Treeview Doubleclick on Node

[Reto Ruemmeli]

Hi

I am trying to execute a dblclick event on a treenode.

For this I used the Nodeclicked event and want to catch the number of clicks with args.event.tapCount.

This works on the nodeExpanding event but not here.

Is there a way to get the dblclick event on the node.

Thanks for the help

<ejs-treeview id="treedata" animation="anim" cssClass="custom" expandOn="None" nodeClicked="nodeClick" nodeExpanding="nodeExpanding" EnablePersistence="true">
<e-treeview-fields id="CategoryID" datasource="TreeDataSource" parentId="ParentID" text="Name" hasChildren="hasChild" expanded="true"></e-treeview-fields>
</ejs-treeview>


<script>
function nodeClick(args) {
var treeObj = document.getElementById('treedata').ej2_instances[0];
var targetNodeId = treeObj.selectedNodes[0];

// Does not work
if(args.event.tapCount==2 ){
// do something
}
}


function nodeExpanding(args) {
// Works
if(args.event.tapCount==2 ){
args.cancel=true;
}
}

</script>

Hi Reto,

Greetings from Syncfusion support.

We have validated your requirement in the TreeView component. Currently, we have not provided support to get the tap count in the NodeClicked event of TreeView. To achieve your requirement, we suggest you bind the double click event for the TreeView component as shown in the below code snippet.

[index.cshtml]

document.addEventListener('DOMContentLoaded', function () {

  document.getElementById("treeData").addEventListener("dblclick", function ()

  {

      console.log("onDoubleClick is trigerred");

  });

});

You can find the sample from below link.

Hi Leo

I have tested it also in combination with a Contexmenu and the nodeClick event. Everything worked.

Thanks a lot

kind regards, Reto
