Verify GridView item is selected 1

[lance59]

Looking to verify that any item or row in gridview is selected before moving to the next page.

If GridView1.?????????? = True Then
Dim S2 As String = Server.UrlEncode(u)
Response.Redirect("Registration.aspx?class_Reg1=" & S2)
Else
Response.Write("<font color=""Red""><i> Please select at least one row </i> </font>")
End If

TIA

Use the SelectedIndex property to determine if a row is selected. From MSDN:

"The zero-based index of the selected row in a GridView control. The default is -1, which indicates that no row is currently selected."

So:

If GridView1.SelectedIndex > -1 Then
Dim S2 As String = Server.UrlEncode(u)
Response.Redirect("Registration.aspx?class_Reg1=" & S2)
Else
Response.Write("<font color=""Red""><i> Please select at least one row </i> </font>")
End If
