Increase Text Box Character Limit to Over 100

Overview

In M-Files, the 'Text' data type is limited to 100 characters. The 'Text (multi-line)' can go to 10,000 characters but is not a single line. Not as useful for URLs or Title properties.

Solution

To increase the limit on the single line 'Text', you instead use a 'Text (multi-line)' and set it to a single line using a Metadata Card Configuration Rule.

1. Go to M-Files Admin->Metadata Structure (Flat View)->Property Definitions
2. Create or modify your text property to use the data type Text (multi-line).
3. Go to M-Files Admin -> (Your Vault)->Configurations->Metadata Card->Configuration->Rules->Behavior->Properties->Property Behavior 
4. Create a rule that sets the behavior of the property created in step 1, to 'Single Line' = 'Yes' (in the example below the property created was named "LongText" but for your rule, you will enter the name of the property that you want to increase the character limit for. 
5. Because the rules run sequentially, right-click on the rule and select "Move to Top". This will cause the rule to run before any other rule that could or would modify that property.
