Get the full path

[Kjell]

I use exemple TreeView / Directory Structure.
When I click the button i get the selected file name (default.aspx) with "RadTreeView1.SelectedNode.Text"
How get the full path/address of the selected file, like "/organisation/klubbar/default.aspx"

Hi Kjell,

Following is the sample code that I tried to get the path of the selectednode on an external button click.

ASPX:

<asp:Button ID="Button1" runat="server" OnClientClick="OnClientClick(); return false;"  />

JS:

<script type="text/javascript">
    function OnClientClick() {
        debugger;
        var tree = $find("<%= RadTreeView1.ClientID %>");
        var node = tree.get_selectedNode();
        var s = node.get_text();
        var currentObject = node.get_parent();
        while (currentObject != null) {
            if (currentObject.get_parent() != null) {
                s = currentObject.get_text() + " / " + s;
            }
            currentObject = currentObject.get_parent();
        }
        alert(s);
    }
</script>

Please take a look into this documentation for more information.

Hope this helps.

Princy.

I do not know, but I get only the filename not the full path. Do you have a working example in vb?

Hi Kjell,

Unfortunately I couldn't replicate your issue. Here is the full code that I tried to achieve your scenario.

ASPX:

<telerik:RadTreeView ID="RadTreeView1" runat="server" OnNodeExpand="RadTreeView1_NodeExpand">
</telerik:RadTreeView>
<asp:Button ID="Button1" runat="server" Text="Login" OnClientClick="OnClientClick(); return false;" />

JS:

<script type="text/javascript">
    function OnClientClick() {
        debugger;
        var tree = $find("<%= RadTreeView1.ClientID %>");
        var node = tree.get_selectedNode();
        var s = node.get_text();
        var currentObject = node.get_parent();
        while (currentObject != null) {
            if (currentObject.get_parent() != null) {
                s = currentObject.get_text() + " / " + s;
            }
            currentObject = currentObject.get_parent();
        }
        alert(s);  //s is the path of the selectednode
    }
</script>

VB:

Private ReadOnly KnownExtensions As String() = New String() {"aspx", "asmx", "cs", "vb", "xml", "ascx", _
    "jpg", "png", "gif", "html"}

Private Sub BindTreeToDirectory(virtualPath As String, parentNode As RadTreeNode)
    Dim physicalPath As String = Server.MapPath(virtualPath)
    Dim directories As String() = Directory.GetDirectories(physicalPath)
    For Each directory__1 As String In directories
        Dim node As New RadTreeNode(Path.GetFileName(directory__1))
        node.Value = virtualPath + "/" + Path.GetFileName(directory__1)
        node.ImageUrl = "~/TreeView/Img/Vista/folder.png"
        node.ExpandMode = TreeNodeExpandMode.ServerSideCallBack
        parentNode.Nodes.Add(node)
    Next
    Dim files As String() = Directory.GetFiles(physicalPath)
    For Each file As String In files
        Dim node As New RadTreeNode(Path.GetFileName(file))
        Dim extension As String = Path.GetExtension(file).ToLower().TrimStart("."C)
        If Array.IndexOf(KnownExtensions, extension) > -1 Then
            node.ImageUrl = "~/TreeView/Img/Vista/" + extension + ".png"
        Else
            node.ImageUrl = "~/TreeView/Img/Vista/unknown.png"
        End If
        parentNode.Nodes.Add(node)
    Next
End Sub
Protected Sub Page_Load(sender As Object, e As EventArgs)
    If Not Page.IsPostBack Then
        Dim rootNode As New RadTreeNode("Examples")
        rootNode.Value = "~/TreeView/Examples"
        rootNode.ImageUrl = "~/TreeView/Img/Vista/folder.png"
        rootNode.ExpandMode = TreeNodeExpandMode.ServerSideCallBack
        RadTreeView1.Nodes.Add(rootNode)
    End If
End Sub
Protected Sub RadTreeView1_NodeExpand(sender As Object, e As RadTreeNodeEventArgs)
    BindTreeToDirectory(e.Node.Value, e.Node)
End Sub

Hope this helps.

Sorry I was not clear, I want to save the full path in a database. So I want to pick it out in Code Behind



Protected Sub btnKlick_Click(sender As Object, e As EventArgs) Handles btnKLick.Click

    lblMsg.Text = RadTreeView1.SelectedNode.Text 'get the full path
       save to database..........



End Sub

Hi Kjell,

Try the following code snippet to achieve your scenario.

VB:

Protected Sub Button1_Click1(sender As Object, e As EventArgs)
    Dim node As RadTreeNode = RadTreeView1.SelectedNode
    Dim s As String = node.Text
    Dim currentObject As RadTreeNode = node.ParentNode
    While currentObject IsNot Nothing
        If currentObject.Parent IsNot Nothing Then
            s = currentObject.Text + "/" + s
        End If
        currentObject = currentObject.ParentNode
    End While
    Response.Write(s)
End Sub

Hope this helps.

Regards,
Princy.

thanks, works perfectly.....

One more question, is it possible to set the selected node ("/organisation/klubbar/default.aspx") by default in Page Load

I have save the full path in a database.

    If Not Page.IsPostBack Then......
        expanded and selected, for example "/organisation/klubbar/default.aspx"

Hello Kjell,

You can refer to this Code Library where similar behavior have been explained. 

Hope this will be helpful.
