[Luis]

good morning;

I need help to export data from gridview but have too many columns and the export file looks like attachment.
I used the classes of this example  http://demos.telerik.com/silverlight/#GridView/PrintAndExportWithRadDocument
I wanna export in horizontal and use two or more pages for better data presentation. how can do that?

thanks have a nice day.

Hello Luis,

There are several options you can pursue:

• Export in a Landscape orientation or with larger PageSize of the Sections.
• If you still need to split the number of columns per page for example 10 columns to display in the first page and next 20 on another, you will need to implement custom logic as this is not supported out of the box. 
• Have you considered using our Reporting product which provides advanced printing capabilities?

I hope this helps.

ok,I done that, but how I do for hierarchical gridview, do you have a example project or demo for print and export a hierarchical gridview? with the same code does not print the child rows.

Hello Luis,

For a practical example on how to export RowDetails you can check our ExportingRowDetails Silverlight demo. You will need to combine it with the PrintAndExportWithRadDocument printing demo.

I am suggesting this demo because RowDetails is the recommended approach for displaying hierarchical data in GridView. 

I hope this helps.

there a way to perform the export in the background, without use the ui thread?
because with this method the user interface is blocked until the export is done, and busyindicator is frozen.

Hello,

You can export data with RadSpreadProcessing. The model is completely independent from UI. You can check this online demo as an example on how to export data.

How does it meet your needs?

how export to word with RadSpreadProcessing? i can't find the wordprovider.
in the example not exported to word

[Dimitrina]

Hello,

I am afraid you cannot export to Word with RadSpreadProcessing. In Silverlight, you can export to .docx with RadDocument. Please check the Print and Export with RadDocument online demo for an example.

I need use commands to leave aside the ui thread? I use the logical with a class instance but the UI still freezing

[Dimitrina]

Hi,

When you are using an instance of RadGridView to create a document, you need the UI Thread because of the UI control (RadGridView).
 
In case, you do not need access to UI elements, you can create the document in a different thread similar to:

RadDocument doc = new RadDocument();
var thread = new Thread(() =>
{
    PdfFormatProvider provider = new PdfFormatProvider();
    HtmlFormatProvider htmlProvider = new HtmlFormatProvider();

    doc = htmlProvider.Import(someHtml);
    buffer = provider.Export(doc);
});
thread.SetApartmentState(ApartmentState.STA);
thread.Start();
thread.Join();

Regarding the export itself (RadGridView.Export()), I can suggest you checking the Async Export documentation.

how can I get the width of the raddocument for determine the number of columns can I put in it? some property or method

[Petya]

Hello Luis,

You can obtain the width on a per-section basis using the following code:

double availableWidth = this.radRichTextBox.Document.Sections.First.PageSize.Width;

I hope this helps.
