我有一个XAMDataGrid，用于通过以下代码填充报告。
其中 EGMList 是模型。在此处输入图像描述
报告.Xaml
<dataPresenter:XamDataGrid x:Name="datagdStatus" DataSource="{Binding EgmList}" DockPanel.Dock="Top"
HorizontalContentAlignment="Stretch" HorizontalAlignment="Stretch" GroupByAreaLocation="None" FontFamily="Arial" FontSize="11" Visibility="Hidden">
<dataPresenter:XamDataGrid.FieldLayoutSettings>
<dataPresenter:FieldLayoutSettings RecordSelectorLocation="None" AllowAddNew="False" AllowDelete="False" AutoGenerateFields="False" />
</dataPresenter:XamDataGrid.FieldLayoutSettings>
<dataPresenter:XamDataGrid.FieldLayouts >
<dataPresenter:FieldLayout >
<dataPresenter:FieldLayout.Fields>
<dataPresenter:Field Name="Id" Label="{x:Static p:resource.tab_report_machineid}" Width="1.8*" Visibility="Collapsed">
<dataPresenter:Field.Settings>
<dataPresenter:FieldSettings AllowEdit="False" LabelTextAlignment="Center" EditorStyle="{StaticResource TextEditor}" LabelTextWrapping="Wrap" />
</dataPresenter:Field.Settings>
</dataPresenter:Field>
<dataPresenter:Field Name="MacAddress" Label= "{x:Static p:resource.UID}" Width="4*">

</dataPresenter:Field.Settings>
</dataPresenter:Field>

<dataPresenter:Field.Settings>

</dataPresenter:Field.Settings>
</dataPresenter:Field>
<dataPresenter:Field Name="Status" Label="{x:Static p:resource.tab_redeem_status}" Width="5*" >
<dataPresenter:Field.Settings>
<dataPresenter:FieldSettings AllowEdit="False" LabelTextAlignment="Left" />
</dataPresenter:Field.Settings>
</dataPresenter:Field>
</dataPresenter:FieldLayout.Fields>
</dataPresenter:FieldLayout>
</dataPresenter:XamDataGrid.FieldLayouts>
</dataPresenter:XamDataGrid>
</DockPanel>
报告.Xaml.cs
private void btnAllStatusPrint_Click(object sender, RoutedEventArgs e)
{
if (RedeemVoucherViewModel.EgmList.Count != 0)
{
Report reportObj = new Report();
// set scale mode
reportObj.ReportSettings.HorizontalPaginationMode = HorizontalPaginationMode.Scale;
reportObj.PageHeaderTemplate = this.Resources["PagePresenterHeaderTemplate_small"] as DataTemplate;
// reportObj.PageContentTemplate = this.TryFindResource("basicContentTemplate") as DataTemplate;
string siteControllerName = RedeemVoucherView.getSiteControllerName();
// reportObj.PageFooter = "Total Machines :23";
reportObj.PageHeader = string.Format("{0} {2} {1}", siteControllerName, DateTime.Now.ToString("dd/MM/yyyy"), Environment.NewLine);
reportObj.ReportSettings.PageSize = new Size(3.13, 6);
// create section and add it to report's section collection
reportObj.ReportSettings.Margin = new Thickness(0, 0, 0, 0);
EmbeddedVisualReportSection section = new EmbeddedVisualReportSection(datagdStatus);
reportObj.Sections.Add(section);
reportObj.Print(true, false);
rteventLogger.WriteLog(TraceEventType.Information, "All Status report is printed", WMSTrace.ScopeTypes.Internal);
}
else
{
MessageBoxHelper.Show("No content available to print", MessageBoxImage.Information);
}
}
在上述函数调用中打印，并在报表网格中填充 EGMList 的内容。
我想在报告末尾有一个摘要标签，其中包含记录/临时股东大会的计数
尝试将其添加到页面页脚中，但没有运气，因为它在所有页面中打印。
还尝试从代码隐藏中添加不同的部分，但这也显示了一起占用不同的页面。
请对此提出任何建议？
不幸的是，
这不是一件容易的事情。
首先，我认为我只需要为Report定义一个新FooterTemplate，并根据页脚是否在最后一页上隐藏或显示页脚。
不幸的是，报告生成的方式是您不知道总共将生成多少页，因此在数据模板中，您不知道是否正在模板化最后一页。

解决方法
我只能为您提供解决方法。如果您不介意生成两次报告，这是可行的。首先，我们生成它，以便获得总页数，我们可以使用它设置FooterTemplate：
private void btnAllStatusPrint_Click(object sender, RoutedEventArgs e)
{
if (RedeemVoucherViewModel.EgmList.Count != 0)
{
Report reportObj = new Report();
// set scale mode
reportObj.ReportSettings.HorizontalPaginationMode = HorizontalPaginationMode.Scale;
reportObj.PageHeaderTemplate = this.Resources["PagePresenterHeaderTemplate_small"] as DataTemplate;
string siteControllerName = RedeemVoucherView.getSiteControllerName();
reportObj.PageFooter = string.Format("Total Machines: {0}", MyXamDataGrid.DataItems.Count);
reportObj.PageHeader = string.Format("{0} {2} {1}", siteControllerName, DateTime.Now.ToString("dd/MM/yyyy"), Environment.NewLine);
reportObj.ReportSettings.PageSize = new Size(3.13, 6);
// create section and add it to report's section collection
reportObj.ReportSettings.Margin = new Thickness(0, 0, 0, 0);
EmbeddedVisualReportSection section = new EmbeddedVisualReportSection(datagdStatus);
reportObj.Sections.Add(section);
var xamReportPreviewToGetTotalPageNumbers = new XamReportPreview();
xamReportPreviewToGetTotalPageNumbers.GeneratePreview(reportObj, false, false);
reportObj.PageFooterTemplate = GetDataTemplateForTotalPageNumbers(reportObj.PhysicalPageNumber);
reportObj.Print(true, false);
rteventLogger.WriteLog(TraceEventType.Information, "All Status report is printed", WMSTrace.ScopeTypes.Internal);
}
else
{
MessageBoxHelper.Show("No content available to print", MessageBoxImage.Information);
}
}
GetDataTemplateForTotalPageNumbers如下：
private DataTemplate GetDataTemplateForTotalPageNumbers(int totalPages)
{
var dataTemplate = new DataTemplate();
//set up the label
var labelFactory = new FrameworkElementFactory(typeof (Label)) {Name = "FooterLabel"};
labelFactory.SetValue(VisibilityProperty, Visibility.Collapsed);
labelFactory.SetValue(ContentProperty, new Binding());
dataTemplate.VisualTree = labelFactory;
var dataTrigger = new DataTrigger
{
Binding = new Binding("PhysicalPageNumber")
{
RelativeSource = new RelativeSource(RelativeSourceMode.FindAncestor)
{
AncestorType = typeof (ReportPagePresenter)
}
},
Value = totalPages
};
dataTrigger.Setters.Add(new Setter {
TargetName = "FooterLabel",
Property = VisibilityProperty,
Value = Visibility.Visible
});
dataTemplate.Triggers.Add(dataTrigger);
return dataTemplate;
}
我希望这有所帮助。不过，我会谨慎使用它。因为现在我们生成报表两次（一次用于获取总页码并设置正确的数据模板，该模板在正确的页面上显示页脚，再次打印它）它会导致两次时间，所以如果你有一个巨大的网格，这会冻结 UI 一段时间。
