DxFlyout.HeaderContentTemplate Property

Specifies a template for content of the flyout window’s header.

Namespace: DevExpress.Blazor

Assembly: DevExpress.Blazor.v23.2.dll

NuGet Package: DevExpress.Blazor

Declaration

[Parameter]
public RenderFragment<IPopupElementInfo> HeaderContentTemplate { get; set; }

Property Value

Type	Description
RenderFragment<IPopupElementInfo>	The header content.

Remarks

Use the HeaderContentTemplate property to display any UI render fragment in the flyout window header’s content area. This template does not affect the default content area rendering (that is, paddings, alignment, etc.)

The HeaderContentTemplate accepts an IPopupElementInfo object as the context parameter. You can use the parameter’s CloseCallback property to implement the Close button.

<DxButton RenderStyle="ButtonRenderStyle.Secondary" Click="() => IsOpen = !IsOpen" Id="flyout-overview-target-container">SHOW A FLYOUT</DxButton>

<DxFlyout @bind-IsOpen=IsOpen
          PositionTarget="#flyout-overview-target-container"
          BodyText="Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor
            incididunt ut labore et dolore magna aliqua. Ut enim ad minim veniam, quis nostrud
            exercitation ullamco laboris nisi ut aliquip ex ea commodo consequat."
          Width="max(25vw, 250px)"
          HeaderVisible="true">
    <HeaderContentTemplate>
        <div class="header-style">
            <DxButton Text="X" Click="@context.CloseCallback" />
        </div>
    </HeaderContentTemplate>
</DxFlyout>

@code {
    bool IsOpen { get; set; } = false;
}
