Multiple Selection
Configuring Multiple Selection
The Combobox can be configured to allow multiple selection.
Check the Enable Multi-Select box under Basic Settings :
Send Value on Select All
By default, the Combo Box widget will send the Keyword “All” in the parameter without differentiating every element if all elements are selected.
But in the case of passing parameter to a Stored Procedure or Displaying them in a label, It could be more revelant to list all items instead of keyword “All”
If the checkbox Send Values on Select All is checked, it will work as suggested and all elements will be listed in the parameter.
Selecting items at runtime
A checkbox appears in front of every item, allowing multiple selection :
In addition, a new selection item called “Select All” (or “Unselect All”) is added at the top, to allow to select/unselect all items at once.
