ModalPopupExtender和验证问题

Mal*_*chi 12 asp.net ajax modalpopupextender

我面临的问题是,当页面上有验证并且我试图显示模型弹出窗口时,弹出窗口不会显示.通过使用fire-bug,我注意到抛出了一个错误.

用于显示弹出窗口的按钮将原因验证设置为false,因此我不知道导致错误的原因.

我已经创建了一个示例页面来隔离我遇到的问题,我们将非常感谢任何帮助.

错误

function () {Array.remove(Page_ValidationSummaries, document.getElementById("ValidationSummary1"));}(function () {var fn = function () {AjaxControlToolkit.ModalPopupBehavior.invokeViaServer("mpeSelectClient", true);Sys.Application.remove_load(fn);};Sys.Application.add_load(fn);}) is not a function

这是使用ValidationSummary和ModalPopup的问题.

请看:http://ajaxcontroltoolkit.codeplex.com/WorkItem/View.aspx？WorkingItemId = 12835

问题是缺少";" 在两个注入的脚本之间.

他们的解决方案是创建/使用从ValidationSummary继承的自定义服务器控件,该控件注入";" 进入页面启动脚本来修复bug:

[ToolboxData("")]
public class AjaxValidationSummary : ValidationSummary
{
  protected override void OnPreRender(EventArgs e)
  {
    base.OnPreRender(e);
    ScriptManager.RegisterStartupScript(this.Page, this.Page.GetType(), this.ClientID, ";", true);
  }
}

您是否在页面上的任何位置使用验证组？当控件事件不属于验证组并且页面上的其他控件属于验证组时，我遇到了控件事件未触发的问题。
