asp.net – ModalPopupExtender和验证问题

我遇到的问题是,当页面上有验证,我正在尝试显示模型弹出窗口时,弹出窗口不会显示.并且通过使用fire-bug,我注意到一个错误被抛出.

用于显示弹出窗口的按钮导致验证设置为false,所以我被卡住导致错误的原因.

我创建了一个示例页面来隔离我遇到的问题,任何帮助将不胜感激.

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

解决方法

这是使用ValidationSummary和ModalPopup的问题.

见：http://ajaxcontroltoolkit.codeplex.com/WorkItem/View.aspx?WorkItemId=12835

问题是缺少“;”两个注入脚本之间.

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,它注入一个“;”进入页面启动脚本来修复错误：

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