Property Value

Type	Description
Int32	The zero-based index of the selected row in the editor’s dropdown. -1 if no row is currently selected, or the data source is not specified.

Remarks

Use the ItemIndex property to select a data item (row) by its visual position in the dropdown.

When initializing the form, call the LookUpEdit.Properties.ForceInitialize method before setting the ItemIndex property. The ForceInitialize method forces the lookup to initialize.

public Form1() {
    InitializeComponent();
    // Bind the lookupEdit1 control to a data source.
    lookUpEdit1.Properties.DataSource = DataHelper.Load();
    // Forces lookup to initialize.
    lookUpEdit1.Properties.ForceInitialize();
    // Set the selected item to the second item in the list.
    lookUpEdit1.ItemIndex = 1;
}
