目前有一datagridview控件,里面有个货币类型的列;我要实现的功能是,在此datagridview的底部固定一行,用于对货币列进行统计,并且当滚动垂直滚动条时,该列也一直保持在datagridview底部显示。
麻烦各位帮忙想个办法实现这样的功能,谢谢
7 个解决方案
#1
加一个控件如何?
#2
可以通过重写DGV实现,具体代码在网上挺多的。
#3
通过数据源计算这两列的和就好。
然后在
DataRow DR = DataSet.Tables[0]NewRow();
DR[1] = "1000.01";
DataSet.Tables[0].Rows.Add(DR);
然后在
DataRow DR = DataSet.Tables[0]NewRow();
DR[1] = "1000.01";
DataSet.Tables[0].Rows.Add(DR);
#4
google baidu
DataRow dr = ds.Tables[0].NewRow();
dr[0] = "总价:";
dr[1] = "200"; //总价200元吧
ds.Tables[0].Rows.InsertAt(dr, ds.Tables[0].Rows.Count-1);
datagridview.DataSource=ds.Tables[0];
#5
挺麻烦的,因为你增加统计行以后,还要考虑到排序的问题。
如果你的datatable每一类是与类型的,还得考虑类型问题。
我当时做的是在底部加了panle,用lable显示,去重写太麻烦了
