how to measure width that has to be displayed in textblock? and how to make it autosize?

Answer 1

Textblocks that have no height or width specified will expand automatically until they fill their container. So try that.

Answer 2

You can get the size of a text using these solutions :

Solution 1

You could FormattedText to measure the size of text, here is an example:

String text = "Here is my text";
Typeface myTypeface = new Typeface("Helvetica");
FormattedText ft = new FormattedText(text, CultureInfo.CurrentCulture, 
        FlowDirection.LeftToRight, myTypeface, 16, Brushes.Red);

Size textSize = new Size(ft.Width, ft.Height);

Solution 2

Use the Graphics class (found here ):

System.Drawing.Font font = new System.Drawing.Font("Calibri", 12, FontStyle.Bold);
Bitmap bitmap = new Bitmap(1, 1);
Graphics g = Graphics.FromImage(bitmap);
SizeF measureString = g.MeasureString(text, font);

Here you are !
