Hi,
I try to select rows in a treegrid control but I'm a bit confused..

Is there a simple way to select a treegrid row from its ID ?

Thanks !

Hi Julien,

To achieve your requirement, we have get the row index value for a particular record in a TreeGrid and select it with the help of its primary key value. This can be achieved by passing the required primary key value to the getRowIndexByPrimaryKey method from Grid instance which that returns the index value of the row. With the help of this row index value the particular record can be selected by using the selectRow method.

Refer to the code below:-

App.Component.html:-

 

<button ej-button (click)="selectRow()">selectRow</button>

  <ejs-treegrid

    #treegrid

    [dataSource]="data"

    childMapping="subtasks"

    height="550"

    [treeColumnIndex]="1"

  >

    .    .     .

   </e-columns>

 

</ejs-treegrid>

 

App.Component.ts:-

 

selectRow() {

        var index = this.treegrid.grid.getRowIndexByPrimaryKey(9);

        // Select the row using the index value

        this.treegrid.selectRow(index);

    }
