推荐答案

使用 DataGridView.RowPrePaint事件 [ ^ ] - 在绘制整行之前调用它，并允许您设置适当的单元格样式属性，无论你需要什么。



拼写错误[/ edit]

Use the DataGridView.RowPrePaint event[^] - it's called just before the whole row is painted, and allows you to set the appropriate cell Style property to whatever you need.

如果它是一个窗口表单项目您可以使用以下内容：



在设计器中添加int以订阅Cell end edit事件：

If it is a windows form project you can use the following:

Add int the designer the next line to subscribe to the Cell end edit event:

this.dataGridView1.CellEndEdit += new System.Windows.Forms.DataGridViewCellEventHandler(this.dataGridView1_CellEndEdit);

在事件处理程序中，您验证字符串：

And in the event handler you verify with you string:

private static const string yourString = "XYZ";

private void dataGridView1_CellEndEdit(object sender, DataGridViewCellEventArgs e)
{
    DataGridView dataGridView = (DataGridView)sender;

    if (dataGridView.CurrentCell.Value.ToString() == yourString)
    {
        dataGridView.CurrentCell.Style.ForeColor = Color.Red;
    }

}

您可以通过全部验证重复项单元格：

You can verify for duplicates by going thru all the cells:

private void dataGridView1_CellEndEdit(object sender, DataGridViewCellEventArgs e)
{
    DataGridView dataGridView = (DataGridView)sender;

    // Iterate thru all the cell and verifying if the text is a duplicate.
    for (int i = 0; i < dataGridView.ColumnCount; i++)
    {
        for (int j = 0; j < dataGridView.RowCount; j++)
        {
            if (dataGridView.Rows[j].Cells[i].Value != null)
            {
                if (dataGridView.Rows[j].Cells[i].Value.ToString() == dataGridView.CurrentCell.Value.ToString() && dataGridView.Rows[j].Cells[i] != dataGridView.CurrentCell)
                {
                    dataGridView.CurrentCell.Style.ForeColor = Color.Red;

                    // Optional you can set the value of the cell where you find the text
                    dataGridView.Rows[j].Cells[i].Style.ForeColor = Color.Red;

                }
            }
        }
    }
}
