Introduction

In SharePoint 2010, the People Picker field is a powerful tool that allows users to select individuals from the organization's user directory. However, when you need to retrieve the email ID of the selected user, things can get a bit tricky. In this article, we will explore how to get the email ID from the People Picker field using Client-Side Object Model (CSOM) in a custom list form.

Understanding the People Picker Field

The People Picker field is a complex field that stores the display name and the login name of the selected user. When you select a user from the People Picker field, it returns the display name and the login name in the format domain\username. For example, if you select a user named John Doe, the People Picker field will return mydomain\johndoe as the login name.

Getting the Display Name from the People Picker Field

To get the display name from the People Picker field, you can use the PreSaveAction event in your custom list form. The PreSaveAction event is triggered before the form is saved, and it allows you to perform any necessary actions before the form is saved.

Here is an example of how you can get the display name from the People Picker field using the PreSaveAction event:

protected void ListForm_PreSaveAction(object sender, EventArgs e)
{
    // Get the People Picker field control
    SPFieldUserValueCollection peoplePickerField = (SPFieldUserValueCollection)ListForm.Fields["PeoplePickerField"].GetValueAsText();

    // Get the display name from the People Picker field
    string displayName = peoplePickerField[0].LookupValue;

    // Log the display name
    SPUtility.Log(displayName, "Display Name");
}

In this example, we first get the People Picker field control using the ListForm.Fields collection. We then get the display name from the People Picker field using the LookupValue property.

Getting the Email ID from the People Picker Field

Now that we have the display name from the People Picker field, we need to get the email ID of the selected user. To do this, we need to use the ClientContext object to query the user profile property.

Here is an example of how you can get the email ID from the People Picker field using the ClientContext object:

protected void ListForm_PreSaveAction(object sender, EventArgs e)
{
    // Get the People Picker field control
    SPFieldUserValueCollection peoplePickerField = (SPFieldUserValueCollection)ListForm.Fields["PeoplePickerField"].GetValueAsText();

    // Get the display name from the People Picker field
    string displayName = peoplePickerField[0].LookupValue;

    // Create a new ClientContext object
    ClientContext clientContext = new ClientContext("http://your-sharepoint-site-url");

    // Get the user profile property
    UserProfileManager userProfileManager = new UserProfileManager(clientContext);
    UserProfile userProfile = userProfileManager.GetUserProfile(displayName);

    // Get the email ID from the user profile property
    string emailId = userProfile.Email;

    // Log the email ID
    SPUtility.Log(emailId, "Email ID");
}

In this example, we first create a new ClientContext object using the URL of your SharePoint site. We then get the user profile property using the UserProfileManager class. Finally, we get the email ID from the user profile property using the Email property.

Putting it all Together

Now that we have the display name and the email ID from the People Picker field, we can put it all together to get the email ID of the selected user.

Here is an example of how you can put it all together:

protected void ListForm_PreSaveAction(object sender, EventArgs e)
{
    // Get the People Picker field control
    SPFieldUserValueCollection peoplePickerField = (SPFieldUserValueCollection)ListForm.Fields["PeoplePickerField"].GetValueAsText();

    // Get the display name from the People Picker field
    string displayName = peoplePickerField[0].LookupValue;

    // Create a new ClientContext object
    ClientContext clientContext = new ClientContext("http://your-sharepoint-site-url");

    // Get the user profile property
    UserProfileManager userProfileManager = new UserProfileManager(clientContext);
    UserProfile userProfile = userProfileManager.GetUserProfile(displayName);

    // Get the email ID from the user profile property
    string emailId = userProfile.Email;

    // Log the email ID
    SPUtility.Log(emailId, "Email ID");

    // Set the email ID as the value of the People Picker field
    ListForm.Fields["PeoplePickerField"].SetValueAsText(emailId);
}

In this example, we first get the display name from the People Picker field using the PreSaveAction event. We then get the email ID from the user profile property using the ClientContext object. Finally, we set the email ID as the value of the People Picker field using the SetValueAsText method.

Conclusion

In this article, we explored how to get the email ID from the People Picker field using CSOM in a custom list form in SharePoint 2010. We first got the display name from the People Picker field using the PreSaveAction event. We then got the email ID from the user profile property using the ClientContext object. Finally, we set the email ID as the value of the People Picker field using the SetValueAsText method.
