Ajaxmanager issue with Ajaxcontroltoolkit release 40412

The Telerik Ajax manager is failing after we upgraded the ajaxcontroltoolik to release 40412.
Below is the error message we get

Error: i.get_postBackElement() is undefined

[Solved] Hidding a column

I am currently using a column with a boolean value to determine whether to enable/disable certain buttons on the itemselected event client side. The problem I have is that I do not want to display this column to the user but I can't set visible=false as then the javascript will fail. For a radgrid I can set Display=false, but that option does not seem to exist with a treeList?

<telerik:RadTreeList ID="radTreeList" runat="server" AutoGenerateColumns="false"

AllowPaging="false" PageSize="5" DataKeyNames="ID" ParentDataKeyNames="ParentTemplateId"

OnNeedDataSource="radTreeList_NeedDataSource" Skin="Web20">

<ClientSettings AllowPostBackOnItemClick="false">

<Selecting AllowItemSelection="True" />

<ClientEvents OnItemSelected="itemSelected" />

</ClientSettings>

<Columns>

<telerik:TreeListBoundColumn DataField="Name" HeaderText="Name" UniqueName="Name" />

<telerik:TreeListBoundColumn DataField="ModifiedTime" HeaderText="ModifiedTime" UniqueName="ModifiedTime" />

<telerik:TreeListCheckBoxColumn UniqueName="chkHasChildren" DataField="HasChildren"

HeaderText="HasChildren" />

</Columns>

</telerik:RadTreeList>

[Solved] RadEditor Toolsfile causes error

Hi. I want a simplified configuration of the RadEditor. However, I get an error:

"The string parameter 'key' cannot be null or empty"

All I have done is create a new page and add an Editor control. That obviously runs fine. I've created an "Editor" directory in my site and copy BasicTools.xml (from the telerik demos). I then set the editor control's ToolsFile property to reference the xml. Just making that change causes the site not to run and I get the above error message. What's wrong?

[Solved] TooltipManager with DayRender

Hi,

I am trying to show the tooltips of a special day with tooltip manager.

I am trying to follow the below example:
http://demos.telerik.com/aspnet-ajax/tooltip/examples/tooltipcalendar/defaultcs.aspx

I have the following code in page load and day render

protected void Page_Load(object sender, EventArgs e)

{

if (!Page.IsPostBack)

{

RadCalendarDay day = new RadCalendarDay();

day.Date = new DateTime(2011, 3, 25);

day.ToolTip = "Test Test.";

cal.SpecialDays.Add(day);

}

protected void cal_DayRender(object sender, Telerik.Web.UI.Calendar.DayRenderEventArgs e)

{

if(e.Day.Date == new DateTime(2011, 3, 25)){

TableCell cell = e.Cell;

cell.Attributes.Add("id", cal.ClientID + e.Day.Date.Day.ToString());

ttMngr.TargetControls.Add(e.Cell.Attributes["id"], true);

}

I also have the following items in the aspx page

<telerik:RadAjaxLoadingPanel ID="loading" runat="server" Skin="Default">

</telerik:RadAjaxLoadingPanel>

<telerik:RadToolTipManager ID="ttMngr" runat="server" Width="230px" Height="300px" RelativeTo="Element" >

</telerik:RadToolTipManager>

<telerik:RadAjaxPanel ID="ajaxPnl" runat="server" LoadingPanelID="loading">

<telerik:RadCalendar ID="cal" runat="server" ondayrender="cal_DayRender">

</telerik:RadCalendar>

</telerik:RadAjaxPanel>

But when I hover over the day it doesn't show the tooltip with the tooltip manager, a regular tooltip opens.

What am I missing here?

Thank you...

[Solved] ShowOtherMonthsDays with FocusedDate problem

Hi,

I am trying to change the month displayed with a button click in code-behind.

<telerik:RadCalendar ID="RadCalendar1" runat="server" ShowOtherMonthsDays="false"></telerik:RadCalendar> <br />

<asp:LinkButton ID="LinkButton1" runat="server" onclick="LinkButton1_Click">Prev</asp:LinkButton> <br />

<asp:LinkButton ID="LinkButton2" runat="server" onclick="LinkButton2_Click">Next</asp:LinkButton>

protected void LinkButton1_Click(object sender, EventArgs e)

{

RadCalendar1.FocusedDate = RadCalendar1.FocusedDate.AddMonths(-1);

}

protected void LinkButton2_Click(object sender, EventArgs e)

{

RadCalendar1.FocusedDate = RadCalendar1.FocusedDate.AddMonths(1);

}

When I go back to February 2011 from March 2011 I can only see days from March 2011 although Focused Date is a date from February 2011.

Thank you...

Disable RadScheduler for a selected date.

Hi.

I am using Telerik RadScheduler. I want to disable or rather make radscheduler invisible for a selected date.

It means if i select a date the rad scheduler calendar, the scheduler should not be visible or at least I should get a pop-up message saying that the date is invalid.
