WPF Databinding to Custom Collection Objects

Question

Public Sub New(ByVal log As Entities.LogSystem)
    InitializeComponent()   
    Me.DataContext = log
End Sub

This is the the initializer for my custom control It passes in a single entity that has several property fields. This control is added to a parent control so that it appears in a stackpanel.

Anyway I am trying to get the specific data from this control into several different text boxes:

<UserControl x:Class="LogSystemPickerItem"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    xmlns:local="clr-namespace:WavelengthIS.WISRED.UserControls"
    Width="579" Height="122">
    <UserControl.Resources>
        <local:LogSystemPickerItem x:Key="Log"/>
    </UserControl.Resources>

    <Grid DataContext="{Binding Source={StaticResource Log}}">
        <Label Height="30" Name="Label1" VerticalAlignment="Top" Content="{Binding deptDescription}"/>

    </Grid>
</UserControl>

As you can see i havent really gotten too far. I have tried many different ways to do this including using dependency properties...I just really cant find a tutorial that shows this specific circumstance...can anyone point me in the right direction?

Answer 1

If you're setting the DataContext in the code behind as per your first code snippet, there's no need to also do it in the XAML, so you can remove the "Log" resource and the corresponding DataContext assignment on the Grid.

Once you've done that, it should work assuming there is a deptDescription property on your log class.

... and in XAML you may do it this way...

<UserControl.DataContext>
    <local:LogSystemPickerItem/>
</UserControl.DataContext>
