Custom activity in WF 4.0: WorkflowItemsPresenter wont show converted array
- by lotusnote
Hi There,
we have an Array which is converted via a Binded Converter:
else if (TTools.IsOfBaseClass(value.GetType(), typeof(System.Activities.Presentation.Model.ModelItemCollection)))
{
OurBaseClass[] test = (value as ModelItemCollection).GetCurrentValue() as OurBaseClass[];
List<OurBaseClass> listOfArray = new List<OurBaseClass>();
foreach (OurBaseClass item in test)
{
listOfArray.Add(item);
}
return listOfArray;
}
the convertion works well but it is not shown in our dynamically gui
gui code with bindings:
<sap:WorkflowItemsPresenter xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:sap="clr-namespace:System.Activities.Presentation;assembly=System.Activities.Presentation" Grid.Column="0" Name="MyArray" Items="{Binding Path=ModelItem.MyArray}" MinWidth="150" Margin="0">
<sap:WorkflowItemsPresenter.SpacerTemplate >
<DataTemplate>
<TextBlock Foreground="DarkGray" Margin="30">..</TextBlock>
</DataTemplate>
</sap:WorkflowItemsPresenter.SpacerTemplate>
<sap:WorkflowItemsPresenter.ItemsPanel>
<ItemsPanelTemplate>
<StackPanel Orientation="Vertical" HorizontalAlignment="Center" Margin="0"/>
</ItemsPanelTemplate>
</sap:WorkflowItemsPresenter.ItemsPanel>
</sap:WorkflowItemsPresenter>
Why is the gui not shown as a List??? it works well without converter.
Thanks
