ListView 排序问题
在
DataGrid
中有自带的排序，但是在
ListeView
中却没有这一项，下面就给出我平时用的
ListView
的排序使用方法，给志同道合的朋友们参考参考：
在
ColumnClick
事件下添加：
其中要注意：
int sortColumn=-1;
其中
sortColumn
用来记录上次排序的列的索引
private
void listView1_ColumnClick(object sender, System.Windows.Forms.ColumnClickEventArgs e)
{
if(this.listView1.SelectedItems.Count!=0)
this.listView1.SelectedItems.Clear();
if (e.Column != sortColumn) //first use
{
// Set the sort column to the new column.
sortColumn = e.Column;
// Set the sort order to ascending by default.
listView1.Sorting = SortOrder.Ascending;
}
else //second or more use
{
// Determine what the last sort order was and change it.
if (listView1.Sorting == SortOrder.Ascending)
listView1.Sorting = SortOrder.Descending;
else
listView1.Sorting = SortOrder.Ascending;
}
// Call the sort method to manually sort.
listView1.Sort();
// Set the ListViewItemSorter property to a new ListViewItemComparer
// object.
this.listView1.ListViewItemSorter = new ListViewItemComparer(e.Column,
listView1.Sorting);// ListViewItemCompare
r
要用到下面的类
}
一个新的类
class
ListViewItemComparer : IComparer
{
private int col;
private SortOrder order;
public ListViewItemComparer()
{
col=0;
order = SortOrder.Ascending;
}
public ListViewItemComparer(int column, SortOrder order)
{
col=column;
this.order = order;
}
public int Compare(object x, object y)
{
int returnVal= -1;
returnVal = String.Compare(((ListViewItem)x).SubItems[col].Text,
((ListViewItem)y).SubItems[col].Text);
// Determine whether the sort order is descending.
if(order == SortOrder.Descending)
// Invert the value returned by String.Compare.
returnVal *= -1 ;
return returnVal;
}
}
