System.OutOfMemoryException in RadDocument

[Sergio]

Hi Telerik Team,

Im getting the execption: System.OutOfMemoryException in RadDocument with a huge string!!!

1)string text = sb.ToString();
2)RadDocument doc = new XamlFormatProvider().Import(text);
3)this.radRichTextBox.Document = doc;

My text is a table, something like this:

.....
    <t:Table GridColumnWidthsSerializationInfo="" LayoutMode="AutoFit" PreferredWidth="Auto" StyleName="TableGrid" TableIndent="0">
        <t:TableRow>
            <t:TableCell ColumnSpan="1" RowSpan="1">
                ...
            </t:TableCell>
        </t:TableRow>

        ..........


    </t:Table>


....

It always works, but now i have 20.000 rows in my table, and it crashes in : RadDocument doc = new XamlFormatProvider().Import(text) --> System.OutOfMemoryException


Any ideas how to workaround this limitation?


Thanks!!

Hi,

Working with tables that big is out of the scope of the RadRichTextBox control. If you share more details about your scenario we can suggest alternative approach. May be you can use the RadGridView control if it fits your needs.

Hi Telerik Team,

I tried with RadGridView but i still have the same problem.

My code:

private RadDocument CreateDocumentWithRadGridView()
{

    RadGridView gridView = new RadGridView()
    {
        ItemsSource = this.Model.currentGrid.ItemsSource
    };


    Paragraph paragraph = new Paragraph();
    paragraph.Inlines.Add(new InlineUIContainer(gridView, new System.Windows.Size(gridView.ActualWidth, gridView.ActualHeight)));

    Section section = new Section();
    section.Blocks.Add(paragraph);

    RadDocument document = new RadDocument();
    document.Sections.Add(section);

    document.MeasureAndArrangeInDefaultSize();
    return document;
}

It it possible to create a RadDocument from a wcf project ? 

Thanks!!

Hi Tiago,

What Alex meant was that you could try using RadGridView to preview the data instead of RadRichTextBox. RadGridView is better-suited for such a scenario, not only because it has the tabular look that you seem to after, but also because of its data processing abilities. The focus of RadRichTextBox, on the other hand, is on editing rich text documents, and large tables, as well as embedding complex UIElements in InlineUIContainers, is not recommended.
