datagridview中的combox在加载时默认选择第一项

Question

如何在dataGridView1 中DataGridViewComboBoxColumn显示默认值？没有选择时，显示默认值

Answer 1

界面初始加载时没有对应的key值，可以通过判断获得value值

Answer 2

DataGridViewComboBoxColumn Column = new DataGridViewComboBoxColumn();            dataGridView1.Columns.Add(Column);            Column.Items.Add("内容1");            Column.Items.Add("内容2");            Column.DefaultCellStyle.NullValue = "内容1";  内容1就为显示的默认值。

Answer 3

List items = new List();            items.Add(new Items { Text = "A", Value = "a" });            items.Add(new Items { Text = "B", Value = "b" });             DataGridViewComboBoxColumn co = this.dataGridView1.Columns[0] as DataGridViewComboBoxColumn;            co.DataSource = items;            co.DisplayMember = "Text";            co.ValueMember = "Value";             this.dataGridView1.Rows.Add(new object[] { "a" });            this.dataGridView1.Rows.Add(new object[] { "b" });

Answer 4

在datagridviewRowdataBound中处理，在combox所在列中找到combox，然后设置combox的selectedindex=0;

Answer 5

DataGridView 中的combox 没有selectedIndex 属性
