需要改变GridView字体大小时，设置font是无效的，只能通过设置RowHeight的属性值来实现：

Dev gridview 调整字体大小

private void InitControl()

{

//调整表头字体大小

this.gdvFault.Appearance.HeaderPanel.Font = new Font("Tahoma", 18, FontStyle.Regular, GraphicsUnit.Pixel);

//调整行字体大小

this.gdvFault.Appearance.Row.Font = new Font("Tahoma", 18, FontStyle.Regular, GraphicsUnit.Pixel);

}

GridView的focusRowChanged事件(获取选中行的某列值)：

private void gdvWIPMain_FocusedRowChanged(object sender, DevExpress.XtraGrid.Views.Base.FocusedRowChangedEventArgs e)

{

if (e.FocusedRowHandle >= 0)

{

GlobalVariable.gsCurrentLotID = this.gdvWIPMain.GetFocusedRowCellValue("LOT_ID").ToString();

}

else

{

GlobalVariable.gsCurrentLotID = "";

}

}
