我想要更改DGV的行的背景颜色基于特定的条件,即使在
Windows窗体中的负载.但是,我看不到任何DGV行的颜色有任何改变.有人可以告诉我如何解决这个问题？
private void frmSecondaryPumps_Load(object sender,EventArgs e)
{
try
{
DataTable dt = DeviceData.BindData("SECONDARY_PUMPS".ToUpper());
dataGridView1.DataSource = dt;
foreach (DataGridViewRow row in dataGridView1.Rows)
{
foreach (DataGridViewColumn column in dataGridView1.Columns)
{
if (row.Cells[column.Name] != null)
{
if (row.Cells[column.Name].Value.ToString() == "ON")
row.DefaultCellStyle.BackColor = System.Drawing.Color.Green;
if (row.Cells[column.Name].Value.ToString() == "OFF")
row.DefaultCellStyle.BackColor = System.Drawing.Color.Red;
}
}
}
dataGridView1.Refresh();
}
catch (Exception err)
{
MessageBox.Show(err.Message);
}
}
解决方法
我认为最好的办法是在DataGridView的CellFormatting事件中设置BackColor,这些都是这些.
private void grid1_CellFormatting(object sender,DataGridViewCellFormattingEventArgs e)
{
DataGridViewRow row = grid1.Rows[e.RowIndex];// get you required index
// check the cell value under your specific column and then you can toggle your colors
row.DefaultCellStyle.BackColor = Color.Green;
}
