在BCB中我用了一控件TdxDBGrid, (Dev Express) 怎樣做到交替行背景色?

如題!

和DBGrid差不多吧

void __fastcall TForm1::DBGrid1DrawColumnCell(TObject *Sender,
const TRect &Rect, int DataCol, TColumn *Column,
TGridDrawState State)
{
if(Column->Field->DataSet->RecNo%2)
{
((TDBGrid *)Sender)->Canvas->Font->Color=clWindowText;
((TDBGrid *)Sender)->Canvas->Brush->Color=(TColor)RGB(229,236,249);
if (State.Contains(gdSelected) || State.Contains(gdFocused))
{
((TDBGrid *)Sender)->Canvas->Font->Color=clHighlightText;
((TDBGrid *)Sender)->Canvas->Brush->Color=clHighlight;
}
}
((TDBGrid *)Sender)->DefaultDrawColumnCell(Rect,DataCol,Column,State);
}

与DBGrid不一样的，应该如此：
void __fastcall TForm1::dxDBGrid1CustomDrawCell(TObject *Sender,
TCanvas *ACanvas, TRect &ARect, TdxTreeListNode *ANode,
TdxTreeListColumn *AColumn, bool ASelected, bool AFocused,
bool ANewItemRow, AnsiString &AText, TColor &AColor, TFont *AFont,
TAlignment &AAlignment, bool &ADone)
{
if (ASelected) return;
if(ANode->Index%2) AColor =0x00D8D9C0; //或者在此处判断RecNo的奇偶
else AColor = 0x00DBFBFD;
}
