List Controls

In this section we'll discuss how to use List Controls.

• Create a UIController called "DemoComboBox"
• Add a local NumberColumn called "OurDataInCombo"
• Place a ComboBox on the View, and bind it's data to the local column "OurDataInCombo"
• We can set the values of the Combo Box, by changing the Values propery in the property sheet
  
  or in the control's quick properties
  
• If no values are set in the ComboBox's Values property - the attached column's InputRange values will be used as Values

public readonly NumberColumn OurDataInCombo = new NumberColumn
{
    InputRange = "4,5,6"
}; 

• Values that are set in the control's Values property override the values that were set to the Column's InputRange property
• When we want the ComboBox to display values that are different from it's underlying value (descriptions for a code etc... we can use the DisplayValues property
• For example, if we set the Values properties to "1,2,3" and the DisplayValues property to "Noam, Yoni, Eran".
  • When the user selects Noam, the data bound column will have the value of 1.
  • When the user selects Yoni, the data bound column will have the value of 2.
  • When the user selects Eran, the data bound column will have the value of 3.

• Binding List Control Values to an Expression
• Binding List Control Values to Data from the Database
