c#中的DataGridView组合框单元事件

Question

我想在DataGridViewComboBox中的项目发生更改时显示一条消息.我可以通过获取datagridview CellbeginEdit事件和CellEndEdit事件来部分执行它,但这不符合标记.我想要它在组合框选择更改事件中发生.

我谷歌它解决但没有得到适当的帮助.

任何帮助都会得到满足.

Answer 1

使用EditingControlShowing事件

private void grvList_EditingControlShowing(object sender, DataGridViewEditingControlShowingEventArgs e)
        {
             if (grvList.Columns[grvList.CurrentCell.ColumnIndex].Name.Equals("routing_ID"))
                {
                    ComboBox cmbprocess = e.Control as ComboBox;
                    cmbprocess.SelectedIndexChanged += new EventHandler(grvcmbProcess_SelectedIndexChanged);
                }
        }


 private void grvcmbProcess_SelectedIndexChanged(object sender, EventArgs e)
        {
            ComboBox cmbprocess = (ComboBox)sender;
            if (cmbprocess.SelectedValue != null)
            {
               /// Your Code goes here
            }

        }

这只是一个示例程序,用于说明如何执行此操作
