    AJAX >> Using AJAX to load a usercontrol that has JavaScript declared in it

    Normal 0 false false false MicrosoftInternetExplorer4   /* Style Definitions */ table.MsoNormalTable {mso-style-name:"Table Normal"; mso-tstyle-rowband-size:0; mso-tstyle-colband-size:0; mso-style-noshow:yes; mso-style-parent:""; mso-padding-alt:0in 5.4pt 0in 5.4pt; mso-para-margin:0in; mso-para-margin-bottom:.0001pt; mso-pagination:widow-orphan; font-size:10.0pt; font-family:"Times New Roman"; mso-ansi-language:#0400; mso-fareast-language:#0400; mso-bidi-language:#0400;} One of the things one needs to take care of when converting an existing application to use MS AJAX is inline script blocks inside pages or user controls. Problem with these is that if the control is sent to the client as a result of a partial page update (e.g. AJAX call) the inline script block simply won’t execute at all. The...

    Codeless client-side data-binding for your ASP.NET AJAX DataGrid?

    With RadControls for ASP.NET AJAX Q3 Beta we have provided great client-side data-binding improvement for the grid and now you can bind your data to any web service or page method completely codeless: ...   <ClientSettings>       <DataBinding Location="MyWebService.asmx" SelectMethod="GetDataAndCount" />  ...     Using this new approach you can get both data and total items count in a single request and if you turn on client-side caching the grid will perform request to the server only when needed! I'm really excited to announce that we extended this even more and now you specify following new properties: SortParameterType - SelectMethod sort expressions argument type. Can be set to "String", "List", "Linq" and "Oql". Default is...

    UI Automation/Accessibility in Silverlight 2, tools and resources summary

    The purpose of this post is to summarize the tools and resources for UI Automation/Accessibility testing in Silverlight 2 available at the present moment as well as to share a few details on what’s expected in the nearest future. There are a lot of resources on the web about Microsoft UI Automation framework and Active Accessibility so I’m not going to put any general information here. Still, you can refer to the list at the end of the post for additional information. The UI Automation testing tools are quite important to developers and testers (like me) that are interested in ...

    Accessing RadControls for ASP.NET Ajax items with WatiN(by using only the html elements)

    Are you curious how to deal with the complicated rendering of RadControls and WatiN? If so, I will shed some light on this. Here is an example how to print the text of the specific node of RadTreeView and how to expand it: [STAThread] static void Main(string[] args) { IE ie = new IE("http://demos.telerik.com/aspnet/prometheus/TreeView/Examples/Programming/DataBinding/DefaultCS.aspx"); Element ulElement = ie.Element("UL", Find.ByClass("rtUL rtLines")); Element firstLiElement = ulElement.DomContainer.Element("LI", Find.ByIndex(1)); Span textSpanElement = (Span) firstLiElement.DomContainer.Div(Find.ByClass("rtTop")).DomContainer.Span(Find.ByClass("rtIn")); Console.WriteLine(textSpanElement.Text); Span plusSpanElement = (Span)textSpanElement.PreviousSibling; plusSpanElement.Click(); }   Yet another example how to click on a ...

    The Grid in Microsoft ASP.NET MVC Beta

    As you know this week Microsoft released ASP.NET MVC Beta and I've updated my last grid example to the latest ASP.NET MVC version. I needed to change only two things: - Ajax.Form changed to Ajax.BeginForm/Ajax.EndForm - Html.SubmitButton changed to plain <input type="submit" /> and everything worked instantly!

    LINQ: Sequence contains no elements. Extension methods to the rescue.

    When you start playing with LINQ queries over sequences of elements (e.g. getting min / max value for enumerable source) sooner or later you will come across this one -- the InvalidOperationException (“Sequence contains no elements”). The problem occurs as by default queries like IEnumerable<T>.Min(…) and IEnumerable<T>.Max(…) do not play nicely if you try to execute them on an empty sequence and just throw the exception described above. Unfortunately these methods do not have a corresponding counterpart like Single(…) / SingleOrDefault(…) that is smart enough to query the sequence if it is not empty or alternatively use the default value without raising...

    Telerik.Charting in RadControls for ASP.NET AJAX Q3 2008

    There is no Telerik.Charting.dll anymore. It is now merged into Telerik.Web.UI. You will no more have to worry about its version and its registration in Web.config or replacing it in GAC when new version is out. Here are the steps you need to take when upgrading your applications from RadControls for ASP.NET AJAX version prior to Q3 2008 to RadControls for ASP.NET AJAX Q3 2008 and later: · If you have Telerik.Charting installed in GAC (this used to be the default RadControls installer action) replace the following Register directive <% Register Assembly="Telerik.Charting, Version=2.0.5.0, Culture=neutral, PublicKeyToken=d14f3dcc8e3e8763" Namespace="Telerik.Charting" TagPrefix="telerik" %>   with this one: <%@ Register Assembly="Telerik.Web.UI" Namespace="Telerik.Charting" TagPrefix="telerik" %> You will also need to remove...

    RadCombobox with disabled javascript

    Hi, all. We have a couple of requests from customers to do something and make RadComboBox working when javascript is disabled. And we did it. We implemented a new AccessibilityMode property which will render noscript tag containing a select html element. This will make the combobox control usable even if the javascript of the browser is disabled. Yes, it will be displayed like an usual drop down list but still it will be RadComboBox on the server. The following RadComboBox definition : <telerik:RadComboBox ID="RadComboBox1" runat="server" Width="250px" ForeColor="Green" AccessibilityMode="True" OnSelectedIndexChanged="RadComboBox1_SelectedIndexChanged" AutoPostBack="True"> <Items> <telerik:RadComboBoxItem runat="server" Text="RadComboBoxItem1" Value="RadComboBoxItem1" ForeColor="green"/> <telerik:RadComboBoxItem...
