posted

Hello,

Can anybody tell me how to validate ultragrid cell value which

 must be a unique single alphanumeric string and may not contain special characters e.g. ?, !, $ etc.

 

But The thing is that user should not allow to enter(type) other than alphanumeric char means if user can press @ it'll not show in gridcell .plz repl.its urzent.

 

thanks in advance.

    If you need to prevent the user from typing certain characters, then you have a couple of options.

    1) You could set an InputMask on the column.

    2) You could trap the KeyDown event and cancel certain keystrokes.

    Approach 1 is easier, but it also means that you have to enforce a length limit on the string. You have to specify, as part of the mask, the maximum number of characters that the user can enter.

    Option 2 is more flexible and gives you more control.
