For example, in this example we add a queryfilter which acts like a where clause on the Dynamics AX generated query.ĭo users want to close the form.
This is where you will often make changes to just to just an individual data source. You can often dynamically change data sources here, so you could choose to load one data source based on a set of circumstances So maybe, for just this one form, you want to filter customers by their groups – easily done by going into this method (aka event) and changing things.
Here you can make changes to the way that the form grabs data without actually changing the core data source information. You can also populate variables that you will use to alter programmability throughout your class.Įach form has a connection to data known as the data source. Think of this as the starting point for everything. This is where you will populate default values or add runtime controls. Most Common Form Events that you will mess with (in the order that they are fired) Some of these levels have their own sublevels of events, but I’ll stick with 3 levels for now.

In order to understand how to code in Dynamics AX, you need to understand the event SEQUENCE at 3 different LEVELS. The key was to understand the eventing framework and what each event done. Each event meant something, and you added code when you wanted to change things.
NET world, you can almost think of it like the old page model where you would have page load events. Important: Understanding Dynamics AX is all about understanding your SEQUENCE of Events. Wait, but we didn’t tell it how to refresh? And what is all of this override method stuff and ds.executeQuery. What did we just do? Refreshed the data displaying in the grid whenever we change a value in the form. Be sure to save the code after you are finished typing in the code. Add this code, then compile and run your form. Right click the methods node, go to Override method à modified. Expand the control that we named DemoComboBox. Now, if you compile and run your form, you will notice that you choose a value and nothing happens. In the properties section, set the Name property to DemoComboBox. Users can also add new values if you give them that option. Note: Combobox’s are a control which allows us to display a list of values for users to choose from. Right-Click on (usr) and click New Control à ComboBox.Note: due to the mechanisms of grouping being heavily explained in the previous parts of this tutorial, I will skip the explanation here. Make sure that the Style property is set to DetailTitleContainer, and ViewEditMode is set to Edit. Then, rename the group to ExtraCustomFilterGroup. Right-click on the group and choose properties. Note: remember that you can use your mouse to drag and drop it or +. Move the Group control down to where it appears just below the (usr). Right-click on Design and choose New Control à Group.Expand the Designs node and open up Design. Open up the SimpleListDetailExample and expand the DemoListDetailForm. In fact, I’ve taught many people how to program. I love programming and enjoy teaching it. You will be using the same machine and demo project.Īlso Note: this is strictly an introduction to programming. Note: This tutorial assumes that you have done Parts 1, 2, 3, and 4 of this series. For example, I list the most important events for forms here. Just remember that you don’t have to memorize all of the events – just know the most important ones. Let’s demonstrate some coding here by adding a filter to our form. Still, if you are new, hopefully, this will give you an understanding of one of the most powerful features of this product – ease of development. Making things confusing is that some of the things that are called “methods” in Dynamics AX are called “events” in other programming languages. If there is anything that you should take away from this is that the key to understanding Dynamics AX development is to gain an understanding of the eventing framework.
Trust me, I wish that I would have had something like this when I first started. If you’ve gone through the previous 4 parts of this series, you now have an introduction to forms within Dynamics AX. Now, it is time to finish the project and get introduced to some dynamics AX coding.
