Web resource properties for model-driven app forms

You can add or edit web resources on a form to make it more appealing or useful to app users. Form enabled web resources are images or HTML files controls.


Silverlight web resources are deprecated and will not work in the Unified Interface client.

  • When adding a web resource:: Select the tab (for example, General or Notes) you would like to insert it on, and then on the Insert tab, select Web Resource.
    Insert Web resource
  • When editing a web resource: Select a form tab and the web resource that you want to edit, and then on the Home tab, select Change Properties.

Web resource properties

The Add Web Resource or Web Resource Properties dialog box will have two, sometimes three tabs depending on the type of web resource.

These properties define the web resource to use and how it should behave.

Column Description
Web resource Required. Look up an existing web resource or create a new one. Use the Form Enabled Web Resource view to include only HTML and image web resources that can be added as visual elements in a form.

Depending on the type of web resource you select, set additional properties.

For HTML web resources you will see these:

For Image web resources you have the option to specify Alternative Text that is important for assistive technologies that make the page accessible to everyone.

Formatting tab

On the Formatting tab, the options that display vary based on the type of web resource inserted and the context where it is inserted. These options include specifying the number of columns and rows display, whether a border displays, and the scrolling behavior.

Dependencies tab

A web resource may interact with columns in the form using script. If a column is removed from the form the script in the web resource may break. Add any columns referenced by scripts in the web resource to the Dependent columns so that they cannot be removed accidentally.

Pass parameters to web resources

An HTML web resource can accept parameters to be passed as query string parameters.

Information about the row can be passed by enabling the Pass row object-type code and unique identifiers as parameters option. If information is typed into the Custom Parameter(data) column it will be passed using the data parameter. The values passed are:

Parameter Description
data This parameter is only passed when text is provided for Custom Parameter(data).
orglcid The Organization default language LCID.
orgname The name of the organization.
userlcid The user’s preferred language LCID
type Don't use this. The table type code. This numeric value can be different for custom tables in different organizations. Use table type name instead.
typename The table type name.
id The id value of the row. This parameter has no value until the table row is saved.

Any other parameters are not allowed and the web resource will not open if other parameters are used. If you need to pass multiple values, the data parameter can be overloaded to include more parameters within it.

More information: Developer Documentation: Pass contextual information about the row
