Namespace: Kettic.AspNet.Controls
Assembly: Kettic.AspNet.Controls (in Kettic.AspNet.Controls.dll) Version: 2014.4.1129.0 (2014.04.1129.0)

Syntax

C++

Copy

public override Object DataItem { get; set; }

Public Overrides Property DataItem As Object
	Get
	Set

public:
virtual property Object^ DataItem {
	Object^ get () override;
	void set (Object^ value) override;
}

abstract DataItem : Object with get, set
override DataItem : Object with get, set

Property Value

Type: Object
An Object that represents the data item that is bound to the node. The default value is null (Nothing in Visual Basic), which indicates that the node is not bound to any data item. The return value will always be null unless accessed within a NodeDataBound event handler.

Remarks

This property is applicable only during data binding. Use it along with the NodeDataBound event to perform additional mapping of fields from the data item to KaxTreeNode properties.

Examples

The following example demonstrates how to map fields from the data item to KaxTreeNode properties. It assumes the user has subscribed to the NodeDataBound event.

C++

Copy

private void KaxTreeView1_NodeDataBound(object sender, Kettic.AspNet.Controls.KaxTreeNodeEventArgs e)
{
    e.Node.ImageUrl = "image" + (string)DataBinder.Eval(e.Node.DataItem, "ID") + ".gif";
    e.Node.NavigateUrl = (string)DataBinder.Eval(e.Node.DataItem, "URL");
}

Sub KaxTreeView1_NodeDataBound(ByVal sender As Object, ByVal e As Kettic.AspNet.Controls.KaxTreeNodeEventArgs ) Handles KaxTreeView1.NodeDataBound
    e.Node.ImageUrl = "image" & DataBinder.Eval(e.Node.DataItem, "ID") & ".gif"
    e.Node.NavigateUrl = CStr(DataBinder.Eval(e.Node.DataItem, "URL"))
End Sub
