Add a Button to a Project

Follow the steps below to add the Button component to an application:

Create a Blazor Server or Blazor WebAssembly application.
Add the <DxButton/> markup to a .razor file.
Configure the component: specify the button’s content and appearance, handle button clicks, and so on (see the sections below).

API Reference

Refer to the following list for the component API reference: DxButton Members.

Static Render Mode Specifics

Blazor Button does not support static render mode. Enable interactivity to use the component in your application. Refer to the following topic for more details: Enable Interactive Render Mode.

Button Content and Appearance

Use the Text property to specify the button’s text.

To configure button appearance, specify the RenderStyle and RenderStyleMode properties.

razor

<DxButton RenderStyle="ButtonRenderStyle.Primary" RenderStyleMode="ButtonRenderStyleMode.Contained" 
    Text="Primary (Contained)" />
<DxButton RenderStyle="ButtonRenderStyle.Danger" RenderStyleMode="ButtonRenderStyleMode.Outline" 
    Text="Danger (Outline)" />
<DxButton RenderStyle="ButtonRenderStyle.Link" RenderStyleMode="ButtonRenderStyleMode.Contained" 
    Text="Link" />

Assign the icon’s CSS class to the IconCssClass property to add an icon to your button. The IconPosition property specifies the icon position.

Razor
CSS

razor

<DxButton RenderStyle="ButtonRenderStyle.Dark" 
          Text="Undo" Title="Undo the last action." 
          IconCssClass="undo" />
<DxButton RenderStyle="ButtonRenderStyle.Dark" 
          Text="Redo" 
          Title="Restore the previously undone action." 
          IconCssClass="redo" 
          IconPosition="ButtonIconPosition.AfterText" />

css

.undo {
    width: 16px;
    height: 16px;
    background-image: url("../images/undo.svg");
    margin: 0 8px 0 0;
}
.redo {
    width: 16px;
    height: 16px;
    background-image: url("../images/redo.svg");
    margin: 0 0 0 8px;
}

To hide the button, set the Visible property to false.

Size Modes

Use the SizeMode property to specify a button size. The following code snippet applies different size modes to Button components.

razor

<DxButton Text="Small" SizeMode="SizeMode.Small" />

<DxButton Text="Medium" SizeMode="SizeMode.Medium" />

<DxButton Text="Large" SizeMode="SizeMode.Large" />

For additional information, refer to Size Modes.

Handle the Click Event

Handle the Click event to respond to the button’s click.

razor

<DxButton ...
    Click="@Handler">

@code {
    // ...
    void Handler(MouseEventArgs args) {
        Console.WriteLine("I am clicked!");
    }
}

If you use the NavigateUrl property together with the Click event’s handler, the browser handles the event first and then navigates to the specified URL.

To submit a form with a button click, set the SubmitFormOnClick option to true.

Set the Enabled property to false to disable the button.

razor

<DxButton RenderStyle="ButtonRenderStyle.Primary" Text="Disabled button" Enabled="false" />

Custom Content

You can use the ChildContent property to add custom content to your button and customize its appearance and behavior:

Razor
CSS

razor

<DxButton RenderStyle="ButtonRenderStyle.Info"
              Click="@Like"
              IconCssClass="btn-icon btn-icon-like"
              SizeMode="Params.SizeMode"
              Text="Like">
        @context
        <span class="ms-1">@likes</span>
    </DxButton>
    @* ... *@
@code {
    int likes;

    void Like(MouseEventArgs args) {
        likes++;
    }
    protected override void OnInitialized() {
        likes = 1;
    }
}

css

.btn-icon-like {
    -webkit-mask-repeat: no-repeat;
    mask-repeat: no-repeat;
}
