I've recently been given the task of turning some labels that we use to put on hardcopy documents into format that can be printed with a small label printer that takes 62mm label tape.

Basically, the user types all the data for the label into a form. I then store the details for them in a grid. When they are ready to print the label, they click a print button that is in my grid. The data for the label is put into a pdf and they print it from the pdf.

The label printer uses a continuous roll or tape so that the text fields can be as long as they want. I'm currently putting all the details into a Table object and then I draw the table with a width of 62mm.

How can I find what the height of the table would be when the width is 62mm so that I can set the height of the page?

 

public RadFixedDocument CreateDocument()
        {
            RadFixedDocument document = new RadFixedDocument();
            RadFixedPage page = document.Pages.AddPage();
            page.Size = new Size(Telerik.Windows.Documents.Media.Unit.MmToDip(62), Telerik.Windows.Documents.Media.Unit.MmToDip(100));
            FixedContentEditor editor = new FixedContentEditor(page);

            Table table = CreateDetailsTable();
                        
            editor.DrawTable(table, Telerik.Windows.Documents.Media.Unit.MmToDip(62));

            return document;
        }

Hello Johannes,

Thank you for your interest in Telerik Document Processing.

You can achieve this by measuring the table size after the table content is added and use the DesiredSize property to get the height of the table:
RadFixedDocument document = new RadFixedDocument();
 
Table table = CreateDetailsTable();
 
double widthInDip = Telerik.Windows.Documents.Media.Unit.MmToDip(62);
table.Measure(new Size(widthInDip, double.PositiveInfinity));
 
RadFixedPage page = document.Pages.AddPage();
page.Size = new Size(widthInDip, table.DesiredSize.Height);
 
FixedContentEditor editor = new FixedContentEditor(page);
editor.DrawTable(table, widthInDip);

I hope this helps.

Regards,
Georgi
