in this.urgridname.Rows)
  {
  var a=row.Cells[1].Text
  }
  

  Gets a GridView row's cell value.
