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 LVSCW_AUTOSIZE or LVSCW_AUTOSIZE_USEHEADER solved the problem.

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

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

uses CommCtrl;

ListView1.Columns[0].Width := LVSCW_AUTOSIZE or LVSCW_AUTOSIZE_USEHEADER;

Of course, it's better to use the appropriate constants: ColumnHeaderWidth = LVSCW_AUTOSIZE_USEHEADER; or ColumnTextWidth = LVSCW_AUTOSIZE;. – Parous

Just wanted to add that this doesn't work if you set the width from the Object Inspector. – Altruistic

Unfortunately, this overrides the MinWidth property. It should be vice versa. – Eolith

should this size be set after every time I add an item or just once? – Jibheaded

I've updated the answer to use the constants. – Sherard

I think you just need LVSCW_AUTOSIZE_USEHEADER. That will auto-size the column to fit the largest of the header or the items. Or-ing the two constants doesn't appear to work. – Sherard

Answer 2

Just set columns width to -1

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

Try this:

// Assign vsReport;    
ListView1.ViewStyle := vsReport; 

  { // Add your items  }

// Assign vsList again;
ListView1.ViewStyle := vsList;
