Hi Martin,
Thank you for using Syncfusion products,
It is not possible to set alignment of whole column using PdfGrid, we can achieve this only by setting to each columns separately. However, this feature is available in PdfLightTable. Here we can set Default Style property for alignment of whole column. I have attached a simple sample for your reference below, please have a look through it and let us know if you have any other queries.
Code Snippet:
//Create Light Table
PdfLightTable lightTable = new PdfLightTable();
//Set Data Table
lightTable.DataSource = dataTable;
//Set default style for whole grid column
lightTable.Style.DefaultStyle.StringFormat = new PdfStringFormat(PdfTextAlignment.Center);
