    Using Regular Expression TextBox

    I've already blogged about the new RadInputManager control in the Beta of Q3 2008 for RadControls ASP.NET AJAX. One of the other very useful features that you can now take advantage of in the RadInputManager is its RegExpTextBox setting. Regular expressions are a good way to validate text fields such as names, addresses, phone numbers, and other user information. You can use it to constrain input, apply formatting rules, and check lengths. If you capture input by using TextBox controls, you can use the RegExpTextBoxSetting settings to validate that input - for example to restrict the range of valid characters, to strip...

    A quick, but not so dirty Image Editor using the public RadEditor ImageEditing API

    The ImageEditor dialog in RadEditor has been around for about half a year, providing much wanted common image editing capabilities to the editor's end users.      This dialog in fact is the front-end of a basic image editing engine that has been built into the Telerik.Web.UI.dll. Some time ago our colleague Todd Anglin suggested that we make the API public so it can be used independent of the editor. Sounded like a good idea - and the coming Q3 2008 will allow you to take advantage of it :)  And since the functionality is already available in the already released RadControls Futures (which acts...

    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...

    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 ...
