How do make the best colorpicker option ... hopefully with AJAX

M

Mikael Syska

Hi,

I have a problem ...:
If you look at http://syska.dk/upload/eb-14.jpeg you can see some names
to the right ... Alexandro, syska, resurrected.

I want an option to pick a new color for the name when clicking it.

I have a panel with 216 different colors, put into a <table>

But I can't figure out how to make it ... so that I know witch name was
clicked and still get the colorId ...

Also I want to have the "player list" in a updatePanel as I want to use
AJAX ....

I thought it was simple, but I can't figure out, how to do it ...

best regards
Mikael Syska

somthing like this, this will solve the clicnt side of the problem if I
understand it.
to send to the server can be solver by adding the values to a hidden field
and retrived on a future event, or you can send via the
ICallbackEventHandler. I have a sample on how to do this.

<head runat="server">
<title>Untitled Page</title>
<script language="javascript" type="text/javascript">
<!--

function window_onload() {
var tds =
document.getElementById('colorPicker').getElementsByTagName('TD')
for (i = 0;i<tds.length;i++){
tds.onclick = tabClick
}
}

function tabClick(){
var name = this.innerText
var bgColor = this.style.backgroundColor
alert(name)
alert(bgColor )
}

// -->
</script>
</head>
<body onload="return window_onload()">
<form id="form1" runat="server">
<div>
<table id="colorPicker">
<tr>
<td style="background-color :red;">c1
</td>
<td style="background-color:blue;">c2
</td>

<tr>
<td style="background-color:green;">c3
</td>
<td style="background-color:yellow;">c4
</td>
</tr>
</table>

Hi,

You are the man ... that solved the last part ... now I will look into
the link you sent ... which also seem to be the best idea with a web
service or some kind ... so I dont have to do full repost of the page,
if the user just want to change color ....

But what about security here ... ? Since I dont have the SesssionID or
anything at the webservice ?

would you just send it to the service, with some special random text
made at login time ... and also control the ip address .... ?

Hi again,

Maybe it was a little bit to fast explained.

I did the communication with the server via a webservice ... and it
works, but since I dont have access to the Session object in the
webservice, I can't do any authentication.

So ... will the Session object be available with the link you provided ?

Or are there some other smart way I can do it ?

Since later I will implement users ... I will have to know if there are
authenticated, so they can't change other users data ...

Yes it will work fine.

You might want to look up asp.net profiles to oraganize your user data.
it uses sql database to keep setting for users authenticated or not

Nice ...

As I can see it ... it aint possible to have more than one Async
callback per page or am I missing something here ?

Since the implementation of the interface also specify that is going to
happen as return value and input param ...

btw ... thanks very much for the help, it has solved my problem.

You can have as many as you want.

what I do is send a string with the "|" symbol as a separator

so I may have a string like this

"job1|value1|value2"

and from another event I may have

"job2|value1|value2|value3"

on the client side is split the string into array at the "|" symbol

the first value in the array "job1" or "job2" tells me what job needs doing

when I send back the result send it back the same way

"job1|result1|result2"

then I split it into a array on the client side using the first value to
identify the job again.
