如何在ASP.NET Web应用程序中分配checkboxlist。 [英] How to assign checkboxlist in ASP.NET web application.

问题描述

Hii..i有CheckboxList，其中我有5个复选框 - 选择全部，空手道，跆拳道，功夫，瑜伽。我想当用户选中第一个选项全选，然后自动选择所有复选框并显示在标签消息15000.And如果用户逐个检查，即检查空手道，然后消息显示5000 ......等等。或者用户如果喜欢空手道和瑜伽信息显示，空手道的费用总额为5000，瑜伽费为3000，那么应该显示8000.

   {
       if (CheckBoxList1.SelectedItem.ToString() == "Select All")
       {
           Lblselected.Text = "15000";

       }
       else if (CheckBoxList1.SelectedItem.ToString() == "Karate")
       {
           Lblselected.Text = "4000";

       }
       else if (CheckBoxList1.SelectedItem.ToString() == "Kickboxing")
       {
           Lblselected.Text = "6000";

       }

       else if (CheckBoxList1.SelectedItem.ToString() == "Kung Fu")
       {
           Lblselected.Text = "3500";

       }
       else if (CheckBoxList1.SelectedItem.ToString() == "Yoga")
       {
           Lblselected.Text = "1500";

       }

       else
       {
           Lblselected.Text = "0";

       }
   }
