问题描述
我已将数据从数据库加载到 datagridview 并有两列目标值和体积,其中体积 > 目标值,体积单元格应为绿色,体积 <目标值则音量应为红色.我试过了,但我做不到.
I have loaded the data from database to datagridview and have two columns target value and volume where volume >target value that volume cell should be in green color and volume < target value then volume should be in red color. I tried it but I am not able to do it.
private void dataGridView1_DataBindingComplete(object sender, DataGridViewBindingCompleteEventArgs e)
{
if (dataGridView1.Rows.Count > 0 && dataGridView1.Columns.Count > 0)
{
foreach (DataGridViewRow r in dataGridView1.Rows)
{
if (Volume > target value)
{
cell.Style.BackColor = Color.AliceBlue;
}
推荐答案
你需要这样做
private void dataGridView1_CellFormatting(object sender, DataGridViewCellFormattingEventArgs e)
{
foreach (DataGridViewRow Myrow in dataGridView1.Rows)
{ //Here 2 cell is target value and 1 cell is Volume
if (Convert.ToInt32(Myrow .Cells[2].Value)<Convert.ToInt32(Myrow .Cells[1].Value))// Or your condition
{
Myrow .DefaultCellStyle.BackColor = Color.Red;
}
else
{
Myrow .DefaultCellStyle.BackColor = Color.Green;
}
}
}
同时也看看 Cell Formatting
