Gridview strangeness

[Guest]

Is there any reason why in the following code the text value of the cells for
the row that is being updated is always without fail blank ? All the other
rows in the grid view show the data that they have in them. What ever row has
been edited however shows blanks, even though the data is displaying in the
gridview.

protected void GridView1_RowUpdating(object sender, GridViewUpdateEventArgs
e)
{
for (int x = 0; x < GridView1.Rows.Count; x++)
{
string val = GridView1.Rows[x].Cells[0].Text + " " +
GridView1.Rows[x].Cells[1].Text + " " +
GridView1.Rows[x].Cells[2].Text + " " +
GridView1.Rows[x].Cells[3].Text + " " +
GridView1.Rows[x].Cells[4].Text;

Response.Write(val);
Response.Write("<br>");
}
