DataGrid InPlace Editing

[msnews.microsoft.com]

Hi
I wrote this code for InPalce Updating in DataGrid but Label1 shows previous
data not changed data.
Why it doesn't work correctly?
private void DataGrid1_UpdateCommand(object source,
System.Web.UI.WebControls.DataGridCommandEventArgs e)
{
//
Label1.Text = ((TextBox)e.Item.Cells[1].Controls[0]).Text ;
//....

Thanks
