RegisterClientScriptBlock problems

Question

Hello, I am attempting to use RegisterClientScriptBlock and it is not seeming to work. Can someone take a look at my code?

Here is my C# (which I have in my PageLoad)

 
var videoLoadScript = " var so = new SWFObject('player.swf','mpl','955',' 540','9');";

videoLoadScript += "so.addParam('allowscriptaccess','always');";

videoLoadScript += "so.addParam('allowfullscreen','true');";

videoLoadScript += "so.addParam('flashvars','&file='" + path + "'&autostart=true');";

videoLoadScript += "so.write('player');";

ClientScript.RegisterClientScriptBlock(this.GetType(), "test", videoLoadScript, true);

Here is my HTML (which I have in my BODY tag):

 
<div id="player" oninit="test();" align="center">This text will be replaced</div> 
 

does anyone see anything obviously wrong?

here is code that actually works.....and there is no HTML code StringBuilder sb = new StringBuilder(); sb.Append(" "); sb.Append("var vReturnValue = window.showModalDialog('TubeColorAssignment.aspx','','status:no;center:yes;dialogWidth:500px;dialogHeight:300px;help:no;scroll:no');"); sb.Append("if (vReturnValue)"); sb.Append("{"); sb.Append("window.location.href = window.location.href"); sb.Append("} sb.Append("/script>"); if (!ClientScript.IsClientScriptBlockRegistered("TubeColorPopup")) { ClientScript.RegisterClientScriptBlock(this.GetType(), "TubeColorPopup", sb.ToString()); } try making yours similar, but of course replacing my script code with yours. see if that works.

no. you are not suppose to. You can do javascript in two ways: 1. writing the javascript functions in the page source. 2. writing the javascript function in the code behind using RegisterClientScriptBlock you don't need to do both.

Now, when you view your source can you see your javascript function?

Try this: StringBuilder sb = new StringBuilder(); sb.Append(" "); sb.Append("var so = new SWFObject('player.swf', 'mpl', '955', '540', '9');"); sb.Append("so.addParam('allowscriptaccess', 'always');"); sb.Append("so.addParam('allowfullscreen', 'true');"); sb.Append(String.Format("so.addParam('flashvars', '&file='{0}'&autostart=true');", path)); sb.Append("so.write('player'); sb.Append("/script>"); if (!ClientScript.IsClientScriptBlockRegistered("Player")) { ClientScript.RegisterClientScriptBlock(this.GetType(), "Player", sb.ToString()); }

if you use RegisterClientScriptBlock, you don't need javascript on the client-side. .Net will run the javascript code without the client-side having any javascript. my script works just fine without ANY javascripting on the client-side/page source/HTML.

Thank you for your help, I tried that and got the same result. When I looked at the page source there was no javascript there! stinks :(
