Hi

How to do this with Rad Text Box:

1- Prevent Data duplication when insert a new record (something like user name) , so say if the user entered a user name which is already exist then he ll get an error message (i know i can do that back in the database by making the column unique but then on the client side the sql error message will appear which will look ugly.

2- is there any option to make all the inputs UPPER CASE regardless the user inputs.

Thanks

Hi grand lorie,

This task is out of the scope of RadTextBox - you need to check for duplicates yourself with a separate query (during postback) and force the user to enter another value if the username exists.

Thanks Demo for your answer

but how can i do that with the query? can you give some lights?

is there anyway to do that with the validation controls? to compare the inputs to the column data?

I think this is very important feature which should be included! for a shopping site (as example) which has a lot of products and keep adding, it is very important to make sure that this new item is not already on the database..!!

Hello,

Well, after postback you should get the input value with RadTextBox1.Text and make a SELECT query in the datasource to check whether this value is already present.

This is not something RadTextBox should do automatically, as it doesn't know anything about how its value is handled by the application.
