DataGrid - Access both column and component instances in setCellValue in Angular

created 7 years ago

Hi team,

I tried firing setcellvalue callback on cell value change.at the same time I need to change the value of another column for this I need to have row data.To access row data  I tried setting global variable value in roweditstart event with batch edit mode.The strange thing I am facing is row data won't be available in setvalue callback.I am using DX datagrid html5,type script and angular. Please suggest what could be the problem and what could be the solution. Your help much appreciated.

Kind regards

Hi,

Updated

As I understand, you wish to access a component instance and also keep the callback function execution context? If so, you can use the apply method to complete this task:

TypeScript
constructor(service: Service) {
  ...
  origOnSetCellValue = this.setCellValue;
  this.setCellValue = function() {
      origOnSetCellValue.apply(this, [].slice.call(arguments, 0, 3).concat([that]));
  };
}
setCellValue(rowData, value, currentData, componentInstance){
    console.log(componentInstance);
    rowData[(<any>this).dataField] = value;
    rowData.FirstName = "foo";
}

Please check this example demonstrating this scenario.
