i have devexpress ASPxMenu control on my form and also other controls like textbox,button etc.
If the user changes the text in the textbox and clicks the menu control i would like to prompt
the user through javascript or server side coding that he has not saved his changes and moving on
to other form.
I tried with ajax update panel but that update panel use to get postback on textchanged event of textbox .So if I change textbox contents and press save button then it use to postback the form without
the code for click of button getting executed.

Can this be done through javascripting?

Yes. You need to keep a flag which sets when value changes in the text box. Hook a JS function on the OnUnload event and check this flag's status. If it is set, display the prompt.

The answer, as you've been told, is yes. It's really easy. Perhaps you should buy a javascript book and read it ? There's an event that fires if your textbox text changes, when that fires, you set your flag and you check it in the event, as you were told.

i am using asp.net + C#
in my page i use label for "Bio post" ,to display.If the user enter datas like "aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa"etc. with out enter any space. the alignment problem will occur .i want to display all the details like
"aaaaaaaaaaaaaaa"
"aaaaaaaaaaaaaaa"
"aaaaaaaaa"
.Is it possible.I dont need scroll bar in that. if the text not fix in specified width of that label it will come next line.
for eg:in gmail if we type subect only letters like "11111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111 " but when we open it the subject display properly like
"111111111111111111111111111111111111111111111"
"111111111111111111111111111111111111111111111"
"111111111111111111111111111111111"
is any way to solve like this .and this fix in page width.
I use text box to display data .but i dont need that scroll bar when we set wrap="true".i need to display all the details with out scroll bar.

You mean textbox will automatically adjust its height on user entry ??

I think you need to use Javascript to do this. Smile | :)

<html>
<head>
<script>
function adjustSize()
{
var tbData = document.getElementById('tb').value;
document.getElementById('tb').style.width = 10 + tbData.length * 4 +'px';
}
</script>
<body>
<input type='text' id='tb' onkeydown='adjustSize()' style='width:10px' />
</body>
</html>

Something like this.. But you need to adjust the code according to your need. Big Grin | :-D

Re: Flash Object With Master Page

you can't do that with a traditional master page. You need to use frames to create an area where a flash runs and is not refreshed. www.diawebster.com [^] has an example ( it's my website )

Accessing custom control using javascript on the client page.

I have been tasked with replacing some DOM and javascript with an ASP custom control.

The aspx page is using master pages.

What I need to do is access the custom control with javascript in the aspx page. The control and its C# code behind are working, but I need to access a listbox contained within the control. I seem to be unable to access the control at all.

For example, in the aspx page I have the custom control like this:

<uc1:_Locations ID="_Locations1" runat="server" />;

In another page using an AJAX slider control, I have been able to access it like this:

var sliderUpdater = $find("SliderBehavior");

... then I am able to get and set properties for the slider.

However, trying similar approaches with our custom control all results in returning null from the $find. Note: our control does not currently have any extenders or BehaviorID.

I will post more code details if necessary.

Any ideas, help, or links would be appreciated.

Thank you.

What ID are you using in the find? Don't forget about the name mangling that ASP.NET applies to IDs

Yes I am aware of the name mangling, and have tried all my usual solutions. I will post more details and examples later.

When I try this:

var foo = $find<"%=_Locations1.ClientID%>");

The dynamic page during debug shows:

var foo = $find"ctl00_ctl00_ContentPlaceHolder1_ContentPlaceHolderMain__Locations1");

and foo is null after stepping through it.

IsDBNull is not evaluating correctly

Everytime I try to load a datagrid I get that a dbnull can't be convert to a string. I have included the following on the field that I am trying to convert to a link (with document location and name included).

<%#iif (IsDBNull(Container.DataItem("LinkName"))= True, "", ViewDocument(Container.DataItem("LinkName")))%>

It always goes to my sub routine ViewDoment() even when the Link Name is null. This works well on a field I'm making visible depending on if this same field is null or not but it won't work for the sub routine. Can anyone explain to me why or tell me what is wrong with the code?

Thanks,
Carolyn

This would work if you used a decent language....

iif evaluates both sides of the equation if I remember correctly. You should write a method that is passed the data item, and inside that, work out if it's DBNull using an if statement, not iif

Anybody who uses iif, even if they know that both results can be evaluated is asking for trouble, IMHO. I never used it in classic VB because it was a library function that always produced a function call instead of inline code. I guess its still available for compatibility, but it leads people to think that they can write the kind of code in the OP. Dead | X|

Hi,

I am using asp.net built in membership mechanism for registration and login in.

I recently transferred a website to a different hosting including the sql server database. After transferring the website all the previous user who registered now can't login with their user name and password. Password recovery says that the user name doesn't exist.

However, new account registration works and there is no problem logging in with the new account.

Does anyone know what the problem is?

Thank you for the time.

Sounds obvious. Your SQL migration did not work, the data for old users was lost.

The username is in the database. That's the thing. I checked it.
When I try to register same user it throws a duplicate record error for the username. That's a confirmation that it's in the db.
