On event click how to get ChildMember value

[Jeff]

Hi everybody !

I have a radTreeView controller binding by self referencing data from a  programmatically build DataTable..

I define radtreeView ChildMember, ParentMember and DisplayMember properly, all looks fine.

on select event click like mouseclick for instance, I easily can get DisplayMember value using e.Node.Name or e.Node.text,  but I need to get the ChildMember value, and I can't find any way to find It.

 

A piece of help would be great !

Thanks in advance !

Hello, Jeff,   

If you set the RadTreeView.ValueMember property to "id" for example, you can easily extract this value by getting the RadTreeNode.Value property. Thus, in the NodeMouseClick event you have access to the affected node by the RadTreeViewEventArgs.Node property: 

public RadForm1()
{
    InitializeComponent();

    this.radTreeView1.DisplayMember = "name";
    this.radTreeView1.ValueMember = "id";
    this.radTreeView1.ParentMember = "pid";
    this.radTreeView1.ChildMember = "id";
    this.radTreeView1.DataSource = this.GetSampleData();

    this.radTreeView1.NodeMouseClick+=radTreeView1_NodeMouseClick;
}

private void radTreeView1_NodeMouseClick(object sender, Telerik.WinControls.UI.RadTreeViewEventArgs e)
{
    Console.WriteLine(e.Node.Value);
}

I hope this information helps. If you have any additional questions, please let me know.
