Screencast: Enable Server Mode using LINQ (ASPxGridView & XtraGrid)

In a previous post, I showed you how to use the powerful Server mode feature in ASPxGridView and XtraGrid against large datasets. The response to Server mode was so good that we've extended the ways that you can enable it.

You can now use a LINQ provider to work with our .NET grids in Server mode. The latest release, 2008 Volume 1, introduces two new datasources to support LINQ.   LinqServerModeDataSource supports the ASPxGridView and the LinqServerModeSource supports the XtraGrid. To use these datasources against either the ASPxGridView or XtraGrid, try the steps demonstrated in the short screencasts below.

The LINQ support in Server mode is bleeding-edge technology which gives you the performance gains for your projects. Check out this cool feature then let me know how you're using LINQ and how you plan to use these new LINQ datasources.

Mehul,

Sorry for the naive questions, but still:

What is the difference between LinqServerModeDataSource LinqServerModeSource?

Are there any performance gains of using new data sources as opposed to XPServerCollectionSource (esp, in the number of roundtrips)? Are there any performance measurements?

Best regards,

Rinat Abdullin

NB for the Web Admins: You can easily bind the RSS feed directly to devexpress domain (just requires minor DNS tweak). Feedburner supports that.

Hello Rinat,

"LinqServerModeDataSource supports the ASPxGridView and the LinqServerModeSource supports the XtraGrid" Smile

As for performance, the server mode is still blazingly fast with the new datasources. I'll see if there are any measurements. Thanks for the tip on the RSS Feed.

Mehul;

This would be my first to use LinqServerModeDataSource, and here is my question. As you know, ASP.Net provides LinqDatasource that you can use.

a) Is yours a replacement to the stock LinqDataSource?

b) If yes, can you point out what are the differences?

c) Can we use your DataSource with some of the ASP.Net stock (std) controls that come with VS2008 or should we use yours only for DX products?

Thanks!

Hello Ben,

LinqServerModeDataSource doesn't replace the standard class. It allows you to use an ASPxGridView (or XtraGrid) in server mode with any LINQ data source.

These new datasources can only be used with controls that support the IListServer (server mode) interface.

Thanks.

Hi,

Will this work for any Linq provider or are the DevEx Linq data sources specific to Linq2Sql.

Thanks,

Hello Kavan,

These new LINQ datasources works with other LINQ providers as well. Support has tested and verified that LINQ to XML works fine.

Thanks.

Hello Boris,

Sure, here you go:

Public Class Form1

    Sub New()

    InitializeComponent()

    linqServerModeSource1.QueryableSource = New DataClasses1DataContext().Customers

    End Sub

End Class

Thanks.

Hi Alex,

Yes, the LINQ support will work any LINQ provider. I believe LINQ to Entities should work as well.

Thanks.

Hi,

is it possibile to use LinqServerMode with the PivotGridControl.

it's another control that need to be used too in server mode!

Mehul Harry (Developer Express) said:

Hi Emanuele,

Unfortunately the ASPxPivotGrid control cannot use the LinqServerModeDataSource. Take a look at the following issue for an explanation:

Thanks.
