Hi John, 

Thanks for contacting Syncfusion support. 

We checked in our sample by enable Unobstrusive and we unable to reproduce the mentioned issue at our end. In our sample we bind data for the grid in a button click.  

To find out the root cause, we need the following details.  

1. Share the code example of a Grid and server-side.  

2. Share the code example that you have binding data to a Grid.  

3. Have you using any adaptors like URL, remoteSave etc.? 

4. Essential Studio Version details.
