I would like to create custom XrTable (e.g. : MyXrTable that contains MyXrTableRows/MyXrTableCells) control with some additional properties.
Is there any way ho to implement this? I think that it should be a workaround because there is no official support from DevExpress for this.
I have found following topics about this problem:
http://www.devexpress.com/Support/Center/p/S133680.aspx
http://www.devexpress.com/Support/Center/p/Q314421.aspx
Note: There is no problem to create custom control based on XrLabel or XrPanel but XrTable is more complex control.
I believe the best way to get guaranteed assistance with any DevExpress controls is contacting with DevExpress Support directly.
P.S. Note that FULL SUPPORT IS FREE during the evaluation period (30 days).

We have got a requirement to use a scheduler in one of our application. After browsing we found some tools to do this.
We found two main third party components for this - Telerik Scheduler and Devexpress scheduler.
We need another functionality like we need to drag some data from another control to this scheduler.
So both these gives this option
For Telerik : http://demos.telerik.com/aspnet-ajax/scheduler/examples/draganddropintegration/defaultcs.aspx
For Devexpress : http://documentation.devexpress.com/#WindowsForms/CustomDocument2274
So for this functionality which one is better; i can't find any exact comparison for the scheduler components of both products.
This is a subjective question but both control are decent and have great support and rich feature set. My advise would be to get a trial of both and see how it matches to your liking, general design and what you're trying to achieve with it.
I am using C# asp.net. I want to implement a commenting system which is similar to facebook commenting system look & feel. Please give your inputs.
When it comes to storing,retrieving and displaying comments yes asp.net controls come into use.
Other things being done, to accept a comment and display existing ones for that object (may be post) I would do:
1: Retrieve the comments for that object from database. (easiest way is to use SqlDataSource and set Select, Insert and Delete commands)
2: Use ListView control to display the retrieved data . Remember ListView should be customized to fit you need
Other databound controls are also usable. With these rich controls this task should be easy. Play with the templates these controls offer you and you can achieve almost any database related task.
Design and styling are sufficiently supported and still CSS + can be easily integrated.
I'm a pretty experienced Flex/.NET developer who is now learning html5/javascript. I've been playing with Ext Core and ExtJS for the last few weeks and I'm interested in whether/how folks are using these libraries to do bi-directional data binding on data that is not list based.
It seems like most of the binding support is directed at binding rows of data to grids. I'm interested in binding UI elements to arbitrary POJOs that are not list-based data.
Maybe I'm just not looking in the right places, but I'm not finding support for this.
I'm really interested in hearing what folks are doing in Ext OR what folks recommend as an alternative.
Although there is no out-of-the-box solution like the #Bindable from Flex for example, Extjs does offer the infrastructure to create bindings.
If you have a look at http://blog.dnet-ebusiness-suite.com/2012/03/data-binding-in-extjs-4-grid-form.html you'll see a demo for this where the models (filter instance and record instance, instances of Ext.data.Model managed or NOT managed by a store) are bound to different views. The functionality is achieved with a thin framework built on top of Extjs.
On the other hand, to bind arbitrary POJOs is exactly the same story, those have to implement an Observable and fire themselves some property change events which can be listened. The blog posts and the framework itself gives a good starting point on how to do this.
Another way/concept is http://www.sencha.com/forum/showthread.php?60809-Ext.ux.data.BindMgr-Databind-Manager which i used with extjs 3 and works fine.
A follow up... I never did find an ExtJS approach and moved on to other js frameworks/approaches and along the way learned about knockout: http://knockoutjs.com/ which is pretty darned awesome!
Are you looking for the BasicForm functionality? (Particularly: loadRecord)
If you want readonly display you can use DisplayFields or disabled TextFields or similar.
Take a look at jQXB , http://www.jqxb.altervista.com. It's seems to provides a very easy and powerfull api to bind data with html elems
I have been struggling quite a bit to get this JQgrid to work with Asp.Net.
I found asp.net samples online...but if I modify them according to my database,it flops.
Do I need to change the DataTable to JSON functions as well?
Out of my search,I found these 2 articles getting me pretty close...
http://arahuman.blogspot.com/2009/06/jqgrid-using-mvc-json-and-datatable.html
http://www.codeproject.com/KB/WCF/jqGrid.aspx
But then,it just doesn't work if I try a sample project with my own data table.
Can someone give me a hand please?
Thanks.
For ASP.NET we have created a server-side component, with programming experience / APIs very similar to the stock asp:GridView control. Note that the server-side component is not free though.
You can see more than 30 examples of jqGrid ASP.NET here
http://www.trirand.net/demo.aspx
and download the component and sample projects.

Have you made changes to the GridDemo.Home.GridDemo.setupGrid to match your database columns.
Jqgrid needs the setupGrid to be called with columns and other setting as per your preference.
If you post exact problem faced someone can help out.
I'm looking to find a decent calendar control for an ASP.Net application that allows each day to have an "ItemTemplate" type of declaration so that I can list things that are happening within each day. Something like the Club Starter Kit, only more robust and that can handle other datasources besides DataSets and DataTables.
I'm thinking about fixing that control to handle other types of datasources, but would much rather go with something better if I can find one. I'd even be able to work with some kind of client side "calendar" if one was available.
We actually ended going with the calendar control out of the Club Starter Kit (http://clubstarterkit.codeplex.com/) as the updated versions did what we needed them to do.
BaseCalendar may work (you can customize everything).
