// Step 1. Derive a custom column style from DataGridTextBoxColumn

// a) add a ComboBox member

// b) track when the combobox has focus in Enter and Leave events

// c) override Edit to allow the ComboBox to replace the TextBox

// d) override Commit to save the changed data

// Step 2 - Use the combo column style

// Add 1 col with combo style

DataGridComboBoxColumn ComboTextCol = new DataGridComboBoxColumn();

ComboTextCol.MappingName = "custCity";

ComboTextCol.HeaderText = "Customer Address";

ComboTextCol.Width = 100;

ts1.GridColumnStyles.Add(ComboTextCol);

// Step 3 - Additional setup for Combo style

// a) make the row height a little larger to handle minimum combo height

ts1.PreferredRowHeight = ComboTextCol.ColumnComboBox.Height + 3;

// b) Populate the combobox somehow. It is a normal combobox, so whatever...

ComboTextCol.ColumnComboBox.Items.Clear();

ComboTextCol.ColumnComboBox.Items.Add("Chicago");

ComboTextCol.ColumnComboBox.Items.Add("Corvallis");

ComboTextCol.ColumnComboBox.Items.Add("Denver");

ComboTextCol.ColumnComboBox.Items.Add("Great Falls");

ComboTextCol.ColumnComboBox.Items.Add("Kansas City");

ComboTextCol.ColumnComboBox.Items.Add("Los Angeles");

ComboTextCol.ColumnComboBox.Items.Add("Raleigh");

ComboTextCol.ColumnComboBox.Items.Add("Washington");

// c) set the dropdown style of the combo...

ComboTextCol.ColumnComboBox.DropDownStyle = ComboBoxStyle.DropDownList;
