Hi Burke,
Thank you for using Syncfusion products.
I am not able to reproduce the issue of rebinding the data view in GDBG. You can call the ResetRange method by passing the column count value before rebinding the underlying data source. Please refer the below code snippet to achieve this:
this.gridDataBoundGrid1.Model.Cols.Hidden.ResetRange(1, this.gridDataBoundGrid1.Model.ColCount);
Please refer the sample in the below link which illustrates the above:
http://websamples.syncfusion.com//samples/Grid.Windows/F71802/main.htmPlease have a look at the above sample and if still the issue exists, could you please try reproducing it in the above sample and send us the modified sample, so that we could sort out the cause of the issue and provide you a solution.
