CheckBox Gridview Enable and Disable

I have a gridview where the checkboxes start off disabled. I want to enable them when I click the edit button that's also in the gridview. Here's the markup

<asp:GridView ID="grd_Bookcode" runat="server" DataSourceID="sqldatasource1" 
autogeneratecolumns="False" onrowcommand="grd_Bookcode_RowCommand1" 
onrowdatabound="grd_Bookcode_RowDataBound">
<Columns>
    <asp:BoundField DataField="BookCode" HeaderText="Book Code"/>
    <asp:BoundField DataField="mag_name" HeaderText="Name"/>
    <asp:BoundField DataField="display_date" HeaderText="Display Date"/>
   <asp:TemplateField HeaderText = "PC">
        <ItemTemplate>
            <asp:CheckBox ID="CheckBox1" runat="server" Checked='<%# Eval("82_PC").ToString() == "1" ? true:false %>' Enabled="false" />
        </ItemTemplate>
     </asp:TemplateField>
     <asp:TemplateField HeaderText="eReader">
        <ItemTemplate>
            <asp:CheckBox ID="CheckBox2" runat="server" Checked='<%# Eval("83_eReader").ToString() == "1" ? true:false %>' Enabled="false" />
        </ItemTemplate>
    </asp:TemplateField>
     <asp:TemplateField HeaderText="Tablet">
        <ItemTemplate>
            <asp:CheckBox ID="CheckBox3" runat="server" Checked='<%# Eval("84_Tablet").ToString() == "1" ? true:false %>' Enabled="false"/>
        </ItemTemplate>
    </asp:TemplateField>
     <asp:TemplateField HeaderText="Mobile">
        <ItemTemplate>
            <asp:CheckBox ID="CheckBox4" runat="server" Checked='<%# Eval("85_Mobile").ToString() == "1" ? true:false %>' Enabled="false" />
        </ItemTemplate>
    </asp:TemplateField>
     <asp:TemplateField HeaderText="None">
        <ItemTemplate>
            <asp:CheckBox ID="CheckBox5" runat="server" Checked='<%# Eval("86_None").ToString() == "1" ? true:false %>' Enabled="false" />
        </ItemTemplate>
   </asp:TemplateField>
    <asp:CommandField ShowEditButton="True" />
</Columns>

And then here's the code that I'm trying to use. Basically, when I hit the edit button, I want the checkboxes themselves to be enabled. For whatever reason, the checkbox isn't enabled at all when the page loads back up. I just started off trying to enable "Checkbox1" after the edit button is clicked but eventually want to enable all 5 checkboxes. 

 protected void grd_Bookcode_RowCommand1(object sender, GridViewCommandEventArgs e)
    {
        if (e.CommandName == "Edit")
        {
            int index = Convert.ToInt32(e.CommandArgument);

            GridViewRow row = grd_Bookcode.Rows[index];

            CheckBox chk = (CheckBox)row.FindControl("CheckBox1");
            chk.Enabled = true;


        }
    }

If you want the Edit control to be different than the standard control, you should use the "EditItemTemplate". This will allow the edit row to have different controls, values, etc... when the row's mode changes.

Example:

        <Columns>
            <asp:TemplateField HeaderText="PC">
                <ItemTemplate>
                    <asp:CheckBox ID="CheckBox1" runat="server" Checked='<%# Eval("82_PC").ToString() == "1" ? true:false %>' Enabled="false" />
                </ItemTemplate>
                <EditItemTemplate>
                    <asp:CheckBox ID="CheckBox1" runat="server" Checked="true" Enabled="false" />
                </EditItemTemplate>
            </asp:TemplateField>
        </Columns>

I guess you could loop through all the rows of the GridView and enable the checkboxes something like below:

    protected void grd_Bookcode_RowCommand(object sender, GridViewCommandEventArgs e)
    {
        if (e.CommandName == "Edit")
        {
            for (int index = 0; index < GridView1.Rows.Count; index++)
            {
                CheckBox chk = grd_Bookcode.Rows[index].FindControl("CheckBox" + index + 1) as CheckBox;
                chk.Enabled = true;
            }
        }
    }

Hope this helps!!
