Expand without selection

[Patrick King]

I'm sure I've simply missed something in the documentation and Demo.  If I have 'rowSelected' event defined on the treegrid, if I click on the expand icon, the rowSelected event is triggered.  Is there a way to not select the row if the expand icon has been clicked?

<ejs-treegrid id="TreeGrid1" dataSource="@ViewBag.datasource1" idMapping="O6CNT" parentIdMapping='O6PRNT' enableCollapseAll="true" treeColumnIndex="0" allowSelection="true" rowSelected="rowselected">
    <e-treegrid-selectionsettings mode="Row"></e-treegrid-selectionsettings>
    <e-treegrid-columns>
        <e-treegrid-column field="O6ORDNUM" headerText="Ord #" textAlign="Right" width="20"></e-treegrid-column>
        <e-treegrid-column field="O6ITEM" headerText="Item#" width="20">></e-treegrid-column>
        <e-treegrid-column field="ODPN" headerText="Part" width="20">></e-treegrid-column>
        <e-treegrid-column field="ODTEXT" headerText="Description" width="60"></e-treegrid-column>
    </e-treegrid-columns>
</ejs-treegrid>

Hi Patrick, 

Thanks for using syncfusion support. 

Query#: Is there a way to not select the row if the expand icon has been clicked? 

 

Yes, We have achieved your requirement by using rowSelecting event. This event gets fired before the rowSelected event, So here we have prevent the selection based on the target. Please refer the below code example for more information. 

<ejs-treegrid id="tree1" rowSelecting="rowselecting" allowPaging="true" dataSource="@ViewBag.datasource" idMapping="TaskId" parentIdMapping="ParentId" treeColumnIndex="0" > 

        <e-treegrid-columns> 

            .  .  .  .  .  .  . 

            .  .  .  .  .  .  . 

        </e-treegrid-columns> 

    </ejs-treegrid> 

 

<script> 

    function rowselecting(args) { 

        if (args.target.classList.contains("e-treegridexpand")) { 

           args.cancel = true;            // It helps to not triggering the rowselected event 

        } 

    } 

    </script>

Thanks so much for the quick response.  This worked perfectly.  I did add e-treegridcollapse to the condition and my rowselected function only processed when not expanding or collapsing the grid.
