Modified today but still not for 13.1 !?
Why?

Robert, this example was already available for version 13.1 before today. Today was just a maintenance update without much changes.

Thanks Dennis.
Interestingly the version combo didn't show 13.1 yesterday.
I downloaded it anyway and it worked in 13.1 after changing .Net FW type to 4.

Hello, This is a great solution, but after upgrading to 13.2 it does not compile, Do you have a version for 13.2?
Thanks
Richard

waiting upgrade for 13.2

Just leaving a comment to be included in any update messages. Waiting for a remedy for this breaking change to be able to upgrade to 13.2 with many of my applications.

i have a suggestion to support such functionality of of the box

Could the example be updated to 13.2.6?

Guys, please refer to my answer in Q554368 (there you can find an updated version + a link to a hot fix build).

Right now, I have upgrade to v2013 vol 2.5
I use the most update code in "v2013 vol 1.4- v2013 vol1.9" . It get the error.
Would you please update this example to work with the most update version?

@Kanapol: This example will be updated once the version 13.2.7 is out (in a week or so). In the meantime, please check out my previous comment for a solution. Thanks.

The handler gridView1_CellMerge is not needed. It has no affect but makes the grid very slow.

Hello Leon,

The gridView1_CellMerge event in this example was handled for demonstration purposes and it works as basic merging. To increase the performance, you can remove the try-catch block from the gridView1_CellMerge event handler.

If you have other questions, please ask them in a separate ticket.

Do you perchance have an example of this in VB.NET ?

Thanks

If i use the RichEditDocumentServer, i lose all PageHeaders. Because you export it als html (only "one" page header) and import it again.

If i export it as rtf, and import it in your RichEditDocumentServer i lose all formats and text "positions" (Formating).

Any idea how i can export and import the XtraReport an also the nessesary Page headers?

Hi --

Is there an answer for Anastasius's question because I've just boarded the boat he is in. According to the logic you've mentioned below in your solution, You're first exporting the report to html and then saving it as doc or docx which generates the data correctly but I get only one table for all the sections in a report. I want different headers(tables) so I could later modify(add/delete columns and rows in separate tables in separate sections) them per my needs . That was the whole requirement behind needing a report export to doc and docx. Please suggest a solution and also please let me know when DevExpress is coming up with an integrated export to Doc and export to Docx features? In which release? Because that would eliminate lots of code in my application.

Thanks Much

Hello,
This works for ShowPreviewDialog but how the ShowRibbonPreview for RibbonControl in an MDI window?

Thank you for your help.

For simple Report, It is ok. But the problem for report have many tables, after use this way the layout are not acceptable.  We see many persons here posted this kind of request for many years. We all know that doc is MS private format. It is difficult to do that. But for docx, it is open standard and published by ms in 2006, they have open sdk. There're also many opensource ooxml library. Is it possible to implement docx first? Many other reporting tools,eg, fastreport,activereport,txcontrol,aspose,ssrs already have this functionality. Could you please take this into account? Thanks a lot for your great help.

This is an interesting topic, which should probably be explained more thoroughly in the "normal" documentation. We converted our application to adopt the DevExpress skinning, but we have dozens of threads and hundreds of forms and messages. Some messages will just not show up in the correct skin, which is driving us crazy. They must have been generated from a non-UI thread. But in a large app it's not so easy to keep every thread synced on the look and feel.
If the DefaultLookAndFeel would have been static for the application rather than per thread this would have prevented so many headaches (for many users if I go through the many threads on this).
So my question is: Why? Why is the ThreadStatic attribute applied, what advantage does this give over all disadvantages that makes it worth it? You did not chose the same solution for the default font, then why for the default look and feel?

Hi Mr. Murat YILMAZ, Can yo provide some example to use the class. I am looking it for shared parts

I implemented this OK in a Solution

When I eimplmented it in a different solution I got an Exception
"Message: Value cannot be null.
Parameter name: Application"

thrown at:

    public static void Initialize() {
            Guard.ArgumentNotNull(Application, "Application");

@Andrew: You forgot to add the following code:

public override void Setup(XafApplication application) {
            base.Setup(application);
            SequenceGeneratorInitializer.Register(application);
        }

You will not experience this and similar difficulties if you simply add the reusable module into your solution as per instructions above.

Hi,
Is this now supported in Middle-Tier XAF applications?

Thanks,

Carlitos

So, I have created a separate ticket on your behalf to process your inquiry more effectively:

How to implement cascaded combo box columns in ASPxGridView without using templates

Please refer to it for further correspondence.

I don't understand how this code work for new rows if in the grid_celleditorinitialize sub, if checks If (Not grid.IsNewRowEditing) Then before getting the filter value, so how does the second combo prefill for new rows after country is selected?

Please explain,
