This is very much needed!

Or also looking for ability to capture the normal 'left click' event with the specific cell.

Hi,

will this feature be implemented? It is highly needed.

Temporary workaround:

use OnRowContextMenu and JS interop to get column index, or event column field.

async Task OnRowContextMenu(GridRowClickEventArgs args)
{
  var mouseEventArgs = args.EventArgs as MouseEventArgs;
  await ContextMenuRef.ShowAsync(mouseEventArgs.ClientX, mouseEventArgs.ClientY);
  var colIndex = await _js.InvokeAsync<int>("app.getColIndex", mouseEventArgs);
  // alternative
  var field = await _js.InvokeAsync<int>("app.getColField", mouseEventArgs);
}

and javascript

class App {

    getCell() {
        return document.elementsFromPoint(clientX, clientY).find(e => e.matches('[role="gridcell"]'));
    }

    getColIndex({ clientX, clientY }) {
        let cell = document.elementsFromPoint(clientX, clientY).find(e => e.matches('[role="gridcell"]'));
        if (!cell) {
            return -1;
        }
        return Number.parseInt(cell.getAttribute('data-col-index'));
    }

    getCellField({ clientX, clientY }) {
        let cellIndex = getColIndex({ clientX, clientY });
        var grid = document.elementsFromPoint(clientX, clientY).find(e => e.matches('[role]="grid'));
        var header = grid.querySelector(`[role]="columnheader"[data-col-index]="${cellIndex}"`);
        return header.getAttribute('data-col-field');
    }
}

window.app = new App();
