Error:- Tree view : Sys.UI.DomEvent.addHandler method, for Licensed version 2010.3.1215.40

Hello Telerik Team,

Its urgent... Today We have installed the Latest Telerik Licensed version No: 2010.3.1215.40.
But we have got the below error when click on Tree view OR Multipe TABS.

Problem is as Follows:
1) Click on any Tree view Node OR on Multiple Tabs, the Ajax control keeps on Loading and generates below javascript error:

"Sys.InvalidOperationException: Handler was not added through the Sys.UI.DomEvent.addHandler method."

Previously this was working correctly at all places with the version 2010.2.929.40

Let us know the possible solution for the same ASAP.

Regards
Sudhakar

RadMaskedTextBox setting the mask client side

Hello,
I do have a litte Problem setting the Mask of a RadMaskedTextBox via Javascript. Actually the mask gets set correct and I'd say my code works. However, the mask only gets displayed if I start typing in the Textbox. If I set the value to something that satisfied the mask, the value isn't displayed either.
I've already found the previous Thread on this topic, but neither setting the value nor setting the length worked for me.
Here's the code I use:

<telerik:RadScriptBlock ID="RadScriptBlock1" runat="server">

<script type="text/javascript">

function valueChanged(sender, eventArgs) {

var db1TextBox = $find("<%= txtFoo.ClientID %>");

var db1value = db1TextBox.get_value();

var db2TextBox = $find("<%= txtBar.ClientID %>");

var masks = [

new Telerik.Web.UI.RadLiteralMaskPart(db1value[0]),

new Telerik.Web.UI.RadLiteralMaskPart(db1value[1]),

new Telerik.Web.UI.RadLiteralMaskPart(db1value[2]),

new Telerik.Web.UI.RadLiteralMaskPart(db1value[3]),

new Telerik.Web.UI.RadLiteralMaskPart(db1value[4]),

new Telerik.Web.UI.RadLiteralMaskPart(db1value[5]),

new Telerik.Web.UI.RadNumericRangeMaskPart(0, 9, false, true),

new Telerik.Web.UI.RadNumericRangeMaskPart(0, 9, false, true)

];

db2TextBox._length = 0;

db2TextBox._setMask(masks);

db2Textbox._setValue('');

}

</script>

</telerik:RadScriptBlock>

<div>

<telerik:RadMaskedTextBox ID="txtFoo" Mask="<0..9><0..9><0..9><0..9><0..9><0..9>" runat="server" ClientEvents-OnValueChanged="valueChanged"/>

<telerik:RadMaskedTextBox ID="txtBar" runat="server"></telerik:RadMaskedTextBox>

</div>

Thanks in advance

Hide Detail table headers on Excel export when there are no data

Hi,

Is there a way to hide a detail table's headers during Excel export when there is no data for that detail table? I've set the setting

ShowHeadersWhenNoRecords="false"

on the detail tables. This works fantastic on the PDF export, but for some reason, the headers still display on the Excel export. The layout of the our grid is a master table with two detail tables underneath, to show different properties of the parent item. I bind all the tables dynamically, using OnNeedDatasource for the main table and OnDetailTableBind on the detail tables. The detail tables are not shown in the page, and only appear during the grid export.

Any help would be appreciated.

Can we limit the amount of callbacks when EnableLoadOnDemand and MarkFirstMatch=true?

I have a RadComboBox with EnableLoadOnDemand=true with an ItemsRequested event that fires when you type any character into the combobox text field. This all works, but it is too slow because of all the callbacks after every character is entered. Let's take this example:

I am looking for the value 1422 in my combobox list. I type '1' and it calls the server and shows me all items that start with '1'. Then I type '4' and it calls the server again to show me all items that start with '14'. This seems unnecessary. If we already have a list of all items that start with '1', then why do we need to call the server again to get the subset that starts with '14'? After the initial results are returned to the client, can I somehow search those results on the client for the '14' entries. After all, they have already been sent from the server, there's no need for any additional callbacks unless I delete back past the '1'.

Any help would be much appreciated.

thanks!

GridNumericColumn format

I think there is a bug regarding GridNumericColumn and formatting. I use currency format as follows: {0:#,##0;(#,##0);0} .
In the view mode column looks OK. The problem is when the row/item is in edit mode and yet the column is readonly.
If the column is readonly, I should see the same formatting as in the view mode. Is this a bug?

I see a lot of threads on the same topic and yet could not find definite answer from TELERIK on the topic.
Is there a manual fix?
