VB:
This is code that is part of the setup and used to test find routine:
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Dim item As CrumbBarItem
Dim childItem As CrumbBarItem
item = New CrumbBarItem()
item.Name = "item1"
item.Text = "Item 1"
CrumbBar1.Items.Add(item)
childItem = New CrumbBarItem()
childItem.Name = "item2"
childItem.Text = "Child Item 1"
item.SubItems.Add(childItem)
childItem = New CrumbBarItem()
childItem.Name = "item3"
childItem.Text = "Child Item 2"
item.SubItems.Add(childItem)
Console.WriteLine(FindCrumbBarItem(CrumbBar1, "item1"))
Console.WriteLine(FindCrumbBarItem(CrumbBar1, "item2"))
Console.WriteLine(FindCrumbBarItem(CrumbBar1, "item3"))
End Sub
This is code that performs actual lookup:
Private Function FindCrumbBarItem(ByVal subitems As IList, ByVal name As String) As CrumbBarItem
For Each item As CrumbBarItem In subitems
If item.Name = Name Then
Return item
End If
Dim childItem As CrumbBarItem = FindCrumbBarItem(item.SubItems, name)
If Not childItem Is Nothing Then Return childItem
Next
Return Nothing
End Function
Private Function FindCrumbBarItem(ByVal crumbBar As CrumbBar, byval name as String) As CrumbBarItem
Return FindCrumbBarItem(crumbBar.Items, name)
End Function
