Baseline sample

[robert]

Hello, i have found a interesting sample (Baseline_WPF)  in the xaml-sdk-master file.
My problem is i need this solution for my Project but this is coded in VB.NET and i
can't translate the c# code correctly because there a lot of special features inside like
yield operations. Please can you help me to translate this sample to VB.NET.

Hello Robert,

We are happy to hear that our examples are helpful for your scenario.
I have converted the Baseline project to Visual Basic and attached it in this post.

Thank you for your help. I used the online telerik converter but
without success. What tool are you using or is recommended?

Hello Robert,

The Telerik Code Converter only converts code snippets. That is why for converting whole projects we use the Instant VB program, which has a free version and can be found here.

Hello Polya,

thank you for your tip. Now i have implemented the baseline and it works correctly. I have a last question. In addition to the baseline i want to draw 2 custom lines boundet to a date property defined as linedate1 and linedate2 in the custom gantttask. I have analyzed the deadline sample but without success to draw 2 lines and implement a second selector to the baseline selector. Is it possible to extend the baseline sample? It would be a great help für me. Thank you very much for your help.

Regards,
Robert

Hello Polya,

now i have integrated successfully the two selectors together. Now i try to show
a tooltip at a custom line (i.e. date) but without success.

My template:

<Style TargetType="base:TimeLineDeadlineContainer">
         <Setter Property="Canvas.ZIndex" Value="100"/>
         <Setter Property="BorderBrush" Value="DarkBlue"/>
         <Setter Property="BorderThickness" Value="2" />
         <Setter Property="Margin" Value="0 0 -3 0" />
         <Setter Property="ToolTipService.ToolTip" Value="{Binding OriginalEvent.TimeLineDeadlineEventInfo.LineDate1}"/>
         <Setter Property="Template">
             <Setter.Value>
                 <ControlTemplate TargetType="base:TimeLineDeadlineContainer">


                     <Rectangle Width="2" VerticalAlignment="Stretch" Fill="DarkBlue"  />
                     ....

The Tooltip dosn't show any data. How can i achieve to get and show the value as tooltip?

Regards,
Robert

Hello Robert,

I am happy to hear that you managed to get both examples working for you.

The issue with the missing tooltip content might be because the data context of the TimeLineDeadlineContainer is not set or is set to something unsuitable.

Referring to the Deadline example - if in the TimeLineDeadlineContainer.DataItem we also set the container DataContext to the passed TimeLineDeadlineEventInfo - we can access all the information from the TimeLineDeadlineEventInfo in the binding of the tooltip content.

So, for example, if we want to show the Deadline date in the tooltip of the TimeLineDeadlineContainer we should:

Public Property DataItem() As Object
    Get
        Return Me.data
    End Get
    Set(ByVal value As Object)
        If Me.data IsNot value Then
            Me.data = value
            Dim info = TryCast(Me.data, TimeLineDeadlineEventInfo)
            If info IsNot Nothing Then
                Me.Deadline = info.Deadline
                Me.IsExpired = info.IsExpired
                'Set the container DataContext to be the info.
                Me.DataContext = info
            End If
        End If
    End Set
End Property

<Style TargetType="local:TimeLineDeadlineContainer">
    <Setter Property="telerik:ZIndexManager.ZIndex" Value="100" />
    <Setter Property="Margin" Value="0 0 -4 0" />
    <Setter Property="Template">
        <Setter.Value>
            <ControlTemplate TargetType="local:TimeLineDeadlineContainer">
                ...
            </ControlTemplate>
        </Setter.Value>
    </Setter>
    <Setter Property="ToolTipService.ToolTip" Value="{Binding Deadline}"/>
</Style>

Hopefully this resolves the issue.
