Nested control's events not firing in UserControl

Posted By:      Posted Date: September 26, 2010    Points: 0   Category :ASP.Net

Hello I have a weird issue. I have a user control which I load dynamically using LoadControl. In this UserControl I have a button with assigned OnClick event, but when I click that button, the event is not fired. I'm populating the user control in UpdatePanel's Load event (I invoke __dopostback from JS).

<%@ Control Language="C#" AutoEventWireup="true" CodeBehind="ServiceInput.ascx.cs"
Inherits="uPay.UserControls.ServiceInputs.ServiceInput" ViewStateMode="Disabled" %>
    <div class="PopupFoot">
        <asp:Button ID="btnAdd" CssClass="PopupADD" runat="server" OnClick="btnAdd_Click" />

    protected void btnAdd_Click(object sender, EventArgs e)
        //Method never gets called :/

 Here I load user control in the page

protected void ServicesUpdatePanel_Load(object sender, EventArgs e)
        string arg = Request.Params.Get("__EVENTARGUMENT");
        if (arg == "ServiceInput")
            int serviceId;
            if (Int32.TryParse(hdnSelectedService.Value, out serviceId))
                using (Entities db = new Entities())

For a control which events are raised at design-time, run-time or both?

Hi. I have been getting several different errors on the my windows forms designer. I'm trying to implement an application with some complexity on the screen navigating since it includes several main views as also sub-views in which the sub-views are represented by user controls. I believe that some of my errors are related to the fact that I miss important information related the events that are raised while working in the windows forms designer. Is there any link that includes information about the events of a control that are raised at design-time, run-time or both? For example, if I override the OnLoad() method of a User Control, that method will be executed both at design-time and run-time. Knowing about this information has helped me resolving an issue related to duplication of columns on a customized DataGridView. Not 100% sure if it's possible to obtain what I'm asking for or if this information exists. If this information is not available what could I do in order to understand in more detail the kind of events that are raised in the design-time vs run-time? Can I debug an application in design-time using Visual C# 2008 Express Edition? I found this link that helps identifying the run-time and the design mode: http://dotnetfacts.blogspot.com/2009/01/identifying-run-time-and-design-mode.html This link has been helpful but I still feel that I need more information.

Using an Application Resource in Nested UserControl

Hello This problem has been niggling me for months and I just can't seem to get to the bottom of it. I have a UserControl, let's call it 'UC_List', and the ListBox in it uses a Style which I have declared in my Application.xaml file. When working with UC_List.xaml everything seems fine. I then place 'UC_List' into a UserControl, let's call it 'UC_Summary'. I have declared the namespace at the top of UC_Summary.xaml. The xaml code in UC_Summary now has an Error: Could not create an instance of type 'UC_Summary'. Now I cannot see anything in the Design window, only a warning saying 'Problem Loading, the document contains errors that must be fixed...' However when I run the application everything works fine! After a lot of trial and error I found that the cause of the problem seems to be the Style referenced in the Application.xaml. If I declare the Style in UserControl.Resources at the top of UC_List the error goes away and the graphics in UC_Summary return. I've so far duplicated my Styles into individual UserControls to work around the problem but this could easily lead to inconsistancies. If anyone can suggest anything I would be really pleased to try it. Thank you. Regards Chris

Nested controls in UserControl return null (FindControl)

UserControl with a control property?

Hi... I have defined a UserControl wich needs to reference another control like this: <ctrl:Cook TheList="listView1" DefaultFileName="MyRecipe"></ctrl:Cook> The code behind of the control has the property defined:         public ListView TheList { get; set; } But I have a runtime error saying: 'ListView' type does not have a public TypeConverter class. And in design time I get: Property TheList of type ListView cannot be specified as string.   I know WPF is trying to read a string instead of a ListView, but dont know the magic solution. Maybe a converter? Please suggest the simpler solution you can, because this is not a vital requirement on the app. Thanks in advance for any help
