Hi Scott,
Thanks for your interest in Syncfusion Products.
1. The below can be used to hide columns in GridDataBoundGrid.
this.gridDataBoundGrid1.Model.HideCols[1] = true;
2. To avoid the addnew row at the bottom, set the below property setting
this.gridDataBoundGrid1.EnableAddNew = false;
3. To change the font/display appearance for the column header cells, the PrepareViewStyleInfo event has to be handled. Refer the sample for more details.
Please refer the sample below that helps in doing the above mentioned tasks.
