Hi, Suppose you have a Dataset ds with with multiple tables in it. Now you need to remove one table from that dataset and copy that table to another datatable. So here is the code for that- DataTable dtnew = ds.Tables[0]; //copy specific table to one datatable dtnew ds.Tables.Remove(dtnew); // Now that table is removed from dataset.

Hi Raja, Below is the code to copy the table from the dataset and sort it on the basis of "ID" column: DataView d1t=ds.Tables[2].Copy().DefaultView; d1t.Sort = "ID"; DataTable finalNewTable=d1t.ToTable(); Remove that table from the dataset: dsNominations.Tables.RemoveAt(2); dsNominations.AcceptChanges()

Hi, You can try below code - DataTable dtnew = ds.Tables[0]; ds.Tables.Remove(dtnew); Above code will remove first datatable from dataset and add it to dtnew datatable.

Hello Raja, You can use below method to split your datatable in the multiples. private static List SplitTable(DataTableoriginalTable, int batchSize) { List tables= new List (); int i=0; int j=1; DataTablenewDt=originalTable.Clone(); newDt.TableName= "Table_" +j; newDt.Clear(); foreach (DataRowrow in originalTable.Rows) { DataRownewRow=newDt.NewRow(); newRow.ItemArray=row.ItemArray; newDt.Rows.Add(newRow); i++; if (i==batchSize) { tables.Add(newDt); j++; newDt=originalTable.Clone(); newDt.TableName= "Table_" +j; newDt.Clear(); i=0; } } if (newDt.Rows.Count>0) { tables.Add(newDt); j++; newDt=originalTable.Clone(); newDt.TableName= "Table_" +j; newDt.Clear(); } return tables; } in the above example, you should pass the maximum data table rows as an parameter batchsize. Hope, this will help you out. Feel free to write if more information is required. Don't forget to mark as answer if this helps.

Hi, Do you need to just remove one datatable from a dataset and copy it as another datatable? or do you need to split columns from a datatable and create a new datatable?
