Get currentViewData Indexes

Question

Is there a way to get the indexes for Grid.CurrentViewData, so I can set them selected e.g.?

Hi Sebastian,Greetings from Syncfusion support.We checked your query, based on that we suspect your requirement is to select the rows based on currentViewData values. For this, we suggest you to pass the currentViewData primaryKey value to the Grid’s getRowIndexByPrimaryKey method to get that row index and then pass the row index to the Grid’s selectRows method to the select those rows in the Grid as demonstrated in the below code example.Code Example: 




 let genarateData: Button = new Button({}, '#select'); 
genarateData.element.onclick = () => { 
  var data = grid.currentViewData; 
  var rowIndex = []; 
  data.forEach((d) => { 
    if (d['Title'] == 'Sales Representative') { 
      var index = grid.getRowIndexByPrimaryKey(d['EmployeeID']); 
      rowIndex.push(index); 
    } 
  }); 
  grid.selectRows(rowIndex); 
}; 
 
let grid: Grid = new Grid({ 
  dataSource: employeeData, 
  allowSelection: true, 
  selectionSettings: { type: 'Multiple' }, 
  enableHover: false, 
  columns: [ 
    { 
      field: 'EmployeeID', 
      headerText: 'Employee ID', 
      textAlign: 'Right', 
      width: 135, 
      isPrimaryKey: true, 
    }, 
    { field: 'FirstName', headerText: 'Name', width: 125 }, 
    { field: 'Title', headerText: 'Title', width: 180 }, 
    { 
      field: 'HireDate', 
      headerText: 'Hire Date', 
      textAlign: 'Right', 
      width: 135, 
      format: { skeleton: 'yMd', type: 'date' }, 
    }, 
  ], 
}); 
grid.appendTo('#Grid');
