ASP.NET中ListBox多選模式時擷取其選中項

 

ListBox多選模式(SelectionMode=Multiple)的使用--星燭網

把ListBox的屬性設為:SelectionMode=Multiple
可以實現ListBox的多選功能.

要擷取這些選中的ListItem,在WinForm下輕而易舉!

this.lst_AXzhz.SelectedItems;

但在ASP.NET下卻要麻煩一些!(也可通過指令碼實現.麻煩,只用在不進行PostBack的情況下,就不說了.)

            ListItemCollection items = new ListItemCollection();
            foreach (ListItem item in this.lst_AXzhz.Items)
{
function onclick()
{
function onclick()
{
this.style.display='none'; Codehighlighter1_137_259_Open_Text.style.display='none'; Codehighlighter1_137_259_Closed_Image.style.display='inline'; Codehighlighter1_137_259_Closed_Text.style.display='inline';
}
