Well, regular expressions is a tricky topic and I really am not sure if I can help a lot here, but I guess you can always use Google to formulate your expression.

I can also suggest one great too, Regulator, that helps you build regular expressions for you - you may find this useful.

hi ..

Thanks in advance...

Hello Priya,

It really depends on where you want your validation to play. If you want the grid to not show certain data in read-only (default) mode, then you will need to filter the datasource first yourself (using SQL for example) and just then bind the grid.

If you are using defualt cell editors you can check out this:

If you are using RowEditTemplate, you can check out the following forum thread

Finally, I also recommend the following great article on how to implement UltraWebGrid in production (full blown) - part of this deals exactly with validation and getCellById methods:
