PXGridColumn
属性设置为Type
的 Icon
用于在PXGrid容器中显示图像:
<px:PXGridColumn DataField="ImageUrl" Width="300px" Type="Icon" />
这样的专栏能够显示来自两个来源的图像:
精灵
row.ImageUrl = string.IsNullOrEmpty(row.ImageUrl) ? "main@Fail" : "main@Success";
网址:
row.ImageUrl = @"http://www.acumatica.asia/acumaticawwwsite-acumaticainc.netdna-ssl.com/wp-content/uploads/2014/09/acumatica-2.png";
要在Inventory ID选择器查找中添加Icon
类型的列,应该:
为SOLine DAC声明扩展类并扩展Inventory ID选择器的列列表:
[PXNonInstantiatedExtension]
public class SO_SOLine_ExistingColumn : PXCacheExtension<PX.Objects.SO.SOLine>
{
#region InventoryID
[PXMergeAttributes(Method = MergeMethod.Append)]
[PXCustomizeSelectorColumns(
typeof(PX.Objects.IN.InventoryItem.inventoryCD),
typeof(PX.Objects.IN.InventoryItem.descr),
typeof(PX.Objects.IN.InventoryItem.itemClassID),
typeof(PX.Objects.IN.InventoryItem.itemStatus),
typeof(PX.Objects.IN.InventoryItem.itemType),
typeof(PX.Objects.IN.InventoryItem.baseUnit),
typeof(PX.Objects.IN.InventoryItem.salesUnit),
typeof(PX.Objects.IN.InventoryItem.purchaseUnit),
typeof(PX.Objects.IN.InventoryItem.basePrice),
typeof(PX.Objects.IN.InventoryItem.imageUrl))]
public int? InventoryID { get; set; }
#endregion
}
对于新列,请将Type
属性值设置为Icon
:
<px:PXSegmentMask ID="edInventoryID" runat="server" DataField="InventoryID">
<GridProperties>
<Columns>
<px:PXGridColumn DataField="ImageUrl" Type="Icon" Width="300px" AutoGenerateOption="Add" />
</Columns>
</GridProperties>
</px:PXSegmentMask>
但是,这似乎不足以在选择器查找中显示附加到库存项目的图像。我们接下来的步骤是为InventoryItem DAC定义未绑定的自定义字段,并使用有效的URL填充它以显示附加的图像。
请注意,下面的示例可能会导致性能显着下降。在现实生活中,您必须使用缩小版本的图片(缩略图)和存储URL,以通过Acumatica数据库中的自定义数据库绑定字段访问它们。
为InventoryItem DAC实现扩展类,并声明未绑定的ThumbnailURL字段以存储附加图像的URL:
public class InventoryItemExt : PXCacheExtension<InventoryItem>
{
public abstract class thumbnailURL : IBqlField
{ }
[PXString]
public string ThumbnailURL { get; set; }
}
在SOOrderEntry BLC扩展中,订阅RowSelecting处理程序并使用有效URL填充未绑定的ThumbnailURL字段以显示附加图像:
public class SOOrderEntryExt : PXGraphExtension<SOOrderEntry>
{
public override void Initialize()
{
Base.RowSelecting.AddHandler<InventoryItem>(InventoryItemRowSelecting);
}
public void InventoryItemRowSelecting(PXCache sender, PXRowSelectingEventArgs e)
{
var row = e.Row as InventoryItem;
if (row != null && !string.IsNullOrEmpty(row.ImageUrl))
{
Guid[] files = PXNoteAttribute.GetFileNotes(sender, e.Row);
var fm = PXGraph.CreateInstance<PX.SM.UploadFileMaintenance>();
foreach (Guid fileID in files)
{
PX.SM.FileInfo fi = fm.GetFileWithNoData(fileID);
if (fi.FullName == row.ImageUrl || fi.Name == row.ImageUrl)
{
row.GetExtension<InventoryItemExt>().ThumbnailURL =
ControlHelper.GetAttachedFileUrl(null, fileID.ToString());
break;
}
}
}
}
}
将ThumbnailURL列的Type
属性设置为Icon
:
<px:PXSegmentMask CommitChanges="True" ID="edInventoryID" runat="server" DataField="InventoryID" AllowEdit="True" >
<GridProperties>
<Columns>
<px:PXGridColumn DataField="ThumbnailURL" Width="300px" AutoGenerateOption="Add" Type="Icon" />
</Columns>
</GridProperties>
</px:PXSegmentMask>
