Add rendering to the existing page and change the datasource using Powershell Script in Sitecore

  This blog can help you to work with Sitecore CMS and work with PowerShell script more efficiently. The following code snippet will be used to add rendering to the page and change the datasource to the rendering programmatically using the PowerShell script.

This code should work with any version of Sitecore. 

Open - Development Tools -> PowerShell ISE and paste the following code.

Modify the paths and fields according to your template fields.

1. Add rendering to the existing page

    PowerShell script code:

$RenderingItem = Get-Item -Path (@{$true="$($masterdatabase):\sitecore\layout\Renderings\Feature\SubHeader";$false="$($masterdatabase):\content"}[(Test-Path -Path "$($masterdatabase):\content\home")])
$DatasourcePath = Get-Item -Path (@{$true="$($masterdatabase):\sitecore\content\AKWeb\Shared\Datasources\SubHeader\SubHeader";$false="$($masterdatabase):\content"}[(Test-Path -Path "$($masterdatabase):\content\home")])
$placeholderH = "header"
#Find the rendering item and convert to a rendering
