RadDropDownListItem Properties

For each RadDropDownListItem,

  • Text is the string that the user sees for the item in the drop-down list.

  • Value is the value associated with the item. It determines the value of the dropdownlist's SelectedValue property when the item is selected.

  • ToolTip is a string that appears in the tooltip window when the user hovers the mouse over the item in the drop-down list.

Setting the tooltip can enable an accessibility feature: Special accessibility readers like JAWS can pronounce the tooltip of the highlighted item.

  • Selected lets you control which item is initially selected when the RadDropDownList first appears.

Only one item can be selected at a time. If you set Selected to True for an item, the Selected property of all other items is automatically set to False .

  • Enabled determines whether the user can select the item from the drop-down list.

  • CssClass is the name of a CSS style to be applied to the dropdownlist item. The style can be declared in the CSS file of the applied skin.
