Hi Sao,
Greetings from Syncfusion support.
Query: "I want the DateUpdate or DateInsert to be
updated automatically without user input"
We have analyzed your query and we suggest you to achieve
your requirement using DefaultValue property of the GridColumn
Component. Using this feature, we can define default value for the column
while inserting a record.
Refer our UG documentation for your reference : https://blazor.syncfusion.com/documentation/datagrid/editing#default-column-values-on-adding-new-record
Please get back to us if you have further queries or if
above solution does not match your requirement.
Regards,
