DxAIChatFileUploadSettings.MaxFileSize Property

Specifies the maximum file size in bytes.

Namespace : DevExpress.AIIntegration.Blazor.Chat

Assembly : DevExpress.AIIntegration.Blazor.Chat.v25.2.dll

NuGet Package : DevExpress.AIIntegration.Blazor.Chat

Declaration

csharp

[Parameter]
public int MaxFileSize { get; set; }

Property Value

Type	Description
Int32

The maximum file size in bytes.

Remarks

Set the FileUploadEnabled property to true to enable file upload operations for users.

Once a user attaches a file to a message, the AI Chat component validates the file size. Declare a DxAIChatFileUploadSettings object and specify its MaxFileSize property to limit the maximum size of files that <DxAIChat> can upload. If validation fails, the component cannot upload this file and displays an error message.

Refer to the DxAIChatFileUploadSettings class description for additional information.

Example

The following code snippet activates the file upload functionality in Blazor AI Chat and configures validation rules for uploaded files:

razor

@using DevExpress.AIIntegration.Blazor.Chat

<DxAIChat CssClass="demo-chat"
          FileUploadEnabled="true">
    <AIChatSettings>
        <DxAIChatFileUploadSettings MaxFileCount="2"
                                    MaxFileSize="20000"
                                    AllowedFileExtensions="@(new List<string> { ".jpg", ".pdf" })"
                                    FileTypeFilter="@(new List<string> { "image/*", "application/pdf"})" />
    </AIChatSettings>
</DxAIChat>
