动态生成控制丢失选择状态 [英] Dynamic generate control loss state of selection

问题描述

我动态生成复选框控件。

在进程控制功能中，我的复选框始终为false（chk.Checked）。

为什么我的Checkbox检查状态丢失。 />
请给我正确的解决方案。

I Dynamic generate checkbox control.
In Process control function my checkbox is always false (chk.Checked).
Why my Checkbox check state is loss.
Please give me proper solution of this.

protected void Page_Load(object sender, EventArgs e)
    {
        PopulateLeftSearchPane();

}

PopulateLeftSearchPane()
{
    UpdatePanel myupdpnl = new UpdatePanel();
               myupdpnl.ID = "upnl" + cn.AspectID + "_" + cn.TraitID;

                CheckBox chk = new CheckBox();
                chk.ID = "chktrait" + cn.AspectID + "_" + cn.TraitID;
                //string uniqueID = System.Guid.NewGuid().ToString().Substring(0, 5);
                //chk.ID = "chktrait";
                //chk.ID = "chktrait" + cn.AspectID + "_" + cn.TraitID + uniqueID;
                chk.Text = cn.ValueName;
                chk.Attributes.Add("AspectID", cn.AspectID.ToString());
                chk.Attributes.Add("TraitID", cn.TraitID.ToString());

                chk.AutoPostBack = false;
                //CheckBox chk = (CheckBox)ctrl;
                //  chk.CheckedChanged += new EventHandler(CheckBox_CheckChanged);
                // chk.CheckedChanged += new EventHandler(this.CheckBox_Click);
                chk.Attributes.Add("onchange", "Javascript:return CallSearchResults('" + chk.ID + "','" + cn.AspectID + "','" + cn.TraitID + "','" + cn.ValueName + "'" + ");");
                myupdpnl.ContentTemplateContainer.Controls.Add(chk);
              
                //myupdpnl.ContentTemplateContainer.Controls.Add(chk);

                divaccordioninner.Controls.Add(myupdpnl);
