关于Gridview排序时加载图片(急求)

[liufeizhiminRoy]

Gridview sort ui desgin

点击Header时,排序,向上排序时显示向上箭头的图片, 反之;

请问下面的代码中如何得到grCompanyScale.SortExpression的值, 我已经选择了某一列,但是它的值还是空,请看代码:

GridView gridView = (GridView)sender;

if (e.Row.RowType == DataControlRowType.Header)
{
int cellIndex = -1;
foreach (DataControlField field in gridView .Columns)
{
e.Row.Cells[gridView.Columns.IndexOf(field)].CssClass = "headerstyle";

if (field.SortExpression == gridView .SortExpression)
{
cellIndex = gridView .Columns.IndexOf(field);
break;
}
}
if (cellIndex > -1)
{
// this is a header row,
// set the sort style
e.Row.Cells[cellIndex].CssClass =
gridView .SortDirection == SortDirection.Ascending
? "sortascheaderstyle" : "sortdescheaderstyle";
}
}

GridView gridView = (GridView)sender; 

        if (e.Row.RowType == DataControlRowType.Header) 
        { 
            int cellIndex = -1; 
            foreach (DataControlField field in gridView .Columns) 
            { 
                e.Row.Cells[gridView.Columns.IndexOf(field)].CssClass = "headerstyle"; 

                if (field.SortExpression == gridView .SortExpression) //GridView后面多了個空格
                { 
                    cellIndex = gridView .Columns.IndexOf(field); //GridView后面多了個空格

                    break; 
                } 
            } 
            if (cellIndex > -1) 
            { 
                //  this is a header row, 
                //  set the sort style 
                e.Row.Cells[cellIndex].CssClass = 
                    gridView .SortDirection == SortDirection.Ascending 
                    ? "sortascheaderstyle" : "sortdescheaderstyle"; //GridView后面多了個空格

            } 
        }

点击按扭后，在按扭的事件中改图片

例如你用的是 ImageButton 那就在事件中改 *.ImageUrl 的值
