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.
