当DatagridviewComboBox选择索引更改时，更改DatagridviewTextBox文本 [英] Change DatagridviewTextBox Text When DatagridviewComboBox Selected Index Changes

问题描述

在我的 DatagridView 中，我有两个列， ComboxboxColumn 和 TextboxColumn 。当组合框选择索引更改时，我想更改文本框
的值（一般来说，组合框已经选择了索引更改事件，但 datagridviewComboBox 没有）

In My DatagridView,I Have Two Columns, ComboxboxColumn and TextboxColumn. I want to change the value of textbox when combobox selected index changes (in general combobox it has selected index change event but datagridviewComboBox does not have it)

推荐答案

给出这两个简单的方法（顶部方法中的'1'是组合框列的索引）

Give these two simple methods a go (the '1' in the top method is the index of the combobox column)

您将使您修改的行将是setter行 cel.Value = ，因为您可能会将其更改为任何你喜欢。

The line that you would make you modifications to would be the setter line cel.Value =, as you may change it to whatever you like.

    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();
    }
