怎么给在datagridview里面的DataGridViewComboBoxColumn设置SelectedIndexChanged事件？

Question

如题哦。

Answer 1

//在datagridview的Editing事件里面写
private void dataGridView_EditingControlShowing(object sender, DataGridViewEditingControlShowingEventArgs e)
{
    ComboBox cb = e.Control as ComboBox;
    if (cb != null)
    {
        cb.SelectedIndexChanged += new EventHandler(cb_SelectedIndexChanged);
    }
}
void cb_SelectedIndexChanged(object sender, EventArgs e)
{
     //这里执行你需要的,这就是下拉事件
}

Answer 2

一个datagridview里面有多个combobox的列，我只有其中column1的有这样的事件，请问一下语句中哪里是绑到到对应的datagridview和对应的列?谢谢

Answer 3

 //在dataGridView_EditingControlShowing时间里面判断要处理的DataGridViewComboBoxColumn名称，若符合条件，编辑控件被强制转换为ComboBox以处理，添加SelectedIndexChanged事件
            if (this.dataGridView.CurrentCell.OwningColumn.Name == "DataGridViewComboBoxColumn名称")
            {
                ((ComboBox)e.Control).SelectedIndexChanged += new EventHandler(ComboBox_SelectedIndexChanged);
            }

Answer 4

     private void dataGridView_EditingControlShowing(object sender, DataGridViewEditingControlShowingEventArgs e)
        {
         
            if (this.dataGridView2.CurrentCell.OwningColumn.Name == "Column2")
            {
                ((ComboBox)e.Control).SelectedIndexChanged += new EventHandler(Column2_SelectedIndexChanged);
            }
        }
     
        void Column2_SelectedIndexChanged(object sender, EventArgs e)
        {
            MessageBox.Show("??");
        }我这样写没有效果哦
