this would make every chat typed in the text box appear in Upper case
But this handles only the display, the actual text is still how the user
typed it. So, before saving/processing the data at server side you may change
it to uppercase
string strUpper = TextBox1.Text.ToUpper();
************************************
If you need every char typed in Textbox instantly changed to Uppercase
you may use the OnKeyPress(or onkeydown) event in Javascript and change the
current char(event.keyCode) to uppercase
************************************
If you need the entire string to be changed to Uppercase , once the user
finished typing
you may use the onblur event in Javascript and change the content of textbox
to uppercase
hope this helps .. pls let me know if you have any questions
