Public Sub SetEmptyMessageAreaTemplate(
    template As RenderFragment
)

Parameters

Name	Type	Description
template	RenderFragment	The empty message area template.

Remarks

You can modify the text or template displayed in the message area when a chat has yet to start.

Use one of the following members:

• EmptyStateText - Specifies the empty area message.
• SetEmptyMessageAreaTemplate - Specifies a template (RenderFragment) that customizes the empty area.

Note

If you specify both the EmptyStateText property and this template, the chat control uses the template and ignores the EmptyStateText property.

Example

The following example customizes the empty message area:

aiChatControl1.SetEmptyMessageAreaTemplate(builder => {
    builder.OpenComponent<EmptyArea>(0);
    builder.CloseComponent();
});

The EmptyArea.razor file:

<style>
    .demo-chat-ui-description {
        font-weight: bold;
        font-size: 20px;
        text-align: center;
    }
</style>

<div class="demo-chat-ui-description">
    AI Assistant is ready to answer your questions.
</div>
