ESPRsult webpart cannot be used in SharePoint Designer 2007

Oct 29, 2008 at 7:48 PM
I used SharePoint Designer to create a blanck ASPX page called mytest.aspx. Then I insert the web part ESPCoreResults. The page display the following error

DataSourceID is either missing or set to an empty string

I tried to access this page from browser: http://lngnpvappd016v/pages/mytest.aspx

I got the following error:

<title>Untitled 1</title> <form method="post" action="mytest.aspx" onsubmit="javascript:return WebForm_OnSubmit();" name="form1" id="form1">

Hi, it would be very kind if someone maybe from the dev team could give some input on this. I'm also stuck on that issue.
You can insert ESP Webparts with the Sharepoint browser integrated editor, but when you edit the page with the Designer, the webparts on the page get unusable.

Adding sample data to the webparts fixes this problem in SPD.

Or recompile the base class with

this.SampleData = "<All_Results>  <Result>    <workid>1</workid>    <rank>222</rank>    <title>Title of document or web page</title>    <author>Author of document or web page</author>    <size>1025</size>    <sitename></sitename>    <url></url>    <imageurl>/_layouts/images/aspx16.gif</imageurl><description>This is the summary of the document or web page. The summary is generated from the original document based on matches with query terms. In some cases, the summary is a description provided by the author.</description><write>December 26, 2004</write></Result></All_Results>";

in OnInit.

The larger problem seems to be with how SPD introduces whitespace into the Xsl attribute in the webparts.  Adding

                this.Xsl = this.Xsl.Trim();

right below the code previously entered sorts this one.
