Question

有没有人在LinQ3.5中使用了plexityhide的GTP.NET，因为我尝试根据从asp.net查询中获得的变量给各个单元格着色，如下所示

PilotDataContext pilot = new PilotDataContext();

var schedule = from x in pilot.slot_tbl_Schedules select x;

foreach (var s in schedule)
{
    if (s.AppointmentType == "Repair")
    {
        CellLayout cl = gn.GetCell(0).Layout.Clone() as CellLayout;
        gn.GetCell(0).Layout = cll;
        cl.BackgroundColor = Color.Red;
        cl.SelectedColor = Color.Red; 
    }
    else if (s.AppointmentType == "Service")
    {
        CellLayout cl = gn.GetCell(0).Layout.Clone() as CellLayout;
        gn.GetCell(0).Layout = cl;
        cl.BackgroundColor = Color.Blue;
    }
    else if (s.AppointmentType == "TravelTime")
    {
        CellLayout cl = gn.GetCell(0).Layout.Clone() as CellLayout;
        gn.GetCell(0).Layout = cl;
        cl.BackgroundColor = Color.Green;
    }
    else if (s.AppointmentType == "AnnualLeave")
    {
        CellLayout cl = gn.GetCell(0).Layout.Clone() as CellLayout;
        gn.GetCell(0).Layout = cl;
        cl.BackgroundColor = Color.Yellow;
    }
}

if语句中的语法是他们推荐的语法。有谁能帮上忙吗？

非常感谢

Answer 1

确保设置了CellLayout.BackgroundUse=true。如果不这样做，背景颜色将被忽略。

由于您使用ASP.NET，cellLayouts将生成一个css，因此您必须将新克隆的CellLayouts添加到CellLayouts上的集合中：

Gantt_ASP.Gantt.Grid.CellLayouts.Add(cl)；

Answer 2

Dim cl2 As CellLayout = TryCast(e.GridNode.GetCell(4).Layout.Clone(), CellLayout)

cl2.SelectedColor = Color.Red
cl2.FontColor = Color.Red
cl2.BackgroundColor = Color.Blue
cl2.BackgroundUse = True ' when is true background color change 
e.GridNode.GetCell(4).Layout = cl2

它工作正常...：)
