How To Deselect Row In Ag-Grid Without Unselecting Other Rows In Angular

Introduction

I have Ag-Grid and on page load. It shows all the rows selected.

Now, I am going to show how to deselect single or multiple rows one by one.

Explanation

Now, in this image, I have selected All Rows on Page Load and I want to deselect the rows one by one and then select rows one by one.

Now, you can see that in the second picture, I deselect Single without deslecting other rows.

Code For This

   $scope.gridOptions = {
        columnDefs:

   { headerName: "CompanyName", field: "CompanyName", editable: true, width: 130 },
  { headerName: 'ProductName', field: "ProductName", editable: true, width: 130 },
   { headerName: "ProjectID", field: "ProjectID", editable: true, width: 100 },
   { headerName: "Status", field: "Status", editable: true, width: 100 },
{ headerName: "Delete", field: "Delete", editable: true, editable: false, width: 100 cellRenderer: customEditorImageWQ },
    { headerName: "Update", field: "Update", editable: true, editable: false, width: 100, cellRenderer: customEditor }],
        rowData: null,
        enableColResize: true,
        enableSorting: true,
        rowSelection: 'multiple',
        angularCompileRows: true,
        rowDeselection: true,
        onRowClicked: RowClick,
        enableFilter: true,
        editable: true,
        suppressRowClickSelection: true,
    };


    function RowClick(param) {
        var currentRowIndex = param.rowIndex;
        $scope.temp = 0;
        $scope.gridOptions.api.forEachNode(function select(node, idx) {
            if (idx == currentRowIndex && $scope.temp == 0) {
                var success = false;
                var data = $scope.gridOptions.api.getSelectedRows();
                for (var iRows = 0; iRows < data.length; iRows++) {
                    if (data[iRows]["CompanyName"] == param.data.CompanyName) {
                        success = true;
                        break;
                    }
                }

                if (success == false) {
                    $scope.gridOptions.api.selectNode(node, true, true);
                    $scope.temp++;


                }
                else {
                    $scope.gridOptions.api.deselectNode(node);
                    $scope.temp++;

                }
            }
        });
    }
