Page_ClientValidate（）对象预期的错误，找不到验证程序 [英] Page_ClientValidate() object expected error, cant find the validator

问题描述

我有一个包含一个空的ASP形式HomePage.aspx：面板，一个DropDownList让用户选择一个SPFielType ...索引变了，我的HomePage.aspx.cs页面获取文本选中，将加载的用户控件在面板内，该用户提供的控制将基于由用户和一个按钮调用validateForm（）函数所选择的spfieldtype生成控制...我的问题是，validateForm内部）的Page_ClientValidate（）函数（不能找到验证程序，我也试过给一个组名，但仍然没有工作。

当林把按钮里面我的aspx页面（不是动态渲染），它是验证我的网页（＆LT; ASP：按钮的ID =提交按钮的文本=验证=服务器/＆GT; ）。

但是，当林渲染它动态的，不能验证form..This是林试图做的：

I have a form HomePage.aspx containing an empty asp:Panel, a dropdownlist letting the user pick an SPFielType... on index changed, my HomePage.aspx.cs page will get the text selected and will load a user control inside the panel, this user control will generate a control based on the spfieldtype chosen by the user and a button calling the validateForm() function... my problem is that the Page_ClientValidate() function inside the validateForm() cant find the validator, i also tried to give a groupname but still not working.
When Im putting the button inside my aspx page (not rendering dynamically) it is validating my page.( <asp:Button ID="submitbutton" Text="Validate" runat="server" />).
But when Im rendering it dynamically , cant validate the form..This is what Im trying to do:

protected override void CreateChildControls()
{
    try
    {
        fieldRenderingControl = this.CreateFieldRenderingControl(this.FieldType);
        this.Controls.Add(fieldRenderingControl);

        Button button = new Button();
        button.UseSubmitBehavior = false;
        button.Text = "ValidateButton";
        button.ID = "ValidateButton";
        button.OnClientClick = "validateForm()";
        this.Controls.Add(button);

        RequiredFieldValidator newValidator = new RequiredFieldValidator();
        newValidator.Text = "***";
        newValidator.ID = "valideee";
        newValidator.EnableClientScript = true;
        newValidator.Enabled = true;
        newValidator.SetFocusOnError = true;
        newValidator.Display = ValidatorDisplay.Dynamic;
        newValidator.ControlToValidate = fieldRenderingControl.ID;
        this.Controls.Add(newValidator);

    }
    catch (Exception ex)
    {
    }

}

//所述CreateFieldRenderingControl（）函数将基于由用户选择的参数的字段类型生成控制

// the CreateFieldRenderingControl() function will generate a control based on the argument fieldType chosen by the user.

先谢谢了。

推荐答案

Sharepoint的有一个丑陋的怪癖它可以分配一个GUID是一个控件的ID。我看到这是由SharePoint产生试图使用这些GUID作为变量名的JavaScript。这是没有好 - 它打破了脚本 - 破折号在JavaScript变量名允许的。我怀疑这是您所遇到的问题。而且，我猜罪魁祸首是 this.CreateFieldRenderingControl（）。它看起来像方法生成编号...是标识一个GUID？如果是这样，请尝试使用一些安全覆盖标识，或许只是从该GUID删除划线。

Sharepoint has an ugly quirk where it can assign a Guid to be the id of a control. I've seen JavaScript that was generated by Sharepoint trying to use these Guids as variable names. This is no good - it breaks scripts - dashes aren't allowed in JavaScript variable names. I suspect this is the problem you are experiencing. And, I'd guess the culprit is this.CreateFieldRenderingControl(). It looks like that method is generating an Id... is that Id a Guid? If so, try to overwrite the Id with something safe, perhaps just remove the dashes from the Guid.

fieldRenderingControl.ID.Replace("-", "");

如果这不是精确解，希望它足以让你在正确的方向。

If this isn't the exact solution, hopefully it's enough to get you pointed in the right direction.
