Edit Sheet and Renumber/Revise Ladder through C#

[mcoH3VZV]

In my typical autocad template drawing, the sheet number is 101 with two columns 00-39 for lines 10100 through 10139.  I want to be able to programmatically change the sheet and revise the ladder. I was able to search and find the WD_M block and change the sheet attribute. However, this does not revise the ladder. Is there a simple ACAD API function that renumbers the ladder, or is there a better way of doing this as a whole via a program?

Thanks,

The answer is to search and find the WD_M block first and edit only that block. Change the Sheet attribute to whatever it needs to be.  Then, run this command:

doc.SendStringToExecute("(command (c:wd_ladr_reref)) ", true, false, false);

This will re-number the ladder based on the sheet you changed it to.
