Namespace: MindFusion.Reporting.Wpf
Assembly: MindFusion.Reporting.Wpf

 Syntax

C#

public static Report FromStream (
    Stream stream,
    string key
)

Visual Basic

Public Shared Function FromStream( _
    stream As Stream, _
    key As String _
) As Report

 Parameters

stream

A System.IO.Stream containing Xaml report definition.

key

Key value of a report in resource dictionary.

 Return Value

A Report instance.

 Remarks

The Xaml file could contain a ResourceDictionary with multiple report definitions. In that case, FromStream returns the one whose x:Key is set to the key argument value. Do not set Name properties when loading reports from an external file, or WPF's XamlLoader will throw an exception. Instead, you can set InternalName attribute if needed, which internally sets same Name value of WPF elements:

Xaml

<ResourceDictionary>
  ...
  <r:Report x:Key="report1">
    ...
    <r:DataRange r:InternalName="OrdersRange">

If you need to define just one report in the Xaml file, you can keep it as the root element. In that case, the key argument is ignored, and you can freely set Name attributes:

Xaml

<r:Report ...

  xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
  xmlns:r="http://mindfusion.eu/reporting/wpf">    ...
    <r:DataRange Name="OrdersRange">
