我們有通過綁定轉換器轉換陣列:自定義活動:WorkflowItemsPresenter不會顯示轉換陣列
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;
}
皈依效果很好,但它不是在我們的動態GUI
所示GUI代碼與綁定:
<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>
爲什麼是GUI不顯示爲列表???它沒有轉換器運作良好。 謝謝
希望將此標記爲工作流程基礎-4,但不知道如何... – 2010-02-26 07:07:50
