HI. a blind programming student from Australia and use the jaws for windows screen reader from http://www.freedomscientific.com. my problem is, the project is a standard login form in visual web developer express 2005. and the user types in their name, e-mail, user name, password, then confirm password. if the 2 passwords match, then a label with a welcome message and the name of the user taken from the text box. if you do not have the passwords matching, you get an error message. now, for some stupid reason jaws is not reading me the welcome message and the user name. so wondering, what am i doing wrong? how to get this to read correctly. any access technology specialists or users, who are blind or vision impaired here on this forum. will paste the code for the project below. any ideas, suggestions or work arounds or fixes are welcome. cheers Marvin.

I'm guessing the HTML output is not accessibility compliant as his screen reading software doesn't read part of the the content on the web page.
Abhijit Jana wrote: How this question comes into ASP.NET Forums.
Because he is asking about what he did wrong in making the ASP.NET page accessibility compliant.
Abhijit Jana wrote: and post in proper forum
As far as I can see he is posting in the proper forum.

HI. well my problem is my screen reader is not reading me that welcome message and the name of the user, and it does relate to asp dot net, because that was one of the exercises in the web programming chapter of the vb programming book. now, wondering, if it being hidden by some type of thing, and wonder if i need to use a separate text box or status bar. cheers Marvin.

You need to check for a null value (or DBNull.Value) before casting it.

OK, so you expected to post this in the VB forum and get help ? Wow. Even now, I don't see how we can help you. What value are you passing ? How are you passing it ? Why are you editing the value in the new page ? What do you mean, it's retaining the old value ? You haven't given anything like an explanation that gives us info we need to try to understand and help you.

Buy a basic programming book and read it. Don't post so much code that no-one will bother reading it.
rosae619 wrote: :Index was out of range. Must be non-negative and less than the size of the collection.
It means what it says. Look at the code where the debugger breaks. Is index < 0, or greater than the collection ? Never access a collection without first making sure the index you're about to use is valid. Read error messages, and then think about what they say. They mean what they say.

this is my question i want to put the functionality of onblur method of textbox is not in javascript but in c# but i am unable to find any similar or working functionality.
-------------------xxx-----Have any ideas----------------xxxxxxxxxxx-------------------
thanks.

There's a reason for this. The reason is that it would be idiotic for this to exist. You need to understand how web applications work, and you plainly do not. A web page that reloaded itself every time a textbox lost focus, would really, really suck. You can use C# code by making an AJAX call, assuming you know anything about AJAX.

Put your textbox inside an updatepanel. Set AutoPostBack=true and hook the TextChanged event handler. You can see the event fires on blur.

See, I would have told him how to write actual code, instead of using a framework that he doesn't understand in any way. But, your reply probably helped him more, I would have just tried to force him to consider becoming a programmer.

Agree 100%. I would have done that. OP said, he already started AJAX framework and I thought obvious answer would be helping on that. I am not sure how much he would have followed if I answer him in a different way.

Onblur can only be generated if the page is posted back.
In client server architecture, when a response is sent to the client, there is no connection between the client and the server. Thus when the page is posted back, that means another request is been made to the server with some postback info.
You can create an HTTPHandler to generate server side event, but to post back your page automatically when onBlur event of a textbox occurs, you need to do it through javascript.
Just do a postback of the page to your handler.. ![Rose | [Rose]](https://codeproject.global.ssl.fastly.net/script/Forums/Images/rose.gif)
Hope you understand!!!!

imgObj.style.position="absolute";
var X=event.x;
if(X<=screen.width*41/100)
X=X+100;
else if(X>=screen.width*59/100)
X=X-200-350;

1 - See the event handlers are hooked correctly.
2 - Take the viewsource of that page and see how it is rendered.
3 - Make sure you have JS enabled browser.

No, the odds seem low of the browser being broken. Your code obviously is. So, do some basic error checking, and if you need to ask again, try giving us some detail of what is happening, and show us code. This post is utterly useless. You've said to us 'my code is broken'. Great. How can we help without seeing it, or without you doing some basic work to check what is and is not working as you'd expect ?

I want to resize gridview column width dynamically like component art grid.
|
|
|
|

I think you need good knowledge of JS to do this. Take a good book and learn. I am not sure, but look at the JQuery library which may have some techniques to do this.
