or try like
protected void GridView1_RowCommand(object sender, System.Web.UI.WebControls.GridViewCommandEventArgs e)
  {
       if (e.CommandName=="MyCommand")
       {
            int row = int.Parse(e.CommandArgument.ToString());
            var cellText= gvOwner.Rows[row].Cells[1].Text.Trim();
       }
  }

Fine Subin.

Pass the grid view value as arguments to get value in another function

Hellow Subin,

Try below code

// Get the currently selected row using the SelectedRow property.

GridViewRow row = GridView1.SelectedRow;

// And you respective cell's value

TextBox1.Text = row.Cells[1].Text

And, are you tring to get data in another function?. if it so, please pass the gridview row as arguments and use the value.
