So far I have found PayPal Sample[^], There's a lot of code written for each step. At last you will find a logic on redirecting back to your webpage after completing transaction. I think There's same idea as in page for all transactional websites.

DropDownList behavior

An observation and a bit of a question:

I've got a DropDownList on a web page (C#, but that doesn't matter)

It is set to AutoPostback & ViewState is turned on.

IF there are duplicate Values in the dropdown (not the Text, just the Values), it will NOT maintain its selected index, but rather return from the postback with the first of the duplicate Values selected.

Example: This is what it looks like after a postback from selecting "CHAPLAIN"

<option value="TBD">ACQUIS & MATERIEL MGMT</option>
<option value="xxxxxxHolliT">AMBULATORY CARE</option>
<option value="xxxxxxBrownJ">ANESTHESIOLOGY</option>
<option selected="selected" value="TBD">ASSOC DIR/NURSING SVC</option>
<option value="TBD">ASST DIR/OPERATIONS</option>
<option value="xxxxxxWackeR1">BLIND REHABILITATION SVC</option>
<option value="TBD">CHAPLAIN</option>
<option value="TBD">CHIEF OF STAFF</option>

See what I mean?

Is this a known behavior? Or a bug?

Not Active7-Dec-10 10:46

AFAIK its know behavior. Selected status is stored based on the value not the ordinal, hence the SelectedValue property. With duplicate values it just picks the first one as you can see. It just doesn't make sense to have the same values for multiple items.

Sure it does, in circumstances a DropDownList is apparently no good for. Laugh | :laugh:

For instance, a list of Names, with their gender in the Value.

It's the other way around that wouldn't make sense. A list of 47 Bobs...you wouldn't know which one to pick even if their Values were different.
But Bob Smith, Bob Dobbs, Bob1 and Bob2 could all be male in Value.

No matter. I found a diffent way of doing what I was doing.

It simply means you are using the value field for something that it isn't intended to be. The value field meant in theory to be used like the key in a hashlist or the primary key in a table. If you have another value that you'll need, you can always add a custom attribute to each ListItem, but at the end of the day a single-selectable item control should have unique ids for each item...

I wasn't, now I am, then I won't be anymore.

i want to submit form in asp.net

I think that form object can be stored in formS variable by using "var formS = document.getElementById("form2")"
but i don't know how can i submit.

/////////////////////////////////////////////////////

function show_win(userName) {
var formS = document.getElementById("form2");
formS.action(); //<-- Here is error.

}

<asp:textbox id="TextBox1" runat="server">
<asp:button id="Button1" runat="server" text="Button" onclientclick="show_win('admin')">

Hi,

I want to ask where is the best place to save the web application version? because i want to show the version on my default page but I thought if there is a specific place to save other than Global file?

Thanks

As Hiren suggested, you can save it in web.config. I have several projects (small as well big) saving it in config file.

Place it in web.config in app settings section. Then you will be able to read it easily in code like
