Adding search functionality in a GridView in an ASP.Net application

Sometimes I get asked how to search through the results that are bound to a GridView control.

Using HTML 5 form input elements in ASP.Net applications
I am going to start a new series of posts that focus on HTML 5. HTML 5 is something I wanted to learn and finally I have covered enough ground to feel confident.HTML 5 gives us things like Semantic tags, the possibility to add video and audio in our pages without any plugins.With Canvas we can have very rich animations to our web pages.
I see that now with all these emerging technologies there are many things you can do on the client. JQuery is amazing and you can do so many things. Please have a look at my posts on JQuery. CSS3 is another big player that all developers should look into.
Some people might argue that front-end developers cannot use HTML 5 and CSS3 right now, because there are many browser versions from various vendors that do not support them or support them partially. IE6- IE8 do not support CSS3 (or there is a little support) but IE 9 supports many of them.In general (with some exceptions) IE9, Opera 10+, Firefox 3.5+, pretty much any reasonably recent version of Chrome, and Safari 3+ support CSS3.
CSS3 comes with Color enhancements,Transforms,Shadowing,Rounded corners and much more. -
