Sorry to bother, but I've a quite frightening memory leak issue with RadWindowManager.
Very simple to reproduce. I've simply added a radwindowmanager to a page and client side I create a new window (I'm using google.it as target).
I've noticed that in IE8 (but it happens less extensively with chrome and firefox) if I continue to create a window and then close it and I look at the memory used by the browser it continues to get bigger.
I'm using Telerik 2010.2.713.35.

May you tell me if I can fix this issue someway?

Here is the code:

<%@ Page Language="C#" AutoEventWireup="True" %>

<%@ Register Assembly="Telerik.Web.UI" Namespace="Telerik.Web.UI" TagPrefix="Rad" %>

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

function openwindow()

{

var mywindow = radopen("http://www.google.it", null);

}

</script>

</head>

<body>

<asp:ScriptManager runat="server"></asp:ScriptManager>

<div>

<a href="#" onclick="openwindow();return false;">Open window</a>

<br />

<Rad:RadWindowManager runat="server" DestroyOnClose="true">

</Rad:RadWindowManager>

</div>

</form>

</body>

</html>

<body>

<asp:ScriptManager runat="server"></asp:ScriptManager>

<div>

<a href="#" onclick="openwindow();return false;">Open window</a>

<br />

<Rad:RadWindowManager runat="server" DestroyOnClose="true">

</Rad:RadWindowManager>

</div>

</form>

</body>

</html>

Changing Values in Custom Filtering Dropdowns

Hi

I have a radgrid with multiple custom filtering dropdowns.

I need to change the values in one of these dropdowns i.e. rebind to the datasource to get a subset of values based on the selection from the other dropdown.

Is this possible? Example code is below.

ASPX

<custom:DepartmentFilteringColumn DataField="Department_Name" HeaderText="Department" AllowFiltering="true"

UniqueName="Filter_Department" DataType="System.String" AutoPostBackOnFilter="True" CurrentFilterValue="%" >

<telerik:RadComboBox ID="radcomboDepartment" Runat="server" Skin="Telerik"

DataSourceID="dsDepartments" AutoPostBack="true" ShowToggleImage="True"

OnSelectedIndexChanged="radcomboDepartment_SelectedIndexChanged" DataValueField="ID"

DataTextField="Name" DataMember="DefaultView" MarkFirstMatch="True" Width="300px" EnableScreenBoundaryDetection="true">

</telerik:RadComboBox>

</ItemTemplate>

</custom:DepartmentFilteringColumn>

<custom:EmployeeFilteringColumn DataField="Responsible_Employee_Name_String" HeaderText="Employee Name" AllowFiltering="true"

UniqueName="Filter_Employee" DataType="System.String" AutoPostBackOnFilter="True" CurrentFilterValue="Unallocated" >

<telerik:RadComboBox ID="radcomboEmployee" Runat="server" Skin="Telerik"

ShowToggleImage="True" MarkFirstMatch="True" Width="300px" EnableScreenBoundaryDetection="true">

</telerik:RadComboBox>

</ItemTemplate>

</custom:EmployeeFilteringColumn>

NestedView client-side

Hi

I like the nested view model. However I am not a big fan of the small expand/contract button since I think it basically too small and might be a bit hard for the user to understand that it will expand the details for that record.

Is there a way I can allow the user to expand the row by clicking anywhere on it (possible with client-side selection).

Cheers,
Soeren

Data Binding Issue for Chart

Hi All,

I am binding RADCHART from webservice,
The webservice returns MONTH & Available services (%) for that month.
I use MONTH as a X axis data lebel and Available services as Data YColumn.

My webservice retuns MONTH only when the services have data for that month, due to this i am not
able to show some months for which there are no data available for services (not getting from WS).

My need is to show those months also where services data are unavailable (without showing Available services data).

I am thinking to populate the WS data in the arraylist and binding with RADCHART, but how can proceed with this, that's difficulty iam facing rightnow.

Plz anybody help me on this.
