[Help]Treeview Search Button[Solved]

How to I make a search button with a textbox for a TreeView?

Ex: I write "Age Of Empires" in the textbox and when I click SEARCH, i want that it selects the root or the child that has Age of Empires in the named.

Thanks

First add this function to your form:

Code:

Private Sub FindNodes(ByVal n As TreeNode)
        Dim x As TreeNode
        For Each x In n.Nodes
            If x.Text = Me.TextBox1.Text Then
                x.BackColor = Color.Indigo
                x.Parent.ExpandAll()
            End If
            FindNodes(x)
        Next
    End Sub

Then double click textbox1 and add the following code to it (Textbox_TextChanged Event):

Code:

Dim nodes As TreeNodeCollection = TreeView2.Nodes
        Dim n As TreeNode
        For Each n In nodes
            FindNodes(n)
        Next

Will expand and highlight all roots and children containing the specified words !!

It doesnt work , when i click search , nothing happens?

*EDIT* it works but only when i type a cd key.
ex: i want that when i type Age of Mythology and I click search, it selects the text because now it only select the child (cd-key) and not the root (games)

OK Got It. Here's the final edited code:

Code:

Private Sub FindNodes(ByVal n As TreeNode)
        Dim x As TreeNode
        For Each x In n.Nodes
            x.BackColor = Color.White
        Next
        For Each x In n.Nodes
            If UCase(x.Text) = UCase(Me.TextBox1.Text) Then
                x.BackColor = Color.LightGray
                x.Parent.BackColor = Color.LightGray
                x.Parent.ExpandAll()
            End If
            FindNodes(x)
        Next
    End Sub
    Private Sub TextBox1_TextChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles TextBox1.TextChanged
        Dim nodes As TreeNodeCollection = TreeView2.Nodes
        Dim x As TreeNode
        For Each x In nodes
            x.BackColor = Color.White
        Next
        Dim n As TreeNode
        For Each n In nodes
            If UCase(n.Text) = UCase(TextBox1.Text) Then
                n.BackColor = Color.LightGray
            End If
            FindNodes(n)
        Next
    End Sub

Tested and working. Enjoy
