i think you can use html control and fill the drop down when page loads.
this will load the datas when page loads and minimize loading time.

main diff..
Interface-all the methods should be a abstract...
abstractclass-it have normal method and or abstract method......

If I'm not mistaken then Eval can only be used within GridView, Repeater, DataGrid, ... and not in a Hyperlink.
1) try to simply remove the Eval, if this doesn't work ...
2) Call a method on your code behind code that will return the string you need:
'<%# "FrmTempEmployeeEdit.aspx?Code=" + MyMethod("ddlcontractor.selecteditem.value") %>'
in code behind
protected string MyMethod(string s)
{
return Server.UrlEncode(s);
}

Don't do something like that, it is very ugly, not maintainable, not extensible, error prone, ...

Good Morning,
Friends, This is first time that I haven't got any reply of my post even after 26 hours nomally I get within one hour. My question could be tricky but not lengthy (I think) so here I am repeating my question again. I hope I will get answer this time. Please. It is urgent.
I am calling a .Net webservice in javascript by using "webservice.htc". It is working perfectly in IE 6 and 7 but unfortunately not in Firefox. I need to fix this problem in firefox. Please tell me solution how can I call a webservice using javascript in Mozilla Firefox browser? Please.
Kind Regards,
Abubakar

Hi Abubakar,
The question comes up again and again, but nowhere in the web seems to be the correct answer (although I describe it in my German JavaScript book since quite some time). The topic is using JavaScript to call Web Services from within Mozilla type browsers. Whereas this is quite well-documented and works more or less seamlessly with PHP Web Services, .NET Web Services are problematic. Calling the Web Service works, as does parsing the return data. However, on the server end, only empty parameters arrive.
The trick is to manually set the type for the parameters you are sending to the server. So after creating a parameter:
var p = new SOAPParameter(value, name);
Then, you load the correct type; in this case, I am using string, but you could use other schema types like integer, as well:
var enc = new SOAPEncoding();
enc = senc.getAssociatedEncoding(
"http://schemas.xmlsoap.org/soap/encoding/",
false);
var coll = enc.schemaCollection;
var type = coll.getType(
"string",
"http://www.microsoft.com");
Finally, you link the type to the parameter:
p.schemaType = type;
And that's it! The rest is business as usual: Instantiate the SOAPCall class, set the required properties, call encode(), call asyncInvoke(), implement a callback function, and you are done.
By the way: When using the Atlas framework, you do not need this browser-specific code any more; calling .NET Web Services works in a browser-agnostic fashion here.
SSK.

HI,
Thanks for this article, I have already seen this article and tried as well. It gives me error on very first line.
var p = new SOAPParameter(value, name);
I think browser doesn't recognise this. I neither understand this line, It will be really nice if you explain this little bit more or give a short example;
"The rest is business as usual: Instantiate the SOAPCall class, set the required properties, call encode(), call asyncInvoke(), implement a callback function, and you are done."
Regards,
Abubakar

As I told you, *.htc doesnt work on non-IE browsers.
Abubakarsb wrote: lease tell me solution how can I call a webservice using javascript in Mozilla Firefox browser?
Okay. you can call a webservice by using XMLHttpRequest Object..
Example ~
var req;<br />
var isIE;<br />
<br />
function initRequest(url) {<br />
if (window.XMLHttpRequest) {<br />
req = new XMLHttpRequest();<br />
} else if (window.ActiveXObject) {<br />
isIE = true;<br />
req = new ActiveXObject("Microsoft.XMLHTTP");<br />
}<br />
}<br />
<br />
<br />
function CallWebService(url) {<br />
<br />
initRequest(url);<br />
<br />
req.onreadystatechange = processRequest;<br />
req.open("POST", url, true); <br />
req.setRequestHeader("Content-Type", "text/xml");<br />
req.send(null);<br />
}<br />
<br />
function processRequest() {<br />
if (req.readyState == 4) {<br />
if (req.status == 200) { <br />
var message = req.responseXML;
}<br />
}<br />
}<br />
<br />
Note:
#1. The parameter called "url" of "CallWebService" method is the URL of Web Service.
#2. You should use "POST" if you wanna invoke the .NET Web Service. AFAIK, the .NET Web service used "HTTP POST" by default. If you wanna use "HTTP GET", you have to change the setting in Web.Config.

Thanks a lot for brief reply Michael, I checked it, this is so far so good. There is no javascript error which is great. Now I want to call a "WebMethod" named "testWebService" from my webservice and want to pass and get some values from "testWebService". How is it possible? Plz.

Note: Even though I'm sure that it can be done with pure Javascript, it is toooo much work to do if your project is big. So, I would like to suggest you to try some Ajax frameworks (ASP.NET Ajax)or Javascrpt framework (Prototype javascript library)....

Hi Friend,
I just checked one thing, In following code I am getting status value 500 but not 200 which is require. so what could be wrong?
function processRequest()
{
if (req.readyState == 4)
{
alert(req.status);
}
}
|
|
|
|
|
You can use "statusText" to know what problem is.
eg:
alert("Problem: " + req.statusText);
Internal Error 500
The server encountered an unexpected condition which prevented it from fulfilling the request.
I would like to suggest you one thing. It is better if you try this in new project.
#1. Create Web Project (C#)
#2. Add Web Service item to your web project.
#3. Paste Web Service Code that I gave you.
#4. Rebuild the application and test whether your web service is working fine or not.. (If you don't know know how to test the web service, I will tell you one simple way. Click "Add Web Reference" and find the web service. If you found the correct web service, click to this link. it will show two functions (testwebservice1 and testwebservice2). then, click on this link and type some data and click "Invoke" button. )
#5. If those steps above are working fine, paste the javascript code to your aspx page. and paste the HTML code.
#6. Check the url whether it is correct or not. (the url from sample might not be matched with the actual URL of your project)
#7. then, try to invoke the function which has no parameter first.... if it is working fine, try another function with argument...
if you are still getting the error, let me know which step you got error... The code that I gave you has been tested with Visual Studio 2005 on Windows XP. It is working fine. Please try first with my code without modifying anything... if it works then you can carry on with your code....

I tried same way as u said even with your code and I created a new project as well. It is really strange. I am using following statement. It works perfectly in IE6 and IE7 as well but unfortunately not in Firefox which I really need. Also tell me how can I get value from that specific xml tag but this is next step.
function processRequest()
{
if (req.readyState == 4)
{
if (req.status == 200)
{
var message = req.responseXML; //Result in XML.
alert(message.xml);
}
}
}
