How is each row content in the DataGridView added？

[ringchenhao]

I stepped through the code and generally understand the process, but specifically regarding how rows are displayed in the DataGridView after the LoadingFinished , I still don't fully grasp it. it seems that when i step after "dataGridView.Enabled = true",and the contents are being showed on the dataGridView.
Could you please explain it and show how does this work? Thank you

private void LoadingFinished()
{
    _logger.Info("File loading complete.");

    StatusLineText("");
    _logFileReader.FileSizeChanged += OnFileSizeChanged;
    _isLoading = false;
    _shouldCancel = false;
    dataGridView.SuspendLayout();
    dataGridView.RowCount = _logFileReader.LineCount;
    dataGridView.CurrentCellChanged += OnDataGridViewCurrentCellChanged;
    dataGridView.Enabled = true;
    dataGridView.AutoResizeColumns(DataGridViewAutoSizeColumnsMode.DisplayedCells);
    dataGridView.ResumeLayout();
    _progressEventArgs.Visible = false;
    _progressEventArgs.Value = _progressEventArgs.MaxValue;
    SendProgressBarUpdate();

Go through LoadFile in LogWindowsPublic.cs and then work your way through it, and it will be clear

you mean OnDataGridView_CellPainting ?

Yes: public void CellPainting(DataGridView gridView, int rowIndex, DataGridViewCellPaintingEventArgs e)

Paints the current logline.

Its implemented that way, because its to slow if you add the file as datasource to the datagrid, also the datagrid does not support files that are updated every 10 ms etc.
