In a StringGrid without(!) defined columns you never see that up and down arrow in the TitleButton if you click to sort this column.

It's ok if you define at least one column, but i think that shouldn't be this way.

Attached patch comments out

//FImageIndex := -1;

My first patch :-)

I don't get what is exact problem. If there's no columns why Sort indicator should be visible at all (and where) ?
In any case you can create bug report and attach example project.

Hi Zeljko,

think of a *.csv file and StringGrid.LoadFromCSV...

No columns defined in StringGrid, they will be created "on the fly" and user wants to sort a column by click on columnTitle.

There are default arrows that only show up if you define at least one column and thats not ok i think!
