The Code methods group provides access to the most commonly customized functions for the currently selected control in the Layout Editor. For data bound controls such as a textbox displayed on the Add or Edit page, the Code methods show the Set, Get and Validate functions. Similarly, selecting a button control shows its Click function, or selecting a dropdown list shows its SelectedIndexChanged, Populate and other functions. Zooming out to the Table Control or the Record Control level will display functions such as CreateWhereClause, LoadData, DataBind and SaveData that are relevant to the selected controls.
Clicking ‘…’ button on Property Sheet for any method opens code editor. Modification of the code in the code editor automatically places a copy of the function in Section 1 of the underlying code file. At any point, clicking Restore will remove all the customizations and reset the function to its originally created code. Subsequent builds will also preserve the customizations, and the changes made will never be overwritten, unless explicitly restored.
Clicking the Code Docs button in the code editor opens documentation related to the specific method.
