I have a textbox in WPF window to show the path of file and browse button beside the textbox, I am selecting a file from (tfs) browser and I want to show the full path aligned from right side but it is showing from left side only. The Image show the path showed from left

I tried HorizontalAlignment,VerticalAlignment,HorizontalContentAlignment but nothing is helping.

I want to display it from right end.

I have referred

Show right end of text line in TextBox

TextBox.TextAlign right-side alignment has no effect in certain conditions?

Can anyone Help?

OK, so its not that trivial as setting a property on text box what you can do is declare this method:

private void ScrollToEnd()
{
    var sv = (ScrollViewer)txtSourceFile.Template.FindName("PART_ContentHost", txtSourceFile);
        sv.ScrollToHorizontalOffset(sv.ExtentWidth);
}

And call it whenever your textbox value is changed.

I had the same problem and added a method for the Loaded and TextChanged event

<TextBox Loaded="FolderTB_ScrolltoEnd" TextChanged="FolderTB_ScrolltoEnd" ... />

and for setting the offset

private void FolderTB_ScrolltoEnd(object sender, EventArgs e)
    {
        ((TextBox)sender).ScrollToHorizontalOffset(((TextBox)sender).ExtentWidth);
    }
