Text Input Components

Warning

Text input components can only be used in modals.

Text input components are a type of MessageComponents that can only be used in modals. Texts inputs can be longer (the Paragraph) style or shorter (the Short style). Text inputs have a variable min and max length.

Creating text inputs

Text input components can be built using the TextInputBuilder. The simplest text input can built with:

var tb = new TextInputBuilder()
    .WithLabel("My Text")
    .WithCustomId("text_input");

and would produce a component that looks like:

Additional options can be specified to control the placeholder, style, and min/max length of the input:

var tb = new TextInputBuilder()
    .WithLabel("Labeled")
    .WithCustomId("text_input")
    .WithStyle(TextInputStyle.Paragraph)
    .WithMinLength(6)
    .WithMaxLength(42)
    .WithRequired(true)
    .WithPlaceholder("Consider this place held.");
