Hello


I am trying to show a picture in a Report.

The connection type is JSON, and the picture is a base64 encoded string.

But the picture is not displayed 😕

    Hi you might already found a solution for yourself, but I want to add mine just in case. You can actually Right click on the JSON table then click on new Calculated Column and on the property panel of the new calculated column, set DataType to Byte[], expand the Expression popup editor and type in

    Convert.FromBase64String([JSON.item.Image]) whereas JSON.item.Image is your Base64 string column

Rich Text Editor. To edit a paragraph's style, hit tab to get to the paragraph menu. From there you will be able to pick one style. Nothing defaults to paragraph. An inline formatting menu will show up when you select text. Hit tab to get into that menu. Some elements, such as rich link embeds, images, loading indicators, and error messages may get inserted into the editor. You may navigate to these using the arrow keys inside of the editor and delete them with the delete or backspace key.
