Because the .NET framework controls didn't plan in advance to be able to incorporate ASP.NET AJAX features into the framework, there can be certain things that make working with .NET controls harder. Take, for instance, the checkbox control. While...
In my talk, I was talking a little about the process of sending data from the server to client. In pretty much most data storage mechanisms or transports, the process of transporting data requires a serialization and deserialization process. For instance...
I found something interesting when dynamically creating a button in JavaScript. If I coded the button like the following: var button = document.createElement("INPUT"); button.type = "button"; parent.appendChild(button); button.value...
If you use web services to stream data to the client via the ASP.NET AJAX framework, you may experience challenges when you use LINQ to SQL or Entities as your data model. This is because LINQ objects retain all of their relationships, which the serialization...
JavaScript code overall isn't that difficult to write. It may sometimes be hard to come up with a particular task, but it isn't that hard to write. It's hard to get syntatically correct, even with all of the features VS 2008 has to offer....
When getting references to DOM object in ASP.NET AJAX script, you can use the $get() mechanism. $get is a shortcut for document.getElementById, and it works well, but there is something you have to understand about ASP.NET server controls. For instance...
The update panel was changed since the last beta and CTP versions. Before it didn't contain some of the postback triggers that were available. So I experimented with the new features, and it's pretty cool how the final version works. For instance...
I am about to destroy a segment of code in one of my projects, but before I do, I think it can help someone: < asp : GridView ID ="gvwProjects" runat ="server" ShowHeader ="false" EnableTheming ="false" AutoGenerateColumns...
The Calendar Extender is pretty neat in how it works, as part of the AJAX Control Toolkit. By clicking on a control or button, it renders a calendar, which has a link to today's date at the bottom, the calendar (and other month days) in the center...
The hover menu extender is a great extender in the AJAX Control Toolkit. Essentially, it is an extender that will appear whenever you hover over an HTML element. I use it to show helpful tooltips that exist in a panel, so when you mouseover a label control...
The modal popup extender is pretty cool; it pops up a modal form on the screen with whatever you want to see, prompting the user to perform some action. In previous iterations, you had to use a trick to show/hide the form though, by calling the javascript...
I had some problems with the Accordion control recently. I set it up similar to the sample in the toolkit that is included. It worked great; however, because I have server controls inside the Accordion panes, even though they registered in intellisense...
When working with the RC version of the ASP.NET AJAX Library, I was getting this error with the updatepanel controls and the scriptmanager control. I followed the Microsoft documentation and renamed everything to the asp prefix, that belonged to the ajax...
