Hello Pooja,

Thank you for your post on this matter!

Before I can make a recommendation in this case, I’d like to get a better understanding of the situation you are seeing, as this Out of Memory Exception may be coming from other sources. For example, if you are using the XamDataGrid and are doing something that may be interfering with the virtualization of the grid, this could certainly lead to an Out of Memory Exception.

Would it be possible for you to please clarify the type of Infragistics for WPF control you are using in this case, as well as what you are looking to achieve with it?

Please let me know if you have any other questions or concerns on this matter.
