I am having trouble accessing the GetPosition() from the server side.

If I display it in a messagebox, it works, but I can't doesn't set my hidden field properly.

This is the example that works:
Javascript Code:
function GetPositionLeft() {
var pos;
pos=ASPNetMedia.FlashVideo("FlashVideoLeft").GetPosition();
alert(pos);
}

This is the example that does not work:
On ASP.NET User Control (ascx file):
<asp:HiddenField ID="hiddenfield" runat="server" />

Javascript Code:
function GetPositionLeft() {
var pos;
var hidden = document.getElementById('hiddenfield');
pos=ASPNetMedia.FlashVideo("FlashVideoLeft").GetPosition();
alert(hidden.value);
}


Please help. I have tried several different ways and can't seem to find a way to access any ASP.NET controls from javascript or access any Javascript variables from the server side. I need to be able to access the position and set the position initiated from a C# procedure.

Thanks!

Now I have this:

ASPNetMedia.FlashVideo(\"FlashVideoLeft\").OnProgress = function(object, position){
var txt=document.getElementById("txtPosition");
txt.value=position;
}

It still isn't working. Can you point me in the right direction?

Actually, the backslashes are not there. This is my code that is not working:
ASPNetMedia.FlashVideo("FlashVideoLeft").OnProgress = function(object, position){
var txt=document.getElementById("txtPosition");
txt.value=position;
}

The SDK (from your downloads page) has a page with examples of all the JavaScript API functions.

No idea. Thts why i asked if there were errors in your error console:

How about this:

ASPNetMedia.FlashVideo("FlashVideoLeft").OnProgress = function(object, position){
alert(position);
}

I finally got it. Apparently, in order for the Javascipt to write the value to the textbox, it needs to be injected at runtime by getting the Textbox's ClientID from the web form. The working code is below:

StringBuilder strScript = new StringBuilder();
strScript.AppendLine("<script>ASPNetMedia.FlashVideo(\"FlashVideoLeft\").OnProgress = function(object, position){");
strScript.AppendLine("document.getElementById('" + this.txtPosition.ClientID + "').value=position;}</script>");



Page.ClientScript.RegisterStartupScript(this.GetType(), "JavaScript", strScript.ToString() , false);


Thanks.
