Radio Button

When you have fewer items to display, you can use the Radio Button control instead of the Dropdown control. Make sure that you have unique items bound to the control.

You can use arrays to populate the options of a Radio Button control.

General

• List Source - The source for the items to be displayed in the multi select dropdown. Valid data types include arrays of String or Integer, DateTime, DataTable, or arrays of an Object.
• Column - When the list source is either of type DataTable or an array of an Object, select the specific column(for DataTable data types) or the specific property (for Object arrays).
• Hint Text - The help text to be displayed at runtime.
• Default Selected Value- The default values to be displayed at runtime.
• Tooltip - The text to be displayed when an app user hovers over the control. Use this to provide additional information on the control.
• Label - The display text of the control.
• Required - If true, app users must provide data in the control. To mark the control as mandatory at runtime, an asterisk * is added after the label text.

• Custom error message - The text to be displayed if the Required property is set to true and the control is left empty.

• Hidden- If true, hides the control at runtime.

• Disabled - If true, disables the control at runtime.

Events

• Value changed - Configure what happens when the radio button value is changed.

Style

• Control Alignment - By default, inherits the parent alignment. A different alignment other than the parent can be set. To default back to the parent alignment, deselect the overridden options.

  Note: The alignment is dependent on the layout selected for the parent (Vertical vs Horizontal).
• Label Placement - By default, the label is set to be displayed on top of the control, at the left side. You can place it to the left of the control, on the same line. The Label Width property configures how wide the label should be, and the Space between property sets the distance between the label and the control.
• Layout - The layout of radio button options (vertical or horizontal). By default, it is set to horizontal. The Allow wrapping property to wraps the radio buttons to multiple lines, and the Space between property sets the distance between the radio buttons options.
• Color - The color of the radio button when it is selected.
• Background color - The background color of the control.

• Font - The font attributes for both the label and the input text, such as font family, size, color, or style (Bold, Italic and Underline). By default, the control inherits the font family of the immediate parent container which is indicated by the keyword "Inherited".

• Margin - The margin of the control. By default, a margin of 4px is set. Top/Bottom and Left/Right margin properties are combined. These properties can be detached using the Link button at the right side of the Margin section.
• Size - The width and height of the control. By default, the size is set to auto. To set minimum or maximum values, click the three dot icon (...). If the size of the control is smaller than the options, a scroll bar is displayed.
