ValueCheckBox

有时候，我们不需要用CheckBoxList，这时就不能得到选中的值，其实，我们可以把值存在ViewState中，这样在服务器端可以取出来。

    public class ValueCheckBox : CheckBox
    {
        [Description("值"), DefaultValue(false),Bindable(true)]
        public string Value
        {
            get
            {
                return null == ViewState["Value"] ? string.Empty : (string)ViewState["Value"];
            }
            set { ViewState["Value"] = value; }
        }
    }

<%@ Control Inherits="Grain.Web.Manage.Facade.Controls.RoleOperatorControl" Language="C#" %>

<script runat="server">
    protected override void OnLoad(EventArgs e)
    {
        base.OnLoad(e);
        
        
    }

    protected void btnSave_Click(object sender, EventArgs e)
    {
        foreach (RepeaterItem riMenu in this.repMenu.Items)
        { 
            Repeater repOper = riMenu.FindControl("repOper") as Repeater;
            foreach (RepeaterItem ri in repOper.Items)
            {
                ValueCheckBox vcb = ri.FindControl("ckOper") as ValueCheckBox;
                if (vcb != null && vcb.Checked)
                {
                    Response.Write(vcb.Value + "<br/>");
                }
            }
        }
    }
</script>
