Problem accessing hidden form field on postback

[xtremeLogic]

Hi,

I have a hidden form field that I use to keep track of some client side changes in my aspx page:

<input type="hidden" id="hdDeliveryMethod" value="delivery">

However, when I try to read the value of the control on postback, I get a null reference:

Dim strDeliveryMethod As String = Request.Params("hdDeliveryMethod")

When I run a debug on this line, I get strDeliveryMethod = Nothing. I have also done some Watches to check Request.Params and Request.Form but I can't seem to find my hidden control in the list.

I would really appreciate it if someone could tell me how to get the value of a hidden form field on postback.

Thanks,

Add the name attribute

<input type="hidden" id="hdDeliveryMethod" name="hdDeliveryMethod" value="delivery">

This should get you what you want
Request.Form("hdDeliveryMethod")

fyi, i figured out how to access the hidden field using:

Request.Form.Get("hdDeliveryMethod")

You might also prefer to add a runat=server attribute to the control and instantiate it in the code-behind, or, easier yet, a drag a hidden control from the HTML tab in the toolbox, right-click it and select "run as server control".
