Adding Telerik Controls Dynamically into a Nested User Control

I am trying to add Telerik’s controls (like RadMaskedTextBox, RadNumericTextBox and RadDateInput controls) dynamically into a user control (under the Page_Init event) which is itself a child of another user control.

When I run the project, following exception occurred and nothing is shown in the user control.

“Microsoft JScript runtime error: Sys.ArgumentException: Value must not be null for Controls and Behaviors. Parameter name: element”

However, these controls are added directly on a .aspx page without any exception and it appeared that the Telerik’s controls get registered in the Page_PreRenderComplete event of an .aspx page and since this event does not exist in a user control therefore they are throwing the above exception.

RadButton & jQuery.validate()

I'm trying to use RadButton as a LinkButton and I'm validating the form using jQuery.validate().

I have the RadButton control set up as a LinkButton and for Single Click.

I'm having a problem where the validation runs and returns appropriate errors, but the button stays disabled. I've tried various approaches to enable the button, with no luck.

Anyone have a solution?

Button markup:

<telerik:RadButton ID="OrderButton" runat="server" Text="Order Check Copy" ButtonType="LinkButton" CssClass="css3Grad" ForeColor="White" SingleClick="True" OnClick="OrderButton_Click" BorderStyle="None" SingleClickText="Processing ..... " AutoPostBack="False" UseSubmitBehavior="False"></telerik:RadButton>

jQuery for the button's click:

$(document).ready(function ()

{

$('#<%= OrderButton.ClientID %>').click(function ()

{

$('#aspnetForm').validate({

});

$('#<%=accountNumber.ClientID%>').rules('add', { required: true, messages: { required: ' Required' } });

$('#<%=ckNumLabel.ClientID%>').rules('add', { required: true, messages: { required: ' Required' } });

$('#<%=dateLabel.ClientID%>').rules('add', { required: true, messages: { required: ' Required' } });

$('#<%=amountLabel.ClientID%>').rules('add', { required: true, messages: { required: ' Required' } });

if ($('#aspnetForm').valid() == false) {

var btn = $find('<%= OrderButton.ClientID %>');

btn.set_enabled(true);

}

});

[Solved] Highlight matches using LoadOnDemand

I am trying (once again) to use LoadOnDemand and still highlight matches to text typed by the user in the list. I've tried to use sender.highlightAllMatches(sender.get_text()) but I can not figure out how to call it AFTER the control is loaded. It seems like I need some kind of client side event after load to connect it to. Is there any solution that will allow me to fill the combobox in code and still highlight the matches without having to parse and highlight the match string in each item?

Telerik 2012 Q3 -- Binding SubReport

Hello

We just converted to this version of Telerik and are having problems with all of our reports that use subreports.
I have looked at several options that people have suggested but so far no luck.

Can someone please help?

Here is the code that we are using --

We set SubReportDS with
MainReport report1 = new MainReport();
report.SubReportDS = MyData;

and define SubReprtDS with --

public object SubReportDS
{
set {

MainReport report1 = new MainReport();

Telerik.Reporting.

SubReport subReport1 =
(Telerik.Reporting.SubReport)report1.Items.Find("subReport", true)[0];

Telerik.Reporting.

InstanceReportSource =
(Telerik.Reporting.InstanceReportSource) subReport1.ReportSource;

Telerik.Reporting.

Report sub2 = (Telerik.Reporting.Report)irs.ReportDocument;

sub2.DataSource =

value;
}
}

The end result of this is a report that contains that main section which is populated. It also
subReport sections but none of the subReport sections have data in them.

Any help will be appreciated.
Thank you - Raka.

Grid with Subgrid - Subgrid empty after postback

Dear,

I'm using the Telerik Grid for one of my webprojects.
The grid show data for a purchase order. For a line 2 subgrids can optionally contain data.
When loading the grid for the first time, it works fine.
When I edit a row, i do this with a server postback that shows a modal popup.
If the user saves changes for a line, another server postback happens and the grid is reloaded.
With this reload, only data in the main grid is shown. The subgrids don't show any data.
The need_datasource event is not even fired this time. However the code is exactly the same, so I don't understand what can be wrong.

Can someone help me with this weird issue?
Many thanks in advance!

Best regards, Koen

[Solved] Font Issue

Please take a look at the two screenshots I've provided. I don't know if you can tell but the fonts used by the RadComboBox are distinctly different.

Here's the thing: The two screenshots are of exactly the same RadComboBox in exactly the same app! The only difference is that the first one is of the app being run in VS2012 on my development machine (Win 7 OS) and the second is the app running under IIS7 on a different Win 7 machine.

The font shown on my dev machine is the one I like and what I was expecting to see. The one deployed to the server is peculiar and doesn't fit in with the rest of the fonts on the page.

I absolutely assure you that both copies are using exactly the same CSS file. They should be identical but they're not.

So the obvious two questions are: Why is this happening? How do I fix it?

Right-click Menu on rendered RadButton hyperlink?

Hi!

We have defined this button:

<telerik:RadButton ID="radButtonNewPlacement" Text="New Placement" ToolTip="#" ButtonType="LinkButton" EnableEmbeddedSkins="false" EnableEmbeddedBaseStylesheet="false" runat="server" CssClass="radButtonNoImage" OnClick="radButtonNewPlacement_Click" NavigateUrl="http://www.bing.com" />

...which results in this HTML:

<a id="radButtonNewPlacement" title="#" class="RadButton RadButton_Office2010Blue rbLinkButton radButtonNoImage" href="http://www.bing.com"><span class="rbText">New Placement</span><input id="radButtonNewPlacement_ClientState" name="radButtonNewPlacement_ClientState" type="hidden" /></a>

In IE, we would like the user to be able to right-click on this hyperlink and select 'Open In New Tab.' Unfortunately, this hyperlink does not work like a regular hyperlink. Why? And how can we make this behave?

Thanks!
Michael
