WPF customer control and direct content support
- by Mmarquee
I am fairly new to WPF, and am a bit stuck, so any help would be appreciated.
I am trying to write WPF custom control that encapsulates several elements of functionality that I already having working (i.e sorting, filtering, standard menus, etc.), but in a nice neat package to avoid repetition.
Anyway I have created the custom control (based on control), and then have the following in the Generic.Xaml
<ResourceDictionary
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:local="clr-namespace:Controls.ListViewExtended">
<Style TargetType="{x:Type local:ListViewExtended}">
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type local:ListViewExtended}">
<Border Background="{TemplateBinding Background}"
BorderBrush="{TemplateBinding BorderBrush}"
BorderThickness="{TemplateBinding BorderThickness}">
<ListView>
<ListView.View>
<GridView>
<!-- Content goes here -->
</GridView>
</ListView.View>
</ListView>
</Border>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
</ResourceDictionary>
When I try to add GridViewColumns (or any control really), as below ...
<elv:ListViewExtended>
<GridView>
<GridViewColumn Width="140" Header="Column 1" />
<GridViewColumn Width="140" Header="Column 2" />
<GridViewColumn Width="140" Header="Column 3" />
</GridView>
</elv:ListViewExtended>
I get the "... does not support direct content" error.
I have created a dependancy property (again below) that allows the adding of GridView, but it still doesn't work.
public static DependencyProperty GridViewProperty;
public static string GridViewHeader(DependencyObject target)
{
return (string)target.GetValue(GridViewProperty);
}
public static void GridViewHeader(DependencyObject target, string value)
{
target.SetValue(GridViewProperty, value);
}
Thanks in advance
