本文介绍了一种通过设置TableController的LeftPos和TopRowIndex属性来实现Grid程序化滚动的方法。LeftPos定义了水平滚动条的位置（以像素为单位），而TopRowIndex定义了顶部行的索引。只需设置这些属性值即可实现滚动。

To scroll the Grid programmatically, you should set the following Table Controller's properties:

1) LeftPos
2) TopRowIndex;

Please note, the first property defines the position of the horizontal scrollbar in pixels. The second one defines the index of the top row index. So, the horizontal scrollbar can be scrolled by one pixel whilst the vertical one can be scrolled based on the height of a certain row. All you need to do is to set these properties values:

[Delphi]

<aView>.Controller.LeftPost := 25; <aView>.Controller.TopRowIndex := <aView>.Controller.TopRowIndex + 1;
