[英]How to disable certain checkbox items in checkboxlist2 if a specific list item from checkboxlist1 is checked?
[英]How to know the checkboxlist items (from dynamically) are checked or not?
我在asp.net C#中创建了2个chekboxlist,此chek box列表的列表项是从数据库(动态地)填充的,然后我想检查这些复选框是否被选中? 请帮我...
或者您可以使用此代码
IEnumerable<int> allChecked = (from item in chkBoxList.Items.Cast<ListItem>()
where item.Selected
select int.Parse(item.Value));
试试这个代码:
String values = "";
for (int i=0; i< cbl.Items.Count; i++)
{
if(cbl.Items[i].Selected)
{
values += cbl.Items[i].Value + ",";
}
}
values = values.TrimEnd(',');
或者您可以使用此代码(Linq)
IEnumerable<int> allChecked = (from item in chkBoxList.Items.Cast<ListItem>()
where item.Selected
select int.Parse(item.Value));
尝试这个
string ids=string.Empty;
foreach (ListItem item in checkboxlist1.Items)
{
if(item.Selected)
ids+=item.Value+",";
}
ids=ids.Trim(',');
您可以使用SelectedIndex
来检查清单是否被选中:
if( ckl.SelectedIndex != -1 )
{
// Do Something
}
