Use the below code .. the array list will hold the Selected check box value from checkbox list control

C#
ArrayList arrList = new ArrayList();
   for(int i=0;i<=CheckBoxList1.Items.Count -1;i++)
    {
        if (CheckBoxList1.Items[i].Selected)
        {
            arrList.Add(CheckBoxList1.Items[i].Value);
        }


}
   
v2
check this
C#
protected void Button1_Click(object sender, EventArgs e)
   {
       for (int i = 0; i < CheckBoxList1.Items.Count; i++)
       {
           if (CheckBoxList1.Items[i].ToString() == DropDownList1.SelectedItem.Text)
           {
               CheckBoxList1.Items[i].Selected = true;
               break;
           }
       }
   }
