Hello rchiu5hk,

I have been looking into this forum thread and you could do the steps below in order to achieve what you are looking for:

1. In order to export just the Date part you should set the CellFormat in your Worksheet to the desired one, in a CellExported event like:

        private void ultraGridExcelExporter1_CellExported(object sender, Infragistics.Win.UltraWinGrid.ExcelExport.CellExportedEventArgs e)
        {
            if (e.GridColumn.Key == "Your dateTime column key")
                e.CurrentWorksheet.Rows[e.CurrentRowIndex].Cells[e.CurrentColumnIndex].CellFormat.FormatString = "mm/dd/yyyy";
        }

 2. In order to remove the RowSelectors from your UltraGrid, you could use the InitializeLayout event of the UltraGrid to do so like:

        private void ultraGrid1_InitializeLayout(object sender, Infragistics.Win.UltraWinGrid.InitializeLayoutEventArgs e)
        {
            e.Layout.Override.RowSelectors = Infragistics.Win.DefaultableBoolean.False;
        }

Please feel free to let us know if you have any other questions with this matter
