[英]DataGrid drag/drop is not firing drop event when using caliburn micro
I have a datagrid defined in xaml as follow: 我在xaml中定义了一个datagrid,如下所示:
<DataGrid x:Name="ProcessInputImages"
ScrollViewer.HorizontalScrollBarVisibility="Hidden" RowHeaderWidth="0" AutoGenerateColumns="False" IsReadOnly="True" SelectionMode="Single" SelectionUnit="Cell"
IsHitTestVisible="True" AllowDrop="True" cal:Message.Attach="[Event Drop] = [Action ObjectDropped($eventargs)" >
....
</DataGrid>
and in my code behind, I have: 在后面的代码中,我有:
public void ObjectDropped(DragEventArgs e)
{
}
But the event is not firing when I drop a directory from explorer into it. 但是,当我从资源管理器中将目录拖放到该事件时,该事件并未触发。
Why it is not firing? 为什么不射击?
The problem was that xaml was wrong: 问题是xaml是错误的:
the correct syntax is: 正确的语法是:
<DataGrid x:Name="ProcessInputImages"
ScrollViewer.HorizontalScrollBarVisibility="Hidden" RowHeaderWidth="0" AutoGenerateColumns="False" IsReadOnly="True" SelectionMode="Single" SelectionUnit="Cell"
IsHitTestVisible="True" AllowDrop="True" cal:Message.Attach="[Event Drop] = [Action ObjectDropped($eventargs)]" >
.... ....
note ] at the end of cal:Message.Attach="[Event Drop] = [Action ObjectDropped($eventargs)] which was missing. 在cal:Message.Attach =“ [Event Drop] = [Action ObjectDropped($ eventargs)]”末尾缺少的注释[]。
