Hello Kumar,

Thank you for posting in our community.

What I can suggest for achieving your requirement is using formatter option of igGrid columns. This is a reference to a function which will be used for formatting cell values. This function has two arguments, val - that holds current cell value and record - that holds the whole record values. My idea is to create a formatter function for Amount column where you will calculate the value based on the "Percentage" column value. When editing if you update the Percentage column`s value formatter function will reflect that in the Amount column`s value. For example:

column.For(x => x.fltAmount).HeaderText("Amount").FormatterFunction("formatVal"); //Amount

//define formatVal function

<script>

function formatVals(val, record) {

var formattedVal = record.Percentage * predefined value;

return formattedVal;

}

</script>

Keep in mind that formatting operates at grid rendering phase and does not affect the data in the underlying data source. Some further reference about formatting can be found here.

Please test this approach on your side and let me know if it helps you achieve your requirement.

My suggestion is to handle igNumericEditor`s valueChanged event. In this event the value of the other depended editor can be set according to your formula. For example:

1) Define the valueChanged event in Updating column settings collection:

  .Features(f =>
            {
                f.Updating()
                    .EnableAddRow(false)
                    .EditMode(GridEditMode.Row)
                    .ColumnSettings(cs =>
                    {
                        cs.ColumnSetting().ColumnKey("Id").ReadOnly(true);
                        cs.ColumnSetting().ColumnKey("Amount").NumericEditorOptions(opts=> {
                            opts.AddClientEvent("valueChanged", "amountValChanged");
                        });
                        cs.ColumnSetting().ColumnKey("Percentage").NumericEditorOptions(opts =>
                        {
                            opts.AddClientEvent("valueChanged", "percentageValChanged");
                        });
                    });
            })

2) Handle valued in valueChanged event hadnlers:

    <script>
        $(function () {
            window.amountValChanged = function(evt, ui) {
                $("#grid").igGridUpdating("editorForKey", "Percentage").igNumericEditor("value", ui.newValue * 2);
            }
            window.percentageValChanged = function (evt, ui) {
                $("#grid").igGridUpdating("editorForKey", "Amount").igNumericEditor("value", ui.newValue / 2);
            }
        });
    </script>

Please test this suggestion on your side and let me know if you have any additional questions afterwards.

What I can suggest for having the vice versa dependency of these cells is handling editCellEnding event of the Updating feature. In this event you can check which is the cell that triggered it and if it as any of the Amount or Perecntage cells to update the other one accordingly using setCellValue method. For example:

$(document).delegate("#grid", "iggridupdatingeditcellending", function (evt, ui) {
                if (ui.columnKey === "Amount") {
                    var value = ui.value * 2; //make your calculcations here
                    $("#grid").igGridUpdating("setCellValue", ui.rowID, "Percentage", value);

                }
                if (ui.columnKey === "Percentage") {
                    var value = ui.value / 2; //make your own calculations here
                    $("#grid").igGridUpdating("setCellValue", ui.rowID, "Amount", value);
                }
            });

Please keep in mind that this approach will work as expected for editMode set to "cell". If you have a requirement for "row" editMode please let me know.
