Hi All,

We faced one very wired issue and finally solved it. So thought to share 🙂 It took lots of mine time and research.

Use Case: In SharePoint online classic mode when we need to create new page using our custom page layout, we need OOBweb part (In our case Contacts webpart, here any web part will work) should be available by default on the page.

Background: We have migrated our SharePoint 2013 on-premises site to SharePoint online in classic mode. In SharePoint 2013 we were using feature to associate the web parts to our custom page layouts. So when new pages are created using our custom page layouts those web parts were appearing on the page.

But then this become challenge after migration to SharePoint online in classic mode. We don’t have feature option in SharePoint online. So we have option of editing the page layout adding web part in it and trying. This took the time for me and bit research. Googled bit but no luck soon.

Solution: After bit googled and lots of trial error with page layout, finally found the way.

Here we will take example of Contacts web part since we need to add Contacts web part on our news pages.

We have ContactFieldControl available in Microsoft.SharePoint.Portal assembly and namespace is Microsoft.SharePoint.Portal.WebControls

so we need to add register tag for this assembly in page layout as

<%@ Register TagPrefix="SharePointPortalWebControls" Namespace="Microsoft.SharePoint.Portal.WebControls"
    Assembly="Microsoft.SharePoint.Portal, Version=14.0.0.0, Culture=neutral, PublicKeyToken=71e9bce111e9429c" %>

Now we need to add WebPartZone in page layout. WebPartZone is available in Microsoft.SharePoint assembly and namespace in Microsoft.SharePoint.WebPartPages

so we need to add register tag for this assembly in page layout as

<%@ Register TagPrefix="WebPartPages" Namespace="Microsoft.SharePoint.WebPartPages"
    Assembly="Microsoft.SharePoint, Version=14.0.0.0, Culture=neutral, PublicKeyToken=71e9bce111e9429c" %>

Then we will add web part zone in page layouts as

<WebPartPages:WebPartZone runat="server" Title="Related webpart zone" ID="Related"></WebPartPages:WebPartZone>

Finally, we need to add ContactsField webpart in above webpart zone as

<WebPartPages:WebPartZone runat="server" Title="Aiheeseen liittyvää -WWW-osa-alue" ID="Related">
            <SharePointPortalWebControls:ContactFieldControl webpart="true" runat="server" 
                __WebPartId="{803C1870-1A38-4946-9CAA-C85707B1E18D}"
                Title="Contact Details"
                Description=""
                PartOrder="2"
                ID="ContactFieldControl1"
                ChromeType="TitleOnly">
            </SharePointPortalWebControls:ContactFieldControl>
            </WebPartPages:WebPartZone>

Uploaded our page layout in masterpages gallery and tried by creating new page. It worked like charm 🙂 Existing pages also updated. On all existing pages as well ContactField webpart get added.

Thanks for reading 🙂
