Before Client click in new Version of Rad Treeview

[Rahul Khinvasara]

Hi,
In my application I have replaced controls with this new version of  Asp.net for ajax.
There is one RadTreeview on whose BeforeClientClick i had written one script but after changing it to new version, this script is not working.
Below is the code:

<

telerik:RadTreeView ID="tvDetractionTypes" runat="server" DataTextField="Title" DataFieldID="ID"

BeforeClientClick="handleNodeClick" DataValueField="ID" DataFieldParentID="ParentDetractionTypeID"

Skin="Office2007" DataSourceID="dsDetractionTypes" Height="150px" Width="250px"

OnNodeBound="tvDetractionTypes_NodeBound">

</telerik:RadTreeView>

<

script type="text/javascript">

function

handleNodeClick(node)

{

//if this is a parent node, expand it and select the first child

if (node.Parent == null && node.Nodes.length > 0)

{

node.Expand();

node.TreeView.UnSelectAllNodes();

node.Nodes[0].Select();

return false;

}

// Unlock any locked sliders

SliderArrays[0][idxSliderLocked] =

false;

SliderArrays[1][idxSliderLocked] =

false;

SliderArrays[2][idxSliderLocked] =

false;

SliderArrays[3][idxSliderLocked] =

false;

// Make sliders visible

SliderArrays[0][idxSliderDisplay] =

true;

SliderArrays[1][idxSliderDisplay] =

true;

SliderArrays[2][idxSliderDisplay] =

true;

SliderArrays[3][idxSliderDisplay] =

true;

// Redraw the sliders to reflect the new default values

SliderArrays[0][idxSliderDisplayWeight] = node.Attributes[

"DefaultTech"];

SliderArrays[1][idxSliderDisplayWeight] = node.Attributes[

"DefaultEquip"];

SliderArrays[2][idxSliderDisplayWeight] = node.Attributes[

"DefaultPatient"];

SliderArrays[3][idxSliderDisplayWeight] = node.Attributes[

"DefaultProcess"];

SliderDrawTable();

// Change the default DV

// Change the tooltip text

return true;

}

</script>

Can anyone tell which event should be used now..?
and how to get node and its attributes in my above script.
I tried using OnClientClicking but not succeed.
Plese help.
Thanks.

Hi Rahul,

Please take a look at this link to get information on the client-side events and properties available to you with the RadTreeView control.

For your specific problem, you can use the OnClientNodeClicking event. I have created a simple example to demonstrate how to use this event to access the node that caused it:

	<telerik:RadCodeBlock ID="RadCodeBlock1" runat="server">
	<script type="text/javascript">
	function handleNodeClick(sender, eventArgs) {
	var node = eventArgs.get_node();
	// put the rest of your code here...
	}
	</script>
	</telerik:RadCodeBlock>
	<telerik:RadTreeView ID="RadTreeView1" runat="server"
	OnClientNodeClicking="handleNodeClick">
	<Nodes>
	<!-- Insert nodes here, or you can add them
	from a datasource or programatically    -->
	</Nodes>
	</telerik:RadTreeView>

I hope this was helpful. Please let me know if you continue to have problems.

Regards,
Kevin Babcock

Hello Rahul Khinvasara,

Please check this help page which describes in detail the changes between the "classic" and ajax treeview. You should now use the OnClientNodeClicking event instead.
