I have textboxes loaded with data on my ASP.NET MVC page. If the user clicks the Next button I need to load the textboxes with the relevant data. Similarly I have Next, Prev and Last buttons for record navigation. I have no idea on how to implement this. If it is JQuery how I can implement it? How do I implement it in ASP.NET MVC?
The good news is that there is a complete example of this in the Nerddinner ASP.NET MVC Walkthrough (pg 118-127).

I also recommend the book that this is the sample chapter of: Professional ASP.NET MVC 1.0 by Wrox Press.
change your model to implement a PagedList and then bind the each item in the result to a textbox, this can be done in Ajax using Jquery too

I am new to ASP.NET MVC .
To start learning on MVC, I was going through a tutorial on MVC, where they used the Page_Load event which is same as in Web forms.
Does MVC support events, and if so what events are supported?
If ASP.NET MVC does not support Page_Load event, then what is the alternative?
One thing that i was told before learning MVC was, 'Just forget everything about Webforms. It's old, and doesn't support separation actually.' Don't think about asp.Net webforms while learning MVC. MVC has a different life cycle.
An answer to your question is, MVC doesn't support Page_Load or any event, and it all depends on what you want to implement. Here are few tips:
1.) If you want to implement something before View (UI or html page) is rendered, you can write logic in controller before returning the View.
2.) If you want to implement something in the process of rendering page, you can use razor markups. It is quite easy to use razor.
3.) If you want to implement something after Page has been totally rendered, you can use jQuery's document.Ready().
You can start learning MVC here: http://asp.net/mvc
You should use Javascript/Jquery for event handling in MVC application. You may be use document.Ready() event handler to trigger the page load event and then handle your logic using javascript/jquery.
I don't want to make this into a "which is better... MVC or WebForms" type of question. Im sure that has been asked a bunch of times here already.
My Question: If I am building a MVC web project, why should I not use an ASP.NET datagrid control on one of my "Views" .aspx pages?
The control relies on Viewstate which isn't available in MVC. In addition, all the behavior is predicated on the WebForms event and postback model which you'd have to recreate in MVC to get them to work. You could search for alternate, MVC-friendly grids (perhaps jQuery-based). I know that Telerik has released a set of MVC controls under open source that might be helpful to you.
you can't use web forms controls in MVC because they depend on view state. Use the data grid of the Mvc Controls toolkit instead. It has paging, insert delete and update capabilities and it is completely templated (you can shap it as you like). Look at it here
The datagrid control depends on postback events which does not fit into the MVC way of thinking (the postback goes to the page code behind rather than the controller). You could use one without any postback features, i believe, but you may as well craft something directly.
Because the ASP.NET DataGrid / GridView has too much responsibility to fit into the MVC pattern. You'll have to add some code-behind to your view to databind the grid - code that belongs in the controller.
Anything that uses postback won't work with MVC, so the DataGrids paging and sorting won't be any good to you. So there really isn't any benefit to using it.
If you're looking for a flexible grid 'control' (MVC prefers the term HTML Helper), the MvcContrib grid is pretty good.
Im looking for a good example or tutorial which demonstrates adding and editing a data row (presented in a HTML Table) in a light box using ASP.NET MVC?
Many thanks
This should get you started: Simple ASP.NET MVC CRUD views opening/closing in JavaScript UI dialog
how to get a gridview in model view control,how to edit,delete the gridview with source code
Telerik has a great grid that's free (open source) for MVC. You can view it here, and the download is on their web site.
http://demos.telerik.com/aspnet-mvc/grid
You don't have access to ASP.NET controls in ASP.NET MVC, well not with the postback and viewstate stuff atleast.
However, you can create a nice GridView with ajax edit/delete capabilities by using something like jqGrid and a little code. Here are a couple of blog posts to get you started :

Hope that helps
Paginated List
Divides IQueryable source of any type on pages and returns items for current page. Useful for creating custom gridviews and pagers in C#, ASP.NET WebForms or MVC. Althought this code is used for pagnition, there is example on how to create Gridview with paging. Shouldn't be too hard to create CRUD actions from it.
I have an ASP.NET MVC application which uses plain HTML. I quickly need to add tabs and a datagrid to it. I've been evaluating ASP.NET AJAX and jQuery, but am running out of time to make a decision.
If I needed to add these 2 features quickly, how should I proceed? ASP.NET AJAX or jQuery?
If you are adding a grid to MVC, your best bet is JQuery. The ASP.NET DataGrid is not going to work with MVC, because MVC doesn't support postbacks. The ASP.NET AJAX tabs may not work either.
Here is a plugin for the tabs:

And here is a plugin for the Grid:

If you want to roll-your-own server-side GridView control for MVC, see here:

There is also a Grid Component in MVCContrib:
