   ByVal val As LabelValue _
) 
Visual Basic (Usage)Copy Code
Dim instance As LabelValueCollection
Dim val As LabelValue
 
instance.Remove(val)
C# 
public void Remove( 
   LabelValue val
)

Parameters

val
The LabelValue to be removed.

Example

The following example removes the smallest cities from a renderer via the ValueMapLabelRenderer's collection. It first drills down into the layer (which has a GroupRenderer) to find the LabelValueCollection. Then it iterates through the values, finding the value range based on the minimum value. If found, the value is removed from the renderer.
Visual BasicCopy Code
' Access the values collection of a value map label renderer
Dim layer As FeatureLayer = mapView.Layers.FindByName("Cities")
Dim grpRend As GroupRenderer = layer.Renderer
Dim valueMapLabelRend As ValueMapLabelRenderer = grpRend.Renderers(0)
Dim valueColl As LabelValueCollection = valueMapLabelRend.Values
 
Dim valueToRemove As LabelValue = Nothing
 
'Find the value range to remove
For Each value As LabelValueRange In valueColl
    If value.MinValue = "-99" Then
        valueToRemove = value
        Exit For
    End If
Next
 
' If found, remove the value range
If Not IsNothing(valueToRemove) Then
    valueColl.Remove(valueToRemove)
End If
C#Copy Code
// Access the values collection of a value map label renderer
FeatureLayer layer  = mapView.Layers.FindByName("Cities");
GroupRenderer grpRend = layer.Renderer;
ValueMapLabelRenderer valueMapLabelRend  = grpRend.Renderers(0);
LabelValueCollection valueColl = valueMapLabelRend.Values;
 
LabelValue valueToRemove = null;
 
// Find the value range to remove
foreach (LabelValueRange value in valueColl)
{
    if (value.MinValue == "-99") {
        valueToRemove = value;
        break;
    }
}
 
// If found, remove the value range
if (valueToRemove != null)
    valueColl.Remove(valueToRemove);

Remarks

The input parameter must be a valid reference to an existing Value object in the collection, either a LabelValueRange or a UniqueLabelValue object.
