右击datagridview如何判断是否点到某单元格并获取其位置显示右键菜单

Question

小弟初学C# 最近做个东西 要用到datagridview 所以来着问下大家这该怎么弄呃？

Answer 1

datagridview有cellclick事件可以给你判断是否点到单元格，点到了就会触发，至于右键菜单，你可以添加上下文菜单控件，然后显示这个控件

Answer 2

代码来自http://bingning.net/free/source/datagridview/currentcell.html

取得当前单元格的代码。Console.WriteLine("现在单元格的位置是({0}, {1})。",
     DataGridView1.CurrentCellAddress.X,
     DataGridView1.CurrentCellAddress.Y);
菜单设定的代码//DataGridView的ContextMenuStrip设定
 DataGridView1.ContextMenuStrip = this.ContextMenuStrip1; //列的ContextMenuStrip设定
 DataGridView1.Columns[0].ContextMenuStrip = this.ContextMenuStrip2;
 //列Header的ContextMenuStrip设定
 DataGridView1.Columns[0].HeaderCell.ContextMenuStrip = this.ContextMenuStrip2; //行的ContextMenuStrip设定
 DataGridView1.Rows[0].ContextMenuStrip = this.ContextMenuStrip3; //单元格的ContextMenuStrip设定
 DataGridView1[0, 1].ContextMenuStrip = this.ContextMenuStrip4;

Answer 3

 private void dataGridView1_MouseDown(object sender, MouseEventArgs e)
        {
            DataGridView.HitTestInfo info = this.dataGridView1.HitTest(e.Location.X, e.Location.Y);
           // info中有相关的信息.
        }

Answer 4

 private void dataGridView1_CellMouseDown(object sender, DataGridViewCellMouseEventArgs e)
        {
            if (e.Button == MouseButtons.Right)
            {
                if (e.RowIndex >= 0)
                {
                    dataGridView1.ClearSelection();
                    dataGridView1.Rows[e.RowIndex].Selected = true;
                    dataGridView1.CurrentCell = dataGridView1.Rows[e.RowIndex].Cells[e.ColumnIndex];
                    cm_col.Show(MousePosition.X, MousePosition.Y);
                }
            }
