Microsoft Dynamics 365: How to Remove Unwanted Special Characters from Text Fields

Microsoft Dynamics 365 has a flexible and extendable architecture, and can be integrated with other platforms. In integrations, it is common for data entered in Dynamics 365 to be shared with other platforms. Although Dynamics 365 text fields are flexible to save special characters, other platforms, that integrate with Dynamics 365, may not be as flexible. For example, when you integrate Dynamics 365 with SharePoint or One Drive, you may want to use the record’s name in Dynamics 365 to create the record’s document set or folder in SharePoint or One Drive . In such a case, Dynamics 365 fields being used by SharePoint or One Drive have to adhere to those platforms’ more restrictive special characters restrictions. The the invalid characters for OneDrive, OneDrive for Business on Office 365, and SharePoint Online are ” * : < > ? / \ | and for OneDrive for Business on SharePoint Server 2013 they are ~ . ” # % & * : < > ? / \ { | }.

The plugin in this post addresses this integration challenge by preventing users from saving restricted special characters in the text field(s) enabled text validation. When creating or updating a record in Dynamics 365, the plugin will check the text field(s), enabled for text validation, and strip out the characters that are not part of the permitted list characters.

To demonstrate this plugin’s functionality, we enabled text validation on the Account Name field for the Account entity. The validation rule applied by the plugin is: the Account Name field is only permitted to take in alphanumeric characters, space and 2 special characters i.e. underscore and hyphen. If a user enters any characters in the field, other than the permitted list of characters, they will be stripped out when they save the record. In the image below, a user entered both valid and invalid characters. Before Save:
Before Saving, user has entered invalid special characters

When saving the record, the plugin stripped out the invalid characters from the text field, leaving only the permitted characters (i.e. alphanumeric characters, space and 2 special characters i.e. underscore and hyphen). After Save:
After Saving, invalid special characters are removed

Microsoft Dynamics 365: The Complete Guide to Getting and Setting Fields Using a Plugin

When extending the Microsoft Dynamics 365 platform, there is often a need to retrieve and/or set field values. In this post, we will cover how to get and set values for the Microsoft Dynamics 365/CRM platform fields using a plugin, developed using the Microsoft C# programming language. You can also develop plugins and perform the operations demonstrated in this post using other .Net platform-supported programming languages. In Dynamics 365, you can create the following types of fields (or datatypes): Single Line of Text, Option Set, MultiSelect Option Set, Two Options, Image, Whole Number, Floating Point Number, Decimal Number, Currency, Multiple Lines of Text, Date and Time, Lookup and Customer.
