Examples

The following code example demonstrates how to use a DataGridViewComboBoxColumn to aid in entering data into the TitleOfCourtesy column. The Items property is used to populate the combo box drop-down list with a selection of titles. This example is part of a larger example available in the DataGridViewComboBoxColumn class overview topic.

private:
    void SetAlternateChoicesUsingItems(
        DataGridViewComboBoxColumn^ comboboxColumn)
    {
        comboboxColumn->Items->AddRange("Mr.", "Ms.", "Mrs.", "Dr.");
    }

private:
    DataGridViewComboBoxColumn^ CreateComboBoxColumn()
    {
        DataGridViewComboBoxColumn^ column =
            gcnew DataGridViewComboBoxColumn();
        {
            column->DataPropertyName = ColumnName::TitleOfCourtesy.ToString();
            column->HeaderText = ColumnName::TitleOfCourtesy.ToString();
            column->DropDownWidth = 160;
            column->Width = 90;
            column->MaxDropDownItems = 3;
            column->FlatStyle = FlatStyle::Flat;
        }
        return column;
    }

private static void SetAlternateChoicesUsingItems(
    DataGridViewComboBoxColumn comboboxColumn)
{
    comboboxColumn.Items.AddRange("Mr.", "Ms.", "Mrs.", "Dr.");
}

private DataGridViewComboBoxColumn CreateComboBoxColumn()
{
    DataGridViewComboBoxColumn column =
        new DataGridViewComboBoxColumn();
    {
        column.DataPropertyName = ColumnName.TitleOfCourtesy.ToString();
        column.HeaderText = ColumnName.TitleOfCourtesy.ToString();
        column.DropDownWidth = 160;
        column.Width = 90;
        column.MaxDropDownItems = 3;
        column.FlatStyle = FlatStyle.Flat;
    }
    return column;
}

Private Shared Sub SetAlternateChoicesUsingItems( _
    ByVal comboboxColumn As DataGridViewComboBoxColumn)

    comboboxColumn.Items.AddRange("Mr.", "Ms.", "Mrs.", "Dr.")

End Sub

Private Function CreateComboBoxColumn() _
    As DataGridViewComboBoxColumn
    Dim column As New DataGridViewComboBoxColumn()

    With column
        .DataPropertyName = ColumnName.TitleOfCourtesy.ToString()
        .HeaderText = ColumnName.TitleOfCourtesy.ToString()
        .DropDownWidth = 160
        .Width = 90
        .MaxDropDownItems = 3
        .FlatStyle = FlatStyle.Flat
    End With
    Return column
End Function

Remarks

This property returns the value of the Items property of the DataGridViewComboBoxCell returned by the CellTemplate property.

The Items or DataSource properties are used to populate the selections of the combo boxes.

If strings are added to Items, then the ValueMember and DisplayMember properties do not need to be set because each string added will be used for both value and display.

If the DataSource property is set, then Items cannot be used.
