问题描述

我有一个datagridview由多行和列组成。
我想遍历每一行并检查特定列的内容。
如果该列包含单词否,我想将整行的前缀更改为红色。
这是到目前为止的一些代码尝试,但它肯定不起作用,开始想知道如果我需要迭代每个单元格?



代码: p>

  foreach(dataGridView1.Rows中的DataGridViewRow dgvr)
{
if(dgvr.Cells [FollowedUp] .Value.ToString()==(否))
{
dgvr.DefaultCellStyle.ForeColor = Color.Red;
}
}


解决方案

  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()。包含(否))
{
dgvr.DefaultCellStyle = RedCellStyle;
}
if(dgvr.Cells [FollowedUp]。Value.ToString()。Contains(Yes))
{
dgvr.DefaultCellStyle = GreenCellStyle;
}
}
}


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?

CODE:

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

解决方案

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;
            }
        }
    }
