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

Question

在我的DatagridView，我有两列，ComboxboxColumn和TextboxColumn。我想在组合框选定索引更改时更改文本框的值（通常组合框已选择索引更改事件但datagridviewComboBox没有它）

Answer 1

试试这两个简单的方法（顶部方法中的 '1' 是组合框列的索引）

您要修改的行将是 setter line cel.Value =，因为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();
    }
