Question

我正在尝试遍历sharepoint页面上的所有控件，出于测试目的，我只想输出控件ID

这是我正在使用的代码

Public Shared Sub SubstituteValues3（ByVal CurrentPage As Page，ByRef s As StringBuilder）

    'Page()
    '- MasterPage
    '- HtmlForm
    '- ContentPlaceHolder
    '- The TextBoxes, etc.

    For Each ctlMaster As Control In CurrentPage.Controls


        If TypeOf ctlMaster Is MasterPage Then
            HttpContext.Current.Response.Output.Write("Master Page <br/>")

            For Each ctlForm As Control In ctlMaster.Controls

                If TypeOf ctlForm Is HtmlForm Then
                    HttpContext.Current.Response.Output.Write("HTML Form <br/>")

                    For Each ctlContent As Control In ctlForm.Controls
                        If TypeOf ctlContent Is ContentPlaceHolder Then
                            HttpContext.Current.Response.Output.Write("Content Placeholder <br/>")

                            For Each ctlChild As Control In ctlContent.Controls
                                HttpContext.Current.Response.Output.Write(ctlChild.ID.ToString & "<br />")
                            Next
                        End If
                    Next
                End If
            Next
        End If
    Next

    HttpContext.Current.Response.Output.Write("--------------")
    HttpContext.Current.Response.End()

然而，它没有超过'MasterPage'输出。

我希望看到我的内容占位符中所有控件的名称，但我发现它有点令人困惑。

从Page.Master.Controls

开始

从那里你应该基本上工作

        For Each ctlForm As Control In Page.Master.Controls

            If TypeOf ctlForm Is HtmlForm Then
                HttpContext.Current.Response.Output.Write("HTML Form <br/>")

                For Each ctlContent As Control In ctlForm.Controls
                    If TypeOf ctlContent Is ContentPlaceHolder Then
                        HttpContext.Current.Response.Output.Write("Content Placeholder <br/>")

                        For Each ctlChild As Control In ctlContent.Controls
                            HttpContext.Current.Response.Output.Write(ctlChild.ID.ToString & "<br />")
                        Next
                    End If
                Next
            End If
        Next

Answer 2

MasterPage不是当前页面的控件，它是 Page.MasterPage

中的属性

Answer 3

我发现这段代码似乎列出了我需要的控件，但我认为它更像是一个黑客。

For i = 0 To CurrentPage.Request.Form.AllKeys.Length - 1
        If CurrentPage.Request.Form.GetKey(i).Contains("ctl00$PlaceHolderMain$") Then


            Dim key As String = CurrentPage.Request.Form.GetKey(i).Substring(22)
            Dim keyText As String = String.Format("[{0}]", key)

            HttpContext.Current.Response.Output.Write(keyText & "<br/>")

            'Text.Replace(keyText, CurrentPage.Request.Form("ctl00$PlaceHolderMain$" & key))
        End If
    Next

Answer 4

你可以简单地使用递归，而不是高效，但它很简单...尝试这种方法： public void getControls（控制输入）

{
    foreach (Control c in input.Controls)
    {
        Response.Write(c.GetType().ToString() + " - " + c.ID + "<br />");
        getControls(c);
    }
}

并称之为：

getControls(Page);

这将循环显示您网页上的所有控件并输出它们的类型 - ID 并将其打印到页面顶部...您还可以使用该代码构建一个列表或者你想做什么。
