问题描述

我有一个由多行多列组成的数据网格视图.我想遍历每一行并检查特定列的内容.如果该列包含单词NO",我想将整行的前景色更改为红色.到目前为止,这是对一些代码的尝试,但它肯定不起作用,开始怀疑是否需要迭代每个单元格?

I have a datagridview made up of multiple rows and columns. I want to iterate through each row and check the contents of a specific column. If that column contains the word "NO", I want to change the forecolor of the entire row to Red. Here is an attempt at some code so far but It's certainly not working, starting to wonder If I need to iterate over every cell?

代码:

foreach (DataGridViewRow dgvr in dataGridView1.Rows)
        {
            if (dgvr.Cells["FollowedUp"].Value.ToString() == ("No"))
            {
                dgvr.DefaultCellStyle.ForeColor = Color.Red;
            }
        }

推荐答案

public void ColourChange()
    {
        DataGridViewCellStyle RedCellStyle = null;
        RedCellStyle = new DataGridViewCellStyle();
        RedCellStyle.ForeColor = Color.Red;
        DataGridViewCellStyle GreenCellStyle = null;
        GreenCellStyle = new DataGridViewCellStyle();
        GreenCellStyle.ForeColor = Color.Green;


        foreach (DataGridViewRow dgvr in dataGridView1.Rows)
        {
            if (dgvr.Cells["FollowedUp"].Value.ToString().Contains("No"))
            {
                dgvr.DefaultCellStyle = RedCellStyle;
            }
            if (dgvr.Cells["FollowedUp"].Value.ToString().Contains("Yes"))
            {
                dgvr.DefaultCellStyle = GreenCellStyle;
            }
        }
    }
