Hi George616,
To clear a Label set the Text property to an empty string.
Same way to clear GridView set the DataSource property yo null.
Create a method like below and call when ever required.
C#
private void ClearControl()
{
GridView1.DataSource = null;
GridView1.DataBind();
Label1.Text = "";
Label2.Text = "";
}
VB.Net
Private Sub ClearControl()
GridView1.DataSource = Nothing
GridView1.DataBind()
Label1.Text = ""
Label2.Text = ""
End Sub
