  How to access user control (ucButtons.ascx) events defined in master page from content page

  Jul 29, 2012 01:39 PM|LINK

  Dear Guys and Experts,

  I hope my subject is clear. anyway, i created a button and a dropdownlist in ucButtons.ascx web control. now, i defined it to master page as common controls and should be visible to any content pages. now, i wanted to modify the events of a button and the dropdownlists in every content page.

  i already created them but i have no idea how to call and modify its events from content page.

  The idea of it, is for example if i press the "Save" button, it will execute the codes that are defined in the content page.

  Thank you very much in advance. Jim.

  You'll want to expose the button in the user control.

  public Button ButtonPH { get { return this.Button1; } }

  then on the page load event or wherever in your content page you'll want to set the event.

   protected void Page_Load(object sender, EventArgs e)
      {
          ucButtons.ButtonPH.Click += this.MyButtonEvent;
      }
  
      protected void MyButtonEvent(object sender, EventArgs e)
      {
          Response.Write("hi");
      }

  Hi Jim,

  Please refer to en example below, which shows how to create a custom event on user control

  //CustomButtonControl.ascx
  
  <%@ Control Language="C#" AutoEventWireup="true" CodeBehind="CustomButtonControl.ascx.cs" Inherits="TestApplication.CustomButtonControl" %>
  <asp:Button ID="Button1" runat="server" Text="Button" OnClick="CustonButtonClickEvent"/>

  //CustomButtonControl.ascx.cs code behind
  
   protected override void OnInit(EventArgs e)
          {
              Button1.Click += CustonButtonClickEvent;
              base.OnInit(e);
          }
  
          public event EventHandler MyCustomButtonClick;
  
          protected void CustonButtonClickEvent(Object sender, EventArgs e)
          {
              MyCustomButtonClick(sender, e);
          }

  Here is how we use it in the other content page

  //default.aspx
  
  <%@ Page Language="C#" AutoEventWireup="true" CodeBehind="default.aspx.cs" Inherits="TestApplication._default" %>
  <%@ Register Src="~/CustomButtonControl.ascx" TagPrefix="uc" TagName="CustomButtonControl" %>
  <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
  <html xmlns="http://www.w3.org/1999/xhtml">
  <head id="Head1" runat="server">
      <title></title>
      
  </head>
  <body>
      <form runat="server" ID="some">
          <uc:CustomButtonControl runat="server" ID="ucCustomButtonControl"/>
  
          <asp:Label ID="Label1" runat="server" Text="Label"></asp:Label>
      </form>
  </body>
  </html>

  //default.aspx.cs
  
  protected void Page_Load(object sender, EventArgs e)
          {
              ucCustomButtonControl.MyCustomButtonClick += new EventHandler(MyCustomButtonClick);
          }
  
          protected void MyCustomButtonClick(object sender, EventArgs e)
          {
              Label1.Text = "Text Changed";
          }

  In the above example, when the custom user contrrol button is clicked "Label1.Text" property is changed in "MyCustomButtonClick" event, which is created in the user control. Above example is tested and working perfectly from my end, Hope this helps you in anyway.

  hello 2pac, thanks for your codes and ideas. its pretty clear to me. i have a question, what if i defined the custombuttoncontrol in my master page which is Site.Master <uc:CustomButtonControl runat="server" ID="ucCustomButtonControl"/>, can i can call those controls in my content page (default.aspx) and define an EventHandler inside default.aspx?

  Yes you can, Please follow the example below:

  //Site1.Master
  
  <%@ Master Language="C#" AutoEventWireup="true" CodeBehind="Site1.master.cs" Inherits="TestApplication.Site1" %>
  <%@ Register Src="~/CustomButtonControl.ascx" TagPrefix="uc" TagName="CustomButtonControl" %>
  <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
  
  <html xmlns="http://www.w3.org/1999/xhtml">
  <head runat="server">
      <title></title>
       <script  type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.7.2/jquery.min.js"></script>
      <asp:ContentPlaceHolder ID="head" runat="server">
      </asp:ContentPlaceHolder>
  </head>
  <body>
      <form id="form1" runat="server">
      <div>
          <uc:CustomButtonControl runat="server" ID="ucCustomButtonControl" />
          <asp:ContentPlaceHolder ID="ContentPlaceHolder1" runat="server">
          </asp:ContentPlaceHolder>
      </div>
      </form>
  </body>
  </html>

  Code behind

  //Site1.Master.cs
  
  public partial class Site1 : System.Web.UI.MasterPage
      {
          protected void Page_Load(object sender, EventArgs e)
          {
  
          }
          //expose user control to other content pages
          public CustomButtonControl MyButtonControl
          {
              get { return ucCustomButtonControl; }
          }
      }

  In content Page

  //ContentPage.aspx
  <%@ Page Title="" Language="C#" MasterPageFile="~/Site1.Master" AutoEventWireup="true" CodeBehind="ContentPage.aspx.cs" Inherits="TestApplication.ContentPage" %>
  <%@ MasterType  virtualPath="~/Site1.Master"%>
  <asp:Content ID="Content1" ContentPlaceHolderID="head" runat="server">
  </asp:Content>
  <asp:Content ID="Content2" ContentPlaceHolderID="ContentPlaceHolder1" runat="server">
      <asp:Label ID="Label1" runat="server" Text="Label"></asp:Label>
  </asp:Content>

  //ContentPage.aspx.cs
  
  public partial class ContentPage : System.Web.UI.Page
      {
          protected void Page_Load(object sender, EventArgs e)
          {
              var page = Page.Master;
              if (page != null)
              {
                  var customButton = Master.MyButtonControl;
                  customButton.MyCustomButtonClick += MyCustomButtonClick;
              }
          }
  
          protected void MyCustomButtonClick(object sender, EventArgs e)
          {
              Label1.Text = "Text Changed";
          }
      }

  In the content page we have a label "Label1", now we are going to use custom user control's click event to change the label text, by using,  @ MasterType directive, such as the one in the example, you can reference members on the master page.

  <%@ MasterType  virtualPath="~/Site1.Master"%>

  In Master page you need to expose the control:

  public CustomButtonControl MyButtonControl

  By doing the above, we can get reference of the user control from master page and use its click event to change the label
  
  Hope this helps

  Hello 2pac, you are one of the Genius that i knew, plus you're also very generous. This is EXACTLY what i'm looking for. i successfully applied it and it works perfectly!!! thanks a lot to you.

  I have one more question, is there any way to set <%@ MasterType virtualPath="~/Site1.Master"%> programmatically? or inside code behind? the fact is that, i have 2 master pages different structures and i want to change the virtualpath if i wanna use the code you shared.

  or can i define 2 different MasterType VirtualPath at the same time?

   <%@ MasterType virtualPath="~/Site1.Master"%>

   <%@ MasterType virtualPath="~/Preview.Master"%>

  i tried that format with 2 VirtualPath but it gives me error.
