Binding to Data

In This Topic

GcSpreadSheet supports binding to any object that implements the IEnumerable interface. This includes the Ilist, ObservableCollection, and WCF data source. Binding to data sets or data tables and the IBindingList data source is also supported.

GcSpreadSheet supports one way data binding. Changes to the source automatically update the target but, changes to the target are not propagated back to the source.

Specific columns can be bound with the DataField property.

Using Code

The following example binds the sheet with the DataSource property.

System.Data.DataTable dt = new System.Data.DataTable("Test"); System.Data.DataRow dr = default(System.Data.DataRow); dt.Columns.Add("Series0"); dt.Columns.Add("Series1"); dr = dt.NewRow(); dr[0] = 2; dr[1] = 1; dt.Rows.Add(dr); dr = dt.NewRow(); dr[0] = 4; dr[1] = 2; dt.Rows.Add(dr); dr = dt.NewRow(); dr[0] = 3; dr[1] = 4; gcSpreadSheet1.Sheets[0].AutoGenerateColumns = true; gcSpreadSheet1.Sheets[0].DataSource = dt; gcSpreadSheet1.Invalidate(); private void button1_Click(object sender, RoutedEventArgs e) { gcSpreadSheet1.Sheets[0].ReloadBindingData(); gcSpreadSheet1.Invalidate(); }
