Hi,

I have created two threads including this.
The other thread's URI is
http://www.telerik.com/community/forums/silverlight/gridview/printing-data-which-we-are-getting-in-chunks.aspx

Its been quite some time but did not get any reponse.
Can telerik admin provide me solution for this.

Thanks,
Rajesh

Hi,

 Holding such amount of data in-memory will definitely lead to such exceptions. You should virtualize your data - something similar to this demo for example. If you want to print paged grid you can use the approach from this demo.

Thanks Vlad for your response.
The sample which you have created is using Observable collection(for 10 M record).
Thats why you are able to create 10 M records.
You try same thing with Datatable project provided by telerik with 100 columns you will get same error which i am getting.

The printing demo is not taking care about columns.So if there are more columns than a printable page can contain it will cut that.Isn't this the case??

Please provide me some solution for this.From last 5-6 days i am looking for solution for these issues.

Thanks,
Rajesh

Hi,

 The grid in our UI virtualization demo is bound to a collection of an item with a single property - cell values are virtual. The printing is not a built-in feature - you have full access to the code in our demo and you can modify it to fit your needs.
