Question

how can I sort the destination list when transferring based on the “Text” so it will look something like

A
B
C

Now it seems like the transfer button causes a postback, but i am not sure where to add it and how to sort it since it is being binded in a method like this (the destination listbox)

protected void BindDestinationCollection()
{
    StoreItems storeItems =new StoreItems();

    DataSet dsStoreItems= storeItems.GetDestinationItemsByID(ItemID);
    DataView view = new DataView();

    if (dsStoreItems.Tables[0] != null && dsStoreItems.Tables[0].Rows.Count > 0)
    {
        lstDestinationListBox.Items.Clear();
        view = dsStoreItems.Tables[0].DefaultView;
        view.Sort = "ItemName ASC";
        lstDestinationListBox.DataSource = view;

         lstDestinationListBox.DataTextField = "ItemName";
         lstDestinationListBox.DataValueField = "ItemID";
         lstDestinationListBox.DataBind();
     }  
}

Answer 1

After transferring the items, in the OnTransferred event handler, use the following code:

//sorts items by text
RadListBox1.Sort();
