Radgridview crashes when displaying too many rows

[Wei Shiong]

Hi,

 I've encountered an issue where Radgridview crashes upon trying to display  too many rows ~1000+. The radgridview is placed under a data template which in turn is part of a hierarchy child template. Upon hitting the expand button to display the grid view,  the ui freezes after showing the rows. Upon reducing the number of rows in the data table to 60, all the rows appear without freezing. Any way I could get my 1000+ rows to appear without freezing the ui.

 Best Regards,

CH

Hi CH,

The most common reason for such behaviour  is if the UI virtualization functionality of RadGridView has been disabled due to the fact that the control is placed in a container that measures its children in an infinite size. You can learn more about this functionality in this help topic. In case this is not the cause for the issue on your end, please take a look at the Degraded Performance help topic on our documentation to see if one of the suggestions in it will help. 

If none of the suggestions in the article help, we'd appreciate a sample application demonstrating the degrading performance that we can troubleshoot on our end.
