JLWest:
I have looked at the clean option and not sure if or how you would clean a single column.
Is that possible?

Thanks

There is a public method
--- Code: Pascal [+][-]window.onload = function(){var x1 = document.getElementById("main_content_section"); if (x1) { var x = document.getElementsByClassName("geshi");for (var i = 0; i < x.length; i++) { x[i].style.maxHeight='none'; x[i].style.height = Math.min(x[i].clientHeight+15,306)+'px'; x[i].style.resize = "vertical";}};} ---procedure Clean(StartCol,StartRow,EndCol,EndRow: integer; CleanOptions: TGridZoneSet); overload;which does what you ask for.
The last parameter is normally set to

@howardpc - Where is that documented. I hunted all over for something like this. Probably didn't know the proper syntax for the google search.

Thanks

From the .CHM documentaiton:

--- Code: Text [+][-]window.onload = function(){var x1 = document.getElementById("main_content_section"); if (x1) { var x = document.getElementsByClassName("geshi");for (var i = 0; i < x.length; i++) { x[i].style.maxHeight='none'; x[i].style.height = Math.min(x[i].clientHeight+15,306)+'px'; x[i].style.resize = "vertical";}};} ---TCustomStringGrid.CleanRemoves cell content using the specified options.

The cleaning operation does not change the number of rows and columns on the grid control. It replaces the content for the affected cells with empty strings ('').

At official documentation for the TStringGrid, your specific method you find here.
I hope this helps.
Steps to reproduce using official help ->
1. Open the official TStringGrid documentiation.
2. Search for your method (Clean), you will find out that it is not listed here so go one step above from where TStringGrid comes from
3. You will land at TCustomStringGrid and there you find "Clean" listed.

I hope it helps and sorry that I also answered.
