Page.Controls 母版页无法正常工作

Question

我有一个class，用于将所有页面控件的名称保存到数据库中。我们在第一次创建页面时使用它来设置翻译控件。

class 被发送到页面控件集合，然后它循环遍历每个页面，但是由于将所有页面附加到母版页，页面控件集合仅包含存在的四个内容区域并且不拾取任何内容else 在里面。

我已经尝试了几种方法来尝试解决这个问题，例如使用 div 或表格，但没有奏效，有人可以解释如何从母版页继承的页面中获取 Pages.Controls 吗？

我试过这个问题的答案：Loop through all controls on asp.net webpage

我从页面中获取的控件实际上似乎不包含子控件，因此无法将它们添加到列表中：

List<Control> foundsofar = null;
                    foreach (Control control in page)
                    {


                        foreach (Control c in control.Controls)
                        {
                            if (c is Control)
                            {
                                foundsofar.Add(c);
                            }

                        }
                    }

调用 class:

ArrayList PageObjects = GetPageControlIDs.AddControls(Page.Controls, array, constPageID);

添加控件class:

 static public ArrayList AddControls(ControlCollection page, ArrayList controlList, int PageID)
        {
            if (ObjectSetupSwitch == 1)
            {

                {

                    foreach (Control control in page)
                    {
                        if (control is Button || control is TextBox || control is Label)
                        {// This is cleaner
                            string ControlText = "";
                            string DescText = "";
                            if (control is Button)
                            {
                                Button btnNew = (Button)control;
                                ControlText = btnNew.Text;
                                DescText = btnNew.Text + " Button";
                            }
                            else if (control is TextBox)
                            {
                                TextBox txtNew = (TextBox)control;
                                ControlText = txtNew.Text;
                                DescText = txtNew.Text + " Textbox";
                            }
                            else if (control is Label)
                            {
                                Label lblNew = (Label)control;
                                ControlText = lblNew.Text;
                                DescText = lblNew.Text + " Label";
                            }
                            controlList.Add(control);

                            if (control.ID != null && control.ID != " ")
                            {

要从页面本身查找母版页控件，请使用以下代码。

此代码段将在页面代码中。

    protected void Page_Load(object sender, EventArgs e)
    {
        GetControl(this.Master.Controls);
    }

    private void GetControl(ControlCollection cc)
    {
        foreach (Control v in cc)
        {
            if (v.HasControls())
            {
                GetControl(v.Controls);
            }
            else
            {
                if (v is TextBox)
                {
                    string s = (v as TextBox).ID;
                }
            }
        }
    }

由于 System.Web.UI.MasterPage 是从 UserControl 继承的，它具有 UserControl 可用的所有属性和方法。

要使其成为可重复使用的功能，有很多方法。

希望对您有所帮助！！！希望这次我理解了你的问题:)

我最终找到了解决这个问题的方法，但无法找到一种简单的方法来获取所有控件。我不得不在其他控件中寻找它们，最终在这里找到了它们：

ArrayList PageObjects = GetPageControlIDs.AddControls(this.Controls[0].Controls[0].Controls[3].Controls[13].Controls[1].Controls[3].Controls, array, constPageID);

Page.Controls 母版页无法正常工作
