zoomToSelectedExtent or dataDrivenPages.refresh()

ChadFoster — Mon, 17 Dec 2012 21:25:25 GMT

pre 10.1, I had a script that would zoom to selected features. at 10.1 that same script crashed when it came to zoomToSelectedFeatures(). Is this something that is going to become usable again? If not, is there a workaround?

The script uses a MXD that has Data Driven Pages enabled, I have also been trying to get dataDrivenPages.refresh() to work, but I keep getting errors.

Has anyone experienced either of these situations?

Thanks

DF.zoomToSelected() works fine at 10.1. There must be something specific to your code. The same applies to .refresh(). It would be much more helpful if you provided a snippet of your code along with the error messages.

In nutshell, the script is used in an MXD with Data Driven Pages. I can see the progression of the script on screen while running. The select statement below is working, but the zoomToSelectedFeatures() does not work and there is no error message.

At the end of the script when I try the data driven pages refresh, I encounter this error message:
Traceback (most recent call last):

df = arcpy.mapping.ListDataFrames (mxd, "Layers")[0]
arcpy.SelectLayerByAttribute_management(layer, "NEW_SELECTION", selstring)
df.zoomToSelectedFeatures()
mxd.dataDrivenPages.refresh()

The "layer" in the select statement is from arc.getParameterAsText(0) with data type in properties parameters set to Layer.

The "layer" in the select statement is from arc.getParameterAsText(0) with data type in properties parameters set to Layer.

Try this:
Set the layer name parameter as a string type. Enter a string value that is equal to the layer name in the TOC.

Then try:

lyrName = arcpy.getParameterAsText(0)
mxd = arcpy.mapping.MapDocument (r"T:\1_DOUGLAS_PROJECTS\......\_SINGLE_PARCEL.mxd")
df = arcpy.mapping.ListDataFrames (mxd, "Layers")[0]
lyr = arcpy.mapping.ListLayers(mxd, lyrName, df)[0]
arcpy.SelectLayerByAttribute_management(lyr, "NEW_SELECTION", selstring)

Jeff,

I made the corrections as you suggested, the script still functions, however the

df.zoomToSelectedFeatures()

does not do anything and the

mxd.dataDrivenPages.refresh()

still throws an error message.

Traceback (most recent call last):
File "T:\1_DOUGLAS_PROJECTS\B_RESEARCH_AND_DEVELOPMENT\3_PROGRAMMING_AND_SCRIPTING\PYTHON\DC_NOTICING_SINGLE.py", line 200, in <module>

Can you send a map package and your script to jbarrette@esri.com. I'll take a look.

If you can't send me a map package, at least send my your script so I can look at it.

Hi Chad. I was going through this exact script and wanted to have it refresh data driven pages. Coincidentally, I stumbled on this post.

This worked:

ddp = mxd.dataDrivenPages #creates the object
ddp.refrech()‍‍‍‍

(he worked where I work now and I am updating his script)
