Update RecurenceEditor using AJAX

Hello,
I have customized the appointment editing window to show in a RadDock as a pop-up. When I double click on an appointment, my customized form will be show. The application is running on SharePoint 2010

Heres the c# code..

protected void RadScheduler1_FormCreated(object sender, SchedulerFormCreatingEventArgs e)

{

appointmentRecurrenceEditor.ResetLayout();

if (e.Mode == SchedulerFormMode.Insert || e.Mode == SchedulerFormMode.Edit)

{

e.Cancel = true;

}

Telerik.Web.UI.Appointment appointmentToEdit = RadScheduler1.PrepareToEdit(e.Appointment, RadScheduler1.EditingRecurringSeries);

ScriptManager.RegisterClientScriptBlock(Page, GetType(), "formScript", "Sys.Application.add_load(openDoubleClickForm);", true);

PopulateEditForm(appointmentToEdit);

}

private void PopulateEditForm(Telerik.Web.UI.Appointment editedAppointment)

{

Telerik.Web.UI.Appointment appointmentToEdit = RadScheduler1.PrepareToEdit(editedAppointment, RadScheduler1.EditingRecurringSeries);

radPopSplitDuration.Value = appointmentToEdit.Duration.TotalHours;

RecurrenceRule parsedRule;

RecurrenceRule.TryParse(appointmentToEdit.RecurrenceRule, out parsedRule);

appointmentRecurrenceEditor.RecurrenceRule = parsedRule;

RadAjaxManager1.AjaxSettings.AddAjaxSetting(this.RadScheduler1, radPopSplitDuration);

RadAjaxManager1.AjaxSettings.AddAjaxSetting(this.RadScheduler1, appointmentRecurrenceEditor);

}

Ajax Manager in my page...

<telerik:RadAjaxManager runat="server" ID="RadAjaxManager1" EnableAJAX="true">

<AjaxSettings>

<telerik:AjaxSetting AjaxControlID="RadScheduler1">

<UpdatedControls>

<telerik:AjaxUpdatedControl ControlID="RadScheduler1" />

</UpdatedControls>

</telerik:AjaxSetting>

<telerik:AjaxSetting AjaxControlID="radPopSplitDuration">

RadDock

<asp:Panel runat="server" ID="DockPanel">

<telerik:RadDock runat="server" ID="RadDock1" Width="650px" Height="530px" Closed="true"

Style="z-index: 2000;" Title="<%$Resources:MyResources, SplitDetailsTitle%>">

<Commands>

<telerik:DockExpandCollapseCommand />

</Commands>

<ContentTemplate>

<div>

<telerik:RadNumericTextBox ID="radPopSplitDuration" runat="server" Width="80">

</telerik:RadNumericTextBox>

<telerik:RadSchedulerRecurrenceEditor runat="server" ID="appointmentRecurrenceEditor" />

</div>

</ContentTemplate>

</telerik:RadDock>

</asp:Panel>

ScriptManager in my master page

<telerik:RadScriptManager runat="server" ID="ScriptManager" EnablePageMethods="false" EnablePartialRendering="true" EnableScriptGlobalization="false" EnableScriptLocalization="true" />

Problem...
When I double click, A script error comes as 'Component 'SharedCalendar' was not found' .

If I were to remove the recurrence editor from the ajax manager in the aspx page and the ajax settings in the c# code, It will not give any error. It will update other controls such as 'radPopSplitDuration' but not the recurrence editor.

Any help would be gladly appreciated.

EmptyMessage and browser back button

I have a page with a NumericTextBox with EmptyMessage set. This works and the EmptyMessage text is shown when the page loads. There is a problem when you go to a different page and then click the browser back button to return to the original page. In this case the EmptyMessage text is not shown. I tried this in IE8 and Chrome and get the same results in both. Is there a way to make this work?

Here is the code:

<asp:TextBox ID="textExistingAssets" MaxLength="10" Width="100" runat="server" />

<asp:RequiredFieldValidator ErrorMessage="Field is required" ControlToValidate="textExistingAssets" Display="Dynamic"

EnableClientScript="False" runat="server" />

<telerik:RadInputManager runat="server">

<telerik:NumericTextBoxSetting Type="Currency" DecimalDigits="0" MinValue="0" MaxValue="2000000000" EmptyMessage="$">

<TargetControls>

<telerik:TargetInput ControlID="textExistingAssets" />

</TargetControls>

<Validation IsRequired="false" />

</telerik:TextBoxSetting>

</telerik:RadInputManager>

Multi-Hierarchy Radgrid Data Export

Hello,

I have a 3-tier hierarchy grid that, currently, displays great. However, I run into problems when I start trying to export the data to PDF/Export. Because it'd be a ton of code if I tried to post everything, I'll do my best using pseudocode. Currently, my report hierarchy goes like this:

<radgrid1>

<mastertableview>

<detailtables>

<gridtableview>

<nestedviewtemplate>

<radgrid2></radgrid2>

<radgrid3></radgrid3>

<radlistview></radlistview>

</nestedviewtemplate>

</gridtableview>

<columns>

...

</columns>

</detailtables>

</mastertableview>

<columns>

...

</columns>

</radgrid1>

Let's say radgrid1 holds customer names, and its one detail table holds product names, so that all the information in nestedviewtemplate holds production descriptions and such.

With the exception of of radgrid1, everything is databinded via the needdatasource event. When i go to export to excel, my code looks something like this:

radgrid1.ExportSettings.OpenInNewWindow = true;

radgrid1.ExportSettings.ExportOnlyData = true;

foreach (GridDataItem i in radgrid1.MasterTableView.Items)

{

i.expanded = true;

foreach (GridDataItem j in i.ChildItem.NestedTableViews[0].Items)

j.expanded = true;

}

radgrid1.MasterTableView.ExportToPdf();

The resulting PDF/Excel has all of the data from RadGrid1 and its child table exported, but nothing from the nestedviewtemplate. Essentially, all I am getting is a list of Customer Names and Product names under them in my report, with no product description data.

Any advice would be great.

Thank you,

Grid

[Solved] findItemByAttribute "ID"

Hi, I just wanted to know if it's normal that the client-side function findItemByAttribute() cant find any items when we use "ID" (Capitalization doesnt matter) as the Attribute name? If it is, any references that documents this?

this works:

var foundItem = menu.findItemByAttribute("MenuID", "1");

but not this:

var foundItem = menu.findItemByAttribute("ID", "1");

TIA

Filter and wildcards

Hi!

We are using a RadComboBox with filter="contains" with a webservice supplying results on demand. All is working well. However, lately, we have changed our search to use Lucene.NET indexing and not Database queries.
Now. Lucene.NET allows wildcards in queries, and this is where problems begin. Webservice returns a set of results, but RadComboBox doesn't display them due to Filter being set to Contains. If I remove Filter property, results are displayed, but not highlighted.
Also, Lucene.NET has it's own highlighter, which I tried to use mimicking what RadComboBox does, when filter is set, but to no avail, as em tag is apparently stripped form RadComboBoxDropDown when filter is not set. I also tried to use custom html tag, but that then gets displayed in combobox input field, which I don't want.

Is there a way of either implementing wildcards in RadComboBox filter or a way to override em stripping so that I can use Lucene.Net highlighter.
