This recipe shows you how to populate a UITableView with rows of data.


A table in iOS requires both a UITableView to present the data and a UITableViewSource to supply to the data.

To create and populate a table:

  • First create a UITableView instance and add it to a view (see the HomeScreen.cs ViewDidLoad method in the sample):
table = new UITableView(View.Bounds);
Add (table);
  • Create a subclass of UITableViewSource that accepts an array of strings. Override the RowsInSection and GetCell methods as shown (in the TableSource.cs sample file):
public class TableSource : UITableViewSource {
    protected string[] tableItems;
    protected string cellIdentifier = "TableCell";
    public TableSource (string[] items)
        tableItems = items;
    public override int RowsInSection (UITableView tableview, int section)
        return tableItems.Length;
    public override UITableViewCell GetCell (UITableView tableView, NSIndexPath indexPath)
        // request a recycled cell to save memory
        UITableViewCell cell = tableView.DequeueReusableCell (cellIdentifier);
        // if there are no cells to reuse, create a new one
        if (cell == null)
            cell = new UITableViewCell (UITableViewCellStyle.Default, cellIdentifier);
        cell.TextLabel.Text = tableItems[indexPath.Row];
        return cell;
  • Create an array of strings:
string[] tableItems = new string[] {"Vegetables","Fruits","Flower Buds","Legumes","Bulbs","Tubers"};
  • Instantiate the UITableViewSource with the array, and set the Source property on the table.
table.Source = new TableSource(tableItems);
  • The table will be displayed.

Additional Information

The steps above only display a table, it does not accept user input. To show an alert when the user touches a row, refer to the recipe Handle a Row Click.
