使用VB.NET的ASP.NET负载控制问题

Question

I have an ASP.NET page (Page A) that has some HTML and a single HTML control that loads a form (Control A). When I am finished saving the form in Control A, I want the HTML control in Page A to load the next control. I have been unable to make this work and any help would be greatly appreciated.

This is the code I am using in Control A to trigger the function in Page A to load the control.

    Protected Sub btnSave2_Click(ByVal sender As Object, ByVal e As EventArgs) Handles btnSave2.Click
    Try
        Dim ctest As New frmMain
        ctest.NextButton()
    Catch ex As Exception

This is the function in Page A that is being fired, but not loading anything

    Public Sub NextButton()
    Dim cname As New Control
    cname = LoadControl("EP/ctlE1_01_03.ascx")
    Me.dvContent.Controls.Add(cname)
End Sub

Answer 1

使用虚拟路径：

cname = LoadControl("~/EP/ctlE1_01_03.ascx")
