DxPopup.HeaderTemplate Property

Specifies the template used to display the entire header.

Namespace: DevExpress.Blazor

Assembly: DevExpress.Blazor.v21.1.dll


public RenderFragment<IPopupElementInfo> HeaderTemplate { get; set; }

Property Value

Type Description

The template.


Use the HeaderTemplate property to customize the entire header. Predefined appearance settings do not apply. In the template, you can display any UI fragment (formatted text, images, another component, and so on). The template accepts an IPopupElementInfo object as the context parameter. You can use the parameter’s CloseCallback property to implement the Close button.

Implement two-way binding for the Visible property to show the Popup in code and update the property value when a user closes the Popup.

<div @onclick="@(() => PopupVisible = true)">

<DxPopup @bind-Visible="@PopupVisible"
         BodyText="Lorem ipsum dolor sit amet, consectetur adipiscing elit. Mauris sit amet metus vel
             nisi blandit tincidunt vel efficitur purus. Nunc nec turpis tempus, accumsan orci auctor,
             imperdiet mauris. Fusce id purus magna."
        <div style="background-color:rgb(95,54,141); color:white; padding-left:10px; font-size:20px">
        <DxButton RenderStyle="ButtonRenderStyle.Primary" Text="OK"
                  Click="@context.CloseCallback" />

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

Run Demo: Popup - Customization

You can also use the following properties to customize the header:

  • HeaderText - Allows you display plain text and applies all predefined appearance settings.
  • HeaderContentTemplate - Allows you to customize the header’s content area and applies predefined content alignment and paddings.

The HeaderTemplate property takes priority over the HeaderText and HeaderContentTemplate properties.
