Hi bhojaraj,
Thanks for contacting Syncfusion support.
Based on your query we have prepared a Grid sample with more than 100
columns and defined
validationRules for several columns , but we were unable to reproduce the reported problem/scenario at our end as the Grid with more than 100 columns and validationRules was working properly. For your convenience we have attached the sample and video demonstration so please refer the below video demonstration and sample for your reference,
