| 10/12/08 11:54pm | Javascript and jQuery Intellisense in Web Control Pages
Visual Studio provides fairly decent Intellisense and with a little bit of tweaking of your pages you can get Intellisense for jQuery and the Web Connection client script library. |
| 10/04/08 04:29am | Watch out for SYS(2335) in non-COM Applications
SYS(2335) can have some unexpected side effects if it is activated in non-COM applications even though the documentation states that in non-COM applications it is ignored. |
| 09/21/08 06:06pm | Header Manipulation in the Web Control Framework
Header access via is currently not supported in the Web Connection Web Control Framework, but that doesn't mean that you can't manipulate the header fairly easily. Using Expressions is one way that works today. In the next update there will also be an explicit Header object that allows dynamically adding content to the header that the top or bottom more easily. |
| 09/17/08 05:15am | Partial Control Rendering in AJAX Callbacks
Partial Rendering in AJAX callbacks allows you to create AJAX requests very quickly by reusing the HTML server side controls already produce. Web Connection makes partial rendering very easy simply by calling the .Render() method on any control on the page and returning HTML. In this example I demonstrate how to update a grid and an error display dialog in a single AJAX callback. |
| 08/16/08 04:26pm | Running Web Connection on Windows Server 2008 64 Bit
I've just got done upgrading my server to Windows 2008 64 bit and the process of getting Web Cinnection to run on it was pretty painless. A few improvements in IIS 7 make it easy to dial the 32 bit functionality of IIS to the Web Connection application. Here's how it works. |
| 07/31/08 04:47am | Http File Uploads in Classic and Web Control Framework Web Connection
File uploads are an operation that trip up Web developers frequently because the process of uploading files changes the rules of typical form behavior a little. Web Connection makes the process of handling file uploads pretty easy but depending on the approach - classic or using the Web Control framework - the process is handled a little differently. |
| 07/26/08 10:22am | Automating Configuration of Web Connection with Code
Every Web Connection application you build will need to be deployed at some point. Among the required tasks are copying files and then configuring the application to create virtuals, scriptmaps, set permissions and register your servers with COM. There are a lot of different approaches that you can take to configure your application, but Web Connection includes the tools to automate this process completely. Here's some boilerplate code you can use. |
| 07/15/08 12:44am | Handling BindingErrors in Tab Pages
The wwWebTabControl requires some special handling when dealing with binding errors as it's possible that binding errors are in controls that live in hidden tab pages. When clicking on error links it may be necessary to activate the tab page. Web Connection 5.37 includes a new global OnBindingErrorLink client function that can be used to activate a tab page. Here's how. |
| 07/04/08 01:38am | Dynamically creating TabPages with the wwWebTabControl
The wwWebTabControl in the Web Connection Web Control Framework is basically a Tabstrip control, which means it doesn't manage page content, only the display of tabs. A number of questions have come up regarding creating pages and tabs dynamically through code and although not built in this process is very easy to implement with a few lines of code. |
| 06/11/08 08:03am | Weird Performance Differences of PRG vs. EXE vs. COM Object in Large Apps
I've run into an application scenario where we are seeing radically different performance between the application running as PRG files, running as a standalone EXE or running as a COM object with perf differences of over 300% between fastest and slowest. |
| 06/08/08 07:05am | Repeater Item Referencing through the Page
If you've used the wwWebRepeater a lot in Web Connection you've probably found that it gets tricky to conditionally show content based on some global condition. There's a little trick you can use to easily access template controls directly from the page and set properties as long as the change is global and doesn't need to change based on each databound item. |
| 05/30/08 09:04am | Some new features coming in Web Connection 5.37
A few new features coming in the next Web Connection release to take a look at. These features are based on some recent work I've been doing with a client as well as some common usage scenarios that have popped up in questions on the message board. Let us know if you have thoughts on these features that are not quite final yet. Applies to Web Connection 5.37. |
