  Hi,

  I need to find the object type whether it is Row or Column. Here is my sample code (in TypeScript).

  public myMethod(panel: wijmo.grid.GridPanel, r: number, c: number, cell: HTMLElement): void {
  
  let className: any;
  
  if (panel.columns[c].binding === “Value”) {
  
  className = this.getClassName(panel.rows[r]);
  
  } else {
  
  className = this.getClassName(panel.columns[c]);
  
  }
  
  // code continues here
  
  …
  
  }

  Here is the code in getClassName function:

  private getClassName(value: any): boolean {
      let columnName: any;
      let fieldDetails: FieldDetails;
      [b]if (value.GetType() === wijmo.grid.Row) {[/b]
          columnName = this.flexGrid.columns[1].header;
          fieldDetails = value._data.row.FieldDetails;
      [b]}else if (value.GetType() === wijmo.grid.Column) {[/b]
          columnName = value._hdr;
          fieldDetails = this.fields.find(field => field._aliasName === columnName);
      }
      // code continues here
      ...............
  

  }

  In my above getClassName, the value.GetType() in if and else if throws error as undefined.

  How to find the value type whether the passed object is Row / Column type ?

  Appreciate your ideas/suggestions.

  Thank you.

  HI,

  Inorder To check whether the object passed is an instance of a row or column, I suggest you should use instanceof operator instead of getType:

  private getClassName(value: any): boolean {
  let columnName: any;
  let fieldDetails: FieldDetails;
  if (value instanceof wijmo.grid.Row) {
  columnName = this.flexGrid.columns[1].header;
  fieldDetails = value._data.row.FieldDetails;
  }else if (value instanceof wijmo.grid.Column) {
  columnName = value._hdr;
  fieldDetails = this.fields.find(field => field._aliasName === columnName);
  }
  // code continues here
  ...............
  }
