dynamic check box in gridview

Question

I have Datagrid in asp.net page with the below mentioned data 

Device Name	Column 1	Column 2
iPad	Check Box	Check Box
iPhone	Check Box	Check Box
iStore	Check Box	Check Box

 

For Example: - Like this

Here Check box is – Check Box Control on each Cell

Here Device_Name,Column1 and Column2 are column names, under these columns we have check boxes on both the columns, Please can anybody help me how do I we get to know which all the check box's are TICKED.

Once it has been TICKED I want to assign checked value (just to identify which are been ticked) to array list from Grid view (for storing purpose, later I will pass this array list to next page). 

Could you please someone help me one this

Please Note that: - while creating Gridview initially Check box will not be having any Id's because those check boxes are dynamically generated.

This is my C# code for creating dynamic Check boxes in Gridview :-

  protected void GrdOSInfo_RowDataBound(object sender, GridViewRowEventArgs e)

        {

         if (e.Row.RowType == DataControlRowType.DataRow)

            {

                for (int i = 1; i < 3; i++)

                {

                    //foreach (GridView row in GridView1.Rows)

                    //{

                    CheckBox chk = new CheckBox();

                    chk.EnableViewState = true;

                    chk.Enabled = true;

                    chk.ID = "chkb"+i;

                   

                    e.Row.Cells[i].Controls.Add(chk);

                    //}

                }

            }

        }

 

This is my asp.net code

<asp:GridView ID="GrdOSInfo" runat="server" CssClass="grid_table"

                onrowdatabound="GrdOSInfo_RowDataBound" BackColor="White" Width="200px"

                BorderColor="#999999" BorderStyle="None" BorderWidth="1px" CellPadding="3" GridLines="Vertical"

              >

                <HeaderStyle  CssClass="grid_head_row" Font-Bold="true" ForeColor="White"
