How to programmatically add a row to a datagridview when it is data-bound?

问题

How can I add a row to a datagridview control if it is bounded to a datasource (datatable) ? Thanks!

回答1:

Add a row to the datatable, the datagridview will update automatically:

DataTable dt = myDataGridView.DataSource as DataTable;
//Create the new row
DataRow row = dt.NewRow();

//Populate the row with data

//Add the row to data table
dt.Rows.Add(row);

回答2:

• Create a class that corresponds to the data you want to display in your grid (same properties)
• In your data-binding function, get your query result, but put the result in a list (or any IEnumerable that suits you and the data binding)
• Create and add another object to your list according to your needs
• Bind the list
