Capturing KeyPress Events on Mobile Devices

Question

User94112036 posted

All,

 I have a question in regard to UI experince when creating mobile web applications. I am very versed in C# and other languages, and know DotNet. Anyway I am creating a mobile web application that is to be used in conjunction with Windows CE devices, that have keypads and scanners attached. This is for a warehouse application, and I wanted to see if anyone had ever tried to capture a Keypress event, say the 1 key or "enter" key and detect that for allowing the mobile user to work with the key bad, vs. having to tab and enter, or click on the link with a stylus?

Basicaly I am creating a menu for the mobile web app with the numbers (1), (2), etc. beside them. The user's want the ability to press (1) and then that menu item [link] is activated and used. Anyway I know that most devices with a built in key pad can make use and handle the tab and enter key's themselves, but I wanted to offer an even faster shortcut, by allowing for the numerical key's to be associated and used with men items for a mobile ASP.Net page. Any advice on how doable this is, any pointers, etc. would be great!

thanks, Brandon ~

There's an attribute of WebForm.LinkButton called 'AccessKey'. Try using that. The thing, though, is that it does not work with Mobile:Link object. So you'll have to use Content Templating and add a WebForm.LinkButton instead of Mobile:Link. Go thru' this thread and see if it helps: http://www.dotnet247.com/247reference/msgs/33/168553.aspx

Brandon,

What version of Windows CE are you targeting?  The reason I ask is that it was only with Pocket IE 3 and later that scripting starting to show up. If you are using one that supports scripting you can connect with the onkeydown event.  It will require some experimentation to ensure that it works with the tags you are using.

References to get you started:

• Programmer's Guide to Internet Explorer for Microsoft Windows CE 3.0
• Is That Script In Your Pocket?
