Selected Task problem when using Originalvent

[Prolay]

Hi

When I am using "OriginalEvent" to display a column by setting the column's cell template. The column is rendered properly but when the task is selected the text of the column goes blank. I have attached a screenshot.

<telerik:ColumnDefinition MemberBinding="{Binding EstimatedHours,Converter={StaticResource DurationConverter}, ConverterParameter=D}" Header="Est Hrs" ColumnWidth="50">
    <telerik:ColumnDefinition.CellTemplate>
        <DataTemplate>
            <TextBlock TextAlignment="Right" VerticalAlignment="Center" Text="{Binding OriginalEvent.EstimatedHours,Converter={StaticResource DurationConverter}, ConverterParameter=D}"/>
        </DataTemplate>
    </telerik:ColumnDefinition.CellTemplate>
    <telerik:ColumnDefinition.CellEditTemplate>
        <DataTemplate>
            <telerik:RadMaskedTextBox x:Name="txtEstimatedHrs" Value="{Binding EstimatedHours,Mode=TwoWay}" Mask="n" MaskType="Numeric" />
        </DataTemplate>
    </telerik:ColumnDefinition.CellEditTemplate>
</telerik:ColumnDefinition>

Hello Prolay,

I tried the scenario you described, but I couldn't reproduce the problem. Could you please check the attached project and let me know if I'm missing something?

I also demonstrated a second approach that will let you align your cells to the right, but with a little better performance than using the OriginalEvent property - using MemberBinding combined with the FormattedValue.

Hi Miroslav,

When I searched a bit. the problem is because of this particular style. For time being I have commented out this code. Can you help me in understanding the problem with this style.

<Style x:Key="SimpleCellContainerStyle" TargetType="Control">
    <Setter Property="MinHeight" Value="24" />
    <Setter Property="gantt:TreeCellContainer.LevelOffset" Value="15" />
    <Setter Property="BorderThickness" Value="1" />
    <Setter Property="Padding" Value="5 0" />
    <Setter Property="scheduling:ZIndexManager.ZIndex" Value="30" />
    <Setter Property="VerticalContentAlignment" Value="Center" />
    <Setter Property="HorizontalContentAlignment" Value="Stretch" />
    <Setter Property="Template">
        <Setter.Value>
            <ControlTemplate TargetType="Control">
                <TextBlock Margin="{TemplateBinding Padding}" HorizontalAlignment="{TemplateBinding HorizontalContentAlignment}"
                        VerticalAlignment="{TemplateBinding VerticalContentAlignment}" x:Name="ValueTextBlock" />
            </ControlTemplate>
        </Setter.Value>
    </Setter>
</Style>

Thanks and Regards,
Prolay

Hello Prolay,

The style you sent seems correct to me and I cannot tell what goes wrong with it.
