如何在datagridview中突出显示单元格？ [英] How can i highlight the cell in datagridview?

问题描述

我正在创建一个包含datagridview的小应用程序，此gridview由文本文件填充。现在，如果我在任何单元格中进行了一些更改或添加了一些新单元格，那么它应该以某种颜色突出显示，直到我不保存此更改。

我使用了

I am creating a small application that contains a datagridview and this gridview is filled by text file. Now If I made some changes in any cell or add some new cells then it should be highlighted by some color untill I am not save this changes.
I have used the

dataGridView1_CellValidating

事件，它运行正常。但问题是，一旦我更改了单元格的值，它就会突出显示，但如果我恢复原始值，它仍然会保持突出显示不应该。

我使用以下代码进行比较：

event and it works fine. but the problem is that once I changed the value of cell it gets highlighted but if I restore the original value it still remains highlighted that should not.
I have use following code for comparing:

 private void dataGridView1_CellValidating(object sender, DataGridViewCellValidatingEventArgs e)
        {
            foreach (DataGridViewRow row in dataGridView1.Rows)
            {
                foreach (DataGridViewCell cell in row.Cells)
                {
                    var oldValue = dataGridView1[e.ColumnIndex, e.RowIndex].Value;
                    var newValue = e.FormattedValue;
                    if (oldValue != newValue)
                    {
                        dataGridView1.Rows[e.RowIndex].Cells[e.ColumnIndex].Style.BackColor = System.Drawing.Color.LightPink;
                    }
                }
            }
}

推荐答案

使用DataGridViewCell.Tag属性 - 将其设置为 bool 值，并在 DataGridView.CellPainting Event（System.Windows.Forms） [ ^ ] - 如果是真的，它会改变，需要一个不同的背景或你选择的任何东西。

Use the DataGridViewCell.Tag property - set it to a bool value and check it in the DataGridView.CellPainting Event (System.Windows.Forms)[^] - if it's true, it's changed and needs a different background or whatever you choose.
