Question

As the question says – is there a way to determine which pages are including my web part?

Answer 1

If you’re looking for code, I’ve got something for you. If you’d like to find all Content Query web parts then you would call my code like this:

FindWebPart('http://server.com/', 'Microsoft.SharePoint.Publishing.WebControls.ContentByQueryWebPart'); 

Here’s the code:

public static void FindWebPart(string siteCollectionUrl, string webPartName) {     using (SPSite siteCollection = new SPSite(siteCollectionUrl))     {         using (SPWeb rootSite = siteCollection.OpenWeb())         {             FindWebPartHelper(rootSite, webPartName);         }     } }  public static void FindWebPartHelper(SPWeb site, string webPartName) {     // Search for web part in Pages document library     SPList pagesList = null;     try     {         pagesList = site.Lists['Pages'];     }     catch (ArgumentException)     {         // List not found     }      if (null != pagesList)     {         SPListItemCollection pages = pagesList.Items;         foreach (SPListItem page in pages)         {             SPFile file = page.File;             using (SPLimitedWebPartManager mgr = file.GetLimitedWebPartManager(PersonalizationScope.Shared))             {                 try                 {                     SPLimitedWebPartCollection webparts = mgr.WebParts;                     foreach (System.Web.UI.WebControls.WebParts.WebPart wp in webparts)                     {                         // Here perform the webpart check                         // For instance you could identify the web part by                         // its class name                          if (webPartName == wp.GetType().ToString())                         {                             // Found a match! Now do something...                             Console.WriteLine('Found web part!');                         }                     }                 }                 finally                 {                     // Needs to be disposed                     mgr.Web.Dispose();                 }              }         }     }      // Check sub sites     SPWebCollection subSites = site.Webs;     foreach (SPWeb subSite in subSites)     {         try         {             FindWebPartHelper(subSite, webPartName);         }         finally         {             // Don't forget to dispose!             subSite.Dispose();         }     } } 

Ofcourse you can make little changes to this code. Currently it does a string comparison, but it’s easy to do it in a more typed way. Have fun!
