Hi

I have created a new layer using MakeXYEventLayer_management using python scripting. I want to make this newly created layer time enabled pragmatically. Is there any way to do it. thanks in advance

Hi Nadeem,

You'll need another layer that already has it's time properties set as desired (set manually in ArcMap). Then when you create a layer, you can update its time properties using the other layer as a source using arcpy.mapping.UpdateLayerTime(). It should only update the time properties.

Good Luck!

Hi Kerry
Thnx for the help. also is it also possible to enable the "enable time on this layer" property of a layer through python programming.I mean rather than doing it manually in ARCMAP, i wish to do it through python script.
Regards

The "isTimeEnabled" property is actually a property of the "LayerTime" property, and "LayerTime" is a property of the layers you're working with. Both of those properties are Read Only, so you can't edit them *directly* with Python code. Fortunately, layer time properties can be "updated" in Python (using the UpdateLayerTime function that I mentioned in my last post). As long as you enable the time on the layer file that you're using as a "time properties template," then any layer that you update with it will be time enabled. I don't know why Esri won't let us change the "isTimeEnabled" property directly.

thanks kerry. I want to ask one more thing . It is about the "Time slider" control . I have used it from the toolbar. I have manually set its property and it plays temporal data in my layer. However I want to make a python script that automatically activate the Time slider control I mean user does not need to click the Time slider rather the python script should show it. Additionaly i also wish to stop and play the control using the python script. I know there is a DataFrameTime object that could be used to change the properties of Time slider but I am not sure how to actually use it to play, stop and pause the Time slider control .
Thank you in advance
