Is there any way to be selective about what is persisted?

Example - I want to persist what columns are visible in a radGrid - but I don't want to persist the page the user is currently viewing.

[Solved] Pass KeyValue?

Column Chart

I am working through the drill down chart example and all is great, but I want is to show the title of the product in the 'DataLabelsField' but pass the productID value when I click the column.

I'm passing the value client side
function OnClientSeriesClicked(sender, args) {
if (args.get_seriesName() != "Orders") $find("<%= rapD.ClientID %>").ajaxRequest(args.get_category());
}

My SQLDataSource has productID, ProductName and a count field.

I've been searching for ages now but can't find a solution to what must be simple.

Cheers,

Jon

Upgrade from Version 2011.2.915.40 to 2012.3.1308.40

I'm getting this run time error:

Could not load file or assembly 'Telerik.Web.UI, Version=2011.2.915.40, Culture=neutral, PublicKeyToken=121fae78165ba3d4' or one of its dependencies. The located assembly's manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040)

Can you give an update tutorial and help me solve the above problem. I can't find references to the old assembly in my project or in the GAC.

Thanks in advance.

GoToNextTab() and GoToNextPageView() methods not working..

Hello everyone,

I've got a RadTabStrip and a RadMultiPage that both work together on one page and are supposed to toggled between pages, depending on certain events and conditions.

My issue is that when i set them up, I can get the GoToNextTab() and GoToNextPageView() events to work when called on my first User Control (Step 1) but when attempting to call the method from my second User Control, the methods are unresponsive.

Here are theTabStrip and MultiPage controls on the default.aspx web form...

<telerik:RadTabStrip ID="BillPayNavigationRadTabStrip" SelectedIndex="0" runat="server" MultiPageID="BillPayRadMultiPage" Align="Justify"

Skin="Silk" CssClass="tabStrip" CausesValidation="false">

</telerik:RadTabStrip>

<telerik:RadMultiPage ID="BillPayRadMultiPage" runat="server" SelectedIndex="0" OnPageViewCreated="BillPayRadMultiPage_PageViewCreated"

CssClass="multiPage" BorderWidth="1" BorderColor="#888888">

</telerik:RadMultiPage>

default.aspx code behind...

protected void Page_Load(object sender, EventArgs e)

{

// Make sure we begin at Step 1 and disable the rest when the site loads for the first time.

if (!Page.IsPostBack)

{

RadPageView pageView = new RadPageView();

pageView.ID = "Bill";

BillPayRadMultiPage.PageViews.Add(pageView);

AddTab("Provider", false);

AddTab("Payment", false);

AddTab("Confirmation", false);

1. ColorCode scheduer timeslots based on some property.

UI for ASP.NET AJAX: Error thrown after updating from 2013.3.1324.40 to 2014.1.225.40

I used the Telerik Control Panel to update to 2014.1.225.40. I opened an existing ASP.NET web application and in Visual Studio 2010 and used the Telerik-->UI for ASP.NET AJAX-->Upgrade Wizard menu item to upgrade the solution. I left all values on the Solution Upgrade Wizard dialog at their defaults.

After the upgrade, running the project gives the error listed below. Copying the 2013.3.1324.40 versions of Telerik.Web.UI.dll and Telerik.Web.UI.Skins.dll makes the project run without errors. We need to either revert our affected projects to the 2013.3.1324.40 versions or know how to eliminate this error with the 2014.1.225.40.

Template Manager Preview Style

I have the ExternalDialogsPath set and working good but I cannot for the life of me style the preview of my templates, in the manager, the same as they are in the editor.
I have tried linking the style sheets in the TemplateManager.ascx and changing the style of class="templatePreviewer" - but to no avail.

How can I please?

Cheers,

Jon

editor.selectElement does not update the selection in Chrome

When I have an image surrounded by a link (<a ...><img ... /></a>), clicking on the image only selects the image. I have certain circumstances where I need to include the link in the selection, so I have tried to use this javascript. It works fine in Firefox (and not at all in IE because IE selection is lost when there is no text selected, see this old thread), but in Chrome the selection is not changed to include the <a> link.

console.log(editor.getSelectedElement().tagName); // "IMG"

var element = editor.getSelectedElement();

if (element.tagName == "IMG" && element.parentNode && element.parentNode.tagName == "A") {

console.log(element.parentNode.tagName); // "A"

editor.selectElement(element.parentNode.parentNode); // does nothing

}

console.log(editor.getSelectedElement().tagName); // "IMG"

Retrofitting existing Application using TabStrip

I am a newbie to Telerik and am using V2014.1.225.45.

We already have two separate application developed and plan on developing a third. I would like to make a single "parent" application that would display tabs for each of the current separate applications plus a third for this new application.

How do I make this "parent" page and can it support displaying "inside each tab the existing application without changes to application? Can each application have itself a set of nested tabs as well?
