Hiding a ColumnHeader...

[Alan Seunarayan]

Hello,
I have a number of ColumnHeaders that are 'hidden' (width
set to zero). However, it is still possible to size
them. The reason why they are hidden is to give the
illusion that they do not exist. Is there a way to stop
the user from being able to resize column headers that I
have set their width to zero?

Many thanks,

Alan

The only way to make the cols disappear completely is to make the
underlying data columns invisible. If I'm not mistaken, there's a
"visible" property on a DAtaCOlumn object.
Set this to false and your problem is solved.

Sorry,
I am actually using a ListView control.

Hmm. IN that case I don't think there's a way

Well there is a way and it is quite simple.

The columns are stored in the ListView.Column s collection, so you can remove
and add columns as you like.
Only those in the collection will be shown.

E.g.
System.Windows. Forms.ColumnHea der headerToShowHid e = new
System.Windows. Forms.ColumnHea der();

private void ToggleColumn()
{
if (this.myListVie w.Columns.Conta ins(headerToSho wHide))
{
this.myListView .Columns.Remove (headerToShowHi de);
headerToShowHid e.Text = "Now I am hidden";
}
else
{
headerToShowHid e.Text = "See me now?";
this.myListView .Columns.Insert (1, headerToShowHid e);
}
}

Just remove it when you want to hide it.
Insert it at the desired position and you see it again.
