server crashes when I access a certain control

Discussion in 'ASP .Net' started by Boban Dragojlovic, Jul 28, 2003.

  1. I have the following control defined (among others) ... it represents the
    active form on the ASP

    Protected WithEvents frmMain As System.Web.UI.HtmlControls.HtmlForm

    Then I have this

    Private Sub Page_Load(ByVal sender As System.Object, ByVal e As
    System.EventArgs) Handles MyBase.Load

    If Page.IsPostBack Then
    For Each ctl As WebControl In Me.frmMain.Controls
    If ctl.CssClass = "FieldInError" Then
    ctl.CssClass = ""
    End If
    End If

    End Sub

    The "for each" loop is just designed to clear up any "highlighting" I may
    have done during a previous round trip.

    When this code is executed, the 'for each ....' statement crashes ASP.NET

    The error in the Application Log says that it was recycled because it sucked
    up too much memory. I watched it. It goes from 30k to 360k within a couple
    of seconds.

    I stepped through this code, and it never gets to the 'if ctl.cssClass'
    statement ... it dies on the 'for each' statement.

    Any ideas?

  2. Most of the controls in the Controls collection are not going to be
    WebControl so it would bomb. Get them as Control and then test for children
    and is it a WebControl. You will have to step into the children to get the
    controls say...under the HtmlForm control.
