'Specified cast is not valid' with custom editor

Hi,
I've tried to create a custom editor for TimeSpan data field and it returns an error 'Specified cast is not valid' when I try to set value.

public class RadFilterTimeSpanEditor : RadFilterDataFieldEditor

{

RadMaskedTextBox _timePicker;

public override void InitializeEditor(System.Web.UI.Control container)

{

_timePicker = new RadMaskedTextBox();

_timePicker.Mask = "<0..5><0..9>:<0..5><0..9>";

container.Controls.Add(_timePicker);

}

public override Type DataType

{

get

{

return typeof(TimeSpan);

}

set {}

}

public override System.Collections.ArrayList ExtractValues()

{

ArrayList list = new ArrayList(1);

if (!string.IsNullOrWhiteSpace(_timePicker.Text))

{

TimeSpan ts = new TimeSpan(00, int.Parse(_timePicker.Text.Substring(0, 2)), int.Parse(_timePicker.Text.Substring(2, 2)));

list.Add(ts);

}

return list;

}

public override void SetEditorValues(System.Collections.ArrayList values)

{

if (values != null && values.Count > 0)

{

if (values[0] == null && !(values[0] is TimeSpan))

return;

TimeSpan ts = (TimeSpan)values[0];

_timePicker.Text = string.Format("{0:00}{1:00}", ts.Minutes, ts.Seconds);

}

protected override void CopySettings(RadFilterDataFieldEditor baseEditor)

{

base.CopySettings(baseEditor);

var editor = baseEditor as RadFilterTimeSpanEditor;

}

public partial class _Default : System.Web.UI.Page

{

protected void Page_Load(object sender, EventArgs e)

{

if (!IsPostBack)

{

RadFilterTimeSpanEditor editorTimeSpan = new RadFilterTimeSpanEditor();

RadFilter1.FieldEditors.Add(editorTimeSpan);

editorTimeSpan.FieldName = "ShipingDuration";

editorTimeSpan.DisplayName = "Shipping Duration";

}

protected void RadFilter1_FieldEditorCreating(object sender, Telerik.Web.UI.RadFilterFieldEditorCreatingEventArgs e)

{

if (e.EditorType == "RadFilterTimeSpanEditor")

{

e.Editor = new RadFilterTimeSpanEditor();

}

ListView Virtual Scrolling

Hello,

I was wondering if it were possible to implement virtual scrolling with the listview either by itself or using the datapager. Basically I am hoping that if the page is scrolled to the end of the listview, it will load the next page directly underneath it. Think Facebook and how they handle their wall posts/time line. Any advice would be great.

RadConfirm Not Defined

Whenever I try to call a function ("ItemErrorAlert") that contains RadConfirm from the code behind I receive a javascript error: "radconfirm is not defined". Although RadConfirm works as expected if I call it through the RadWindowManager, but I would rather call it in a javascript function.

See a code snippet below:

ASPX

radconfirm(message, confirmCallBackFn, 300, 100, null, "Title");

}

function confirmCallBackFn(arg) {

Issue with Ajax after Migration.

Hi Team,
We are migrating to Telerik's dll with version "2010.2.929.20". Currently we are facing an issue with RADAjaxManager.
Initially we declared RADAjaxManager in .aspx page and AjaxSettings where added dynamically in Page_PreRender event.
Now, after rewplacing the dll I've moved the dynamically added AjaxSettings from .cs -to-> .aspx.
telerik:RadScriptManager tag is on my Master page.

we are using Client Side API i.e.,

<telerik:RadCodeBlock ID="RadCodeBlock1" runat="server">
<script type="text/javascript" language="javascript">
    function RequestStart(sender, eventArgs) {
      alert('inside RequestStart');
    }
    function RequestEnd(sender, eventArgs) {
      alert('inside RequestEnd');
    }
</script>
</telerik:RadCodeBlock>
<telerik:RadFormDecorator ID="RadFormDecorator1" runat="Server" />
<telerik:RadAjaxManager ID="RadAjaxManager1" runat="server">
<ClientEvents OnResponseEnd="ResponseEnd" OnRequestStart="RequestStart" ></ClientEvents>
<AjaxSettings>
            <telerik:AjaxSetting AjaxControlID="Button1">
                <UpdatedControls>
                    <telerik:AjaxUpdatedControl ControlID="RadAjaxPanel1" LoadingPanelID="LoadingPanel1" />
                </UpdatedControls>
            </telerik:AjaxSetting>
</AjaxSettings>
</telerik:RadAjaxManager>

Problem is some how on button click none of the clientevents are getting called and neither do i see any difference in terms of page postback's. I mean Page does not seem to be ajaxified. Please help.

Thanks
