Description
The class uses a checkbox column bound to an array property to keep selections, so a logical/numeric column in source alias is not needed. Selected keys (specified in .keyColumn) and first column values are kept in aSelKeys and .aSelDispValues array properties. After the selection, the TooltipText will contain a .cDelimiter delimited list and .cSelectedKeys a comma delimited list of keys. Simple quote is replaced with .quoteEscapeSeq Its usage is intended for small lists, usually to generate IN() clauses for SQL selects. Properties that affect behavior : .showHeaders = .T./.F. specifies if list has column headers .columnHeaders : Custom headers for columns, delimited by "," .captionAllSelected : display values if all items selected .captionPartialSelected : display value if partial selection .captionNoneSelected : display value for no item selected .captionCmdAll : select all button caption .captionCmdNone : clear selections button caption

Great Class, easy to use. I have noted that If the Style Property is changed to 1-DropdownList the properties captionAllSelected and captionNoneSelected are not showed when one is selected. Antonio Carlos Kleinubing, November 21, 2007

I must be missing something. To bad there isn't any documentation. When I try to run the test form, I get "record number 5, property out of bounds". When I try to open cboms, I get a similar message "property value out of bounds". MS should have gave us a multi-select combobox! Chuck Williams, January 7, 2008

These errors are because new _memberdata property introduced in VFP9. If you use VFP8, you can clear _memberdata by opening .scx as table and edit Properties memo column Dorin Vasilescu, January 7, 2008

Nice class. I have one question about it. If I know what selections are made prior to showing the dropdown list, how do I get those records selected/highlighted and have the tooltiptext showing the correct text? Mike Sue-Ping, April 29, 2008
