Printing header RTL

[ShareDocs]

Hi,
is there a way to make the right header in the RadPrintDocument right aligned so if i have mixed language text (hebrew and english in my case) It will show it right...

currently i use this function (partly taken from this site - c-sharp-split-and-revers-sentence-with-two-languages):

public static string ProcessEnglishHebrewSentence(string sentence)
        {
            var ret = new List<string>();
            string[] words = sentence.Split(' ');

            var curHebrewList = new List<string>();
            var curEnglishList = new List<string>();
            bool curLangIsHebrew = false;
            string w;
            string reversed;

            for (int i = words.Length; i > 0; i--)
            {
                w = words[i - 1];
                if (System.Text.RegularExpressions.Regex.IsMatch(w, @"\p{IsHebrew}") && curLangIsHebrew) // we have a word in Hebrew and the last word was in Hebrew too
                {
                    curHebrewList.Add(w);
                }
                else if (System.Text.RegularExpressions.Regex.IsMatch(w, @"\p{IsHebrew}") && !curLangIsHebrew) // we have a word in Hebrew and the last word was in English
                {
                    if (curEnglishList.Any())
                    {
                        curEnglishList.Reverse();
                        ret.AddRange(curEnglishList);
                    } // reverse current list of English words and add to List
                    curEnglishList = new List<string>(); // create a new empty list for the next series of English words
                    curHebrewList.Add(w);
                    curLangIsHebrew = true; // set current language to Hebrew
                }
                else if (!System.Text.RegularExpressions.Regex.IsMatch(w, @"\p{IsHebrew}") && !curLangIsHebrew) // we have a word in English and the last word was in English
                {
                    if (System.Text.RegularExpressions.Regex.IsMatch(w, @"[a-zA-Z]"))
                    {
                        reversed = new string(w.Reverse().ToArray());
                        reversed = reversed.Replace("(", "^");
                        reversed = reversed.Replace(")", "(");
                        reversed = reversed.Replace("^", ")");
                    }
                    else
                        reversed = w;


                    curEnglishList.Add(reversed); // reverse and add it to the current series of English words
                }
                else if (!System.Text.RegularExpressions.Regex.IsMatch(w, @"\p{IsHebrew}") && curLangIsHebrew) // we have a word in English and the last word was in Hebrew
                {
                    if (curHebrewList.Any())
                    {
                        curHebrewList.Reverse();
                        ret.AddRange(curHebrewList); // add current list of Hebrew words to List of Lists
                    }
                    curHebrewList = new List<string>(); // create a new empty list for the next series of Hebrew words

                    if (System.Text.RegularExpressions.Regex.IsMatch(w, @"[a-zA-Z]"))
                    {
                        reversed = new string(w.Reverse().ToArray());
                        reversed = reversed.Replace("(", "^");
                        reversed = reversed.Replace(")", "(");
                        reversed = reversed.Replace("^", ")");
                    }
                    else
                        reversed = w;

                    curEnglishList.Add(reversed);
                    curLangIsHebrew = false; // set current language to English
                }
                else
                {
                    throw new Exception("there should be no other case...");
                }
            }
            if (curHebrewList.Any())
            {
                curHebrewList.Reverse();
                ret.AddRange(curHebrewList);
            }
            if (curEnglishList.Any())
            {
                curEnglishList.Reverse();
                ret.AddRange(curEnglishList);
            }

            return ret.Aggregate((a, b) => a + " " + b);
        }

I would like to know if there is a more elegant sollution

Hello Lior,

Thank you for writing.

The headers of a RadPrintDocument are three strings that are drawn in the same rectangle with alignment Left, Center and Right. I would need to see how you expect the text to be drawn and how it is actually drawn so I can advise as to how to approach this.

Looking forward to your reply.

All the best,

Hi,
the string variable contain:
לקרן: אי.בי.אי. (0B) (!)  אג"ח ללא מניות

and I want it to look like
אג"ח ללא מניות (B0) (!)  לקרן: אי.בי.אי.

The problem is when i combine hebrew and english...
when I copy the sentence to a text editor than the upper sentence is when i left align and the lower sentence is when i right aligned...

Hi Lior,

Thank you for writing back.

You can print the header yourself using RadPrintDocument's PrintPage event. Here is how the document is set up:

RadPrintDocument doc = new RadPrintDocument();
doc.PrintPage += doc_PrintPage;
doc.AssociatedObject = this.radGridView1;
doc.RightHeader = "לקרן: אי.בי.אי. (0B) (!)  אגח ללא מניות";
RadPrintPreviewDialog dialog = new RadPrintPreviewDialog(doc);

And here is the code to print the right header in RTL:

private void doc_PrintPage(object sender, System.Drawing.Printing.PrintPageEventArgs e)
{
    RadPrintDocument doc = (RadPrintDocument)sender;
    SizeF size = e.Graphics.MeasureString(doc.RightHeader, doc.HeaderFont);
    PointF location = new PointF(e.MarginBounds.Right - size.Width, e.MarginBounds.Top + (doc.HeaderHeight - size.Height) / 2);

    RadGdiGraphics gr = new RadGdiGraphics(e.Graphics);
    TextParams tp = new TextParams();
    tp.alignment = ContentAlignment.MiddleRight;
    tp.rightToLeft = true;
    tp.text = doc.RightHeader;
    tp.font = doc.HeaderFont;
    tp.foreColor = Color.Black;
    tp.paintingRectangle = new RectangleF(location, size);

    gr.FillRectangle(tp.paintingRectangle, Color.White);
    gr.DrawString(tp, size);
}

The gr.FillRectangle is to hide the default header printing.

I hope this will be useful. Should you have further questions, I would be glad to help.
