Why Not Accept TreeView SelectedNode based onTextBox.Text ?

[Nicomendox]

wtihs this code I set Focus to TreeView Node.

 Private Sub Button12_Click(sender As Object, e As EventArgs) Handles Button12.Click
        
        'Expand(TextBox3.Text) '("C:\7143\Baltek")
        gotNode = False
        For Each n As TreeNode In Me.TreeView1.Nodes
            If Not gotNode Then
                
                selectTreeNode(n, TextBox3.Text) ' "C:\7143\Baltek")

                
            End If
          
        Next

    End Sub

When I try to set focus TreeViewNode based on TextBox.Text (with dont care uppercase, lowercase) then no result.

For Excample Node Tag is "C:\7143\Baltek")

if I enter "C:\7143\baltek") or "C:\7143\BalteK") no result, because of Upper LowerCase typing

how can I adjust to find not with any type textbox.text.

Presumably you are performing a String comparison in that 'selectTreeNode' method so you need to make that comparison case-insensitive. You don't need us to tell you how to do that because you can find out in a matter of seconds by searching the web with the appropriate keywords, e.g. "vb.net case insensitive comparison".

thanks for edvice but I couldnt find a solution. but same problem here

Private Sub Button13_Click(sender As Object, e As EventArgs) Handles Button13.Click
        For Each n As TreeNode In Me.TreeView1.Nodes(0).Nodes
            If n.Text = "Users" Then
                TreeView1.SelectedNode = n
                TreeView1.Select()
                TreeView1.SelectedNode.Expand()

            End If
        Next
    End Sub

When Type "Users" 'With Capital "U"

TreeView.SelectedNode is Focus On "C:\Users"

But When I type "users" with "u"

this time result is nothing.

is the problem about TreeView or about the Code ?

As implied earlier, it is about the code:

            If n.Text = "Users" Then

That is a case sensitive comparison (ie: only "Users" will match, "users" or "USERS" etc wont), and you want a case insensitive comparison.

Following the advice about a web search (using the text jmcilhinney provided) gives many relevant results, including this one:
