I am using a RadGrid with GridNumericColumns, but I can reproduce this using just a RadNumericTextbox on a page.
IE10, IE7, Chrome, Firefox
When entering a decimal value into a RadNumericTextbox, if there are no values greater than 0 to the left of the decimal point, and the first non-zero digit is seven digits to the right of the decimal point, the number will be displayed in the field in scientific notation on focus. 0.0000007 will be displayed as 7e-7 if the user enters the number, selects outside the textbox, and then selects the textbox again. I would like it to remain in standard decimal notation.
The user in the previous thread seemed to be having an identical issue. Perhaps this bug has been reintroduced?
