[Eastern]

i am using RadControls Winforms Q1 2011 SP1 with Reporting Q1 2011 SP1,

Sometimes i'm getting the same error when i'm trying to display large amounts of data (+500 Pages). Is there a hard limit for memory etc.which is reached?

[Steve]

Hi guys,

We've released an internal build that improves performance by reducing the memory footprint and increaseing the speed of processing and rendering reports. Currently only the WinForms and WPF viewers take full advantage of these performance optimizations, however the WebForms and Silverlight viewers are next to be improved and we hope that we would have similar results for the upcoming Q2 release. Please upgrade and let us know if further help is needed.

All the best,
Steve

i found the source of the problem, the problem is with Scale Proportional  mode of picturebox when the picture is null.
some student objects have not any picture assigned to them , so when it want to scale proportional it , throw this exception.

i solve this problem by creating a method and do the scale things myself in it and assign that method to the Picturebox value.

hope it would be helpful.

I'm using the PictureBox with Scale Proportional mode too. But in my case it's working as expected even if there is no Value for the PictureBox. Think that's not the basic problem.

this problem occurs in pages bigger than 100. i think the memory problem have some effect when it want to change the scale of pictures.

is it safe to use 603 version in applications? is it a final release or it may change ?

[Michael Hilgers]

Okay, i integrated the internal build in our application and it seems to use less memory and to be a litte bit faster than before.

But now i'm creating a article catalog with pictures. This could be 10000 articles which all have a picture which are currenty stored in the file system. The report has to display 2 textboxes and the image for every article. When starting the preview the engine is working, than starts do display the pages (you can see the page count rising in the top bar of the report viewer). But then after approx. 50 pages it crashes with an GDI+ error. The used memory of the application rised to approx 1.3 GB, befor starting the report it was arround 100 MB.

Without the images on the report it's working perfect, but when the images come into the game, i always get the GDI+ error.

What can i do?

Kind Regards,
Michael

Any ideas?

I can't provide a demo because all data (pictures, database) are protected by a NDA.

Hi Michael,

The upcoming Q2 release should resolve this problem. We are currently in final stages of testing and polishing the release expected by the end of the week.

Best wishes,
