I have set automatic value for a textbox like "RA-'.

At the end of this text, the user should be able to add a no., like RA-01..

In ADD button click event, I set the value of text to RA and did a setfocus on the textbox.

How should I do this to put the cursor at the end of the text RA.. rather than put the cursor before the text.. ?

If the text is RA-01.. and so forth.. how can I automatically set the value of the text box to RA-02.. when user clicks the ADD button?

Any help? TIA.
