Renderer On Date Ranges

CaryRoberts — Wed, 17 Apr 2013 22:29:45 GMT

Hi Everyone,
So lets say I want to symbolize one field that has date and time and break it down by Current_TimeStamp for > 90 days, 60 - 90 days etc. Then I would like to render each selection with a specific color, red, yellow, green. I can select for data range and set the symbols for each range but only the first draws the color. I pull the feature class from SDE and reference the FC three times for each selection, renderer and Geofeaturelayer. The renderer through a loop selects each date and symbolizes each record for each date range (YUK). I figured if I could set individual renderer's for selection I would be OK. Should I continue down this path? Should I try and export the selection to LYR file and import back into ArcMap for symbolization? A bit of confusion here. Heres my code VS 2010 ArcMAP V 10.

            Dim featureInspectLayer As IFeatureLayer = New FeatureLayerClass
            featureInspectLayer.FeatureClass = featureInspectClass
            featureInspectLayer.Name = "Inspections_>_90_Days"
            featureInspectLayer.Visible = True

            ' If activeView Is Nothing OrElse featureInspectLayer Is Nothing OrElse whereClause Is Nothing Then
            'Return
            'End If
            Dim featureInspectSelection As IFeatureSelection = TryCast(featureInspectLayer, IFeatureSelection) ' Dynamic Cast
            ' Set up the query
            Dim feature As ESRI.ArcGIS.Geodatabase.IFeature
            Dim queryFilter As IQueryFilter = New QueryFilterClass '
            Dim Day90Filter As String = "WHERE [InspectionDate] in (SELECT max([InspectionDate]) FROM VECTOR.SDE.PolyInspection GROUP BY [SourceSiteID]) AND InspectionDate <= Current_TimeStamp - 90"

            queryFilter.WhereClause = Day90Filter
            Dim featSelection As IFeatureSelection = featureInspectLayer
            featSelection.SelectFeatures(queryFilter, esriSelectionResultEnum.esriSelectionResultNew, False)
            featSelection.SelectionChanged()

            Dim selectionSet As ISelectionSet = featSelection.SelectionSet
            Dim featCursor As IFeatureCursor = Nothing
            selectionSet.Search(Nothing, True, featCursor)

            Dim NineDay As IRgbColor
            NineDay = New RgbColor
            NineDay.Red = 255
            NineDay.Green = 0
            NineDay.Blue = 0

            Dim symd As New SimpleFillSymbol
            symd.Style = esriSimpleFillStyle.esriSFSSolid
            symd.Outline.Width = 6

            Dim uvRenderer As IUniqueValueRenderer = New UniqueValueRenderer
            uvRenderer.FieldCount = 1
            uvRenderer.Field(0) = "InspectionDate"
            uvRenderer.DefaultSymbol = symd
            uvRenderer.UseDefaultSymbol = True

            Dim sym As ISimpleFillSymbol = Nothing
            feature = featCursor.NextFeature
            Do Until feature Is Nothing
                sym = New SimpleFillSymbol
                sym.Style = esriSimpleFillStyle.esriSFSSolid
                sym.Outline.Width = 6
                sym.Outline.Color = NineDay
                sym.Color = NineDay
                uvRenderer.AddValue(feature.Value(feature.Fields.FindField("InspectionDate")), "", sym)
                feature = featCursor.NextFeature()
            Loop

            ' adds Inspection Feature layer
            activeView.FocusMap.AddLayer(featureInspectLayer)
            activeView.Extent = activeView.FullExtent
            activeView.PartialRefresh(esriViewDrawPhase.esriViewGeography, Nothing, Nothing)
            mapDoc.ActiveView.ContentsChanged()
            featSelection.SelectionChanged()
            pMxDoc.UpdateContents()

            Dim geofeatureInspectLayer As IGeoFeatureLayer = featureInspectLayer
            geofeatureInspectLayer.Renderer = uvRenderer

Thanks Folks

Well Howdy Folks,
I think I was trying to do to much. UVRenderer is for multiple attributes in one field or column, if Im not mistaken. I could get things to renderer but not display. So plan B, everybody has to have a plan b. I decided to query by date range from the most recent entry (date) and export out to file geodatabase and then load back into arc map and then use the simple renderer. Works much better and not much of a load from the query. So heres what I did...
