Thread: Get Form Data - ShoppingCart.aspx

I have added a drop down box which has auto-post back. The problem I have is I can not access that posted data.

When the drop down is changed the page refreshes. Looking at the information sent I can see that correct data is posted as form data.

DropDownCountry:86

Yet when I try and access this information for DropDownCountry I just can't get it.
I have tried using response, commonlogic (all different types) and I just can't get that int.

At the moment I have just tried
CommonLogic.FormCanBeDangerousContent("DropDownCou ntry");
yet nothing.

Can anyone help, I have no idea why I can't access this posted int.

Thanks in advance.

EDIT:
Just to note the code I have posted creates a 500 error if you just load the page as DropDownCountry does not exist. So I know it is correctly seeing the post data when I change the drop down. I just can't do anything with it for some reason.

Is there something I am missing? This should be an easy school boy task but I really can't get it to work, any ideas?

Shouldn't it be DropDownCountry.SelectedValue ?

Just tried it with no luck. Even printing what information is shown the value is always the default 80 regardless of the value of the selected item.

Is there any reason why the dropdown would always use the first value even if not selected.

Just a bit of code I tried

int CountryID = 86;
CountryID = int.Parse(DropDownCountry.SelectedValue);

The odd thing is the first country is GB which has a id of 80. Using this code also produces 80 no matter what the selected value is.

What about?

Code:

DropDownCountry.SelectedItem.Text

No luck, it still doesn't work.

It returns the first loaded item not the selected one... Very odd.

edit:
Just tried
DropDownCountry.SelectedValue.Length

and it returns 0.

I am really not sure what to do about this.

Something odd to note.
If I use this code after the drop down has been filled out.

C#/VB.NET Code:

int CountryID = 86;
CountryID = int.Parse(DropDownCountry.SelectedValue); 


I get a countryid of 80, which is the default selected value. However when I select another value and the page automatically refreshes it does not update and stays at 80 yet the drop down selected value is the option you selected.

Solved the problem by turning off auto post back.

For some reason it does not work with auto post back enabled.
