Get the GUID of a WebPart in SharePoint 2007

Question

I'm trying to emit some jQuery and other Javascript that will hide and show WebParts on a page. What I'd like to do is find one of two things:

• The ID of the table cell that contains the WebPart (i.e. MSOZoneCell_WebPartWPQ5)
• The WebPartID of the div tab of the WebPart that shows in the HTML (i.e. WebPartID="059611a7-adef-479e-bda9-fe5799dc62d1")

I've looked at the WebParts in the Zone I want to impact using the following code:

        System.Web.UI.WebControls.WebParts.WebPartZoneBase
        myZone = this.Zone;

        if (myZone != null)
        {

            for (int i = 0; i < myZone.WebParts.Count; i++)
            {
                // Get the web part
                System.Web.UI.WebControls.WebParts.WebPart wp =
                    myZone.WebParts[i] as System.Web.UI.WebControls.WebParts.WebPart;
                if (wp != null)
                {
                    // Build an XPath query to get the attribute for
                    // this web part
                    string xpathQuery = "/tabs/tab[@name='" + wp.Title + "']";

                    XmlElement wpElement =
                        tabConfigDoc.SelectSingleNode(xpathQuery) as XmlElement;

                    if (wpElement != null)
                    {                            
                        hideTabsJS.AppendFormat("$(\"#{0}\").hide(); ", wp.ID);
                        //switchTabsJS.AppendFormat("$(\"#{0}\").hide(); ", wp.ClientID);
                    }
                }
            }

The problem is that none of the APIs for the WebPart or WebPartManager seem to provide this information. Is it possible to derive one of the two IDs?

Answer 1

Just of curiosity, have you tried casting the web parts as Microsoft.SharePoint.WebPartPages.WebPart and accessing the ID from that?
