Business requirements:

In the form construction, there is no lack of the system to automatically judge whether the menu function of the form is available or not according to some data. This may not be a difficult thing for non-professional developers.

To solve this kind of problem, Metrics Rapid Development platform provides a set of smart wizards that rookies can use freely to build intelligent wizards. The following mainly explains how to realize the display and hiding control of the grid component focus line data to the menu function.

Application scenarios:

Example: warehouse management, when we select the goods that have been audited and completed, we need to implement the read-only functions of modification, deletion and audit. As shown in the figure:

On the contrary, unaudited data is selected to achieve read-only sales audit, and other operations are available. As shown in the figure:

The above is the display effect of the interface. Let's take a look at the background code (it is not as complicated as we thought, and rookies can use it freely):

Open the form Design-event Management-Smart parts-input order, and click the focus line data change event to see:

Of course, beginners can also use smart wizards to guide settings to achieve functions.

Step: first click on the event management smart wizard, open the smart code wizard on the left side of the method and property name list select: smart form-Settings function available

Click on the auxiliary settings, and the function name drops down the selection box to select the corresponding function.

Check whether to set the feature available (True: feature available; False: feature not available)

Then click the OK button to complete the settings.
