Binding to a 40,000 records?

[SUNIL]

I have not tried WPF version in a real project, but would a WPF grid perform well with a dataset of about 40,000 records?
The datasource could be a dataset or List <> collection of 40,000 records.

Thanks

Hello Sunil,

There should be no problem to work with that amount of objects. You can also check out this demo which demonstrates a grid bound to 100 000 records. 

Kind regards,

Hi Milan,

I cannot view the link, since in IE it always crashes. Same in FireFox.
Is that demo you gave in link a part of examples in latest WPF controls set from Telerik?

Also, is the ability to handle a large number of records an advantage over Winforms grid from Telerik? I was weighing whether to use Winform grid or WPF grid from Telerik for a large number of records.

Thanks
Sunil

Hi,

 You may need to clear your XBAP cache. To do this you need to execute following command in your Visual Studio command prompt: "mage -cc". You cannot open an XBAP application in FireFox - I'm not sure how you get the same error since XBAP is IE only technology. 

Here are several Silverlight demos - the WPF versions are the same:
http://demos.telerik.com/silverlight/#GridView/Performance
http://demos.telerik.com/silverlight/#GridView/RealTimeUpdate
http://demos.telerik.com/silverlight/#GridView/UIVirtualization

You can check also your local version of our WPF demos for more info.

Hi Vlad,
I tried 'mage -c' command but it does not work in VS 2008 command window.
It says the first argument must be -New, -Update, -Sign

May be you missed telling me something else.

Thanks

Also, I downloaded the latest WPF controls, but some demos crash like the 'Server page,sort'. Also data virtualization demo does not work in downloaded demos.
Is this a bug with Telerik's WPF controls or a bug with the demos code or some issue on my end?

Thanks
