获取新的值或指数与DataGridView的组合框的SelectionChangeCommitted事件

问题描述

IM使用SelectionChangeCommitted当一个组合框选定的索引改为赶上事件，但我无法得到它的新的价值或索引。

 私人无效ruleList_EditingControlShowing（对象发件人，DataGridViewEditingControlShowingEventArgs E）
 {
如果（e.Control是组合框）
 {
组合框下拉框中= e.Control作为组合框; 
 comboBox.SelectionChangeCommitted + = ruleListColumnComboSelectionChanged; 
} 
} 
 
私人无效ruleListColumnComboSelectionChanged（对象发件人，EventArgs五）
 {
字符串值= ruleList.CurrentCell.Value.ToString（）; //之前更改
} 
  

解决方案

您可以用得到的新值：

 组合框下拉框中= sender.Control作为组合框; 
 MessageBox.Show（comboBox.Text）; 
  

im using SelectionChangeCommitted to catch the event when a combobox selected index changed, but I can not get it's new value or index.

private void ruleList_EditingControlShowing(object sender, DataGridViewEditingControlShowingEventArgs e)
    {
        if (e.Control is ComboBox)
        {
            ComboBox comboBox = e.Control as ComboBox;
            comboBox.SelectionChangeCommitted += ruleListColumnComboSelectionChanged;
        }
    }

    private void ruleListColumnComboSelectionChanged(object sender, EventArgs e)
    {
        string value = ruleList.CurrentCell.Value.ToString(); // just return the old value before the change
    }

解决方案

You can get the new Value using:

ComboBox comboBox = sender.Control as ComboBox;
MessageBox.Show(comboBox.Text);
