I am wondering if anyone knows good code that implements the Windows Explorer selection mechanism (for a DataGrid or HTML table). I know the basics of assigning attributes to DataGrid rows (eg. objDataGrid.Rows(index).Attributes("onclick")) which applies to HTML tables. But wondering if there's a good technique to do, for example:
1. Left-click on file/row to select it.
2. Left-click on a different file/row to select it, reseting previous selections.
3. Hold down CTRL + left-click on different files/rows to multiple select, thus retaining all selections during CTRL key is down.
4. Hold down SHIFT + left-click on different file/row and all files/rows between first left-click and second left-click + SHIFT key are selected.
5. Right-click on one of the selected files/rows brings up a context menu.
6. Right-click on a non-selected file/row selects it, deselects all others, and brings up context menu.
I have googled around and there are many examples, especially using the IE's onContextMenu event. However I still haven't found any code/library which does all 6 of the above (all-in-one). I am looking for something which is cross-browser too.
Anyone seen such a code/library that does the above 6?

You're gonna hate me, but I've just implememnted that in a grid control that we use here - complete with declarative context menus and graphics etc....unfortunately, with source code being our crown jewels, all I can do is offer to point you in the right dir....feel free to email

declarative context menus?
I have managed to create a nice CTRL, SHIFT selection & context menu system with my DataView (table).
CTRL select works nicely. However the SHIFT selection always seems to create a drag-selection between the start and ending rows.
A little reminder. CTRL select is when one holds the CTRL key and mouse left-click on rows to select individual rows (eg. row 1, 3, 5). SHIFT select is when one holds the SHIFT key and left-click on row 1 and then row 10 to automatically select all rows between 1 and 10.
Does anyone know how to prevent IE & FF from selecting the text inbetween the SHIFT selection phase?
Currently I use td background-color for selection and knowing what to delete, etc. Is there a better way to do this?

When we click on the close button [X] in the title bar of browser a event is fired i.e onunload(). In this event we can call a function say xyz(). Now in the function I want to do something which will prevent the window to close.
How can i do this.

IMO, you can set a message in the returnValue property of the event object, but you should use the onbeforeunload[^] event instead as the onunload is too late.

The User if clicks the next button on the same page the same page appers with the different content but if he clicks on back button in IE he is navigated back to the page.

I think they use a web developer program(like marcomedia dreamweaver or microsoft frontpage) to achieve the effects and is easier to achieve with it...

Put it in a global.css (or whatever name you want to call it) then add a statement like this in the head section of each content page:
<link rel="stylesheet" type="text/css" href="global.css" media="screen, print" />
campbells wrote: but i found out that wat ever i do in my other page , when run on my content page those linked page follow the content page setting.
Yes, because each page is independent and knows nothing about the other pages.
campbells wrote: actually is it possible i want to make like the footer style is different then the header and content page?
You can make styles apply to different classes like:
In css:
.header a { color: blue; }
.header a:hover { color: red; }
.footer a { color: green; }
.footer a:hover { color: yellow; }
In html:
<div class="header">
<a href="link1">Link 1</a>
</div>
<div class="footer">
<a href="link1">Link 1</a>
</div>
That's a very simple example. I suggest you google CSS or visit this site: http://www.csszengarden.com/[^]

hey guys, i am planning on driving into the world of html and web developement. i already have knowledge of HTML and can make basic sites and i know there a programs out there liek frontpage that can assist me also. My main purpose for this post is to find out a few things.
1. If i wana make a web-based database, do i need a hosting company to host it? or can i make the main computer in an office host it and people able ot access it when that computer is turned on?
2. If i get a hosting company and thier servers go bonkers, is it possible for them to lose all ym clients information??
3. and sites, links, or advice to help me design this?
Thank you all for any input

What do you mean by that - a database that you can access via the internet? If so, then most can be connected to via asp etc. You'd need to find a hoster with a SQL / Oracle / MySQL backend..
You COULD use a normal PC for the server, and no need to register a domain etc, but the problem with that would be that unless it has a static IP address, it will change regualrly, and people will need to be notified of the change
If the hosting co DOES go bonkers, they will more than likely have backups - check the SLA to make sure that restore times are acceptable for what you need to do.

Q(1)
I have created an array and store 3 functions in it. Eg.
this.validateCols = new Array();
this.validateCols[this.COST] = function(obj, index)
{
return 0;
};
this.validateCols[this.LOCKED] = function(obj, index)
{
return 0;
};
this.validateCols[this.COMPLETION] = function(obj, index)
{
return 0;
};
Calling validateCols[0](0, 0) works in IE, but in Firefox I get:
validateCols[0] is not a function
Is this the correct way to define functions in an array? Or is there a better way?
Or is this not supported at all in Firefox?
Q(2)
Also .swapNode() is not in Firefox? Any alternatives?
Q(3)
I implemented drag 'n' drop and it works in IE but not in Firefox.
Each droppable HTML TD element has:
ondragenter="this.parentNode.style.backgroundColor = 'gray'; window.event.returnValue = false;"
ondragover="window.event.returnValue = false;"
ondragleave="this.parentNode.style.backgroundColor = 'white'; window.event.returnValue = false;"
ondrop="OnDrop(this);"
Each draggable URL element has attributes:
id='draggable'
onmousemove='window.event.srcElement.dragDrop();'
ondragstart='window.event.dataTransfer.setData("text", "data");'
But this doesn't work in Firefox. Anyone got any ideas?

Storing functions in an array works just fine in Firefox. (I just tried it to be 100% certain.)
What are the values of this.COST, this.LOCKED and this.COMPLETION?
Also .swapNode() is not in Firefox? Any alternatives?
You have to do it using standard methods like cloneNode, addChild, removeChild, replaceChild, insertBefore.

There is no window.event object in Firefox. Instead the event object is sent as a parameter to the event method. You can put the event object in the event variable using this:
if (!event) event = arguments[0];
To use the object from either model just refer to "event". In IE this will refer to the window.event object as the window object is a default object:
event.returnValue = false;
---
b { font-weight: normal; }

I have read that there's a onDragDrop event in the standards W3C. However it only gives as much information as who the sender was. What I would like is to set up some data hence the usefulness of IE's dataTransfer object.
Am not sure whether it's possible to set up a 'text' type data (eg. "1234|Some code|Some type") during the drag, and then drop it onto a table row... in Firefox. I've googled and still no luck finding an alternative to IE's dataTransfer object.

My recommendation is to use one of myriads open-source javascript libraries out there that standardise all of these for you.
My favourite pick is Sarissa[^] for XmlHttpRequest (and other extra bits), and Scriptaculous[^] for DHTML effects.

I am quite disappointed in the drag 'n' drop support in Mozilla Firefox. What am trying to achieve is dragging an element from one IFRAME/FRAME into another IFRAME/FRAME. But upon dropping the element, I do not want the target IFRAME/FRAME to open/load it. I want it simply to handle the event, such as parsing the element/data dropped. Such uses as dropping an element into a table inbetween rows 2 & 3.
I have studied Netscapes way of ondragdrop events. However this only handles dropping external files, into the browser window, and the browser window will open/load the file. This is not what I want.
The only closest IE/FF drag'n'drop thing I found was http://script.aculo.us/ however their dragging doesn't go across IFRAME/FRAMEs.
Is there any way Firefox will implement similar drag'n'drop events as IE's:
ondragenter, ondragleave, ondragover, ondrop? that works across IFRAME/FRAMEs?

My Win2K installation has IIS 5.0 installed.
I installed the .Net Framework 2 but still my WebApps wont show server controls.
Can IIS 5.1 be installed on Win2000? If so, how?

AFAIK it's not possible.
What is the exact error that is displayed, anyway?

I think ASP.NET 2.0 does run on Win2K.
I'm sorry but I'm used to Windows Server 2003, so I can't tell.
Anyway, as other guys suggested, you should re-run aspnet_regiis -i to be sure ASP.NET is correctly registered in IIS.
