After the imagecollection can add pictures, but virtualimagelist1 cannot be loaded dynamically, but when it is added manually, the bound pictures can be displayed, and the dynamic loading cannot be displayed，

 

procedure TForm2.Button1Click(Sender: TObject);
begin
    ImageCollection2.Add('1','D:\pict\1.png');
    ImageCollection2.Add('2','D:\pict\2.png');
     ImageCollection2.Add('3','D:\pict\2.png');
    VirtualImageList1.ImageCollection:=ImageCollection1;
    VirtualImageList1.UpdateImageList;
end;

Check out the AutoFill property of the VirtualImageList. It should be true in order to load all the images from the image collection.

查看 VirtualImageList 的 AutoFill 属性。为了从图像集合中加载所有图像，它应该是正确的。 

 

VirtualImageList .autofill:=true  , because when it is added manually, the bound pictures can be displayed ，After the imagecollection can add pictures, but virtualimagelist1 cannot be loaded dynamically,

// Resolved the synchronization issue by resetting the ImageCollection of VirtualImageList1.
VirtualImageList1.ImageCollection := nil;
