• @System.ComponentModel.DescriptionAttribute

[DisplayName("Name of the Demo")]
[Description("Most items can have a display name and a description. This is the description text.")]
public string DemoName { get; set; } = "GenericEdit Demo";

When no DisplayName atttribute is specified, a displayname will be generated from the property name by spliting the property name from capitalization.

To not show a display name, provide an empty string:

[DisplayName("")]
[Description("This property has an empty display name.")]
public string TextWithEmptyDisplayName { get; set; }

Text Input

Basic Text

A string property will cause a simple text input to be generated.

[DisplayName("Name of the Demo")]
public string DemoName { get; set; }

Password

Adding the IsPasswordAttribute to a string property will create a password input:

[DisplayName("Password Field")]
[Description("Just requires adding the IsPasswordAttribute to a string property.")]
[IsPassword]
public string PasswordValue { get; set; }
