Hi Miki,
Sorry for the delay in responding.
GridTextAlign is used to align the text when image and text is present in the cell. GridHorizontalAlignment is used for horizontal alignment of contents in the cell. Hence in order to make the text in the cell start from left, you can set HorizontalAlignment to Left in the PrepareViewStyleInfo event.
Please refer to the attached sample that illustrates the same:
