模块化弹出式扩展器错误 [英] Modular popup extender error

问题描述

成功解决了之前的所有问题后，现在卡在了代码的最后一行.那是从母版页开始的:

After successfully solving all the previous issue now im stuck on the final line of code.That is from the master page :

public bool CheckErrors()
{
    //Page x=new System.Web.UI.Page();
    ValidationSummary sum= new ValidationSummary();
    Page.Validate(sum.ValidationGroup);
    if (!Page.IsValid)
    {

        //this.EnsureChildControls();
        UpdatePanel update = new UpdatePanel();
        update.ID = "update";
        update.UpdateMode = UpdatePanelUpdateMode.Conditional;
        update.Update();

        modalPopupEx.Show();//error is in this line
        return false;
    }
    return true;
}

错误提示对象引用未设置为对象的实例.这是显示弹出窗口的最后一行代码...需要帮助

谢谢

Error say Object reference not set to an instance of an object.This is the last line of code to display the popup...Help needed

Thanks

推荐答案

谢谢，我已经解决了.

应该是

公共布尔CheckErrors()
{
//Page x = new System.Web.UI.Page();
ValidationSummary sum = new ValidationSummary();
Page.Validate(sum.ValidationGroup);
如果(！Page.IsValid)
{

//this.EnsureChildControls();
UpdatePanel更新=新的UpdatePanel();
update.ID =更新";
update.UpdateMode = UpdatePanelUpdateMode.Conditional;
update.Update();
modalPopupEx =新的AjaxControlToolkit.ModalPopupExtender();

modalPopupEx.Show();
返回false;
}
返回true;
}
谢谢大家的时间.

Thanks I have solved it.

It should have been

public bool CheckErrors()
{
//Page x=new System.Web.UI.Page();
ValidationSummary sum= new ValidationSummary();
Page.Validate(sum.ValidationGroup);
if (!Page.IsValid)
{

//this.EnsureChildControls();
UpdatePanel update = new UpdatePanel();
update.ID = "update";
update.UpdateMode = UpdatePanelUpdateMode.Conditional;
update.Update();
modalPopupEx = new AjaxControlToolkit.ModalPopupExtender();

modalPopupEx.Show();
return false;
}
return true;
}
Thank you all for your time.
