Hi, can any of you recommend a good ajax gridview for asp.net? I have looked at telriks, but 1000$ is a bit too expansive for my taste. I don't need a whole lot of features, but rather it to be fast.
You can use Ajax.Asp.Net to wrap the standard gridview for full ajax functionality.
You can use a regular gridview control with an update panel. I used that combination in a majority of my applications with out any perfromance issues. Are you expecting to be querying a lot of data on a high traffic site?
You should just wrap your GridView in an update panel. Unless you are looking with something with a lot more features (including grouping, etc.). I've tried the Infragistics GridView and our company right now is using the ComponentArt toolsets, but I am not a big fan of either (especially not for the prices, and the ComponentArt stuff is way too complicated to configure for something simple in my honest opinion).
You could just use a completely client-side solution like YUI DataGrid or jqGrid for jQuery, then set it up to get your data via JSON from a WCF service or similar. This is a little more work than using a regular GridView in an UpdatePanel, but way-way more efficient.
you can also try Anthem. here is a a datagrid example too. I used it about 2-3 years ago and it worked really nice until i completely switched over to jQuery based AJAX stuff
In terms of performance, i found it slightly better than putting a data grid in an Update Panel though it also sends your complete viewstate back & forth.
Try using CoolGridView control (extends ASP.NET 2.0 GridView) and UpdatePanel from AJAXControlToolkit. http://johnsobrepena.blogspot.com/2010/02/coolgridview-february-2010-release.html
You can download the example from the latest release of CoolControls at codeplex.
