Hello,

I am using auto-size on a column in a datawindow and that works well. My problem is when the text wraps around, I want to know either the height of the column or the number of lines it now has. I tried using describe to get the height and I tried using linecount() to get the number of lines but neither works. Describing the Height doesn't give the height after wrapping and linecount() returns -1

What is the trick?

 

Thank you,

Steven Watkins

Hi, Steven - 

Miguel is correct. The RowHeight() DataWindow expression function will return the height of a row that contains one or more auto-size height columns in the units used by the DataWindow data object.

Attached is an example external-source DW that contains its own data and uses Pixels as the unit of measure.

Best regards, John

Maybe you can set the detail band to be auto-size-height.

Then use the RowHeight() function?

 

Maybe this will help out too: https://community.appeon.com/index.php/qna/q-a/how-to-determine-new-height-of-a-column-with-autosize-height-true
