表格颜色 字段颜色 字段背景色

1.在FORM数据源下，覆盖方法displayOption();

2.覆盖数据源的Write()方法:在Super之后写入 GridColours_ds.clearDisplayOption(gridColours);

处出关键地方是:affectedElementsByControl()方法。

public void displayOption(Common _record, FormRowDisplayOption _options)
{
    GridColours  gridColoursLocal = _record;
    ;

    super(_record, _options);

    // If highlight flag is set, then give the entire row a black background/white text
    if (gridColoursLocal.Highlight)  //Highlight是一个字段，当被勾选后显示黄色
    {
        _options.backColor(WinApi::RGB2int(255,255,0)); // Yellow
    }
    else
    {
        if (gridColoursLocal.RequestedDate < systemDateGet() || gridColoursLocal.ConfirmedDate > gridColoursLocal.RequestedDate)
        {
            _options.backColor(WinApi::RGB2int(255,0,0)); // Red
            _options.textColor(WinApi::RGB2int(255,255,255)); // White text

            if (gridColoursLocal.RequestedDate < systemDateGet())
            {
                // Applies only to the RequestedDate field on the grid
                _options.affectedElementsByControl(Grid_RequestedDate.id());  //此处重要; 指定受影响的范围仅是Grid中的列
            }

            if (gridColoursLocal.ConfirmedDate > gridColoursLocal.RequestedDate)
            {
                // Applies only to the RequestedDate field on the grid
                _options.affectedElementsByControl(Grid_ConfirmedDate.id());  //同上，如果没有则会整行都上色
            }
        }
    }
}
