In this sample http://asp.syncfusion.com/demos/web/treegrid/columntemplate.aspx, how to show the icons to expand/collapse the nodes?

Hi Jorge,

We can render the Expand/ Collapse icons as like in the normal TreeGrid samples by removing all the styles in the sample and include “e-icon” this class with the e-treegridexpand and e-treegridcollapse. Please refer the below code example for details.

<script type="text/x-jsrender" id="customColumnTemplate">     

      <div class='{{if expanded}}e-treegridexpand e-icon  {{else hasChildRecords}}e-  

           treegridcollapse e-icon {{/if}}' style='height:20px;width:30px;margin:auto;float:left;margin-left:10px;'




We have also prepared a sample based on this and you can find the sample under the following location.
