Programmatically changing user control content

I'm trying to write a method that will look into the custom controls we have in our pages and replace certain pieces of text.  With the code below, I seem to be able to get to the container but not the control.

Can you please let me know where I'm missing it?

CmsManager cmsManager = new CmsManager();
 
foreach (ICmsWebControl control in page.Controls)
    if (control.ControlType == typeof(Telerik.Cms.Engine.WebControls.GenericContent))
    
        Telerik.Cms.Engine.WebControls.GenericContent goControl = control.LoadControl(this) as Telerik.Cms.Engine.WebControls.GenericContent;
 
        if (goControl.Content.Contains("ReplaceMe"))
        
            goControl.Content = goControl.Content.Replace("ReplaceMe", "newText");
 
            cmsManager.SaveControl(control);
        
    

Thanks,
-Jason

Hi Jason,

This looks like as a code for Sitefinity 3.x edition. Please check this article . You should work with staged version of the page and you should better specify a container. If you do not make an automated tool you can query the following tables of the database

For public controls like GenericContent you have to update [sf_CmsControlProperty] table.
For backend - modules you have to update -[sf_CmsTextContent]

Ivan,

Thank you for your reply.  I tried using that code earlier and the trouble with it and with my code is that this line :

Telerik.Cms.Engine.WebControls.GenericContent gcCtrl = webCtrl.LoadControl() as Telerik.Cms.Engine.WebControls.GenericContent;

returns nothing - and I don't know why.  I tried using the example you referenced but I ran into the same result.
Here is the code as it stands, I'm not using the currentNode as in the example, I allow the user to select a parent page and then I change everything in that pagegroup.  Also I'm not calling page.publish() because I read that SavePage(page) was more efficient.

01.protected void FindAndReplace(Guid parentPage)
02.
03.    CmsManager cmsManager = new CmsManager();
04.    // Gets all child pages of page
05.    IList childPages = cmsManager.GetPages(parentPage);
06.    string pageName = string.Empty;
07.    foreach (ICmsPage cmsPage in childPages)
08.    
09.        ICmsPage page = (ICmsPage)cmsManager.GetPage(cmsPage.ID, true);
10.        // If group page get child pages
11.        if (cmsPage.Pages.Count > 0 || cmsPage.PageType == CmsPageType.Group)
12.        
13.            this.FindAndReplace(page.ID);
14.        
15.        else
16.            if (this.ReplacePhraseInPageProperties(cmsPage))
17.            
18.                cmsManager.SavePage(cmsPage);
19.            
20.        
21.    
22.
23.private bool ReplacePhraseInPageProperties(ICmsPage page)
24.
25.    bool modified = false;
26.    if (page.Title.IndexOf("find") > -1)
27.    
28.        page.Title = page.Title.Replace("find", "replace");
29.        modified = true;
30.    
31.    if (page.MenuName.IndexOf("find") > -1)
32.    
33.        page.MenuName = page.MenuName.Replace("find", "replace");
34.        modified = true;
35.    
36.    if (page.Description.IndexOf("find") > -1)
37.    
38.        page.Description = page.Description.Replace("find", "replace");
39.        modified = true;
40.    
41.    if (page.Name.IndexOf("find") > -1)
42.    
43.        page.Name = page.Name.Replace("find", "replace");
44.        modified = true;
45.    
46.    // create a new instance of CmsManager
47.    Telerik.Cms.CmsManager cmsManager = new Telerik.Cms.CmsManager();
48.    // we are going to use Controls collection of a staged version of a page to
49.    // access all controls of current page
50.    IList<Telerik.Cms.ICmsWebControl> pageControls = page.Staged.Controls;
51.    // to each Generic Content control in SideBarContent we are going to append "[Obsolete]" text
52.    foreach (Telerik.Cms.ICmsWebControl webCtrl in pageControls)
53.    
54.        if (webCtrl.ControlType == typeof(Telerik.Cms.Engine.WebControls.GenericContent))
55.        
56.            // the following line clearly demonstrates the difference between ICmsWebControl (any control that exists on the Sitefinity page)
57.            // and the actual control this ICmsWebControl carries. We have checked if ControlType of webCtrl is GenericContent, but to get
58.            // the actual instance of GenericContent control, we need to call the LoadControl() function of ICmsWebControl. You can think
59.            // of ICmsWebControl objects as Sitefinity wrapper for the actual control
60.            Telerik.Cms.Engine.WebControls.GenericContent gcCtrl = webCtrl.LoadControl() as Telerik.Cms.Engine.WebControls.GenericContent;
61.            if (gcCtrl != null)
62.            
63.                if (gcCtrl.Content.Contains("find"))
64.                
65.                    gcCtrl.Content = gcCtrl.Content.Replace("find", "replace");
66.                    cmsManager.SaveControl(webCtrl);
67.                    modified = true;
68.                
69.            
70.        
71.    
72.    // finally we need to publish the current page and refresh it to see the results
73.    return modified;
74. 

Looking at this, can you see why it doesn't work?

Hi Jason,

Could you verify that the control of type GenericContent is found on the page? I checked the code on a sample page and it works properly at my end.
