Hi Kevin, I think you have to associate by providing the foreign key in the relationship.

Property(c => c.Company).IsRequired().WithMany()
.HasForeignKey(u => u.CompanyId);

Hi Kevin, check in Trigger whether Button's IsMouseOver is true and set the property Content with the following values.

<ControlTemplate.Triggers>
<Trigger Property="Button.IsMouseOver" Value="True">
<Setter TargetName="ButtonImage" Property="Content"/> <Setter.Value>
<StackPanel>
<Image>
<Image.Source>
<BitmapImage UriSource="{Binding RelativeSource={RelativeSource Self}, Path=MouseOverImageSource}" />
</Image.Source>
</Image>
</StackPanel>
<Setter.Value/>
</Trigger>
</ControlTemplate.Triggers>

I am not aware of Zune, however, I think you can use a Menu control and set its source to a collection ObservableCollection MenuItems. interface IMenuItem { string Caption; Visibility MenuVisibility; ICommand Command;} Bind the above properties in the MenuItem's ItemTemplate or HiearchicalTemplate. Apply DataTrigger on the MenuVisibility property to set visibility. Also you can customize the default menuitem's template style and modify the template as per your requirement. Please refer the below link which will give an idea on how to use the menu item template. http://msdn.microsoft.com/en-us/library/ms752296%28v=vs.85%29[^] http://msdn.microsoft.com/en-us/library/ms747082%28v=vs.85%29.aspx[^]

Hi Murugavel, I think you should be using background thread to do spell checks to overcome UI unresponsiveness. Execute your spellcheck call this.NHunspellTextBoxExtender1.SetSpellCheckEnabled(this.TextEditor, false); in a different thread. http://msdn.microsoft.com/en-us/library/cc221403%28v=vs.95%29.aspx[^]

Hi SelvaKathir, I assume you have implemented the following things for triggering the Error. 1. Viewmodel implements IDataErrorInfo interface. 2. Set ValidationAttribute on each property which has to be validated or Use SelfValidation attribute on the class and override DoValidate. 3. Controls in Xaml are using bindings and ValidatesOnDataErrors=true,NotifyOnValidationError=true 4. Use a textblock to display the error by binding the error content of the target field. "

Hi Santy, WPFToolKit provides charting control which is pretty simple to implement. Check the following article in codeproject WPF Toolkit Charting Controls[WPF Toolkit Charting Controls ]

Hi Kevin, Just updating the source won't work. You have to update the Button Content. for ex: <BitmapImage UriSource="{Binding RelativeSource={RelativeSource Self}, Path=MouseOverImageSource}" />

<ControlTemplate.Triggers>
<Trigger Property="Button.IsMouseOver" Value="True">
<Setter TargetName="ButtonImage" Property="Content"/> <Setter.Value>
<StackPanel>
<BitmapImage UriSource="{Binding RelativeSource={RelativeSource Self}, Path=MouseOverImageSource}" />

<Setter.Value/>
</Trigger>
</ControlTemplate.Triggers>

I think this should work..
