Hi,

With the new version Q2 I found a problem. I had code with Q1 that "creates items" in the entries collection and aftre the user clicks save the collection is read again and differences are saved to the db (via oa).

Now, with Q2 however, the collection is not changed after deleting an entry.

Example:

ASPX:

<%@ Page Language="vb" AutoEventWireup="false" CodeBehind="Default3.aspx.vb" Inherits="WebApplication14.Default3" %>

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

<title></title>

<style type="text/css">

</head>

Public Property ContactId As Long

Public Property ParentContactId As Long?

End Get

Set(ByVal value As Long?)

End Set

End Property

End Class

In the example 2 items are added on loading-first-time. When you delete an entry in the box and click the first button (left side) you can see that the count is still 2 and not 1. When you go back to Q1, you will find that the count = 1.

Is this a bug or a feature? ;-)

Hi Erik,

The control is designed in such a way, so that if you attach a server event to it, the event is fired regardless of the AutoPostBack property. There is however a bug that I've found while testing your scenario - when you are handling the EntryAdded event, a postback it triggered when you delete an Entry also. This bug will be fixed in our next internal build. I've also updated your telerik points for pointing this out to us.

Hi Bozhidar,

The "by design" comes a long way with MS too... ;-|

I provided you code where you can see a BREAKING change in functionality between Q1 and Q2. In Q1 on postback the collection is correctly filled with the elements that where selected, in Q2 it is filled with the elements selected before postback; the initial items set server side. So: When I add 3 entries on load and delete one client side, I get 3 elements returned in stead of 2. This not only wrong, it is a breaking change. I connot see the "by design" here. Also, I cannot have this with development. I need continuity. Clients do not understand why I spend more time. I can invoice Telerik?

Secondly, 1 placed the 618 internal build this afternoon. Not only does the problem persist, an other problem created a JS error:
Uncaught TypeError: Cannot read property 'AbbreviatedMonthNames' of null
Telerik.Web.UI.WebResource.axd?_TSM_HiddenField_=RadScriptManager1_TSM&compress=1&_TSM_CombinedScri…:3248
So, I'm a bit tired of being the 'guinea pig' of Telerik. (See my track record of postings)
Today I spend again an hour upgrading to .618, testing and downgrading again with no results but waisted time.

Hello Erik,

After reinspecting the provided sample I found out what was causing the issue with deleting an entry client side, and it reappearing after postback. The problem will be resolved in our next internal build. I've also attached a modified version of the page, where I've included a workaround that verifies the fix, which you can use until the next internal build.

As for the second issue, its related to the Calendar and is already fixed in this week's internal build.

Please except our sincere apologies for the inconvenience caused.
