如何开火活动 [英] How to fire an event
问题描述
您好，
我尝试在按钮点击事件下触发事件，也许任何人都可以给
a线索。
我已经让'具有PageIndexChanged事件的WEB网格：
private void DataGrid1_PageIndexChanged（对象来源，
System.Web .UI.WebControls.DataGridPageChangedEvent Args e）
{
//将CurrentPageIndex设置为用户点击的页面。
DataGrid1.CurrentPageIndex = e.NewPageIndex;
//重新绑定数据。
DataGrid1.DataBind（）;
}
在按钮点击事件下：
private void btnUpdtCmd_Click（object sender，System.EventArgs e）
{
}
我想解雇网格事件但是我不知道如何调用这个事件和
为它提供参数列表：
（对象源，System.Web.UI。 WebControls.DataGridPageChangedEv ent Args e）
谢谢，
Daniela
Hello,
I try to fire an event under a button click event and maybe anybody can give
a clue please.
I have let''s say a WEB grid with PageIndexChanged event:
private void DataGrid1_PageIndexChanged(object source,
System.Web.UI.WebControls.DataGridPageChangedEvent Args e)
{
// Set CurrentPageIndex to the page the user clicked.
DataGrid1.CurrentPageIndex = e.NewPageIndex;
// Rebind the data.
DataGrid1.DataBind();
}
Under a button click event:
private void btnUpdtCmd_Click(object sender, System.EventArgs e)
{
}
I want to fire the grid''s event but I don''t know how to call the event and
provide the parameter list for it:
(object source, System.Web.UI.WebControls.DataGridPageChangedEvent Args e)
Thank you,
Daniela

嗨Daniela，
Hi Daniela,
我想发射网格的事件，但我不知道怎么称呼这个事件和
为它提供参数列表：
I want to fire the grid''s event but I don''t know how to call the event and
provide the parameter list for it:
DataGrid控件上有许多事件。您只需要执行一个
操作，该操作将导致网格引发所需的事件。从外部提升控制事件并不常见。控件在内部提升他们自己的事件
。
你是否试图从你的按钮中提取PageIndexChanged事件
点击事件处理程序？
如果是这样，请更改CurrentPageIndex属性，并且应该通过
DataGrid引发事件。

There are many events on the DataGrid control. You just have to perform an
action that will cause the grid to raise the desired event. It''s not common
to raise Control events externally; Controls raise their own events
internally.
Are you trying to get the PageIndexChanged event to be raised from your button
click event handler?
If so, change the CurrentPageIndex property and the event should be raised by
the DataGrid.

感谢。事实上，我使用第三方WEB网格控件，出于某种原因，当我更改网格值
至代码时，
不会触发UpdateRowBatch事件。我需要通过其他方式提出这个事件。
我提供的样本不是最好的例子。
还有另外一种在外部触发事件的方法吗？

Thanks. In fact I use a 3-rd party WEB grid control and for some reason it
does not fire the UpdateRowBatch event when I change the values of the grid
thru code. I need to raise that event thru other means.
The sample I provided is not the best example.
Is there another way of firing an event externally?

嗨Daniela，
我见过一些提供Raise [Event]方法的控件，但通常不适用于
无论如何每个事件。我也不喜欢这个主意:)
我会联系制造商或找一个专门用于控制的论坛
人们可能会有有类似的问题。这绝对听起来像个臭虫。

Hi Daniela,
I''ve seen some Controls that provide Raise[Event] methods, but usually not for
every event anyway. And I don''t really like the idea either :)
I would contact the manufacturer or find a forum dedicated to that control
where people might have had similar issues. It definitely sounds like a bug.
