如何获得选定的项目计数在asp:checkboxlist中 [英] how to get selected items count in asp:checkboxlist

问题描述

我有一个复选框列表控件

i have a checkboxlist control

<asp:CheckBoxList ID="chkselectedItems" Font-Size="12px" runat="server"> 
 </asp:CheckBoxList>

并且我在其上动态创建了listitems.如果我从复选框列表中检查了多个项目，那么我如何使用asp.net获取所选项目的计数

and i created listitems on it dynamically.If i checked more than one item from the checkbox list, How i get the selected item count using asp.net

谢谢

推荐答案

编辑

int numSelected = 0;
foreach (ListItem li in chkselectedItems.Items)
{
if (li.Selected)
{
numSelected = numSelected + 1;
}
}
Response.Write("Total Number Of CheckBoxes Selected:");
Response.Write(numSelected);

上

public string[] CheckboxListSelections(System.Web.UI.WebControls.CheckBoxList list)
{
 ArrayList values = new ArrayList();
 for(int counter = 0; counter < list.Items.Count; counter++)
 {
  if(list.Items[counter].Selected)
  {
   values.Add(list.Items[counter].Value);
  }    
 }
 return (String[]) values.ToArray( typeof( string ) );
}
