JQuery Ajax xml request "parsererror"

2009-11-25T15:32:00.000-08:00

I was trying to use JQuery Ajax Request but I faced a error when Ajax Object starts processing the ResponseXml it always show error "parsererror".
this is my JQuery code.

var code = '123';
$.ajax({
                type: 'GET',
                url: 'ajxserv/?code=' + code,
                dataType: 'xml',
                success: function(xml) {
                    alert(xml);
                    alert($(xml).find("Table").text());
                    $(xml).find("Table").each(function() {
                        alert($(this).find("Title").text());
                    });
                },
                error: function(XMLHttpRequest, textStatus, errorThrown) {

                    alert(textStatus);

                }
            });

I tried to change the url of the request to a local Xml File "test.xml" it work OK but when I change the extension it was not working and shows the "parsererror" exception. after hours of Googling to find a solution I found it on StackOverflow.com.
simply the solution is that you have change the Response MIME type from "text/html" to "text/xml". To do that only you have to add:

Response.ContentType = "text/xml";

before your Response.Write("xml data");

2 tips on fly about Google Chrome

2009-06-19T09:36:00.000-07:00

Tip #1: using incognito mode to login to web application with two users in the same time.

you can login to the same web site (Forms Authentication) with more than one user by doing the following:

1- open chrome.

2- browse to the site.

3- login in normally with userA.

4- press ctrl+shift+N to open incognito mode.

5-browse to the site again.

6-login again with User B.

Tip #2: Reload Page Source (Simply press F5)

When you view the source of any page on Google Chrome you can hit F5 to reload the Page Source. its helpful for developers while tracing and debuging.

by the way you can browse to the page source direct by writing "View-Source:[URL]" in the address bar.

Report Viewer Control is not appearing when running the web form

2009-05-30T14:45:00.000-07:00

Issue:

One day I needed to use a Report Viewer to persent a SSRS (SQL Server Reporting Service) Report hosting at the SQL Server. I did every thing and when I ran the web from the whole report viewer was not appearing in the page?!

Solution:

in case you are trying to view a remote (stored in SQL Server) Report you have to change the value of report viewer "Processing Mode" property to "Remote".

and thats it..

Disabling Button On Click

2008-11-22T07:18:00.000-08:00

Sometimes you need to avoid multiple submission by clicking the a button multiple times to avoid that add the following javascript code to your page or script file:

function Button_Clicked(btn) {
   if (typeof(Page_ClientValidate) == 'function') {
       if (Page_ClientValidate() == false) { return false; }
       }
   btn.value = 'Please Waite...';
   btn.disabled = true;
   __doPostBack(btn.name, "");
   WebForm_DoPostBackWithOptions(new WebForm_PostBackOptions(btn.name, "", true, "", "", false, false))

}

Add the code function name to onclientclick property.

Right Click and uninstall the assembly from GAC and keep the bin assembly.

Error: "The type [Assembly] exists in both directories" & App_Code folder

2008-04-22T23:04:00.000-07:00

if you get some error like this:

Compilation Error Description: An error occurred during the compilation of a resource required to service this request. Please review the following specific error details and modify your source code appropriately. Compiler Error Message: CS0433: The type '[Assembly]' exists in both 'c:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\Temporary ASP.NET Files\sct_voting\008ce074\503ba4e5\assembly\dl3\b0922f94\4a4d3fb2_07a5c801\'[Assembly]' and 'c:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\Temporary ASP.NET Files\sct_voting\008ce074\503ba4e5\App_Code.o9o-qy-r.dll'

This error shows some times when you are using ASP.NET Web Project and you are placing you code files inside "App_Code" folder.

To solve this issue change the name of the "App_Code" folder to something else.

I think that it is a bug in ASP.NET Web Project building an assembly for the project and another assembly for the "App_Code" folder.

String.Trim() removes more than white spaces

2008-03-25T08:03:00.000-07:00

I faced a problem when reader from XML file. The problem was when getting the InnerText property it was including the new line \n, \t and so on becouse the innerText contains this values for example:


    
    1
    
    Test Category

When I was reading it I was using

string innerText = node.InnerText;

and it was giving me the newline character and other unwanted ccharacters.
Solution:
use Trim()

string innerText = node.InnerText.Trim();

Solution:"reset()" function is not working

2008-01-09T06:30:00.004-08:00

If you are trying to call a javascript function named "reset()" with a small "R" it will not work correctly because it "reset" function name is reserved. To solve this problem change the function name to any thing else or change it to "Reset()" with capital "R". Note that you should not start a function name with a small letter (Best Practices).
