使用gridview的CustomDrawCell事件。
private void gridview_CustomDrawCell(object sender, DevExpress.XtraGrid.Views.Base.RowCellCustomDrawEventArgs e)
{
//assume colMaxRate is your Max Rate column name
if (e.Column.FieldName == colMaxRate.FieldName) {
//do your calculation you need, in this example, find max value of next 4 rows including current row
int maxValue = 0;
//initialize maxValue to current row’s value
maxValue = gridview.GetRowCellValue(e.RowHandle, colRate.FieldName);
for (rowIndex = 0; rowIndex < 4; rowIndex++) {
//TODO: do your own checking to make sure you don’t exceed last row count
if (maxValue > gridview.GetRowCellValue(e.RowHandle + rowIndex, colRate.FieldName)) {
maxValue = gridview.GetRowCellValue(e.RowHandle + rowIndex, colRate.FieldName);
}
}
e.DisplayText = maxValue.ToString();
e.Handled = true;
}
}</code>
