滚动后，C ++ Builder DrawGrid InsertControl无法正确重绘

Question

我正在尝试向drawgrid添加多个控件。我可以添加控件，但在添加它们并滚动之后，控件会在不同的单元格中绘制。

这是我用来将控件添加到drawgrid的代码：

void __fastcall TForm1 :: Button1Click（TObject * Sender） {

pnlHierBox = new TPanel（this）; //在班级定义

pnlHierBox->Left = 0;
pnlHierBox->Top = 0;
pnlHierBox->Width = 180;
pnlHierBox->Height = 120;

img = new TImage(pnlHierBox);
img->Picture = Image1->Picture;
img->Left = 0;
img->Top = 3;
img->AutoSize = true;
img->Parent = pnlHierBox;

     lbl = new TLabel(pnlHierBox);
lbl->Caption = "Employee 1";
lbl->Left = 24;
lbl->Top= 15;
lbl->Parent = pnlHierBox;

icon = new TImage(pnlHierBox);
icon->Picture = Image2->Picture;
icon->Left = 100
icon->Top = 63;
icon->AutoSize = true;

icon->Parent = pnlHierBox;
rect = DrawGrid1->CellRect(2,0);
     pnlHierBox->Top = rect.Top;
     pnlHierBox->Left = rect.Left;

     DrawGrid1->InsertControl(pnlHierBox);

//将其他TPanel控件添加到drawgrid中 //

}

Answer 1

请勿直接致电InsertControl()。请改用Parent属性：

// DrawGrid1->InsertControl(pnlHierBox);
pnlHierBox->Parent = DrawGrid1;
