I have a RadTextBox data bound to an Decimal field (12,9). When the user hits the "DELETE" button on their keyboard to blank out that field's value, the value is cleared out, but the user cannot exit the control until the user enters a value of some kind (Alpha or Numeric). This is not the desired outcome that we would like. What I would like to happen is for the bound field's value to be set to null. Can anyone help me with code sample please. I have tried also using a MaskedEditBox with a MaskType of Numeric and Mask of F9, but this also gives us undesired results (0.0000000) when user clicks the DELETE button on their keyboard.
