how to calculate the textbock height and width in on load if i create textblock from code?

Question

TextBlock tbl= new TextBlock();
tbl.text="Kishore";

double x=tbl.ActualHeight;
double y=tbl.ActualWidth;

If i execute the code from the loaded event in Metro - winRT will return 0 for both.

How can I get the ActualWidth in the Loaded or SizeChanged event?

WPF had methods like arrange/measure, you gave available space and got dimensions as a result. Isn't there something similar in Jupiter? — Filip Skakun, May 12 '12 at 00:30

Call Measure() then Arrange() and then ActualWidth and ActualHeight will be updated.

Can also do this via

UpdateLayout();
testBlock.ActualWidth

This could be useful when calculating multiple objects heights and widths.

TextBlock tbl = new TextBlock();
tbl.Text = "Kishore";

tbl.Measure(new Size(0, 0));

double x = tbl.ActualHeight;
