How to Handle grid selection model in accordion layout in collapsed mode.

How to Handle grid selection model in accordion layout in collapsed mode.

Problem:   I have three grid which  are within accordion layout. I have to select the record in gird which is collapsed mode first time view is loaded.

We are getting error as view is not available in  collapse mode.

Solution : we need to handle like below code. Need to add listener to grid to select the grid data after grid expanded first time.

Source Code:

    if (grid.collapsed !== true) {

         grid.getSelectionModel().select(recordArray, true, false);

    } else {

      grid.addListener('expand', function() {

         grid.getSelectionModel().select(recordArray, true, false);

         }, grid, {

             single: true

         });

    }
