Hi ,

I have this task to do .

I have a user control that has organization and contact selector rad control . The contact selector has email shown if available. when the contact is selected, i need to show the email in the normal aspx textbox from the contact control. how can i do that? please help by looking at my code as i tried doing like this.

public event Action<string> OnContactChanged;  
   
   #region Page Events
   protected override void OnInit(EventArgs e)
   {
       base.OnInit(e);
       //ContactSelectorV2.OnContactChanged += ContactChanged;
       UserControls_ContactSelectorV2 contact = new UserControls_ContactSelectorV2();
       contact.OnContactChanged += ContactChanged;

   }

OnContactChanged is the event in the usercontrol which i tried to invoke here in the parent page.
when i wrote this method:

public  void ContactChanged()
    {

    }

and my textbox was txtEmail but this was not recognized.

my aspx code is like this for textbox:

<asp:TextBox ID="txtEmail" runat="server">

I have included the usercontrol like this :

<uc5:ContactSelectorV2 ID="ContactSelectorV2"  runat="server"/>

for which i have registered in the page like this

<%@ Register Src="~/UserControls/ContactSelectorV2.ascx" TagName="ContactSelectorV2"    TagPrefix="uc5" %>

Please help asap...
