不要意思,发错了,应该是这个:
/// 获得CheckBoxLis,RadioButtonList,ListBox控件所有选中值并以逗号格开,形式："2,3,4"
/// </summary>
/// <param name="listctrl">CheckBoxLis,RadioButtonList,ListBox控件</param>
/// <param name="type">类型，是想获得Value还是Text值</param>
/// <returns></returns>
public virtual string GetCtrlSelValue(Control listctrl,string type)
{
string str_Value="";
switch (type)
{
//＝＝＝要选择的是value＝＝＝
case "value":
{
//＝＝＝CheckBoxList＝＝＝
if (listctrl is CheckBoxList)
{
for (int i=0;i<((CheckBoxList)listctrl).Items.Count;i++)
{
if (((CheckBoxList)listctrl).Items[i].Selected==true)
{
str_Value=str_Value+((CheckBoxList)listctrl).Items[i].Value+",";
}
}
if (str_Value!="")
{
str_Value=str_Value.Substring(0,str_Value.Length-1);
}
}
//＝＝＝RadioButtonList＝＝＝
if (listctrl is RadioButtonList)
{
for (int i=0;i<((RadioButtonList)listctrl).Items.Count;i++)
{
if (((RadioButtonList)listctrl).Items[i].Selected==true)
{
str_Value=((RadioButtonList)listctrl).Items[i].Value;
}
}

}
//＝＝＝ListBox＝＝＝
if (listctrl is ListBox)
{

for (int i=0;i<((ListBox)listctrl).Items.Count;i++)
{
if (((ListBox)listctrl).Items[i].Selected==true)
{
str_Value=str_Value+((ListBox)listctrl).Items[i].Value+",";
}
}
if (str_Value!="")
{
str_Value=str_Value.Substring(0,str_Value.Length-1);
}
}
break;
}
//＝＝＝要选择的是Text＝＝＝

用循环

[gd4134]

//循环取出控件
for (int i = 0; i < CheckUserAll.Items.Count; i++)
{
if (CheckUserAll.Items[i].Selected == true)
{
//选中的。。
}

}

[blueskygenius]

foreach(ListItem li in this.CBL1.Items)
{
if (li.Selected)
{
PeopleHobby = PeopleHobby + li.Value + ",";
}
}
if (PeopleHobby.Length != 0)
{
PeopleHobby = PeopleHobby.Substring(0, PeopleHobby.Length-1);
}

简单点的:
protected void myCheckBox_CheckedChanged(object sender, EventArgs e)
{
Response.Write(myCheckBox.Checked ? "选择了" : "未选择");
}

[xuan505]

for (int i = 0; i < CheckUserAll.Items.Count; i++)
{
if (CheckUserAll.Items[i].Selected == true)
{





}
