btnDeleteInbox_Click不起作用？永远不会执行此方法

protected void gridInboxMessage_RowDeleted(object sender, GridViewDeletedEventArgs e)
{
    GridViewRow row = gridInboxMessage.SelectedRow;
    var inboxMessage = (from b in dc.PrivateMessages where b.Row.ToString() == row.Cells[0].Text select b).Single();
    dc.PrivateMessages.DeleteOnSubmit(inboxMessage);
    dc.SubmitChanges();
}

gridInboxMessage_RowDeleted不起作用？永远不会执行此方法

protected void gridInboxMessage_RowDeleting(object sender, GridViewDeleteEventArgs e)
{
    GridViewRow row = gridInboxMessage.SelectedRow;
    var inboxMessage = (from b in dc.PrivateMessages where b.Row.ToString() == row.Cells[0].Text select b).Single();
    dc.PrivateMessages.DeleteOnSubmit(inboxMessage);
    dc.SubmitChanges();
}

gridInboxMessage_RowDeleting不起作用？永远不会执行此方法

Answer 1

RowDeleted和RowDeleting事件处理程序可能没有被执行，因为它看起来好像没有任何东西正在调用delete命令。您没有生成删除按钮，而您的自定义按钮未调用删除命令。请参阅RowDeleting事件文档中的示例，了解如何实现事件的使用。请注意，该示例设置了＆＃34; AutoGenerateDeleteButton＆＃34;财产到真。当用户单击该按钮时，将触发RowDeleting和RowDeleted事件。

我不确定为什么你的自定义按钮的处理程序没有被执行。你能否确认你的网页确实在回帖？您是否能够通过代码进行调试以查看回发期间采取的步骤？正如穆罕默德所要求的，您能否包括您的页面加载代码以及任何其他相关代码？
