ASP namespace strong type access for dynamically loaded user control : DOTNET
This is a discussion on ASP namespace strong type access for dynamically loaded user control within the DOTNET forums in Framework and Interface Programming category; ASP namespace strong type access for dynamically loaded user control (web application, not web site) I have a user control in a web application which I dynamically load from an aspx page as follows: UserControl ctl = Page.LoadControl("./User Controls/ MailForwardingGrid2.ascx") as UserControl; form1.Controls.Add(ctl); This works fine.

 ASP namespace strong type access for dynamically loaded user control (web application, not web site) I have a user control in a web application which I dynamically load from an aspx page as follows: UserControl ctl = Page.LoadControl("./User Controls/ MailForwardingGrid2.ascx") as UserControl; form1.Controls.Add(ctl); This works fine. I have added 2 properties to the user control and would like to load the strong type version of the user control in order to set the new parameters at runtime. I would like to do something like the following: ASP.usercontrols_MailForwardingGrid2_ascx ctrl = (ASP.usercontrols_MailForwardingGrid2_ascx)Page.LoadControl("./User Controls/MailForwardingGrid2.ascx"); ctrl.SourceTypeID = Int32.Parse(context); ctrl.SourceID = id; Unfortunately, the ASP namespace is not showing my user control (the ASP namespace is not showing up at all).
