AddHandler Cb.CheckedChanged, AddressOf cb_CheckedChanged

End If

End Sub

Restrict the input to specific language

Hi there..

Normally we have English letter keyboards with other languages support. And we can switch between languages by pressing Alt-Shift or Ctrl-Shift, or by selecting the input language from the language bar, and then we can start typing in the selected language.

Currently I am developing a web page where the user should fill some fields in two languages (i.e., filling name in English letters and then filling name in Arabic letters). Normally in this case, the user should fill the name in English and then switch the keyboard language from the keyboard or the language bar.

I want to restrict the input the Arabic text box to accept only Arabic , put also you can pest arabic word,,
I am using ASP.NET AJAX Q1 2012 ..

is there any way in Rad Control to do that?

Thanks..
