Programmatically Wireing Event handler on a loaded control.

[Christian]

Good Afternoon,

I am trying to wire up the ItemDataBound event of the RadListView control and encountering issues doing so. Let me describe the situation.

I am building a custom Sharepoint webpart that loads a control from an aspx page using Page.LoadControl. The loaded aspx page contains the RadListViewControl whose events I wish to wire up.

_ctrlGoogleCalendarSubscriptions = Page.LoadControl("/_controltemplates/NUGoogleCalendarSubscriptions.ascx");

To wire up the event I call;

 

 

 

_radCalendarListView.ItemDataBound += new EventHandler(this.radCalendarListView_OnItemDataBound);

I do this in the CreateChildControls method.

 

 

However when I compile I recieve the error "No overload for 'radCalendarListView_OnItemDataBound' matches delegate 'System.EventHandler'"

The method I am passing is below,

 

        protected void radCalendarListView_OnItemDataBound(object sender, Telerik.Web.UI.RadListViewItemEventArgs e)
        {
        }

I am able to wire up the DataBinding event without issue.

Am I missing something, is this not possible with the Rad Controls when loaded in this fashion?

Please let me know if you need any further details at all.

Regards,

Christian Brown

Hello Christian,

The delegate for the ItemDataBound handler of RadListView has difference signature, hence you can intercept that event programmatically in the following way:

_radCalendarListView.ItemDataBound+=new EventHandler<RadListViewItemEventArgs>(_radCalendarListView_ItemDataBound);

I would also recommend you avoid using ids starting with underscores for your controls.

Much Appreciated Sebastian,

I'd just realized that the signature was odd this morning when I actually looked at the Intellisense instead of simply working by rote. This did the trick.
