Example

The following code snippet applies different size modes to ComboBox components.

<DxComboBox Data="@Cities" NullText="Select City ..." @bind-Value="@Value" SizeMode="SizeMode.Small" />
<DxComboBox Data="@Cities" NullText="Select City ..." @bind-Value="@Value" SizeMode="SizeMode.Medium" />
<DxComboBox Data="@Cities" NullText="Select City ..." @bind-Value="@Value" SizeMode="SizeMode.Large" />

@code {
    IEnumerable<string> Cities = new List<string>() {
        "London",
        "Berlin",
        "Paris",
    };
    string Value { get; set; }
}

Global Size Mode Property

Use the SizeMode application-wide option to specify the size mode for DevExpress Blazor components that support size modes. Individual component settings override this option.

You can specify a size mode in the Blazor Project Wizard.

The wizard adds the SizeMode global option in the Program.cs file.

Program.cs

builder.Services.AddDevExpressBlazor(options => {
    options.SizeMode = DevExpress.Blazor.SizeMode.Small;
});
