Rendering to JSON

In This Topic

JavaScript Object Notation (JSON) is a text-based data format in which the data is stored in the hierarchical form. You can use the JsonRenderingExtension to render your report in this format.

The following steps provide an example of rendering a report in the Json format.

Create a new Visual Studio project.
In the New Project dialog that appears, select ActiveReports 14 Page Report Application and specify a name for the project in the Name field.
Click OK to create a new ActiveReports 14 Page Report Application. By default a Page report is added to the project.
Add reference to GrapeCity.ActiveReports.Export.Xml package in the project.
On the Form.cs or Form.vb that opens, double-click the title bar to create the Form_Load event.
Add the following code inside the Form_Load event.

Visual Basic.NET code. Paste INSIDE the Form Load event.	Copy Code
' Provide the page report you want to render. Dim report As New GrapeCity.ActiveReports.PageReport() Dim reportDocument As New GrapeCity.ActiveReports.Document.PageDocument(report) ' Create an output directory. Dim outputDirectory As New System.IO.DirectoryInfo("C:\MyJSON") outputDirectory.Create() ' Provide settings for your rendering output. Dim jsonSettings As New GrapeCity.ActiveReports.Export.Text.Page.JsonRenderingExtension.Settings() jsonSettings.Formatted = True ' Set the rendering extension and render the report. Dim jsonRenderingExtension As New GrapeCity.ActiveReports.Export.Text.Page.JsonRenderingExtension() Dim outputProvider As New GrapeCity.ActiveReports.Rendering.IO.FileStreamProvider(outputDirectory, System.IO.Path.GetFileNameWithoutExtension(outputDirectory.Name)) ' Overwrite output file if it already exists. outputProvider.OverwriteOutputFile = True reportDocument.Render(jsonRenderingExtension, outputProvider, jsonSettings)

Visual Basic.NET code. Paste INSIDE the Form Load event.

Copy Code

' Provide the page report you want to render.
Dim report As New GrapeCity.ActiveReports.PageReport()
Dim reportDocument As New GrapeCity.ActiveReports.Document.PageDocument(report)

' Create an output directory.
Dim outputDirectory As New System.IO.DirectoryInfo("C:\MyJSON")
outputDirectory.Create()

' Provide settings for your rendering output.
Dim jsonSettings As New GrapeCity.ActiveReports.Export.Text.Page.JsonRenderingExtension.Settings()
jsonSettings.Formatted = True

' Set the rendering extension and render the report.
Dim jsonRenderingExtension As New GrapeCity.ActiveReports.Export.Text.Page.JsonRenderingExtension()
Dim outputProvider As New GrapeCity.ActiveReports.Rendering.IO.FileStreamProvider(outputDirectory, System.IO.Path.GetFileNameWithoutExtension(outputDirectory.Name))

' Overwrite output file if it already exists.
outputProvider.OverwriteOutputFile = True

reportDocument.Render(jsonRenderingExtension, outputProvider, jsonSettings)
