Upload images link

You can insert images by pasting them or using the RadzenHtmlEditorImage tool. By default images are inserted as base64 encoded strings. To upload images to the server you need to implement a file upload endpoint and set the UploadUrl property of the RadzenHtmlEditor component: <RadzenHtmlEditor @bind-Value=@htmlValue UploadUrl="upload/image" />. For a sample implementation check the UploadController.cs tab.
