    <p>I've been struggling with this for a while now and I really can't find a solution. I've checked all the standard memory leak issues i.e. PageActivity, DataTemplates etc. and it's nothing like that. I am using windbg and with !GCRoot I get:</p> <blockquote> <p>DOMAIN(097C9970):HANDLE(Pinned):52412f8:Root: 0ade4260(System.Object[])-><br> 09deab28(System.Collections.Generic.List`1[[System.Object, mscorlib]])-><br> 0a3a8708(System.Object[])-><br> 0a42becc(System.Windows.Shapes.Rectangle)-><br> 0a4267e4(System.Windows.Controls.Grid)-><br> 0a40da84(System.Windows.Controls.Primitives.CalendarDayButton)-><br> 0a3cc8e8(System.Windows.Controls.Calendar)-><br> 0a3ccd44(System.Windows.Input.MouseButtonEventHandler)-><br> 0a3cc828(System.Windows.Controls.DatePicker)-><br> 0a3cd594(System.Windows.Controls.StackPanel)-><br> 0a3cd690(System.Windows.Controls.StackPanel)-><br> 0a3cfcd0(System.Windows.Controls.StackPanel)-><br> 0a3cfdcc(System.Windows.Controls.Border)-><br> 0a3e11f0(System.Windows.Controls.ContentPresenter)-><br> 0a3e00d0(System.Windows.Controls.ContentControl)-><br> 0a3dffd4(System.Windows.Controls.Grid)-><br> 0a3e02d0(System.Windows.Controls.Border)-><br> 0a3de464(System.Windows.Controls.Grid)-><br> 0a3cc160(System.Windows.Controls.Expander)-><br> 0a3cc0b8(System.Windows.Controls.StackPanel)-><br> 0a3d4078(System.Windows.Controls.Grid)-><br> 0a3d4174(System.Windows.Controls.StackPanel)-><br> 0a3d4f90(System.Windows.Controls.ContentPresenter)-><br> 0a3d6398(System.Windows.Controls.ContentPresenter)-><br> 0a3d4ff4(System.Windows.Controls.ContentControl)-><br> 0a3d51e4(System.Windows.Controls.Grid)-><br> 0a3cadd4(System.Windows.Controls.Activity)-><br> 0a3caa4c(System.Windows.Controls.Grid)-><br> 0a3ca310(EMSOLG.Registration.StudentPayDetails)</p> </blockquote> <p>Is there any way I can find out with more detail where is the leak?</p> <p>It happens when I change the selected value of the combobox</p> <pre><code>&lt;ComboBox x:Name="cmbPaymentMethod" Height="23" Background="LightYellow" DisplayMemberPath="Value" SelectedValuePath="Key" SelectedValue="{Binding intPaymentMethod,Mode=TwoWay}" SelectionChanged="cmbPaymentMethod_SelectionChanged" /&gt; </code></pre> <p>The Code behing for the event is:</p> <pre><code>PageActivity.IsActive = true; tblAppForm thisApplication = (tblAppForm)this.DataContext; thisApplication.curInvoiceAmount = 0; RG.Amount = ; thisApplication.curRecovery = 0; txtInvoiceTotal.Text = "0.00"; </code></pre> <p>When the control is unloaded I've tried setting the <code>DataContext = null;</code> as well as a host of other controls and variables that I thought might cause the leak</p>

    1. COJust my 2 cents but have you looked into VS2010 SP1, its in Beta but its supposed to have a silverlight profiler? (Its called Performance Wizard) http://rabeb.wordpress.com/2010/12/18/new-feature-for-silverlight-in-visual-studio-2010-service-pack-1/

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
