Binding errors from custom popups

[tim]

I get the following binding errors in my output window.

Code: [Select]

System.Windows.Data Error: 40 : BindingExpression path error: 'ProposedStartTime' property not found on 'object' ''GanttChart' (Name='GanttChart')'. BindingExpression:Path=ProposedStartTime; DataItem='GanttChart' (Name='GanttChart'); target element is 'TextBlock' (Name='CustomMovingInfoPopup_ProposedStartTime'); target property is 'Text' (type 'String')
System.Windows.Data Error: 40 : BindingExpression path error: 'ProposedEndTime' property not found on 'object' ''GanttChart' (Name='GanttChart')'. BindingExpression:Path=ProposedEndTime; DataItem='GanttChart' (Name='GanttChart'); target element is 'TextBlock' (Name='CustomMovingInfoPopup_ProposedEndTime'); target property is 'Text' (type 'String')
System.Windows.Data Error: 40 : BindingExpression path error: 'ProposedDuration' property not found on 'object' ''GanttChart' (Name='GanttChart')'. BindingExpression:Path=ProposedDuration; DataItem='GanttChart' (Name='GanttChart'); target element is 'TextBlock' (Name='CustomResizeInfoPopup_ProposedDuration'); target property is 'Text' (type 'String')
System.Windows.Data Error: 40 : BindingExpression path error: 'ProposedStart' property not found on 'object' ''GanttChart' (Name='GanttChart')'. BindingExpression:Path=ProposedStart; DataItem='GanttChart' (Name='GanttChart'); target element is 'TextBlock' (Name='CustomResizeInfoPopup_ProposedStart'); target property is 'Text' (type 'String')
System.Windows.Data Error: 40 : BindingExpression path error: 'ProposedEnd' property not found on 'object' ''GanttChart' (Name='GanttChart')'. BindingExpression:Path=ProposedEnd; DataItem='GanttChart' (Name='GanttChart'); target element is 'TextBlock' (Name='CustomResizeInfoPopup_ProposedEnd'); target property is 'Text' (type 'String')

Both controls are created in GanttChart_TemplateApplied:

Code: [Select]

private void GanttChart_TemplateApplied(object sender, EventArgs e)
{
    FlexyGanttMain.GanttChart.MovingInfoPopup = new CustomMovingInfoPopup();
    FlexyGanttMain.GanttChart.ResizeInfoPopup = new CustomResizeInfoPopup();
}
They look like this:

Code: [Select]

<Popup x:Class="[...]CustomMovingInfoPopup"
             xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
             xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"

             xmlns:p="clr-namespace:[...]"
             mc:Ignorable="d"
            Placement="Relative"
       >
[...]
    <ContentControl Style="{StaticResource ResourceKey=ToolTipStylePopup}" MinWidth="125" Height="Auto">
        <Grid>
            <Grid.ColumnDefinitions>
                <ColumnDefinition Width="Auto"/>
                <ColumnDefinition Width="*"/>
            </Grid.ColumnDefinitions>
            <Grid.RowDefinitions>
                <RowDefinition />
                <RowDefinition />
            </Grid.RowDefinitions>
            <TextBlock Name="CustomMovingInfoPopup_Start" Text="{p:Resources Name=Start}" HorizontalAlignment="Left" FontWeight="Bold" Margin="0,0,5,0"/>
            <TextBlock Name="CustomMovingInfoPopup_ProposedStartTime" Grid.Column="1" HorizontalAlignment="Right" Margin="0, 0, 0, 10" Text="{Binding ProposedStartTime, StringFormat=g}" />

            <TextBlock Name="CustomMovingInfoPopup_End" Grid.Row="1" Text="{p:Resources Name=End}" HorizontalAlignment="Left" FontWeight="Bold" Margin="0,0,5,0"/>
            <TextBlock Name="CustomMovingInfoPopup_ProposedEndTime" Grid.Row="1" Grid.Column="1" HorizontalAlignment="Right" Margin="0, 0, 0, 10" Text="{Binding ProposedEndTime, StringFormat=g}" />
        </Grid>
    </ContentControl>
</Popup>
However when moving a task in gantt the properties are evaluated correctly inside the popup. I guess that on startup the data context of the popup controls still might be set to GanttChart and only later is changed to FlexyTaskResizeTracker.

Could you please take a look into this, so we can avoid those binding errors?

Thanks!
