How to call Parent Page property in UserControl

Question

I have my parent page as OPC.aspx where Addressdetail.ascx is declared as usercontrol.

Now I have made one property in my parent page(OPC.aspx) as

public string SelectedOptionUserControl { get; set; } 

Now I want to set property named SelectedOptionUserControl in usercontrol(Addressdetail.ascx) ie I want to set the property of parent page in child page

on Addressdetail.ascx code below

protected void Page_Load(object sender, EventArgs e)
    {
     this.Page.Master.SelectedOptionUserControl="abc";
     this.Page.GetType().InvokeMember("SelectedOptionUserControl", System.Reflection.BindingFlags.InvokeMethod, null, this.Page, new object[] { "abc" });
    }

I have tried this 2 ways but not working for me.

Answer 1

This

public string SelectedOptionUserControl { get; set; } 

declares a property, not a method.

So change

System.Reflection.BindingFlags.InvokeMethod

To

System.Reflection.BindingFlags.SetProperty
