visual studio - Change colour and size of a certain string in a textblock (Windows Phone 7) in VB.net -

-

hi have button (btnadd) adds content of textbox (txtname) textblock (lblname). want add date textblock when btnadd pressed want different font size , colour. far code looks like

lblname.text = txtname.text " " + datetime.now

i want datetime.now different size , colour. possible?

edit: instead of label need display in listbox new code need on is:

listbox1.items.add(txtname.text " " + datetime.now)

what want assign inlines rather text:

lblname.inlines.clear(); lblname.inlines.addrange(new inline[] {     new run(txtname.text + " ")     {         foreground = new solidcolorbrush(color.black)     },     new run(datetime.now.tostring())     {         foreground = new solidcolorbrush(color.green)     } });

you can (and should) bind run's directly xaml:

<textblock>     <textblock.inlines>         <run text="{binding name}" foreground="black" />         <run text=" " foreground="black" />         <run text="{binding now}" foreground="green" />     </textblock.inlines> </textblock>
