how to keep the rows ordering of datatable unchanged?

[thaopham215]

I have a datatable with the ordering of its DataClassIndex column before editting:

DataclassIndex 0 1 2 3 4

When I start modifying some other cells in this datatable, the ordering of DataClassIndex column changes to something like this

DataclassIndex 3 4 2 1 0

How can I modify a datatable content without altering the original order of the datatable.

Your question doesn't make sense to me.
A DataTable is just a table that contains a bunch of data in it.

What do you mean when you say the DataClassIndex changes?

Does the underlying data in the DataTable change (if so, why does it change? This doesn't happen without you doing something to it)

Or are you talking about a GridView displaying the DataTable data...and how the rows could possibly change if the user sorts the GridView??

@Frinavale
When I tried to modify some data in the datatable, the ordering of rows get changed. DataClassIndex is the name of the column in the datatable which contains the index of the rows of the datatable. Again, changing the data for some cells in the datatable alters the ordering of rows in the datatable which is not what I want. Thanks.

I've never heard of this.
Either you have some "sorting" going on in the control that is displaying the DataTable or you have some logic/code that is modifying the order of the rows. I can't guess at what you are doing that may be causing this problem...
