Hi,
I need to design my Front-end for a Geoprocessing tool with all the input parameters, for which i need to implement IGPFunction.
To get an input Featureclass from the user, my parameter is coded like this.
Dim pParameters As IArray = New ArrayClass()
'Input DataType is GPFeatureLayerType
Dim inputParameter As IGPParameterEdit = New GPParameterClass()
inputParameter.DataType = New GPFeatureLayerTypeClass()
' Default Value object is DEFeatureClass
inputParameter.Value = New GPFeatureLayerClass()
' Set Input Parameter properties
inputParameter.Direction = esriGPParameterDirection.esriGPParameterDirectionInput
inputParameter.DisplayName = "Input Features"
inputParameter.Name = "input_features"
inputParameter.ParameterType = esriGPParameterType.esriGPParameterTypeRequired
pParameters.Add(inputParameter)
This works fine. Now my task is to get a ComboBox, on click of the drop-down menu, i need to get the FieldNames of the input Feature class. (Refer the attached jpeg)
How do i code to get a parameter like this?
Expecting an answer.
