Problem when generating Client Side Script.

[John Owens]

I use in Render( HtmlTextWriter output) :

//--------------------------------------------------------------------------

output.WriteBeginTag( "a" );

if( ID != null )

output.WriteAttribute( "id", ClientID );


output.WriteAttribute( "href", "javascript:" +
Page.GetPostBackEventReference( this ) );

output.Write( HtmlTextWriter.TagRightChar );

if( Text.Length > 0 )

output.Write( Text );

output.WriteEndTag( "a" );



//--------------------------------------------------------------------------
-------------------------

This creates the HTML:

<a id="WebLinkButtonCtrl1"
href="javascript:__doPostBack('WebLinkButtonCtrl1','')">Type something
here</a>

The problem is when I press the button as it gives a:

Microsoft JScript runtime error: Object expected

Does anyone have any ideas as how to solve this as it appears to be
happening whenever I use

output.WriteAttribute( "href", "javascript:" +
Page.GetPostBackEventReference( this ) );

even when they are copied from samples etc.



Thanks

John.

It was because the control wasn't inside the form tag.

Does anyone know why this is the case?

Hi,

I haven't check your code, but one thing I can be sure of, the controls
should be inside a form.


cheers,
