我在某些条件下在网格的特定单元格中设置图像，但是图像重复或显示为平铺，没有显示单个图像，我只想显示一个，我无法理解为什么会发生这种情况

屏幕截图：

这是我的密码：

private void PendingTask_RowCellStyle(object sender, DevExpress.XtraGrid.Views.Grid.RowCellStyleEventArgs e)
{
    try
    {
        if (e.RowHandle < 0)
            return;

        int con = PendingTaskGridView.SortedColumns.Count;

        DataModel.TaskToConfirm task = this.PendingTaskGridView.GetRow(e.RowHandle) as DataModel.TaskToConfirm;

        if (task == null)
            return;

        if (e.Column.Name.Equals("gridColBilling", StringComparison.InvariantCultureIgnoreCase))
        {

            SetTaskStatusColor(e, task);
            //SetTimeDifferenceColor(e, task);
        }

        if (e.Column.Name.Equals("gridColPunctuality", StringComparison.InvariantCultureIgnoreCase))
        {

            SetPunctualityColor(e, task);
            //SetTimeDifferenceColor(e, task);
        }

        if (e.Column.Name.Equals("gridColAttendance", StringComparison.InvariantCultureIgnoreCase))
        {

            SetAttendanceColor(e, task);
            //SetTimeDifferenceColor(e, task);
        }


    }
    catch (Exception ex)
    {
        ApplicationExceptions.HandleAppExc(ex);
    }
}

在这种情况下，

AppearanceObject.Image

属性用于指定单元格背景的填充模式。因此，您可以看到所有这些图像副本。
我建议您使用事件在单元格边界内绘制单个图像，或者使用编辑器指定属性以基于单元格值显示不同的图像

相关帮助文章：

在资深同事的帮助下，我自己用Event和Event解决了这个问题

下面是DataSourceChanged事件，在该事件中，我将来自code behind的图像列添加为未绑定列，并将其

UnboundType

设置为

Object

，并且必须将

ColumnEdit

属性设置为

ResposityItemPictureEdit

感谢您的回复，但我通过其他方式解决了这个问题，我也将其发布为答案NP，但根据我的经验，使用RepositoryImageCombobox比创建未绑定列要有效得多…我对devexpress控件非常陌生，我的高级同事指导我这样做…：）但我感谢您的努力…：）
