C#对datagridview数据排序

Question

举个例子有1个对姓名进行排序的button，点击之后对datagridview里面的数据进行排序

Answer 1

排序原理一般是因为DataView有排序功能.下面方法对DataGrid和GridView都适用,操作步骤如下:

1.在需要排序的字段里加:SortExpression,如:
<asp:BoundColumn DataField="D_DATE" HeaderText="申报日期" SortExpression="D_DATE">
</asp:BoundColumn>
----------------
2.在PageLoad()里:(即开始Load页面时以什么方式排序)
ViewState["SortOrder"] = "D_DATE";
ViewState["OrderDire"] = "ASC";
----------------
3.在绑定Grid时:
假设数据源为DataView,ID为objDV.
string sort = (string)ViewState["SortOrder"] + " " + (string)ViewState["OrderDire"];
objDV.Sort = sort;
this.GridView1.DataSource = objDV;
this.GridView1.DataBind();
----------------
4.在GridView的Sorting事件中:
protected void GridView1_Sorting(object sender, GridViewSortEventArgs e)
{
string sPage = e.SortExpression;
if (ViewState["SortOrder"].ToString() == sPage)
{
if (ViewState["OrderDire"].ToString() == "Desc")
ViewState["OrderDire"] = "ASC";
else
ViewState["OrderDire"] = "Desc";
}
else
{
ViewState["SortOrder"] = e.SortExpression;
}
Bind();//绑定Grid方法
}
(如果是DataGrid,则为SortCommand事件)

参考资料：此方法借鉴了清清月儿的博客,在此感谢

Answer 2

this.dataGridView1.Columns["列名"].SortMode =
DataGridViewColumnSortMode.Automatic;
如果列名不确定的话就用下标
this.dataGridView1.Columns[0].SortMode =
DataGridViewColumnSortMode.Automatic;
