Question

I have one DataSet that contain 2 relate DataTable (master and details). I want to copy data that match my filter (e.g. master data column A = ‘XXX’) to another DataSet.

Now I found that this process take a very very long time (about one hour for 1k records).

I want to know how to improve this processing time?

I’d say copy-ing 1000 records should only take a few milliseconds. Make sure there are no events firing or databindings doing strange things.. Maybe you should try without the relations but I believe enforcecontraints=false also disable foreign key checking..

The following code copies a complete dataset quite fast:

fDstDataSet.EnforceConstraints = false; foreach (DataTable fSrcTable in fSrcDataSet.Tables) {     DataTable fDstTable = fOpenOrders.Tables[fSrcTable.TableName];     foreach (DataRow fSrcRow in fSrcTable.Rows)     {         fDstTable.ImportRow(fSrcRow);     } } fDstDataSet.EnforceConstraints = true;
