改变datagridview的单元格颜色动态 [英] Changing datagridview cell color dynamically

问题描述

我有一个用数据填充一个DataGridView对象。我想点击一个按钮，把它改变细胞的背景颜色。这是我目前有

I have a dataGridView object that is populated with data. I want to click a button and have it change the color of the background of the cell. This is what I currently have

foreach(DataGridViewRow row in dataGridView1.Rows)
{
    foreach(DataGridViewColumn col in dataGridView1.Columns)
    {
            //row.Cells[col.Index].Style.BackColor = Color.Green; //doesn't work
            //col.Cells[row.Index].Style.BackColor = Color.Green; //doesn't work
        dataGridView1[col.Index, row.Index].Style.BackColor = Color.Green; //doesn't work
    }
} 

这三个原因表格以重叠的方式被重画在其自身上，并试图重新大小的表变得一团糟。在一个单元格，当点击，值保持高亮显示，背景色不会改变。

ALL of these three cause the table to be redrawn over itself in an overlapping manner and trying to re-size the tables becomes a mess. when clicking on a cell, the value remains highlighted and the backcolor doesn't change.

问：我怎样才能更改单个单元格的背景色表中存在之后

Q: How can I change the backcolor of an individual cell after the table exists?
