如何找出当前屏幕上的DataGridView行？

Question

在我的C#(2010)应用程序中,我在虚拟模式下有一个DataGridView,它拥有数千行.是否有可能找出目前屏幕上的哪些细胞？

Answer 1

public void GetVisibleCells(DataGridView dgv)
    {
        var visibleRowsCount = dgv.DisplayedRowCount(true);
        var firstDisplayedRowIndex = dgv.FirstDisplayedCell.RowIndex;
        var lastvisibleRowIndex = (firstDisplayedRowIndex + visibleRowsCount) - 1;
        for (int rowIndex = firstDisplayedRowIndex; rowIndex <= lastvisibleRowIndex; rowIndex++)
        {
            var cells = dgv.Rows[rowIndex].Cells;
            foreach (DataGridViewCell cell in cells)
            {
                if (cell.Displayed)
                {
                    // This cell is visible...
                    // Your code goes here...
                }
            }
        }
    }

更新:它现在找到可见的单元格.
