SharePoint Online: Working With List Fields Using PowerShell

In this article we will discuss the operations on List Fields (Columns), which involves Getting All Columns, Adding New Columns, Updating Existing Columns and so on.

To start with this demo we will start with a list called “Products” and perform all operations on this list.

1

Operation: How to Add New Columns To List

We can add a new column to the list by making use of the following code.

2

In Step 1 we will get the object reference to the current Web using Client Context properties

In Step 2 we will get the object reference to the respective list by calling “GetByTitle” method

In Step 3 we will define the xml of the List Column schema. You can get this XML by prototyping the list using SharePoint UI and then by using SharePoint Client Browser to look for Schema XML for Lists & Fields.

In Step 4 we will call “AddFieldAsXml” method to add field as xml schema to the list

In Step 5 we will send the batch request to SharePoint Server for processing by calling “ExecuteQuery” method

In Step 6 we will display the success message to the users

In Step 7 we will call function that we have explained in Step 1-5

We can see this field added to the list by browsing the list

4

We can see the details of the new column (Datatype and others) by browsing List Settings

5

Operation: How Get All Columns of List

We can get all columns used in a list by making use of the following code.

6

In Step 1 we will get the object reference to the current Web using Client Context properties

In Step 2 we will get the object reference to the respective list by calling “GetByTitle” method

In Step 3 we will get the object reference to Fields collection of the list

In Step 4 we call the “Load” function to retrieve Fields collection properties from server

In Step 5 we will send the batch request to SharePoint Server for processing by calling “ExecuteQuery” method

In Step 6 we will loop through the collection and display Field details to the users

In Step 7 we will call function that we have explained in Step 1-6

We can see the fields collection to the list by browsing the list

7

Operation: How to Update column of List

Let’s consider that we have to add little description the field Title, which is blank currently

8

We can update an existing column to the list by making use of the following code.

9

In Step 1 we will get the object reference to the current Web using Client Context properties

In Step 2 we will get the object reference to the respective list by calling “GetByTitle” method

In Step 3 we will get the object reference to the respective field by calling “GetByTitle” method

In Step 4 we will set the Description property of List object with the required value

In Step 5 we will call “Update” method to save these changes back to SharePoint List

In Step 6 we will call “Load” method to retrieve updated properties (Description) of the field from Server

In Step 7 we will send the batch request to SharePoint Server for processing by calling “ExecuteQuery” method

In Step 8 we will display Field details to the users to the users

In Step 7 we will call function that we have explained in Step 1-8

10

We can see description of Title field is update to the list by browsing the field properties under list settings

11

Operation: How To Add Existing Site Columns To List

Since we are planning to add an existing Site Column to the list, it is necessary to ensure the existence of Site Column. We can verify this by navigating “Site Settings > Site Columns”.

For this demo I already have added a Site Column “ProductOwner” that we can see under “Custom Columns” group as shown below-

12

And we can also verify the list settings to ensure that “ProductOwner” Column is not added to the list earlier

13

Now we will look into code to add existing Site Column to the list as explained below-

14

In Step 1 we will get the object reference to the current Web using Client Context properties

In Step 2 we will get the object reference to the respective list by calling “GetByTitle” method

In Step 3 we will get the object reference to Fields collection of the Web. It is important to note that Site Columns are the part of Web Fields Collection not List Fields Collection. So we have to make use of Web object reference to look for existing Site Columns.

In Step 4 we call the “Add” function on “Fields” Collection of the list to add the reference of the Site Column from Step 3

In Step 5 we will send the batch request to SharePoint Server for processing by calling “ExecuteQuery” method

In Step 6 we will call function that we have explained in Step 1-5

We can see the field collection to the list by browsing the list settings-

16

We can further look into column details by clicking it

17

Operation: How Set Default Value For Field

We can set default values to SharePoint List Fields programmatically by using the following code as explained below-

18

In Step 1 we will get the object reference to the current Web using Client Context properties

In Step 2 we will get the object reference to the respective list by calling “GetByTitle” method

In Step 3 we will get the object reference to Fields collection of the list

In Step 4 we will call “DefaultValue” property of Field Object and assign it a value of our choice

In Step 5 we will call “Update” method of Field Object, which will update the “DefaultValue” property back into database

In Step 6 we will send the batch request to SharePoint Server for processing by calling “ExecuteQuery” method

In Step 7 we will display the a success message which is informing users about the status of operation

In Step 8 we will call function that we have explained in Step 1-7

19

We can see this value shown as default value whenever a new Item has been created (programmatically or using browser) as shown below-

PowerShell Automation: How To Send Email with HTML Body Containing Inline Images

During of a recent assignment I get across an automation requirement to send formatted emails daily to a set of users.

The email content involved the HTML formatting with lot of images as a part of layout. I have appointed PowerShell as automation technology to get this done.

I found worth writing a small article to explain the code (which is interesting) to embed images with in outgoing email content.

Now to start with demo, say we have to send an email with Health of Weekly Sales Card for an online shopping store every week on Monday.

This email would look like the one in the following screen shot:

1

In Step 1,2,4 we are defining HTML that will be send as Email Content.

Here it is very important to notice the “SRC” Tag where we are specifying image path not as actual path but as a Content Identifier that is mapped to the path of the attachment added to the Email.

And this is the trick that you have to remember to get the images embedded into the html body of the email.

234

Now once we are done with defining body content for Email Body, we can start configuring SMTP Client and adding the attachments to the email

In Step 5 we will initialize “SMTP Server”, “Mail Message”, and “SMTP Client” Objects

In Step 6 configure “From” & “To” Email IDs for the intended recipients. Also specify the “Subject” & “Body” for the email

5

In Step 7 & 8 we will add attachments to the Email and provide each attachment a Content Identifier (remember we used this identifier in “SRC” Tag while defining HTML content for the body)

Attachments can be added to the email by using object of “Attachment” Class.

While initializing the “Attachment” Object we have to provide actual path of the attachment as input parameter

Then we have to make sure that

  1. “Inline” property should be set to “True”,
  2. “DispositionType” property should be set to “Inline”,
  3. “MediaType” property should be set to “<type of content, you are attaching>”,
  4. “ContentId” property should be set to any unique Content Identifier to represent the attachment uniquely

67

In Step 9 we will send the email by call in “Send” method of SMTP Client object. Make sure to dispose the “Attachments” & “Mail Message” objects

8

And finally we will call the Send-Email Function in Step 10 to run all the code snippets described earlier

9

That is all for this demo.
