右键单击以选择 dataGridView 中的行 [英] Right click to select row in dataGridView

问题描述

我需要在显示 ContextMenu 之前右键单击 dataGridView 中的一行，因为 contextMenu 依赖于行.

I need to select a row in dataGridView with right click before ContextMenu shown because contextMenu is row-dependendt.

我已经试过了:

 if (e.Button == MouseButtons.Right)
        {

            var hti = dataGrid.HitTest(e.X, e.Y);
            dataGrid.ClearSelection();
            dataGrid.Rows[hti.RowIndex].Selected = true;
        }

或:

private void dataGrid_CellMouseDown(object sender, DataGridViewCellMouseEventArgs e)
    {
        if (e.Button == MouseButtons.Right)
        {
            dataGrid.Rows[e.RowIndex].Selected = true;
            dataGrid.Focus();
        }
    }

这有效，但是当我尝试读取 dataGrid.Rows[CurrentRow.Index] 时，我只看到左键单击选择的行，而不是右键单击选择的行..

This works but when I try to read dataGrid.Rows[CurrentRow.Index] I see only the row selected with left click and not those selected with right click..

推荐答案

尝试像这样设置当前单元格(这将设置 DataGridView 之前的 CurrentRow 属性上下文菜单项被选中):

Try setting the current cell like this (this will set the CurrentRow property of the DataGridView before the context menu item is selected):

    private void dataGridView1_CellMouseDown(object sender, DataGridViewCellMouseEventArgs e)
    {
        var dataGrid = (DataGridView) sender;
        if (e.Button == MouseButtons.Right && e.RowIndex != -1)
        {
            var row = dataGrid.Rows[e.RowIndex];
            dataGrid.CurrentCell = row.Cells[e.ColumnIndex == -1 ? 1 : e.ColumnIndex];
            row.Selected = true;
            dataGrid.Focus();
        }
    }
