如何在asp.net一个复选框列表获取所选的索引。我应该通过循环来查找列表框中是否选择我可以知道没有这样做。我想这样做。
如果(的CheckBoxList选择)
{做这个}
其他
{做到这一点}
如何如果选中该复选框列表或找到不asp.net
INT roleselected = ckl_EditRole.Items.SelectedIndex;
有关的CheckBoxList,的SelectedIndex
会给你刚才在的CheckBoxList的一个选择的索引。如果它不是-1,被选中然后什么。这可能是足以让你在找什么。

How to get selected index in a check box list in asp.net. Should I loop through to find whether the list box is selected or can i get to know without doing that. I want to do this
if(Checkboxlist selected) {do this} else {do this}
how to find if the check box list is selected or not in asp.net
int roleselected = ckl_EditRole.Items.SelectedIndex;
For CheckBoxList, SelectedIndex
will give you just the first selected index in the CheckBoxList. If it's not -1, then something was selected. This may be enough for what you're looking for.
if( ckl_EditRole.SelectedIndex != -1 )
{
// Do Something
}
But, since the CheckBoxList can have multiple selections, you probably want to loop through the Items and look for the selected ones.
foreach( ListItem li in ckl_EditRole.Items )
{
if( li.Selected )
{
// Do Something
}
}
