在Dev GridView控件中，数据库中表数据日期都是长日期格式（yyyy-MM-dd HH:mm:ss），但显示在控件变成短日期格式（yyyy-MM-dd),金额显示要显示精确的数值，
比如80.00，90.15等，但在 dev gridView中只是显示80，90
1、解决日期显示问题的代码： 设置日期的displayformat，editFormat,EditMask
/// <summary>
/// 设置时间显示格式
/// </summary>
/// <param name="dateEdit">日期时间的父类,就是日期控件</param>
public static void SetDateTime(DateEdit dateEdit)
{
dateEdit.Properties.DisplayFormat.FormatString = "yyyy-MM-dd HH:mm";
dateEdit.Properties.DisplayFormat.FormatType = DevExpress.Utils.FormatType.DateTime;
dateEdit.Properties.EditFormat.FormatString = "yyyy-MM-dd HH:mm";
dateEdit.Properties.EditFormat.FormatType = DevExpress.Utils.FormatType.DateTime;
dateEdit.Properties.Mask.EditMask = "yyyy-MM-dd HH:mm";
}
2、解决金额显示精确问题
/// <summary>
/// 设置价格的显示格式
/// </summary>
/// <param name="spinEdit"></param>
public static void SetMoney(AokaSpinEdit spinEdit)
{
spinEdit.Properties.DisplayFormat.FormatString = "{0:N2}";
spinEdit.Properties.DisplayFormat.FormatType = DevExpress.Utils.FormatType.Numeric;
spinEdit.Properties.EditFormat.FormatString = "{0:N2}";
spinEdit.Properties.EditFormat.FormatType = DevExpress.Utils.FormatType.Numeric;
}
上面是在明细中，调用控件的名称，设置在初始化类，比如 Hepper.SetDateTime(startDate);
3.解决列表显示时日期和金额的问题
/// <summary>
/// 设置列表数据的日期格式
/// </summary>
/// <param name="sender"></param>
/// <param name="e"></param>
public static void gridView1_RowCellStyle(object sender, DevExpress.XtraGrid.Views.Grid.RowCellStyleEventArgs e)
{
if (e.Column.FieldName == "创建日期" || e.Column.FieldName == "创建时间" || e.Column.FieldName == "StartDate" || e.Column.FieldName == "EndDate" || e.Column.FieldName == "发货时间" || e.Column.FieldName == "发生时间" || e.Column.FieldName == "制单日期" || e.Column.FieldName == "单据日期" || e.Column.FieldName == "BillDate")
{
e.Column.DisplayFormat.FormatString = "yyyy-MM-dd HH:mm:ss";
}
}
/// <summary>
/// 设置列表数据中价格的格式
/// </summary>
/// <param name="sender"></param>
/// <param name="e"></param>
public static void gridView1_RowCellStyle1(object sender, DevExpress.XtraGrid.Views.Grid.RowCellStyleEventArgs e)
{
if (e.Column.FieldName == "价格元" || e.Column.FieldName == "Price" || e.Column.FieldName == "Money" || e.Column.FieldName == "应付款" || e.Column.FieldName == "应收款" || e.Column.FieldName == "单价" || e.Column.FieldName == "金额" || e.Column.FieldName == "总金额" || e.Column.FieldName == "合计金额")
{
e.Column.DisplayFormat.FormatString = "{0:N2}";
e.Column.DisplayFormat.FormatType = DevExpress.Utils.FormatType.Numeric;
}
}
在窗体下，是这样的调用的
//列表日期显示格式
this.gridView_List.RowCellStyle += new DevExpress.XtraGrid.Views.Grid.RowCellStyleEventHandler(Heppler.gridView1_RowCellStyle);
//列表价格显示格式
this.gridView_List.RowCellStyle += new DevExpress.XtraGrid.Views.Grid.RowCellStyleEventHandler(Heppler.gridView1_RowCellStyle1);
4、设置列表数据状态的显示颜色
/// <summary>
/// 设置状态的颜色样式
/// </summary>
/// <param name="sender"></param>
/// <param name="e"></param>
public static void gridView1_RowCellStyle2(object sender, DevExpress.XtraGrid.Views.Grid.RowCellStyleEventArgs e)
{
if (e.Column.FieldName == "单据状态") {
if (e.CellValue != null && e.CellValue.ToString() == "已完成") {
e.Appearance.BackColor = Color.Green;
}
}
if (e.Column.FieldName == "结算状态")
{
if (e.CellValue != null && e.CellValue.ToString() == "已结算")
{
e.Appearance.BackColor = Color.Red;
}
}
}
在窗体下，是这样的调用的
//列表日期显示格式
this.gridView_List.RowCellStyle += new
DevExpress.XtraGrid.Views.Grid.RowCellStyleEventHandler(Heppler.gridView1_RowCellStyle2);
5、设置dev gridView中自动列宽适应的属性
gridView_List.OptionsView.ColumnAutoWidth = false;
Dev gridView中设置自适应列宽和日期显示格式、金额的显示格式
