ASP.NET/HTML: Use ASP.NET's label text/value in HTML's input value

Question

I have the following html codes (to be used in POST method):

// from Default.aspx
<input type="hidden" name="lblName" value="John" />
<input type="hidden" name="price" value="100.00" />

Is it possible to change the 'value' part by using the value/text ASP.NET label given below:

//from Default.aspx.cs
<asp:Label ID="lblName" runat="server" Text="John" />
<asp:Label ID="lblPrice" runat="server" Text="100.00" />

I just want to find a way to retrieve 'value' data dynamically coming from the ASP.NET label. Any suggestions?

Why not using a server side hidden control whose values could be modified dynamically from the server side:

<asp:HiddenField ID="lblName" runat="server" Value="John" />

Another possibility is to perform this on the client side using javascript: labels are usually rendered as span tags, so you will need to obtain the proper span by id and then assign it's innerHTML value to the hidden element. Using a javascript framework like jQuery might render this task much easier and guaranteed to work cross browser.

does the ID lblName the same as html input name? I'm trying to pass these values to a payment gateway.

Yes it is the same but ASP.NET could mangle the names and IDs of server side controls.
