Im getting menuItem icon appearing only on last menuItem. If i snoop the app only last menuItem has image in icon, while if i debug all MenuItems appear to have image in icon. Also if i add submenuItem the icon on menuItem dissapears once i open submenus and the last submenu gets the icon... Any idea? PS: also tooltips on menu item dont work. Im using caliburn micro and fluent ribbon controls.
<ControlTemplate x:Key="dropDownButton">
<ef:DropDownButton Header="{Binding DisplayName}"
ItemsSource="{Binding Items}"
LargeIcon="{Binding LargeIconPath}"
cm:Message.Attach="ClickAction()"
ef:KeyTip.Keys="{Binding KeyTip}">
<ef:DropDownButton.ItemContainerStyle>
<Style TargetType="MenuItem">
<Setter Property="Header"
Value="{Binding DisplayName}"/>
<Setter Property="Icon">
<Setter.Value>
<Image Source="{Binding Path=IconPath}"/>
</Setter.Value>
</Setter>
<Setter Property="ItemsSource"
Value="{Binding Items}"/>
<Setter Property="cm:Message.Attach"
Value="ClickAction()"/>
<Setter Property="ef:KeyTip.Keys"
Value="{Binding KeyTip}"/>
<Setter Property="ToolTip">
<Setter.Value>
<ef:ScreenTip Title="{Binding DisplayName}"
HelpTopic="ScreenTip help ..."
Image="{Binding LargeIconPath}"
Text="Text for ScreenTip"/>
</Setter.Value>
</Setter>
</Style>
</ef:DropDownButton.ItemContainerStyle>
<ef:DropDownButton.ToolTip>
<ef:ScreenTip Title="{Binding DisplayName}"
HelpTopic="ScreenTip help ..."
Image="{Binding LargeIconPath}"
Text="Text for ScreenTip"/>
</ef:DropDownButton.ToolTip>
</ef:DropDownButton>
You are setting Icon property to an Image control in Style. Now, only one copy of Style is created and thus, only one copy of Image is created. Now, any control can have only one parent at a time. So, when it is assigned to last MenuItem, it is removed from previous MenuItem controls. To fix this, use Templates.
Instead of setting Header property, set HeaderTemplate:
<Setter Property="HeaderTemplate">
<Setter.Value>
<DataTemplate>
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="Auto" />
<ColumnDefinition Width="*" />
</Grid.ColumnDefinitions>
<Image Grid.Column="0"
Source="{Binding Path=IconPath}" />
<TextBlock Grid.Column="1"
Text="{Binding DisplayName}" />
</Grid>
</DataTemplate>
</Setter.Value>
</Setter>
I'm not sure of what properties are exposed by the control toolkit you are using. But, I'm sure they must have a template property.
After doing this, you don't need to set Icon property in style.
