    copied!<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>
