Hello,

I have been looking into your question and prepared a small sample in order to test the described behavior.

However, since version 9 is considered retired and no longer eligible for Developer Support Services, the provided sample is using the latest version i.e. 16.0.0 and there could be differences in the properties and methods between these versions. Having this in mind, my suggestion is to update to the latest version.

Anyways, what I could say is that on my side everything works as expected and I'm able to get the row data, however, please note that getRowByIndex() accepts as parameter row index i.e. value between 0 and (data.length - 1). If your requirement is to get a specific row by primary key what I could suggest is using the getRowByKey() method.

Regarding your second question about getting the column data, an approach I could suggest is to get the required column via getColumnByVisibleIndex(index: number) or getColumnByName(field: string) and loop through its cells collection in order to get each cell value:

    //Get column via getColumnByVisibleIndex() or getColumnByName()
    this.grid1.getColumnByVisibleIndex(0).cells.forEach((cell) => {
      console.log(cell.value);
    });
