好心人帮忙,datagridviewcombobox 问题

[zfs346464261]

最近做项目遇到个问题不知道怎么把datagridview中的combobox列变为可写的
修改readonly属性不管用！
谢谢了

这个还真不知道如何修正
不过你可以自己写一个ComBoxBox列

我的博客里有一篇文章介绍如何自定义列
http://blog.csdn.net/wzuomin/archive/2007/06/15/1653619.aspx

不过这个列是一个下拉树的ComBoBox列，你可以把DataGridViewTreeViewEditingControl从ComBoBox继承，类ComboBoxTreeView就不需要了。呵呵

combobox.add("0","value1")
combobox.add("1","value2")
combobox.selectindx=0

谢谢各位已经解决了这样做就可以了（可输入+选择）：
private void dataGridView1_CellValidating_1(object sender, DataGridViewCellValidatingEventArgs e)
{
if (e.ColumnIndex == 2)
{
DataGridViewComboBoxCell comboBoxColumn = (DataGridViewComboBoxCell)dataGridView1[e.ColumnIndex, e.RowIndex];
if (!comboBoxColumn.Items.Contains(e.FormattedValue))
{
//DataGridViewComboBoxCell.ObjectCollection oc = (DataGridViewComboBoxCell.ObjectCollection)comboBoxColumn.Items.GetEnumerator();
//oc.AddRange(e.FormattedValue);
//comboBoxColumn.Items.Clear();
//comboBoxColumn.Items.Insert(0, e.FormattedValue);
comboBoxColumn.Items.Add(e.FormattedValue);
comboBoxColumn.Value = e.FormattedValue;

}
}

}



void cb_SelectedIndexChanged(object sender, EventArgs e)
{
//MessageBox.Show("Selected index changed");
}

private void dataGridView1_EditingControlShowing(object sender, DataGridViewEditingControlShowingEventArgs e)
{
if (this.dataGridView1.CurrentCellAddress.X == 2)
{
ComboBox cb = e.Control as ComboBox;
if (cb != null)
{
cb.DropDownStyle = ComboBoxStyle.DropDown;
cb.SelectedIndexChanged -= new EventHandler(cb_SelectedIndexChanged);
cb.SelectedIndexChanged += new EventHandler(cb_SelectedIndexChanged);
}
}
}
