IPostBackEventHandler没有传递事件参数 [英] IPostBackEventHandler not passing event argument

问题描述

我已经多次这样做但是由于某种原因它不起作用，加注

回发事件会触发，但传递给它的eventArgument是空的。这是一个简单的自定义控件实现

IPostBackEventHandler


我使用


string href = this.Page.GetPostBackClientHyperlink（this，

tab.TabID.ToString（））;


In回调argumts的痕迹列出但它永远不会到达


public void RaisePostBackEvent（string eventArgument）


{


this.Context.Trace.Write（" SelectedID =" + eventArgument）;


this.SelectedID = Convert.ToInt32（eventArgument）; < br $>

}


这必须成为众多更好的asp.net行为中的另一个，任何

的想法...谢谢......

I have done this many times but for some reason it''s not working, the raise
postback event fires but the eventArgument passed to it is empty. This is a
simple custom control that implements
IPostBackEventHandler

and I get the href for the a tag using

string href = this.Page.GetPostBackClientHyperlink(this,
tab.TabID.ToString());

In the trace for the postback the argumts is listed but it never arrives at

public void RaisePostBackEvent(string eventArgument)

{

this.Context.Trace.Write("SelectedID=" + eventArgument);

this.SelectedID = Convert.ToInt32(eventArgument);

}

This has got to be another one of the many wier asp.net behaviors, any
ideas...Thanks...

推荐答案

您是否将UniqueID分配给自定义控件的name属性？

Did you assign the UniqueID to the name attribute of the custom Control?

我做了这么多时间，但由于某种原因，它不起作用，加注
回发事件触发但传递给它的eventArgument是空的。这是一个简单的自定义控件，它实现了
IPostBackEventHandler

我得到了一个标签的href使用

string href = this.Page.GetPostBackClientHyperlink（this，
tab.TabID.ToString（））;

在回发的跟踪中列出了argumts但它永远不会到达

this.SelectedID = Convert.ToInt32（eventArgument）;

是设置了唯一ID并触发了RaisePostBackEvent但是eventArgument 是空的。

Yes the unique id is set and RaisePostBackEvent is fired but eventArgument
passed to it is empty.

你指定了吗？自定义控件的name属性的UniqueID？

参见下面的事件：


public void RaisePostBackEvent（string eventArgument）

{

//这写正确值

this .Context.Trace.Write（" eventArgument =" +

this.Page.Request [" __ EVENTAR GUMENT"））;


//这不会写出正确的值，它是空的

this.Context.Trace.Write（" eventArgument = " + eventArgument）;


this.SelectedID = Convert.ToInt32（eventArgument）;

}

See Event Below:

public void RaisePostBackEvent(string eventArgument)
{
// this writes the correct value
this.Context.Trace.Write("eventArgument=" +
this.Page.Request["__EVENTARGUMENT"]);

// this does NOT write the correct value, it is empty
this.Context.Trace.Write("eventArgument=" + eventArgument);

this.SelectedID = Convert.ToInt32(eventArgument);
}
