Can't access GridView event at usercontrol by codebehind

Question

IpInterfaceUC UserControl

Answer 1

As per my understanding you need grid event handing (.ascx) on page/codebehind (.aspx).

declare eventhandler in userControl

 public event EventHandler  RaiseSelectedIndexChanged=delegate {};

handle userControl selectedindexchanged event in userControl.cs

   protected void gvChannel_SelectedIndexChanged(object sender, EventArgs e)
    {
        var raiseSelectedIndexChanged = RaiseSelectedIndexChanged ;
        if(raiseSelectedIndexChanged!=null)
        {
            raiseSelectedIndexChanged(sender, e);
        }
    }

register and use your userControl in aspx (which I hope you already did) this code will go in aspx page

handle the event in aspx code behind

    protected void OnRaiseSelectedIndexChanged(object sender, EventArgs e)
    {
       //handle your event and put logic 
    }

I hope i make it clear , let me know if it confuses you.
