I’m looking for a library that allows me to build applications in a way similar to Ext JS, with MVC approach (MVVM with PRISM is ok too on .net applications. I’m thinking about EF to handle database objects), expecially with some nice components like Ext JS provides.
I’m expecially thinking about the grid component which is really useful for managing applications.
I only found Telerik, but it costs $1200 and I’m looking for something possibly free or not more expensive than $500, I know my budget is low but I must consider I should even buy Visual Studio ($900) and it’s a lot of money as a single person to start a project.
Edit 1:
I found this library but the cost is basically the same as telerik: https://www.componentone.com/Store/?product=145
Edit 2:
This is a bit cheaper: http://www.devexpress.com/Products/NET/Controls/WPF/Grid/#main|buy
Edit 3:
This is even cheaper but it looks like missing filtering functionality for data-grid, which I think is a must-have: http://www.devcomponents.com/store/Scripts/prodView.asp?idproduct=26
You’re probably searching for WPF Toolkit and/or Extended WPF Toolkit.
Those are libraries with a set of controls for WPF available for free.
Plus, to be able to develop something in C#/WPF, you can use Visual Studio Express Edition which is free as well.
