Adding Web Part to SharePoint Page using CSOM

In this blog, you will learn how to add web part to a page programmatically. CSOM approach is explained.

In this article, you will learn how to add web part to a page programmatically.

The web parts can be appended to a page using the webpart xml content. Each and every webpart present on SharePoint is represented by xml content. This can be witnessed by exporting the webpart from any page. In this article, you will learn how to add the webpart using CSOM approach.

The following denotes a content editor webpart xml content.

XML:

"<?xml version="1.0" encoding="utf-8"?>
<WebPart xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://schemas.microsoft.com/WebPart/v2">

</WebPart>

The following steps shown the implementation part.

• Using client context, try getting the page details using server relative url.
• If necessary, check out the file.
• With GetLimitedWebPartManager method, get the webpart details on the page.
• Check if the webpart already exists
• If not present, import the webpart xml (similar to the one shown above) and add it to the page

The following code snippet shows the CSOM code for the above implementation approach.

CODE:

var page = webpartContext.Web.GetFileByServerRelativeUrl("/sites/SPMySite/Person.aspx");
webpartContext.Load(page);
webpartContext.ExecuteQuery();
if (page.CheckOutType != CheckOutType.Online)
{
    // Check out
    page.CheckOut();
}
// Gets the webparts available on the page
var wpm = page.GetLimitedWebPartManager(PersonalizationScope.Shared);
webpartContext.Load(wpm.WebParts,
    wps => wps.Include(wp => wp.WebPart.Title));
webpartContext.ExecuteQuery();
var availableWebparts = wpm.WebParts;
// Check if the current webpart already exists.
var filteredWebParts = from isWPAvail in availableWebparts
where isWPAvail.WebPart.Title == Title
select isWPAvail;
if (filteredWebParts.Count() <= 0)
{
    // Import the webpart xml
    var importedWebPart = wpm.ImportWebPart(wpXML); //wpXML denotes the webpart xml file.
    // Add it to page
    var webPart = wpm.AddWebPart(importedWebPart.WebPart, Zone, 8);
    webpartContext.ExecuteQuery();
}

The webpart is successfully added to Person.aspx page. Try opening the page and check the webpart added. Any webpart type can be added to the page using the above approach. The appropriate webpart xml should be generated by the developer before adding it to the page.
