How to: Add Rows to a DataTable

To add new records into a dataset, a new data row must be created and added to the DataRow collection (Rows) of a DataTable in the dataset. The following procedures show how to create a new row and insert it into a DataTable. Examples are provided for both typed and untyped datasets.

For this example, it is assumed that a dataset has a Customers DataTable and has two columns named CustomerID and CompanyName. Typed datasets expose the column names as properties of the typed DataRow object; in this case the CustomersRow.

• Declare a new instance of the typed dataset. In the following example, you declare a new instance of the CustomersRow class, assign it a new row, populate the columns with data, and add the new row to the Customers table's Rows collection:

  NorthwindDataSet.CustomersRow newCustomersRow = 
      northwindDataSet1.Customers.NewCustomersRow();
  
  newCustomersRow.CustomerID = "ALFKI";
  newCustomersRow.CompanyName = "Alfreds Futterkiste";
  
  northwindDataSet1.Customers.Rows.Add(newCustomersRow);
  

For this example, it is assumed that the untyped dataset has a Customers DataTable that has two columns named CustomerID and CompanyName. Untyped datasets require knowledge of column names or indices when coding. This example uses column names.

• Call the NewRow method of a DataTable to create a new, empty row. This new row inherits its column structure from the data table's DataColumnCollection. The following code creates a new row, populates it with data, and adds it to the table's Rows collection.

  DataRow newCustomersRow = dataSet1.Tables["Customers"].NewRow();
  
  newCustomersRow["CustomerID"] = "ALFKI";
  newCustomersRow["CompanyName"] = "Alfreds Futterkiste";
  
  dataSet1.Tables["Customers"].Rows.Add(newCustomersRow);
