Does anyone has same experience when using InsertAt to add datarow result in duplicate row happen at the end of Datatable?

Hi guys

As I mention above, I used InsertAt to add DataRow into DataTable which result in the duplicate/extra DataRow at the end of the DataTable.

I’m confused whether the Row Index is wrong or anything else.

If anyone has similar experience or ideas, please give me some advice where should I check again.

Thanks in advance

Somewhere the data is not getting cleared , which results in addition of duplicate rows.

can you please share more details ?
