Finishing up the ImportBooks code

Let's have a look at the rest of the code in the ImportBooks form. The form load just populates the storage spaces list, if any existing storage spaces have been previously saved:

private void ImportBooks_Load(object sender, EventArgs e) 
{ 
    PopulateStorageSpacesList(); 
                         
    if (dlVirtualStorageSpaces.Items.Count == 0) 
    { 
        dlVirtualStorageSpaces.Items.Add("<create new storage         space>"); 
    } 
 
    lblEbookCount.Text = ""; 
} 

We now need to add the logic for changing the selected storage space. The SelectedIndexChanged() event of the dlVirtualStorageSpaces control is modified as follows:

private void dlVirtualStorageSpaces_SelectedIndexChanged(object sender, EventArgs e) 
{ 
    int selectedValue =  dlVirtualStorageSpaces.SelectedValue.ToString().ToInt(); ...
