Are you creating the select element form the code-behind or in the markup? You can't do it both ways.

If you are adding the control via code-behind then it is already a server control. If you are creating it in the markup then you must specify the runat=server attribute.

If you are creating the select via code-behind why are you not using an ASP.NET Dropdownlist control?

It isn't difficult to solve at all when you know and understand what you are doing.

Poor planning on your part is no excuse for rudeness. If you had properly planned this project you would not be rushing to implement something the day you are to deliver. That is inexcusable.

Declare your tag like this:

HTML

<select id="mySelElement" runat="server">
.......
.......
.......
</select>

Then you should be able to access your html element from your code behind like this:

string selectedValue = mySelElement.Value;

Did you get any compile error? If not, you can ignore the red line. And you have not specified an id attribute to the select tag. Without an id attribute, you cannot access it from code-behind.

WebMethod called from Javascript mis-behaving

Hey guys,

Hoping someone might be able to shed some light on a problem I am currently having.

I have a WebMethod being called by some javascript code, everything is working as it should, the WebMethod is a static string.

I am writing the output (which contains a small amount of html) to a hyperlink on my page (I'm adding a product to a basket and updating the link to the basket with item total etc.).

On my local dev machine, and on a staging version of the website (a copy of live) this all works nicely, the hyperlink shows what it is supposed to. But when put live, the WebMethod is called fine, and the output comes out in JSON format. This in itself I didn't think was a problem as I can just use jquery to parse the JSON, but it fails in firefox as being invalid JSON.

What's even weirder is that when I created a 2nd test version of the page (a carbon copy, just with the name changed), that behaves perfectly on live, without the need for JSON parrsing.

This isn't a problem in all browsers, IE, Chrome (release) and the latest Safari all pop the raw JSON in as the hyperlink text, Firefox (4) seems to parse it and shows the correct HTML.

Can anyone think why it would behave differently between 2 identical pages, where only the name is slightly different, and what the best way to parse the JSON is when it is returned from the WebMethod. Does it have to come back as JSON, I know xml is an option but really I could do with just a string..

I tried clearing all of my temporary files, so I know it's not a caching issue.

Live server (and the staging one too):
Win Server 2003
IIS6

The website is .Net 3.5, C#

Thanks in advance!

If the Pictures folder is under the root folder of your web application than this exception will be thrown. The ../ is attempting to go above the root folder, which is not allowed.

You have to use the tilde character "~" to specify a path who start from the root of your web app.

the code will be :

fupPicSummary.PostedFile.SaveAs(Server.MapPath(@"~/Pictures/summary_" + campaign.ID + ".jpg"));

To do that you would need to create a create another page that does not use the master page or use CSS to remove the master page elements when it is displayed. Then have the user save that page. This is what most "printer friendly" pages do.

You can't create another page dynamically, which appears to be what your are thinking. You must create the page before hand, just like any other asp.net page in your application. Or you use CSS to remove the masterpage elements. This method is used extensively in SharePoint 2010.
