Property Value

An object that implements the IList interface, such as a DataSet or an Array. The default is a null reference (Nothing in Visual Basic).

A data source can be a database, a Web service, or an object that can later be used to generate data-bound controls. When the DataSource property is set, the items collection cannot be modified.

The following example uses the DataSource property to get values for menu merging. This example is part of a larger example available in the ToolStripManager class overview.

// This ComboBox allows the user to switch between the samples.
ComboBox sampleSelectorCombo = new ComboBox();
sampleSelectorCombo.DataSource = Enum.GetValues(typeof(MergeSample));
sampleSelectorCombo.SelectedIndexChanged += new EventHandler(comboBox_SelectedIndexChanged);
sampleSelectorCombo.Dock = DockStyle.Top;
