如何处理 Ultrawingrid (winforms) 底层数据集的异常

我有一个 UltraWinGrid，其后面有一个数据集。在数据表的 Row_Changing 事件处理程序中，我对数据进行一些检查，如果数据无效则抛出异常。我想在我的应用程序中显示此异常的消息。然而，UltraGrid 似乎捕获了异常并显示它自己的带有异常的消息框。如何防止显示消息框并在应用程序中捕获该错误？

private static void Row_Changing( object sender, DataRowChangeEventArgs e )
{
    if( <some logic to test the row values>)
        throw new Exception("you can't do that");
}

I have an UltraWinGrid with a dataset behind it. In the datatable's Row_Changing event handler, I do some checking of the data and throw an exception if it is invalid. I want to display a message for this exception within my application. However, the UltraGrid seems to catch the exception and display it's own message box with the exception. How can I prevent the message box from being displayed, and catch that error within my application?

private static void Row_Changing( object sender, DataRowChangeEventArgs e )
{
    if( <some logic to test the row values>)
        throw new Exception("you can't do that");
}

我解决了，但我想无论如何我都会提出这个问题（因为我已经把它打出来了）。

您需要处理UltraGrid的Error事件并将e.Cancel设置为true以防止弹出对话框：

public Form1()
{
    ...

    this.ultraGrid1.Error += new Infragistics.Win.UltraWinGrid.ErrorEventHandler(ultraGrid1_Error);
}

void ultraGrid1_Error(object sender, Infragistics.Win.UltraWinGrid.ErrorEventArgs e)
{
    //< deal with the error here>
    // set Cancel to true to prevent the dialog box from showing.
    e.Cancel = true;
}

I worked it out, but I thought I'd create this question anyway (since I have already typed it out).

You need to handle the Error event of the UltraGrid and set e.Cancel to true to prevent the dialog box from popping up:

public Form1()
{
    ...

    this.ultraGrid1.Error += new Infragistics.Win.UltraWinGrid.ErrorEventHandler(ultraGrid1_Error);
}

void ultraGrid1_Error(object sender, Infragistics.Win.UltraWinGrid.ErrorEventArgs e)
{
    //< deal with the error here>
    // set Cancel to true to prevent the dialog box from showing.
    e.Cancel = true;
}
