Summary: VFP9SP2 - combobox (List Type) in SCX form not showing proper
DisplayValue for negative values
Controlsource is thisform.oRecord.ireftype, which is an integer field.
The cbo is built on the fly when the form shows depending on the record
data in thisform.SetReference method shown here:
LOCAL loBox as ComboBox, lcTransType as String
loBox = this.cboReference
lcTransType = this.oRecord.cTransType
loBox.Clear
*** mjb 03/29/2012 - changed SHIP and BUY to use NEGATIVE values for
iRefType
DO CASE
<snipped>
CASE lcTransType = "BUY"
loBox.AddItem("Supplier")
loBox.AddListItem("-6",loBox.NewItemId,2)
*loBox.Enabled = .T.
loBox.Value = -6 && Supplier
* after assigning the value above to -6, it still doesn't show
"Supplier" and the DisplayValue is still "" until I force it on the next
line
loBox.DisplayValue = "Supplier"
* at this point, the displayvalue truly is Supplier since I set
it
above, but after the next line's refresh, it goes back to nothing ("")
loBox.Refresh()
<snipped>
ENDCASE
I'm investigating this, but wanted to throw this out to the forum to see
if anyone's had a problem using NEGATIVE integer values in the
dropdowns. Other traits of this cbo:
- RowSourceType is 0 (None)
- ColumnCount = 2
- ColumnWidths = "150,0"
- BoundColumn = 2
- BoundTo = .T.
My alternate plan to test next is instead of using negative values to
use some waaaay high never-reached-value like 6000.
