Hi Sateesh,

I am afraid that I am unable to reproduce the reported issue. I have created a simple sample to test this issue and I am able to render the Grid without any out of memory exception and the sample is available from attachment.

Please have a look at the attached sample and if still the issue exists, could you please try reproducing it in the above sample and send us the modified sample so that we could sort out the cause of the issue and provide you a solution?


Thanks and Regards,
Bharath .M

Hi Bharath,

Actually i am binding datatable to the grid which is having number of rows more than 100000 and columns above 40. When data caching mode set to none then grid displays all the records. When data caching mode set to viewstate then it gives the Exception "System.OutOfMemeory". Same datatable data is converted to the xml and bind to the grid in your sample. Below is the attached sample.I tried by increasing the RAM of the Machine also.

Hi Sateesh,

Thank you for your interest in Syncfusion products.

We regret for inconvenience caused. We suggest you to set the DatasourceCachingMode property to none for larger data manipulation. Caching DataSource in viewState will create OutOfMemoryException for larger data due to limited resource.

Essential Grid now supports binding to LINQ through the PassThruGroupingDataSource. “PassThroughGrouping” helps to optimize the Grid performance. PassThrough grouping is a great way to take control of the data being retrieved from the datasource. You can use this technique for fast retrieval and rendering of larger data.

LINQ is a great way to retrieve data from your data source. LINQ lets you build intuitive query expressions in any language of your choice, with optional support for transforming, projecting and shaping data into different forms, before it is displayed in the UI.

Syntax:


Please find the sample for PassThruGrouping in following link:

Please refer the Online sample from the below link:
