[Solved] GridView causing out of memory exception (Q4 2010)

[Marc]

Any ideas on the following exception we are receiving in a grid with about 1000 rows of data.  I believe our specific version is 4_2010_2_1022.

System.OutOfMemoryException crossed a native/managed boundary

  Message=Exception of type 'System.OutOfMemoryException' was thrown.

  StackTrace:

Edit:
It appears that as users make changes in the grid, internet explorer is gradually using more and more memory until it eventually crashes. We need to isolate this behavior. Please help.

This is happening on multiple systems with both XP and Windows 7, both 32 bit and 64 bit.

Hello,

 Most probably you have Q2 2010 - we do not have Q4 release from more than 3 years. Can you try our latest official version - Q3 2010 SP1? Can you verify if the grid is not measured with infinity? The easiest way to check this is to look at the vertical RadGridView scrollbar - if present everything should be fine. 

Kind regards,
Vlad

We are running 4_2010_2_1022. Please clarify if this is the latest available to us.

Also, it looks like some memory is being release if I comment out the column with the DataTemplate. Is there some known memory issues using the datatemplate?

[Hristo]

Hello Marc,

You are running a latest internal build for our Q2 official release. The current official release is Q3 2010 and the latest LIB version is 2010_3_1407. You can download the Trial dlls from this link. If you need the Dev dlls you need to download our latest official release and then you'll see them here.

Even with the new binaries, I am seeing memory leaks directly related to the Telerik controls. As I switch the controls out for standard silverlight controls the memory leaks start to go away.

[Vlad]

Hi,

 Can you send us an example project where this can be reproduced? 

Kind regards,

[PRAMOD]

sir,
I am using RadGridView for binding Employee data,for 2000 employee record it is working fine but application crashes for nearly 6000 records.
please tell me what is the problem and what is solution for it.

[Vlad]

Hi,

 Most probably your grid is measured with infinity height. You can check this article for more info. 

All the best,
Vlad

Hi,

 We are using version 9.2.15.930 and are seeing an out of memory issue when trying to copy data (10k) from a grid or trying to preview as pdf. Could you please let us know if later versions handle large data without memory exceptions or is there a work around which we can use in the version we have?

 

[Stefan]

Hi Roshan,

Can you please confirm that you are using the UI for Silverlight, as the posted assemblies version is from the Reporting suite? If this is so, can you please confirm the UI for Silverlight version that you are using?

Regards,
Stefan
