如果您有一個TimeSpan屬性從類中暴露出來，需要綁定C1DataGrid到對象集合，自動生成不能編輯的TimeSpan列。使用DataGridDateTimeColumn并不適合這種場景，因為DataGridDateTimeColumn列的類型和TimeSpan有所區別。

最簡單的處理方法就是給DataGridDateTimeColumn設置CellEditingTemplate為C1TimeEditor。C1TimeEditor控件就是展示TimeSpan數據的特殊控件。如下的xmal代碼定義需求的模板：

<c1:DataGridTemplateColumn Header="Time">
<c1:DataGridTemplateColumn.CellTemplate>
<DataTemplate>
<TextBlock Text="{Binding TimeTaken}"/>
</DataTemplate>
</c1:DataGridTemplateColumn.CellTemplate>
<c1:DataGridTemplateColumn.CellEditingTemplate>
<DataTemplate>
<c1:C1TimeEditor Format="TimeSpan" Value="{Binding TimeTaken,Mode=TwoWay}"/>
</DataTemplate>
</c1:DataGridTemplateColumn.CellEditingTemplate>
</c1:DataGridTemplateColumn>

一種可以創建自定義列是從DataGridBoundColumn繼承，這對于使用AutoGeneratingColumns事件在運行時添加列是非常有用的。代碼參考：

public class DataGridTimeSpanColumn : DataGridBoundColumn
{
public DataGridTimeSpanColumn()
{
Initialize();
}

public DataGridTimeSpanColumn(PropertyInfo property)
: base(property)
{
Initialize();
}

protected void Initialize()
{
IsReadOnly = false;
}

public override object GetCellContentRecyclingKey(C1.Silverlight.DataGrid.DataGridRow row)
{
return "TimeEditor";
}

public override FrameworkElement CreateCellContent(C1.Silverlight.DataGrid.DataGridRow row)
{
var tb = new TextBlock();
return tb;
}

public override void BindCellContent(FrameworkElement cellContent, C1.Silverlight.DataGrid.DataGridRow row)
{
var tb = (TextBlock)cellContent;
var binding = CopyBinding(Binding);
tb.DataContext = row.DataItem;
tb.SetBinding(TextBlock.TextProperty, binding);
}

public override void UnbindCellContent(FrameworkElement cellContent, C1.Silverlight.DataGrid.DataGridRow row)
{
var timeeditor = (TextBlock)cellContent;
timeeditor.DataContext = null;
}

public override FrameworkElement GetCellEditingContent(C1.Silverlight.DataGrid.DataGridRow row)
{
var timeeditor = new C1TimeEditor();
timeeditor.Format = C1TimeEditorFormat.TimeSpan;
var binding = CopyBinding(Binding);
timeeditor.SetBinding(C1TimeEditor.ValueProperty, binding);
return timeeditor;
}
}
