Lookup control common properties

This article describes common properties of the Lookup control, which you can edit in the designer, but also shows how the same properties can be used dynamically with JavaScript.

General

Name

A unique identifier for the control.

Control's name

JavaScript

The Name property allows to work with the control via JavaScript code, like this:

fd.spRendered(function(){
    //can access the control using its Name:
    fd.control('Control1').ready(function(control) {
       // alert selected option as a text string
       alert(control.value.Title);
    });
 });

Layout

Define whether the Title will appear to the left of the control or directly above it:

Layout property

Orientation can also be changed directly in the context menu of the selected control:

Edit layout property

Required

Select if the control will be required to submit the form or not.

Control's required status

JavaScript

This code will allow you to get and set control’s required status

//returns the control's required status as true/false
fd.control('Control1').required;

//sets the control's required status
fd.control('Control1').required = true;

Hint

Defines a placeholder text that appears in the input before a user starts typing:

Hint property

JavaScript

This code will allow you to get or set the control’s placeholder text dynamically:

//sets the control's Hint
fd.control('Control1').placeholder = "Enter your name";

Read-only

Define whether a user can view or edit the contents of the control:

Read-only property

Class

Add a CSS class to the control, which comes in handy with CSS or even JavaScript code. This will work like class attribute for an HTML tag.

Control's class

Same class can be applied to multiple controls, and then you can use CSS to modify the appearance of these controls. For example, here we’ve used the following CSS code in CSS editor to give controls with my-class a blue background, white text and rounded corners, with a little bit of padding:

.my-class {
    color: #FFFFFF;
    padding: 10px;
    background-color: #1E90FF;
    border-radius: 30px;
}

Style

Add custom CSS style to the control. This will work like style attribute for an HTML tag.

Control's style

This style will allow you to hide the control, making it invisible to user (but still usable with JavaScript):

display: none;

You can also apply different styles to it. For example, the following style will allow you to add a thin gray border around the control:

padding: 10px;
border: 1px solid #CED4DA;

Title

Here you can find properties specifically related to the control’s title.

Width

Specify in pixels how much space should the control’s title take.
