HI all,
I inherited a .NET class extension that provides a form so our techs can add/modify features and/or attributes. I had to add several fields to an existing layer which have to go on the form as a combo box. These new fields get populated based on the values that get returned from an overlay function. The overlay function is returning the domain code value instead of the code, so its returning the value "Aqua Hedionda Tributary" instead of the code "AHT". When the next function tries to populate the field with "Aqua Hedionda Tributary" it gets ignored as if it doesn't recognize the value, even though the dropdown list is populated with all of the code values from the field's domain.
These functions already exist, I'm just adding additional fields and layers for overlay and to be populated via the form.
Can anyone tell me what the issue is?
- Why in the overlay function do some features return the code and some features return the value?
- Why can't I pass the domain value to populate the comboBox.selectedValue.
Here's the code....
This call the overlay function
obj.Value(obj.Fields.FindField(Globals.SoCalWetlandType)) = Globals.overlayFC(obj, overlaySoCalWetland, "WetType")
This is the overlay function
Public Function overlayFC(ByRef obj As IObject, ByRef layerName As String, ByRef fieldname As String) As String
Dim pWorkspace As IWorkspace
Dim pObjectClass As IObjectClass
Dim pdataset As IDataset
Dim pFC As IFeatureClass
Dim pFeatCursor As IFeatureCursor
Dim pFeat As IFeature
Dim result As String = Nothing
Dim i As Int32 = 0
pObjectClass = obj.Class
pdataset = CType(pObjectClass, IDataset)
pWorkspace = pdataset.Workspace
pFC = OpenFC(pWorkspace, layerName)
Dim pSP As ISpatialFilter
pSP = New SpatialFilter
pSP.Geometry = CType(obj.Value(obj.Fields.FindField("Shape")), IGeometry5)
pSP.SpatialRel = esriSpatialRelEnum.esriSpatialRelIntersects
pSP.GeometryField = pFC.ShapeFieldName
pFeatCursor = pFC.Search(pSP, True)
pFeat = pFeatCursor.NextFeature()
Do Until pFeat Is Nothing
'If i > 0 Then result = result + ", "
result = result + pFeat.Value(pFeat.Fields.FindField(fieldname)).ToString
'i = i + 1
pFeat = pFeatCursor.NextFeature()
Loop
Return result
FunctionThis is the form where the cbo boxes get populated with the domains and where the values from the overlay function get passed as the selected value.
Public Property frmTarget() As IObject
'This property is a reference to the feature being created or edited. When the feature is selected then
'this property gets updated by the parent class extension. When this happens the data entry fields are updated
'by this section
Get
Return _object
End Get
Set(ByVal value As ESRI.ArcGIS.Geodatabase.IObject)
_object = value
If Not _object Is Nothing Then
If Not m_bCombosFilled Then
'********************************
'Dim RecName = "AHCT"
'Dim SoCalType = "FLUV"
'***********************************************

m_dctDomainValueHolder = Globals.getDomainArray(_object, Globals.SoCalWetlandType)
m_bsSoCalWetlandType.DataSource = m_dctDomainValueHolder
With cboSoCalWetlandType
.DisplayMember = "Key"
.ValueMember = "Value"
.DataSource = m_bsSoCalWetlandType
End With
'cboReceiveWaterBuffer.SelectedIndex = -1
'cboSoCalWetlandType.SelectedValue = SoCalType
cboSoCalWetlandType.SelectedValue = _object.Value(_object.Fields.FindField(Globals.SoCalWetlandType)).ToString
End if
End If
End Set
End Property
