Solution 1

C#

declare method  in uc.ascx.cs
 public event EventHandler<eventargs>Click;
public void Btn1_Click(object sender, System.EventArgs e)
   {
       try
       {
           //your logic here          
           this.Click(this.Btn1, e);
        }
       catch (Exception ex)
       {
       }
   }
and Main thing is that
 <asp:button id="btn1" runat="server" onclick="btn1_Click" />

write Button Onclick in design side

<%@ Register Src="AutoCompleteControl.ascx" TagName="AutoCompleteControl" TagPrefix="uc1" %>

i have made autocomplete control using web service...

<uc1:auctcompletecontrol id=DrpName Autopostback="true" runat="server" onTextchanged="DrpName_TextChanged"/>

I am asking about you loading usercontrol dynamically...

Devang Vaja 6-Dec-12 7:51am

i think u should add eventlistner to your button in codebehind when you load it dynamically... may be that will work:)

Control c1;
c1 = LoadControl("~/test.ascx");

madhuri@mumbai 6-Dec-12 8:31am

I have solved it,it doesn't need any eventhandler or any eventlistener,but another problem occured.

Devang Vaja 6-Dec-12 8:44am

what was the problem??

madhuri@mumbai 7-Dec-12 0:20am

Devang Vaja 7-Dec-12 0:21am

tell me due to what? may be i can Help u

madhuri@mumbai 7-Dec-12 1:09am

Ok..I just ask you one thing that,
I want to avoid all Usercontrol loading on Page_load event,I want to load that all UC when i required,like on any linkbutton click event,so which way you will suggest me..
I want to do all those for increase site performance.

Devang Vaja 7-Dec-12 1:21am

hey if You put load contol in page Load than it will definately Going To run EveryTime... But You can ignore the Buttons or links by their Unique Id and return from Your Event when It fires every Time...

if (Request.Form.Get("__EVENTTARGET") == lnkLinkToIgnore.UniqueID) return;

madhuri@mumbai 7-Dec-12 2:18am

no,I have not put it in Page_load,I have load it in Pre_init and linkbutton click.

Devang Vaja 7-Dec-12 2:32am

But Pre_Init will Going To load everytime on button click in page.. U can Check Conditions by above code Yaaaaaar...:)

madhuri@mumbai 7-Dec-12 2:45am
