C# DataGridView控件 修改一行或单元格的颜色

1.winform datagridview更改选中行中选中单元格的背景或字体颜色

private void dataGridView1_CellClick(object sender, DataGridViewCellEventArgs e)
{
            if (dataGridView1.Rows[e.RowIndex].Cells[e.ColumnIndex].Selected)
            {
                DataGridViewCell aa = dataGridView1.Rows[e.RowIndex].Cells[e.ColumnIndex];
                aa.Style.ForeColor = Color.Red;
                aa.Style.BackColor = Color.LightGreen;
            }
}

2.winfrom——DataGridView 选中某一行的事件

先将SelectionMode属性设置一下，改为fullrowselection. 然后给一个cellclick事件 注意：点击表头时也会触发此事件，在取值时要排除

private void dataGridView2_CellClick(object sender, DataGridViewCellEventArgs e)
{
　　//当点击表头部的列时，e.RowIndex==-1
　　if (e.RowIndex > -1)
　　{
　　　　this.txtUsername.Text = this.dataGridView2.Rows[e.RowIndex].Cells[1].Value.ToString();
　　　　this.txtPassword.Text = this.dataGridView2.Rows[e.RowIndex].Cells[2].Value.ToString();
　　　　this.txtPosition.Text = this.dataGridView2.Rows[e.RowIndex].Cells[3].Value.ToString();
　　　　this.txtStatus.Text = this.dataGridView2.Rows[e.RowIndex].Cells[6].Value.ToString();
　　　　this.txtName.Text = this.dataGridView2.Rows[e.RowIndex].Cells[7].Value.ToString();
　　}
 
}

3.C#控件DataGridView通过一列的值改变整行颜色

在控件DataGridView的RowPrePaint事件：

 private void DGV_staffList_RowPrePaint(object sender, DataGridViewRowPrePaintEventArgs e)
        {
           
            for (int i = 0; i < this.DGV_staffList.Rows.Count; i++)
            {
                if (this.DGV_staffList.Rows[i].Cells["Column14"].Value.ToString() == "1")
                {
                    this.DGV_staffList.Rows[i].DefaultCellStyle.ForeColor = Color.Red;
                }
 
            }
 
        }
