c# - DatagridviewComboBox 选定索引更改时更改 DatagridviewTextBox 文本

Question

在我的 DatagridView 中，我有两列，ComboxboxColumn 和 TextboxColumn。我想改变文本框的值当组合框选择索引更改时(一般组合框它选择索引更改事件但 datagridviewComboBox 没有它)

Answer 1

试一试这两个简单的方法(顶部方法中的“1”是组合框列的索引)

您要对其进行修改的行是 setter 行 cel.Value =，您可以将其更改为您喜欢的任何内容。

    private void dataGridView1_EditingControlShowing(object sender, DataGridViewEditingControlShowingEventArgs e)
    {
        if (dataGridView1.CurrentCell.ColumnIndex == 1 && e.Control is ComboBox)
        {
            ComboBox comboBox = e.Control as ComboBox;
            comboBox.SelectedIndexChanged += LastColumnComboSelectionChanged;
        }
    }

    private void LastColumnComboSelectionChanged(object sender, EventArgs e)
    {
        var currentcell = dataGridView1.CurrentCellAddress;
        var sendingCB = sender as DataGridViewComboBoxEditingControl;
        DataGridViewTextBoxCell cel = (DataGridViewTextBoxCell)dataGridView1.Rows[currentcell.Y].Cells[0];
        cel.Value = sendingCB.EditingControlFormattedValue.ToString();
    }
