    Using Telerik RadGrid in ASP.NET MVC together with RenderPartial, Ajax.Form, Ajax.ActionLink and UpdateModel

    I've made yet another ASP.NET MVC example with RadGrid for ASP.NET AJAX however instead of Html.Form and Html.ActionLink I have used Ajax.Form and Ajax.ActionLink: As a result now you have an ajax enabled grid with paging, sorting, select, edit, update, delete and insert: [Download]...

    AJAX >> Using AJAX to load a usercontrol that requires a custom css file

    Summary The technique demonstrates how to transform a non-AJAX scenario which adds a CSS <link> tag to the head of the page to work with AJAX, using a client-side javascript function to register the  <link>. Using AJAX in an application is probably the standard now. Partial page rendering offers a number of benefits such as increased page responsiveness, as well as close-to-desktop experience using AJAX-based toolkits such as RadControls for ASP.NET AJAX. However, adding UpdatePanels to the page and expecting that all of your “postback” logic will continue to function without changes is only true for simple scenarios. There are many more advanced...

    Create a Tabbed MDI using child forms

    If you are developing applications for Windows it is almost certain that you have incorporated the Multiple Document Interface (MDI) at some point. This is where you have a parent form that acts as the host for all forms within the application, minus a few exceptions. I know there are debates about whether MDI is an effective approach, but it doesn’t change the fact that MDI is very heavily used. I have found that the Tabbed Document Interface which is essentially an MDI that implements tab navigation between open items is pretty popular. As a matter of fact, this same...

    RadMenu for ASP.NET Ajax - Working with disabled JavaScript

    As you may know accessibility standards require a web page to work when JavaScript is disabled. In this blog post I will show you how to make RadMenu work even without JavaScript. I will also show how to make JAWS reader "see" all items rendered by RadMenu (even the hidden ones). Disabling JavaScript First we need to find a way to disable JavaScript in our browser of choice. For FireFox you need to install the web developer toolbar plugin. Then you can easily use the "Disable JavaScript" option: In Internet Explorer you should first edit the security settings for the zone in which your...

    RadChart &ndash; How to customize databound and auto-generated items?

    Imagine you have a databound RadChart and you need to customize the item labels, say you need to combine the values of two fields into a single item label. All you need to do is wire the ItemDataBound event, retrieve the ChartSeriesItem and customize it as per your requirements. You may use the actual data for this, here is an example:   protected void RadChart1_ItemDataBound(object sender, ChartItemDataBoundEventArgs e)     {         ChartSeriesItem item = e.SeriesItem;         DataRowView dataItem = (DataRowView)e.DataItem;         item.Label.TextBlock.Text = dataItem["FirstName"].ToString() + " " + dataItem["LastName"].ToString();     }   That was simple, but what about auto-generated axis items? OK, let’s start with some background – RadChart allows you to modify it at any stage of the page lifecycle, including events fired as...
