How to: Change Item's Height in ComboBoxEdit
The following example shows how to set a custom height for items in a ComboBoxEdit control by handling the RepositoryItemComboBox.MeasureItem event.
In this example, if a specific item contains a NewLine character (“\r\n” in C#), its height is doubled to fully display the item’s text.
using DevExpress.XtraEditors;
private void comboBoxEdit1_Properties_MeasureItem(object sender, MeasureItemEventArgs e) {
ComboBoxEdit cb = sender as ComboBoxEdit;
string itemValue = (string)cb.Properties.Items[e.Index];
if (itemValue.Contains("\r\n"))
e.ItemHeight = e.ItemHeight * 2;
}
