    Hi Team,
    After integrating with the latest Wijmo build(), I see that the column headers displayed in my grid is not the text provided to the header attribute but it is displaying the text from the binding attribute. I have attached a screenshot of the same.

    grid = new wijmo.grid.FlexGrid(hostElem, {
    autoGenerateColumns: false,
    columns: [
    { binding: 'VALIDATION_MESSAGE', header: 'Validation', width: COL_WIDTH_100, isReadOnly: true }

    It is supposed to display "Validation" in this case.

    Please let me know if there's any change with the flexgrid properties.

    Hi Keertana,

    We are sorry but we are unable to replicate the issue at our end. Could you please have a look at the following sample and let us know if we are missing something in order to replicate the issue:

    Also, from the shared snapshot, it seems like FlexSheet control instead of the FlexGrid, please let us know if the issue is with the FlexSheet control instead.

    Hi Sharad,
    We are adding a bound sheet to the flexSheet, passing the flexGrid . Pls check the snippet below.

    sheet= new wijmo.grid.sheet.FlexSheet(id);
    sheet.addBoundSheet('New sheet',sheet_data, 0, grid);

    Hi Sharad,
    Thanks for acknowledging.
    Is there a work around to fix this?
    And when is your next release planned for?

    We could use the formatItem event as a workaround.
    Please refer to the following code snippet:
    if(e.panel.cellType != wijmo.grid.CellType.Cell){
    let row = e.panel.rows[e.row];
    if(row instanceof wijmo.grid.sheet.HeaderRow){
    let grid = s.selectedSheet.grid;
    e.cell.innerText = grid.columns[e.col].header;

    You may also refer to the following sample demonstrating the same: https://stackblitz.com/edit/js-ekj6c8?file=index.js

    The next stable release is planned for March end. If everything goes well, it would be published in the 2nd - 3rd week of March. :)

    even ------- flexSheet.evaluate("2+2") is not working. Our all calculation throughout the application is not working.
