问题描述
我正在使用DataGird显示详细信息.我的datagrid的数据源是一个列表.因此,我无法在网格中使用排序选项.我使用IComparable< item>在商务舱中并使用此方法.
I''m using DataGird to show details. My datagrid''s data source is a list. Therefore I can''t use the sorting option in the grid. I use IComparable<item> in business class and use this method.
public int CompareTo(Item item)
{
return ItemCode.CompareTo(item.ItemCode);
}
因此,我只能对ItemCode进行排序.我该如何改进它以便对给定的字段进行排序.
From this I can only sort to ItemCode. How can I improve this to sort for a given field.
推荐答案
public SortDirection GridViewSortDirection
{
get
{
if (ViewState["sortDirection"] == null)
{
ViewState["sortDirection"] = SortDirection.Ascending;
}
return (SortDirection)ViewState["sortDirection"];
}
set
{
ViewState["sortDirection"] = value;
}
}
protected void grd_InterviewCategoryList_Sorting(object sender, GridViewSortEventArgs e)
{
IntervewCategory ObjIC = new IntervewCategory();
DataTable dt = (DataTable)ObjIC.fn_getInterviewCategorylistDetails();
DataView dv = new DataView(dt);
if (GridViewSortDirection == SortDirection.Ascending)
{
GridViewSortDirection = SortDirection.Descending;
dv.Sort = e.SortExpression + " DESC";
}
else
{
GridViewSortDirection = SortDirection.Ascending;
dv.Sort = e.SortExpression + " ASC";
}
grd_InterviewCategoryList.DataSource = dv;
grd_InterviewCategoryList.DataBind();
}</pre>
