我的意思是datagridview 换单元格会触发此事件.我想知道他进入了那个单元格.

currentrow能用吗？

//这个是定位那一列
this.xfdgCode_DefRuleDtl.Columns[e.ColumnIndex].Name.ToString().Equals("ItemLenght")
//这个是定位那4行的那一列的值
this.xfdgCode_DefRuleDtl[4, e.RowIndex].Value.Equals("流水码")
看看应该明白吧！

MouseEnter事件只在鼠标穿越DataGridView的边界时才发生，确切的说是即将进入时，所以在这个事件发生时鼠标哪个Cell也不位于！！！！

你一定要在DataGridView的MouseEnter来判断Cell吗，其实你可以用DataGridView的CellMouseEnter事件，事件参数DataGridViewCellEventArgs可以获得进入单元格的所在行及列的索引值，大致代码如下：

        private void dataGridView1_CellMouseEnter(object sender, DataGridViewCellEventArgs e)

        {

            DataGridViewCell enterCell = dataGridView1.Rows[e.RowIndex].Cells[e.ColumnIndex];

        }

我用 CellEndEdit
