asp.net控件CheckBoxList使用详解_[Asp.Net教程]

asp.net控件CheckBoxList使用详解_[Asp.Net教程]
< asp:CheckBoxList ID = "cblJL" runat = "server" RepeatDirection="Horizontal" Width="100%">
< asp:ListItem>当前记录asp:ListItem>
< asp:ListItem>当前页asp:ListItem>
< asp:ListItem>全部记录asp:ListItem>
< /asp:CheckBoxList>

后台3种方式：
第一种：获得CheckBox的值
C#代码
string save_cblJL = "";

for (int i = 0; i < this.cblJL.Items.Count; i++)
{
if (this.cblJL.Items[i].Selected == true)
{
save_cblJL += this.cblJL.Items[i].Value + ",";
}
}
Response.Write(save_cblJL);
string save_cblJL = "";
for (int i = 0; i < this.cblJL.Items.Count; i++)
{
if (this.cblJL.Items[i].Selected == true)
{
save_cblJL += this.cblJL.Items[i].Value + ",";
}
}
Response.Write(save_cblJL);

第二种：获得CheckBox的值
C#代码
string str_Save_cblJL = "";
foreach (ListItem li in cblJL.Items)
{
if (li.Selected == true)
{
str_Save_cblJL += li.Value + ",";
}
}
Response.Write(str_Save_cblJL);
string str_Save_cblJL = "";
foreach (ListItem li in cblJL.Items)
{
if (li.Selected == true)
{
str_Save_cblJL += li.Value + ",";
}
}
Response.Write(str_Save_cblJL);
第三种：从后台给前台CheckBox赋值
C#代码
string strapp = "当前记录,当前页,全部记录,";
string[] strtemp = strapp.Split(’,’);
foreach (string str in strtemp)
{
for (int i = 0; i < cblJL.Items.Count; i++)
{
if (this.cblJL.Items[i].Value == str)
{
this.cblJL.Items[i].Selected = true;
}
}
}
