i having checkboxes created dynamically in page_load event , put in panel.

foreach (datarow dr in column_ds.rows)         {             column_checkbox = new checkbox();             column_checkbox.text = (string)dr["column_name"];             columnpanel1.controls.add(column_checkbox);         }

now want checked check box values in btn_click event. ideas? tried,

columnpanel1.findcontrol("column_checkbox");

and

  checkbox cb=(checkbox)findcontrol("column_checkbox");         if (column_checkbox.checked) { }         {             string name = column_checkbox.text;         }

on click event of button, can implement below logic.

protected void btn_click(object sender, eventargs e) {    foreach(var row in columnpanel1.rows)    {        var tempchkbx= row.controls[0] checkbox;        if(tempchkbx.ischecked)        {          //write code        }    } }
