How to remove one item from string in a textbox

I have a gridview with 2 columns.

First field contains checkbox named chkSelect and second column is a label which is binded with EmailId.

<asp:GridView ID="gvwNewsLetter" runat="server" AutoGenerateColumns="false" DataKeyNames="UserID">
<Columns>

<asp:TemplateField HeaderText="Select">
    <ItemTemplate>
    <asp:CheckBox ID="chkSelectMail" runat="server" />
    </ItemTemplate>
</asp:TemplateField>

<asp:TemplateField HeaderText="EmailID">        
    <ItemTemplate>
    <asp:Label ID="lblEmail" runat="server" Text='<%#Eval("EmailID")%>' ></asp:Label>
    </ItemTemplate> 
</asp:TemplateField>

</columns>
</asp:GridView>

When I check each checkbox I have to display mailid in corresponding row in a textarea which is outside gridview like" [email protected],[email protected]". If I uncheck inbetween I have to remove that particular id from textbox. Can anybody help give the code to remove mailid on unchecking the checkbox.

Can you not just rebuild the entire string each time a checkbox is checked/unchecked? Might be faster than trying to parse through and modify the existing string each time.
