Hi there! I have an mxd with dataDrivenPages already enable but with some values that I want to change, first with a loop I search for a layer named "River" on the mxd, then I want to change what's on the first screen of the DDP window: Index Layer, Layer and Name Field, but so far I haven't been able to do it, I have the next code and I don't get any error messages but nothing really happens.My Data Frame name is "Carto" and I want to set as Index Layer the layer "River" also that layer has a field named "key" wich is the one that I want to set as Name Field.mxd = arcpy.mapping.MapDocument(r"D:\MyFile.mxd") df = arcpy.mapping.ListDataFrames(mxd)[0] for lyr in arcpy.mapping.ListLayers(mxd, "Carto", df): if lyr.name == "River": mxd.dataDrivenPages.pageRow = "River" mxd.dataDrivenPages.pageRow.nameField = "key" mxd.dataDrivenPages.refresh() mxd.save()
Any Idea?...Thanks! 🙂
