首先是实现ListView控件的自定义排序,订阅ListView控件的ColumnClick事件
private void listView1_ColumnClick(object sender, ColumnClickEventArgs e)
{
if (this.listView1.Columns[e.Column].Tag == null)
this.listView1.Columns[e.Column].Tag = true;
bool tabK = (bool)this.listView1.Columns[e.Column].Tag;
if (tabK)
this.listView1.Columns[e.Column].Tag = false;
else
this.listView1.Columns[e.Column].Tag = true;
this.listView1.ListViewItemSorter = new ListViewSort(e.Column, this.listView1.Columns[e.Column].Tag);
//指定排序器并传送列索引与升序降序关键字
this.listView1.Sort();//对列表进行自定义排序
}
排序类的定义:
///
///自定义ListView控件排序函数
///
class ListViewSort : IComparer
{
private int col;
private bool descK;
public ListViewSort()
{
col = 0;
}
public ListViewSort(int column, object Desc)
{
descK = (bool)Desc;
col = column; //当前列,0,1,2...,参数由ListView控件的ColumnClick事件传递
}
public int Compare(object x, object y)
{
int tempInt = String.Compare(((ListViewItem)x).SubItems[col].Text, ((ListViewItem)y).SubItems[col].Text);
if (descK) return -tempInt;
else return tempInt;
}
}
