use pattern matching for this.if you want to validate your input at the time of keypress then you have to do a little extra work on textBox_KeyPress event else apply your validation at the time when you control looses its focus

Check if this helps u, Following code snippet is an example for validation of textbox. similar way compare values with different ascii numbers i.e. for only characters, numeric values...etc.. //VALIDATION FOR TELEPHONE NUMBER bool valid5 = false; char[] name5=new char[20]; name5=textBox27.Text.ToCharArray(); int leng5=textBox27.Text.Length ; for(int i=0 ; i < leng5 ; i++ ) { if( ((Convert.ToInt32(name5[i])>='0')&&(Convert.ToInt32(name5[i])<='9'))||(Convert.ToInt32(name21[i])==32)) { valid5=true; } else { MessageBox.Show("TELEPHONE NUMBER: Enter the valid Telephone Number"); textBox27.Focus(); return; } }

Use a Validator with regular expression. there are lots of examples on the web.

I would like to check if user has entered ALT+10 or à , ä (UMALUT) or any english alphabets The code sample in previous thread by 'sharmit' did not work for me. Can you please point me the websites where I can find code sample for the same.

I want to basically check if user has entered any control characters like 1-32 or 127 ASCII value (Ex: ALT + 127) in the edit box. And discard the same. FYI this edit box should allow any other non english characters like French, German, Chinese, Japanese etc
