失落的动态添加点击事件将每个TableCell的每个的TableRow [英] Lost dynamically added click events to each TableCell in each TableRow

问题描述

我开发活表的WebForms 。

我在每一个加入的TableRow这种控制每个TableCell的，当我加入新行到表：

I'm adding such control to each TableCell in each TableRow, when I'm adding new rows to the table:

// in some method, which creates the table

TableRow row = new TableRow();

// here goes other cells with text data

TableCell cellActions = new TableCell();
cellActions.ID = "offerActionsOfferId" + enumerator.Current.offerId;

// init button View More for cell
LinkButton buttonViewExpanded = new LinkButton();
buttonViewExpanded.ID = "buttonViewExpandedOfferId" + enumerator.Current.offerId;
buttonViewExpanded.CssClass = "table-actions-button ic-table-edit";
buttonViewExpanded.Click += new EventHandler(buttonViewExpanded_Click);
buttonViewExpanded.ToolTip = "some alt...";
cellActions.Controls.Add(buttonViewExpanded);
/* end of Action Buttons */

...

row.Cells.Add(cellActions);
this.tableMarket.Controls.Add(row);

但有一种失败与新的EventHandler（buttonViewExpanded_Click）方法。

表呈现在ASPX页面pretty很好，所有的控制都是可见的，但是当我尝试点击LinkBut​​ton的一个都出现故障。

Table renders in the ASPX page pretty well and all controls are visible, but a fail occurs when I try to click that LinkButton.

当我标志着一个断点，并试图抓住我的ASP.NET程序的执行在调试器中做一些分析工作方案 - 在页面刷新仅在Click事件处理程序没有一个断点被抓到。

When I've marked a breakpoint and try to catch the execution of my ASP.NET program in the debugger to make some analyse of program work - the page only refreshed and no one breakpoint in the click event handler has been caught.

为什么会出现这种问题？而如何使其工作？

Why does it occur? And how to make it work?

推荐答案

我不能测试你的code;它关系到其它类，如 InternalApi 。但是，这里是我发现了什么。

I cannot test your code; it ties to other classes like InternalApi. However, here is what I found.

您需要弄清楚的方式来加载 SetTableBodyForSceneMarket 在页的init 。

You need to figure out the way to load SetTableBodyForSceneMarket in page init.

这基本上就重装后动态创建的控件回;否则，这些控件将为空，并不能触发事件。

It basically reload dynamically created controls on post back; otherwise, those controls will be null, and cannot fire events.

protected override void OnInit(EventArgs e)
{
    base.OnInit(e);

    if(IsPostBack)
    {
        SetTableBodyForSceneMarket();
    }
}

private void SetTableBodyForSceneMarket()
{
  ...
}
