does the c# example here http://demos.telerik.com/aspnet/prometheus/TreeView/Examples/Functionality/MultipleSelect/DefaultCS.aspx look correct?

I am trying to write the multiply selected tree nodes to a label - It seemed the node_click event would be what i need - however I've seen others have had some issues with it and apparently i am not going down the right path.

I don't see how to set the radtreeview control to autopostback = true

here is what i attempted

using

System;

using

System.Data;

using

System.Configuration;

using

System.Collections;

using

System.Web;

using

System.Web.Security;

using

System.Web.UI;

using

System.Web.UI.WebControls;

using

System.Web.UI.WebControls.WebParts;

using

System.Web.UI.HtmlControls;

using

System.Data.SqlClient;

using

Telerik.Web.UI;

public

partial class radman : System.Web.UI.Page

{

protected void Page_Load(object sender, EventArgs e)

{

RadTreeView1.DataSource = createOrgTreeTable();

RadTreeView1.DataFieldID =

"OrgId";

RadTreeView1.DataFieldParentID =

"OrgParent";

RadTreeView1.DataTextField =

"Name";

RadTreeView1.DataValueField =

"Name";

RadTreeView1.MultipleSelect =

true;

RadTreeView1.DataBind();

}

private DataTable createOrgTreeTable()

{

SqlConnection sqlConn = new SqlConnection(TPWConfiguration.DbConnectionString);

sqlConn.Open();

SqlCommand CmdRoot = new SqlCommand("tpw_direct_reports_listing_all", sqlConn);

CmdRoot.CommandType =

CommandType.StoredProcedure;

CmdRoot.Parameters.Add(

new SqlParameter("@UserId", SqlDbType.VarChar));

CmdRoot.Parameters[

"@UserID"].Value = "jjb000;

DataTable dtOrgTree = new DataTable();

dtOrgTree.Columns.Add(

"OrgId");

dtOrgTree.Columns.Add(

"OrgParent");

dtOrgTree.Columns.Add(

"login");

dtOrgTree.Columns.Add(

"name");

SqlDataAdapter daRoot = new SqlDataAdapter(CmdRoot);

daRoot.Fill(dtOrgTree);

return dtOrgTree;

}

protected void ShowSelected()

{

lblSelectedNodes.Text =

"";

foreach (RadTreeNode node in RadTreeView1.SelectedNodes)

{

lblSelectedNodes.Text +=

"<br/>" + node.FullPath;

}

}

protected void Button1_Click(object sender, EventArgs e)

{

ShowSelected();

}

}

Hi Jeff,

Please modify the code in your Page_Load method like this:

if (!IsPostBack)  
{  
    RadTreeView1.DataSource = createOrgTreeTable();  
    RadTreeView1.DataFieldID = "OrgId";  
    RadTreeView1.DataFieldParentID = "OrgParent";  
    RadTreeView1.DataTextField = "Name";  
    RadTreeView1.DataValueField = "Name";  
    RadTreeView1.MultipleSelect = true;  
    RadTreeView1.DataBind();  

because now RadTreeView is created on every postback and loses its selection.

ok that worked - except i don't want the full path - yet the underlying datavalue field of the clicked node. How would i get those values?  The example shows fullpath - i need childpath but i don't see such a property.

Hello Jeff,

You can simply use node.Text or node.Value.
