Error when adding items about imagelistview HOT 3 CLOSED

Did you create the custom column before calling your LoadItem method? e.g:

ImageListView1.Columns.Add(ColumnType.Custom, "My Group Column")

Otherwise can you please post the stack trace?

Thanks,

Hi,
Thanks for your help.
Yes, I had added the custom column and in fact it seems that this is what is 
causing the problem. If I call SetSubItemText on a column that is a custom type 
it throws an index out of range error. If the column type is set to something 
else I seem to get no errors.
It is easy to replicate the error - Create a form, add an ImageListView object. 
Add the following to the form's onload event:
        Me.ImageListView1.Columns.Add(Manina.Windows.Forms.ColumnType.Custom, "My Column")
        Me.ImageListView1.Items.Add("C:\Users\Quentin\Dropbox\My Pictures\200512221836_00039.jpg")
        Me.ImageListView1.Items(0).SetSubItemText(0, "Blah")
When it is run an error occurs on and Items.Add method with the following stack 
trace:

    at System.String.InternalSubStringWithChecks(Int32 startIndex, Int32 length, Boolean fAlwaysCopy)
   at System.String.Substring(Int32 startIndex, Int32 length)
   at Manina.Windows.Forms.Utility.GroupTextAlpha(String text)
   at Manina.Windows.Forms.ImageListViewItem.UpdateGroup(ImageListViewColumnHeader column)
   at Manina.Windows.Forms.ImageListView.ImageListViewItemCollection.Sort()
   at Manina.Windows.Forms.ImageListView.ImageListViewItemCollection.AddRemoveGroupItem(Int32 index, Boolean add)
   at Manina.Windows.Forms.ImageListView.ImageListViewItemCollection.InsertInternal(Int32 index, ImageListViewItem item, ImageListViewItemAdaptor adaptor)
   at Manina.Windows.Forms.ImageListView.ImageListViewItemCollection.AddInternal(ImageListViewItem item, ImageListViewItemAdaptor adaptor)
   at Manina.Windows.Forms.ImageListView.ImageListViewItemCollection.Add(ImageListViewItem item, ImageListViewItemAdaptor adaptor)
   at Manina.Windows.Forms.ImageListView.ImageListViewItemCollection.Add(ImageListViewItem item)
   at Manina.Windows.Forms.ImageListView.ImageListViewItemCollection.Add(String filename, Image initialThumbnail)
   at Manina.Windows.Forms.ImageListView.ImageListViewItemCollection.Add(String filename)
   at WindowsApplication1.Form1.Form1_Load(Object sender, EventArgs e) in C:\Users\Quentin\AppData\Local\Temporary Projects\WindowsApplication1\Form1.vb:line 4
