You're in the
asp.net building controls
group:Dynamically loading ascx page and having events fire
asp.net building controls:
an answer. I am trying to create a simple web app, with a navigation on one side that will load up pages on the other. The nav side is a custom control, that has an event that fires upon click, and then sets a selectedindex. I am using the selected index to determine what ascx page to load up. I created a "LoadControl" function to load the ascx page and add it to the placeholder controls. This function gets called when the selectedindexchaged event fires (which is mapped to the nav control), and a viewstate variable gets set. The PostBack function checks for this variable and if there, calls the loadcontrol again. ** The ascx pages that I load have post back items on them, such as a textboxs and submit button. The nav events fire, which loads the ascx correctly, however the first time I hit submit button, the button click event (on the loaded ascx page) does not fire. Every time after that the event fires properly. From what I have read, when you load an ascx after the after the pageload has executed (ie. due to a event ) your events on the loaded page will not work properly because they were not loaded during pageload. And after the second click it worked because of my call to LoadControl in the postback. Some people have suggested to load all of your pages, and toggle visibility, but this really isn't an option since I plan on having a large number of pages on the site. Is there any way to make this work? Attached is the code snips. -- Page load <snip> if ( isPostBack ) { if (ViewState["Control1"] != null ) { LoadControl(); } } <snip> private System.Web.UI.Control home_control; private void LoadControl() { switch (FooterPanelBar.SelectedIndex) { case 0: home_control = LoadControl("a.ascx"); PlaceHolder_Body.Controls.Add(home_control); break; case 1: home_control = LoadControl("b.ascx"); PlaceHolder_Body.Controls.Add(home_control); break; } } private void FooterPanelBar_SelectedIndexChanged(object sender, EventArgs e) { PlaceHolder_Body.Controls.Clear(); // clear out the loaded one to perform switch to new ascx LoadControl(); ViewState["Control1"] = "Control1"; } Thanks, Shawn Meyer
hi Shawn,
You need to supply an id to your control. This is because the second time you load the control you are loading it in a different location. In your LoadControl method, right after you add your control to the placeholder supply an id and the problem is solved, like : switch (FooterPanelBar.SelectedIndex) { case 0: home_control = LoadControl("a.ascx"); PlaceHolder_Body.Controls.Add(home_control); home_control.id = "a"; break; case 1: home_control = LoadControl("b.ascx"); PlaceHolder_Body.Controls.Add(home_control); home_control.id = "b"; break; } [quoted text, click to view] "Shawn Meyer" <smeyer@interelate.com> wrote in message news:uwUUS155DHA.2576@TK2MSFTNGP11.phx.gbl... > Im sure this has been discussed here before but I have had no luck finding > an answer. > > I am trying to create a simple web app, with a navigation on one side that > will load up pages on the other.

if its not clear what i mean by a different location, i mean one time you
add it when the selected index changes, and another time you add it in page_load --supplying an id is the way to resolve.

This didnt work. The events on the loaded ascx will not fire, on the first
postback. After the first postback everything works as planned. Any thoughts?

This works perfectly. I had reconstructed your exact same scenario before
posting. With the only difference that i were using a radiobuttonlist control and loading controls in its selectedIndex changed event. Also note that initially when not supplying an explicit id I experienced the same problem you were facing. The fix is to supply an ID --this is because you are loading your controls at different locations like i stated. Private Sub Page_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load If IsPostBack Then If Not viewstate("controls") Is Nothing Then LoadControls() End If End If End Sub Private Sub LoadControls() Dim control1 As Control Select Case RadioButtonList1.SelectedIndex Case 0 control1 = LoadControl("webUserControl1.ascx") PlaceHolder1.Controls.Add(control1) control1.ID = "Mycontrol1" viewstate("controls") = 0 Case 1 control1 = LoadControl("webUserControl2.ascx") PlaceHolder1.Controls.Add(control1) control1.ID = "Mycontrol2" viewstate("controls") = 1 End Select End Sub Private Sub RadioButtonList1_SelectedIndexChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles RadioButtonList1.SelectedIndexChanged Dim control1 As Control PlaceHolder1.Controls.Clear() LoadControls() End Sub [quoted text, click to view] "Shawn Meyer" <me@me.com> wrote in message news:estABcb6DHA.712@tk2msftngp13.phx.gbl... > This didnt work.
