How to know if the Selection is Multiline or Singleline

[Kushagra]

How do we know programmatically that the selection done by the user is a single line selection and doesnt contain any combination. We want to know how will we identify if the user has selected table/images or plain text.

Hi Kushagra,

Thank you for contacting us!

If you are going to identify the elements in the user's selection, I would suggest you to create a new document from the selection. Then you should enumerate its table/image elements and determine whether they exist. 

The following code-snippet demonstrates how this could be accomplished:

if (!this.radRichTextBox.Document.Selection.IsEmpty)
{
    RadDocumentEditor documentEditor = new RadDocumentEditor(new RadDocument());
    documentEditor.InsertFragment(new DocumentFragment(this.radRichTextBox.Document.Selection));

    if (documentEditor.Document.EnumerateChildrenOfType<Table>().Count() > 0)
    {
        MessageBox.Show("Contains table");
    }
    if (documentEditor.Document.EnumerateChildrenOfType<ImageInline>().Count() > 0)
    {
        MessageBox.Show("Contains image");
    }
}

I hope this helps!
