我知道我在做什么很奇怪,但我希望它能够工作。我感觉有些不对劲。
我的资源中定义了一个 DataTemplate,如下所示:
<UserControl.Resources>
<ResourceDictionary>
<ResourceDictionary.MergedDictionaries>
<ResourceDictionary Source="../ParameterEditorResourceDictionary.xaml"></ResourceDictionary>
<ResourceDictionary>
<DataTemplate x:Key="ParameterDefault">
<StackPanel Orientation="Horizontal">
<TextBlock Text="("></TextBlock>
<ItemsControl ItemsSource="{//I need to set from code}">
//some code here
</ItemsControl>
<TextBlock Text=")"></TextBlock>
</StackPanel>
</DataTemplate>
</ResourceDictionary>
</ResourceDictionary.MergedDictionaries>
</ResourceDictionary>
</UserControl.Resources>
我在我的 xaml 中定义了一个 DataGrid,它有一个加载的事件。
<cc:PEDataGrid AutoGenerateColumns="False"
Loaded="CommonPEGrid_Loaded">
</cc:PEDataGrid>
在我的事件处理程序代码中,我想设置在我的 DataTemplate 中定义的 ItemsControl 的 ItemsSource。我背后的代码如下所示:
private void CommonPEGrid_Loaded(object sender, RoutedEventArgs e)
{
int i = 0;
DataGrid dg = sender as DataGrid;
DataGridTemplateColumn column = null;
//ParametersAllLoops is a ObservableCollection
foreach (ParameterLoop obj in ParametersAllLoops)
{
column = new DataGridTemplateColumn();
column.Header = "Loop ( " + i.ToString() + " )";
DataTemplate dt = null;
//Here I want to write code
//I want to access the DataTemplate defined in resources
//and set the ItemsSource of ItemsControl to something like this
// xxx.ItemsSource = obj; and then assign the DataTemplate to
//the CellTemplate of column.
//**Note :: ParameterLoop object has the IList Parameters**
column.CellTemplate = dt;
dg.Columns.Add(column);
i++;
}
}
