I need to change the background color of an asp.net textbox every 15 seconds. Can anyone please provide a detailed code sample of how to accomplish this?

Thank You.....Franco

You'll have to do this in JavaScript by using a Timer...

Thanks ca8msm

I have java script code to do just that. Can you give me a DETAILED sample of how to weave java script into the vb.net code on an asp.net page? I've never had to do that prior to this.

Thanks.....Franco

It's exactly the same as if it were a HTML page. Insert your script into the HTML document, and call the function on the body onload event.

like ca8msm said, ur JS will NOT interact with the .NET coding...

ca8msm & vbkris

I pasted my java script into the aspx page and I'm getting the following message when I attempt to open it:

Cannot use 'JavaScript' because another language has been specified earlier in this page.

Can you provide a sample of using java script with VB.net in the same aspx?

Thank You...Franco

Just paste it into the <head> section e.g.
Code: 
<head runat="server">
    <title>Untitled Page</title>
    <script type="text/javascript">
        function testFunction()
        {
            document.getElementById("TextBox1").value = 'hello';
        }
    </script>
</head>

Here is the whole page which I developed in notepad. Please see below at which point I need to RUN THE JAVA SCRIPT code:

ca8msm:
>> document.getElementById("TextBox1").value = 'hello';

would really depend upon the clientID of the textbox. it may not necessarily work in all situations, thats why i asked him the .NET version so that he can output the correct clietn Id to the JS file.

i usually use the Page.RegisterStartupScript to do it, if its .NET 2 then there is a different object to do this.


vedicman:
anyways where exactly have u called the function window_onload().
one more thing, could u give me a "view source" of the ASP.NET, that would be even better...

All of the code is pasted above. What I'm trying to do here is to consolidate 2 pages into one. One page is an aspx that does some calculations. The second page is an html page with Java Script. The problem with that is that I must first run the aspx to do the calculations, then copy the results from a text box and hard code that into the java script.


I also have a link on my aspx that opens the html page, but agin I must first hard code into my java script to make it useful. Is there a way to pass in the contents of the asp.textbox to the java script on the html page? If so, that may be the easiset way to do it. If you know how to do that please show me how to do it.

Thanks....Franco

It doesn't make a difference which version of the framework the poster is using with regards to the clientid and that was just an example of how to put a javascript function into a page (which is what the poster asked). I could have wrote anything in that function...

oh, the version is NOT for the ClientId, its for the command that will output the JS.

e.g.:
in .NET 1.1 we would use
Page.RegisterClientScript("ClientTxtObject","<script>theTxtBox=document.forms[0]." & txt1.clientID & "</script>")

in .NET 2 there is a special object for handling JS itself if i am correct. its only for this that i required the code.

ok, i will assume its .NET 1.1

e.g.:
Page.RegisterClientScript("ClientTxtObject","<script>theTxtBox=document.forms[0]." & txt1.clientID & ";setTimeout('changeColors()',15000)</script>")


in the ASPX file:
<script>
//Color array:
var addCol=new array()
arrCol[0]="red"
arrCol[1]="green"
var currentColor=0
function changeColors()
{
theTxtBox.style.bgColor=arrCol[currentColor]
currentColor++
if(currentColor>=arrCol.length)
currentColor=0

setTimeout('changeColors()',15000)
}
</script>

The only difference between framework versions in this case is that RegisterClientScript has been moved to the ClientScript class (although Page.RegisterClientScript will still work) and is irrelevant in this case as the client id will always be the same.

>>and is irrelevant in this case as the client id will always be the same

maybe, but again, i thought it was better to warn the poster regarding the same. cause it may not work in other situations, like the txtbox could be inside a datagrid (or) a usercontrol etc.

>>The only difference between framework versions in this case is that RegisterClientScript has been moved to the ClientScript class

bingo! i required that info so that i could give an example to the poster, thats all...

Hello

I've have got it working more or less, but there is still a small glitch. The first color in the sequence displays briefly, then the backcolor goes white again, then the colors display in sequence for 5 seconds each as they are supposed to do. I will paste the entire code below, and I'm hoping that someone will paste it into notepad and give it an aspx extension and run it to experience the glitch noted above. Hopefully someone can then show me how to go straight into the color sequence without the initial glitch.

Thanks for helping thus far. Your insights are appreciated:
