Blazor Input Overview

    The Ignite UI for Blazor Input is a component where the user can enter data.

    Blazor Input Example


    To get started with the Input component, you first need to register its module.

    // in Program.cs file

    You will also need to link an additional CSS file to apply the styling to the IgbInput component. The following needs to be placed in the wwwroot/index.html file in a Blazor Web Assembly project or the Pages/_Host.cshtml file in a Blazor Server project:

    <link href="_content/IgniteUI.Blazor/themes/light/bootstrap.css" rel="stylesheet" />
    <IgbInput DisplayType="@InputType.Email" Label="Subscribe" Placeholder="" />

    Prefix & Suffix

    With prefix and suffix slots we can add different content before and after the main content of the Input. In the following sample we will create a new Input field with a text prefix and an icon suffix:

    Helper Text

    The helper-text slot provides a hint placed below the Input. Let's add some helper text to our phone Input:

    Input Sizing

    We can allow the user to change the size of the IgbInput using the --ig-size CSS variable. То do this, we will add some radio buttons to display all size values. This way whenever one gets selected, we will change the size of the Input:

    In the sample above we have demonstrated the use of the following attributes:

    • required - Used to mark the input as required
    • disabled - Used to disable the input
    • readonly - Used to mark the input as readonly


    The Input component exposes CSS parts for almost all of its inner elements. The following table lists all CSS parts exposed by the Input:

    Name Description
    container The main wrapper that holds all main input elements.
    input The native input element.
    label The native label element.
    prefix The prefix wrapper.
    suffix The suffix wrapper.
    helper-text The helper text wrapper.
    igc-input::part(input) {
        background-color: rgb(169, 214, 229);
        border-color: rgb(42, 111, 151);
    igc-input::part(label) {
        color: rgb(1, 42, 74);
    igc-input::part(suffix) {
        color: white;
        border-color: rgb(42, 111, 151);
