I created a web user control which contains a dropDownList control.

ddlPatients.ascx

<%@ Control Language="C#" AutoEventWireup="true" CodeFile="ddlPatients.ascx.cs" Inherits="Admin_User_control_ddlPatients" %>

<asp:DropDownList ID="ddlCallsByPatient" runat="server" AutoPostBack="True" />



ddlPatients.ascx.cs

if (!Page.IsPostBack)

     BindDropDownLists();

And Drag And Drop it to aspx page.

Now I want to fire OnSelectedIndexChanged event to get the selected value of that dropDownList control in code behind.
Posted

in your web user control class define event
C#
public event EventHandler SelectionChanged_UserControl;
//use OnSelectionChanged event of dropDownList 

void Selection_Change(Object sender, EventArgs e) 
      {

      SelectionChanged_UserControl(sender,e);

      }

//you will get SelectionChanged_UserControl event where you use web control 
//this event will fire when selection of dropDownList changed 
   
its a simple solution

First in user control create a delegate above Page_Load() method

C#
public delegate void OnSelectedIndexchanged();
public event OnSelectedindexchanged Setactionname;


then in your dropdown selected index change add following line

SQL
if (Setactionname!= null)
                Setactionname();

then go to your ASPX page and
C#
UsercontrolName.Setactionname+= this.Mehtodnameonlocalpage;


create a function in your aspx code behind page and do what u need to do like
C#
private void SetSelectedActor()
    {

}
