DataGridViewColumn.ValueType Property
.NET Framework 4
Gets or sets the data type of the values in the column's cells.
Assembly: System.Windows.Forms (in System.Windows.Forms.dll)
The following code example demonstrates how to use the ValueType property in the initialization of a DataGridViewComboBoxColumn that contains Color values.
private DataGridView dataGridView1 = new DataGridView(); private void AddColorColumn() { DataGridViewComboBoxColumn comboBoxColumn = new DataGridViewComboBoxColumn(); comboBoxColumn.Items.AddRange( Color.Red, Color.Yellow, Color.Green, Color.Blue); comboBoxColumn.ValueType = typeof(Color); dataGridView1.Columns.Add(comboBoxColumn); dataGridView1.EditingControlShowing += new DataGridViewEditingControlShowingEventHandler( dataGridView1_EditingControlShowing); } private void dataGridView1_EditingControlShowing(object sender, DataGridViewEditingControlShowingEventArgs e) { ComboBox combo = e.Control as ComboBox; if (combo != null) { // Remove an existing event-handler, if present, to avoid // adding multiple handlers when the editing control is reused. combo.SelectedIndexChanged -= new EventHandler(ComboBox_SelectedIndexChanged); // Add the event handler. combo.SelectedIndexChanged += new EventHandler(ComboBox_SelectedIndexChanged); } } private void ComboBox_SelectedIndexChanged(object sender, EventArgs e) { ((ComboBox)sender).BackColor = (Color)((ComboBox)sender).SelectedItem; }
