Unable to read a sumitted form..

[Dobly]

You may have seem my post a little earlier, where my form had no veiwstate and was not posting any data back. I seemed to have that working now, but now there is a new problem.

I cannot read the submitted values...

Just to summarise, my form is in a nested user control. One that is 'loaded' by another user control , that is in turn, loaded by a base class. Something like that anyway.


I have put the following code in the Page.Load function of the user control with the form.

if (Page.IsPostBack)
{
temp = Request.Form.ToString();
strAmount = Request.Form["txtAmount"].ToString();
etc etc...

When I use the degugger to see the value of 'temp', this is what I see.. (Only the first part is shown here as it is a quite a long form)


"__VIEWSTATE=dDwtMTI3OTMzNDM4NDs7PrggHXYdc%2bfYaBGqGEob%2fwbeSdup&_ctl5%3a_ctl0%3a_ctl0%3atxtAmount=234& etc etc...

See the bit there 'txtAmount=234'? Thats the value I want... But the line...

strAmount = Request.Form["txtAmount"].ToString();

.. returns this error.

System.NullReferenceException: Object reference not set to an instance of an object.

Please help. I am at my wits end with this.

If you're using ViewState, then try this line:

strAmount = CStr(ViewState("txtAmount&quot)

Thanks for that. But when i tried youe line of code,

strAmount = CStr(ViewState("txtAmount&quot);

I got this error on compile.

(65): 'System.Web.UI.Control.ViewState' denotes a 'property' where a 'method' was expected

It doesn't help that I gave you the VB syntax and not the C# code:

strAmount =(string)ViewState["txtAmount"];
