Given the following code example, is there a way to access "RadTextBox_Name" in code-behind prior to initiating an Edit operation on the record? e.g. in the RadGrid onItemCommand event (CommandName="Edit") is there a way to manipulate the attributes of RadTextBox_Name prior to the pop-up appearing? My real-world application is a bit more complicated than this (e.g. I have several fields and want to have some enabled/disabled based on values in other fields, etc.) but for purposes of my question, the below code example is adequate.
