try this:

1. ^[-]?([1-9]{1}[0-9]{0,}(\\.[0-9]{0,2})?|0(\\.[0-9]{0,2})?|\\.[0-9]{1,2})$ for numbers with decimals.

2. ^[1-9]{1}$|^[1-4]{1}[0-9]{1}$|^1000000$ for integers between 1 and 1000000.

Is this what you were looking for?...

Do you mean you don't want any spaces in the TextBox input? Just numbers and letters and other characters?

Hi all,

I happen to be trying out the Dxperience suite from DevExpress. I have encountered a few problems without a way forward. First, if there's anyone with a little bit of experience with the XtraGrid, I would like to know how to disable editing of a particular cell for a particular row as opposed to the entire column for all rows. A cell could be made read only depending on values of other cell(s) on the same row.
