Why do you think this is override? Is the property bound, and how?

Solution 1

What's the problem? What's wrong with MyDataGrid.Rowbackground = someBruh;?

Please see:
http://msdn.microsoft.com/en-us/library/system.windows.controls.datagrid.rowbackground%28v=vs.95%29.aspx[^].

See also this CodeProject thread: http://beta.codeproject.com/Messages/4078126/Datagrid-Row-background-binding-issue.aspx[^].

[EDIT]

Please see the answer by Espen and our comments in his thread. Crediting Espen's note on the styles, I mentioned the article which you could find useful:
WPF Themes and Skins Engine[^].

I have set these properties at design time to certain colors. and during run time I set RowBackground to some brush in the AutoGeneratecolumn event handler. but it do not have any effect.

Well, how do you know this code was called? Put a break point on it.

5'ed! Wayne Gaylard reply to the thread you referenced should work nicely:

Solution 2

Have a look at:Styling Microsoft’s WPF datagrid[^]

Rembemer that styles can be inherited[^] too.

Create new styles for your application that inherits from the ones you want to work with your application and apply appropriate setters. This way you will not need to handle any events in your application.

WPF DataGrid Practical Examples[^] provides a good introduction to the WPF DataGrid.

This is very appropriate, my 5.

So, maybe OP should review the design instead of just straightforward manipulation with the property (which he failed to achieve so far, please see his comment to my answer).

By the way, as to the last links: if I'm not mistaken, OP asked for a book or a site about this very control, and you appreciated my answer (very general though). Maybe this relatively short and nice article will serve as a book or a Web site for OP... :-)

Another 5... Oops! despite of the beta version of the site, only one 5 is taken into account. :-)

Thank you, Sergey!
Personally I think deriving from existing styles would be in line with the design philosophy of WPF :)

Sergey Alexandrovich Kryukov 26-Jan-12 17:08pm

Good style system should be cascading. I recently referenced a CodeProject article where the author introduced pretty much universal systems to support WPF skins. As far as I understand, it is nice and mature work; and it is inline with the design philosophy you mentioned.

It would take some time to find it on CodeProject again...

Pity, I'd like a link to that article ...

Sergey Alexandrovich Kryukov 26-Jan-12 17:14pm

Yes, found it; it was easy. I added the update to my answer and credited your comment. You will find that reference, after [EDIT].

I would appreciate if later on you could tell me your opinion.

Thank you,

Thanks :)
That should work well enough, and it will provide excellent flexibility.

Sergey Alexandrovich Kryukov 26-Jan-12 20:39pm

That was my impression, too.
Thank you.
