Hi

I have set the columreorder to true

Is there a way to get/set the current columnorder, so i can restore the
order from a saved setting ?

Hi Johan,

The following should work similar to your needs. By storing arrays of
ColumnHeaders, you're actually getting references to the same ColumnHeader
objects that are currently in your ListView. Thus beware, if something in
the ColumnHeader object changes (say, the Text), then it'll change for all
the arrays that you capture. The only specific part of getting and
settings these arrays are that they capture the ordering of the particular
columns. If you wish to capture the exact state, then you'll need to copy
the ColumnHeader objects too.

Notice, for the SetColumnOrder() method, BeginUpdate() and EndUpdate() are
called to ensure that clearing the columns and adding the columns get
updated all at once for the end user, instead of the user being able to
"see" the intermediate zero-column state.

Do you have any further questions?

using System.Windows.Forms;
using ColumnHeaderCollection =
System.Windows.Forms.ListView.ColumnHeaderCollection;
...
public ColumnHeader[] GetColumnOrder(ListView lView) {
ColumnHeaderCollection columns = lView.Columns;
int count = columns.Count;
ColumnHeader[] arr = new ColumnHeader[count];
for(int i = 0; i < count; i++) {
arr = columns;
}
return arr;
}

public void SetColumnOrder(ListView lView, ColumnHeader[] arr) {
ColumnHeaderCollection columns = lView.Columns;
lView.BeginUpdate();
columns.Clear();
columns.AddRange(arr);
lView.EndUpdate();
}
...

Hope this helps,
