DropDownList behavior

GenJerDan7-Dec-10 9:03

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?

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')">

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

ConfigurationManager.AppSettings["YourApplicationName:VersionInfo"]

Hi,
I am developing a simple online DBMS to browse my database online.... the main concern for me is to clear everything from the PC when the user disconnect so no body can go and click (Back) on the browser and see the pages if the user forgot to close it.. what I have done so far is :

Session.RemoveAll();
Response.Clear();
Response.Redirect("Default.aspx");

I am sure this is not enough.. am I right? so what else I should include there?

You should really abandon the session rather than just remove all of the contents. The response.clear and redirect don't do anything to get rid of the history. You need to be looking more at the cache.

If you do everything in update panels or with other ajax methods, then the back button won't do much.

hide ajax files

hi guys,
my site will be using ajax methods and i don't want clientside to view my ajax(js) code when they view
the source code of my site..
Does anyone know how i can hide my ajax files so that they are not viewable on clientside?
For instance you can import a css file using the @Import command..I tried something similar in javascript
with below code:

var script = document.createElement('script');
script.src = '../ajax/login/login.js';
script.type = 'text/javascript';
document.getElementsByTagName('head').item(0).appendChild(script);

with the above, none of my methods in the login.js file are loading...

Please help me.

By definition, a client side file (which your ajxx/javascript files are) are sent to the client. In plain text. So no matter what you do, you cannot stop a determined user from viewing them. You can minify and obfuscate them, but while that may deter an inexperienced user, it won't stop anyone that knows what they are doing.

But the question is: why do you want to? Never, ever, put sensitive data in a javascript file.

Try using some encryption or obfuscation method to secure your client side javascript.

In general, you can't hide something from the client if you need the client to use it. My suggestion would be to convert all your js files to aspx files and set the content type. Have them do a referer check and set the caching options to not cache. It won't be good for performance and it won't stop a seriously determined person, but it should be a pretty big speed bump to most people.

Hi ,
I am facing an error from a long time.
My web application some times gives error 'The handle is invalid. (Exception from HRESULT: 0x80070006 (E_HANDLE))' on server. I never comes on production server. Then I just upload the bin folder again on server and it starts running fine. I don't know what is the actual reason behind this.
Some experts suggested Min pool size =1, I applied that but no luck.

I have attached error image.

Please let me know if you have any clue

thanks
