c# asp.net send table checkbox value array via HTTP Post
===

i basically have this table with which i create dynamic checkboxes (the number of records may/will vary) the idea is that i can select a checkbox on whatever table row and "Send" those records.

I basically want to send an array of ID's off to a different page for processing - but im very stuck!

here is my table/form code

    <form action="processingpage.aspx" method="post">
                <asp:Repeater ID="GroupList" runat="server">
                <HeaderTemplate>
                   <table id="grouptable" class="table"> 
    	            <thead>
                            <tr>
    		                <th>Broadcast</th>
    		                <th>ID</th>
    		                <th>Name</th>
    		                <th>Last Modified</th>
    		                <th>Actions</th>
    	                </tr>
                        </thead>
                        <tbody>
                </HeaderTemplate>
                <ItemTemplate>
                            <tr>
                            <td>
                            <input type="checkbox" name="BroadcastSelect[]" value="<%# Eval("Group_ID") %>"</input></td>
                            <td><%# Eval("Group_ID") %></td>
                            <td><%# Eval("DESC") %></td>
                            <td><label id="test">hello</label></td>
                            <td><a class="btn btn-info" href="<%# Eval("gURL") %>">Edit</a>/td>
                            </tr>
                </ItemTemplate>
                <FooterTemplate>
                            </tbody>
                    </table>
                </FooterTemplate>
                </asp:Repeater>
                <input class="btn primary" type="submit" value="Broadcast"/>
                
                    </form>

i think this is sending the array ok as i managed to see this via Requestb.in

`BroadcastSelect[]TESTGROUP`  (which is one of the items i sent)

but on my receiving page i'm getting nothing but blank text i've tried

    Label1.Text = Page.Request.Form["BroadcastSelect[0]"];

and

    Label1.Text = Page.Request.QueryString["BroadcastSelect[0]"];

but no values are printed. Can anyone point me in the right direction please :)
