Autosize columns for TListView

Question

I want to auto-size all the columns in the TListView. I am using below code, but its not doing any thing.

ListView1.Columns.Add.Caption := 'Field Name';
ListView1.Columns.Items[0].Autosize := True;

How can i auto-size the columns of TListView in Delphi.

I set my ViewStyle to vsReport.

Thanks in advance

Answer 1

I got the answer. Setting the column width to -1 or -2 solved the problem.

Use -1 setting to set the column header to the size of the largest subitem text in the column,

and a -2 setting to set the column header to the size of the text in the column header.

ListView1.Columns[0].Width := -1 or -2;
