File download

This control allows you to represent BLOB data stored in the database as download links. For files stored outside of the database the External File control should be used. If the Setup binary fields as image option is turned ON, the Image control will be automatically selected for all the BLOB columns.

 

 

Use the Additional options to specify templates of file names and content type (optional) to be used for binary files on download and enable the Force downloading option to force browser to download files, instead of open them in the browser.

 

Align

Allows you to specify the alignment of the control. Possible values are Default, Left, Right, and Center.

 

Inline styles

Use this field to set formatting options to be used inside the style attribute of the element. For example, to set the font color and the background color for a control, place the following string to Inline styles:

 

color: red; background-color: yellow;

 

Custom attributes

This property allows you to add simple metadata to individual elements, largely for the purpose of providing information to make JavaScript functions easier. Such attributes can be later handled in client-side events. For example, to add several custom attributes to an editor, enter the following string into the Custom attributes edit box:

 

data-city="Boston" data-lang="js" data-food="Bacon"

 

It is recommended to prefix all custom attributes with data- to keep the result document compatible with the HTML5 requirements.

 

Null label

This property allows you to define how NULL values are represented for this column. By default the value of this property corresponds to the one defined at the project level. You can specify a custom value for a certain column (for example, "Not selected", "Not available" "Not supported", etc.) if necessary.
