Example

The following examples control the columns displayed in the ExplorerBrowser.

Copy

explorerBrowser1.Columns.Clear();
explorerBrowser1.Columns.Add(SHCOLUMNID.ShellColumnName);
explorerBrowser1.Columns.Add(SHCOLUMNID.ShellColumnSize);
explorerBrowser1.Columns.Add(SHCOLUMNID.ShellColumnParentFolder);

Copy

//if you want to define the total set of columns at once, this version is much more performant than adding each column seperately.
explorerBrowser1.Columns.SetColumns(new List<SHCOLUMNID>()
{
    SHCOLUMNID.ShellColumnName,
    SHCOLUMNID.ShellColumnSize,
    SHCOLUMNID.ShellColumnElementType
});

Copy

if (IsMyMusic())
{
    //"Show" shows the column at its default position, but you can determine the position by using "Insert" or "Add"
    explorerBrowser1.Columns.Show(SHCOLUMNID.ShellColumnMusicTitlenumber);
    explorerBrowser1.Columns.Show(SHCOLUMNID.ShellColumnSummaryTitle);
    explorerBrowser1.Columns.Show(SHCOLUMNID.ShellColumnMusicArtist);
    explorerBrowser1.Columns.Show(SHCOLUMNID.ShellColumnMusicAlbum);
    explorerBrowser1.Columns.Show(SHCOLUMNID.ShellColumnMusicYear);
    explorerBrowser1.Columns[explorerBrowser1.Columns.Count - 1].Caption = "Custom title";
}

Copy

explorerBrowser1.Columns.Remove(SHCOLUMNID.ShellColumnSize); //Removes the Size column. If it doesn't exist it is skipped.
