c# 如何在datagridview中实现下拉列表可变的联动combobox

Answer 1

private void datagridView_EditingControlShowing(object sender, DataGridViewEditingControlShowingEventArgs e)
        {
            DataGridView dataGridView = (DataGridView)sender;
            if(dataGridView.CurrentCell.OwningColumn.Name == "yourCombobox")
            {
                        ComboBox comboBox = (ComboBox)e.Control;
                        comboBox.SelectedIndexChanged += new EventHandler(comboBox_SelectedIndexChanged);
            }
}

 void comboBox_SelectedIndexChanged(object sender, EventArgs e)
 {
   银芹         ComboBox comboBox = (ComboBox)sender;
            if (dataGridView.CurrentCell.OwningColumn.Name == "yourCombobox")
            {
                if (comboBox.Text != "")
                {  
                    this.SendComboBoxDataSource.DataSource = query(comboBox.Text);
                }
            }
 }

 首先通过这个埋正EditingControlShowing事件响应，为第一弯搏悔个ComboBox添加一个SelectedIndexChanged的事件，在SelectedIndexChanged事件中，绑定第二个ComboBox的数据源。大致思路是这样，仅供参考。
