统计datagridview行数

[wangs_1]

1.datagridview.Rows.Count ,可以统计行数，但是也会包括被隐藏的，我问一下在统计行数的时候，如何能过滤掉隐藏行？

2.复制datagridview单元格内容，会复制出这一行的数据，如何只复制选中单元格的内容？

/// <summary>

    /// 计算GridView中的记录数

    /// </summary>

    /// <param name="gv">GridView的实例</param>

    /// <returns></returns>

    static public int GetRecordCount(GridView gv)

    {

        // 不分页，或只有1页，则取当前页的行数

        if (!gv.AllowPaging || gv.PageCount <= 1)

            return gv.Rows.Count;

 

        // 记录当前页索引，以便计算完成后恢复

        int nCurPage = gv.PageIndex;

 

        // 跳转到最后一页

        gv.PageIndex = gv.PageCount - 1;

        gv.DataBind();

 

        // 计算总行数，为：(总页数 - 1) * 每页行数 + 最后一页行数

        int nTotalCount = gv.PageIndex * gv.PageSize + gv.Rows.Count;

 

        // 恢复原页索引

        gv.PageIndex = nCurPage;

        gv.DataBind();

 

        // 返回计算出的页数

        return nTotalCount;

}

JS 要不然隐藏的时候 改变个值 每隐藏一次 自加1 最后COUNT减去这个数

                Clipboard.SetDataObject(
                    this.DataGridView1.GetClipboardContent());
                
                // Replace the text box contents with the clipboard text.
                this.TextBox1.Text = Clipboard.GetText();
            }
            catch (System.Runtime.InteropServices.ExternalException)

            }
        }
    }
