My .ascx file

 <asp:Label ID="uclbl" runat="server" />

My .ascx.cs file

    {
        get { return uclbl.Text; }

* i have registered the the control

My .aspx.cs file

Control _dummyUserControl = (Control)Page.LoadControl("~/UserControl/User1.ascx");
        _dummyUserControl.  ; //can not find the textforlabel here
        panelMain.Controls.Add(_dummyUserControl);

Answer 1

because you are making incorrect casting, you should cast to your user control type :

User1 _dummyUserControl = (User1)Page.LoadControl("~/UserControl/User1.ascx");
 _dummyUserControl.MyProperty = "SDfsdf"  ; //here you can find all your custom properties
panelMain.Controls.Add(_dummyUserControl);

Answer 2

您必须输入强制转换：

User1 _dummyUserControl = (User1)Page.LoadControl("~/UserControl/User1.ascx");
