问题描述

HI，带有编辑图像按钮的动态htmltable是从后面的代码构建的。 htmltable位于更新面板中。问题是事件处理程序未触发，但页面正在回发。任何帮助....

dataRow.Cells.Add(dataCell);

protected void imgEdit_Click(object sender, ImageClickEventArgs e)
{

表格中有多个图像按钮

推荐答案

通常如果在asp.net中创建动态控件，这个控件就无法在页面回发中保持状态。

用于维护动态的状态asp.net中的控件做一个人认为每当页面发布后重新创建 Page_Init 事件中的动态控件

Normally if create dynamic control in asp.net this controls are not able to maintain there state on page postback .
for maintaining the state of the dynamic control in asp.net do one think whenever page is getting post recreate those dynamic controls in Page_Init Event
