i am having the following problems

1) how can we restrict the number of records per page in telerik reporting (web application).

2) telerik reporting is giving the memory out of exception if we have more number of records (more than 1000 record, each record is having minimum of 10 columns approximately) is there any restriction on memory size.  if we have restriction on memory size how can we fix that issue.

3) i generated the report, i came in good formatting , after i selecting the export option in pdf , in that the report came in different format i.e., all the things in collapsing, what is the solution for this or am i made any mistake .

Hello BVS Rao,

Up to your questions:

  1. As explained in the Understanding Report Sections help article, the detail section is printed once for every row in the data source and it is the section where you place the report items that make up the main body of the report. So based on the paper size (see report PageSettings), height of the detail section and top and bottom margins, you can make a simple calculation how many detail sections (i.e. number of database rows) would be shown on a single page.
  2. Keep in mind that handling reports (be it with large data or large number of items) usually requires additional resources in terms of powerful CPUs, and enough memory to handle all the operations. As far as the processing time and consumed memory is concerned, the complexity of the report layout, the complexity of the data calculations (aggregates, conditional formatting),  the rendering media, the size of the generated document (in pages), and the capabilities of the underlying machine are crucial. With that said, 1000 database rows with 10 columns would require at least 2 Gbs of RAM to complete and without a runnable sample project on our end, it is very hard to give appropriate advise especially when it comes down to making something work better. That is why we would appreciate if you send us a sample application that we can run on our end and observe the problem you report. Once we review it, we would be able to provide you with more info.
  3. We did not understand what is the exact issue here and would appreciate if you send us a sample project and a screenshot showing the issues.

Best wishes,
