Run Demo: AI Chat – File Attachments

To activate file upload:

1. Enable the FileUploadEnabled property to allow users to attach files.
2. Use the OptionsFileUpload property to configure additional settings based on your project requirements, such as the maximum file size, allowed file types and extensions, and the maximum number of files users can attach to a message.

C#

aiChatControl1.FileUploadEnabled = DevExpress.Utils.DefaultBoolean.True;
aiChatControl1.OptionsFileUpload.FileTypeFilter.AddRange(new List<string> { "text/plain", "application/pdf", "image/png" }); // Allowed MIME types.
aiChatControl1.OptionsFileUpload.AllowedFileExtensions.AddRange(new List<string> { ".txt", ".pdf", ".png" });
aiChatControl1.OptionsFileUpload.MaxFileCount = 5;
aiChatControl1.OptionsFileUpload.MaxFileSize = 5 * 1024 * 1024; // 5 MB

VB.NET

aiChatControl1.FileUploadEnabled = DevExpress.Utils.DefaultBoolean.True
' Allowed MIME types.
aiChatControl1.OptionsFileUpload.FileTypeFilter.AddRange(New List(Of String) From {"text/plain", "application/pdf", "image/png"})
aiChatControl1.OptionsFileUpload.AllowedFileExtensions.AddRange(New List(Of String) From {".txt", ".pdf", ".png"})
aiChatControl1.OptionsFileUpload.MaxFileCount = 5
aiChatControl1.OptionsFileUpload.MaxFileSize = 5 * 1024 * 1024 ' 5 MB
