List View In Accumatica


Here I want to describe how to create such simple page like this:

For reading this manual father you need to know how to add page to sitemap in accumatica. If you need me to describe this process let me know, I assume it is not challenging process.

For staff like this you need ListView template and two other classes.

The first class is used to represent single view item in grid and second class intended for navigating in the db. 

Accumatica manual recomends the following location of those two classes:

1. Create separated project ( for example IG )

2. Inside of it create Folder with the name of pages folder ( for example Investigation )

3. Add reference to the dll PX.Data

4. Create class CountryMaint:

namespace IG.Investigation
    public class CountryMaint : PXGraph<CountryMaint>

5. Build class library and add reference to newly created project.

I got something similar to this ( just without red rectangle ):

For now we have manager of records but without representation of records itself. Let's do it with tool called Data access class generator. Switch back to the file IG301000.aspx choose design mode and for the typename choose IG.Investigation.CountryMaint. 

Press at generate class and in the window that will appear type Country.

Here is what I seen:

Press at "Generate" button and you'll see that class which can represent single record was created exactly in DAC folder.

Now if will have desire to open developed web page you'll notice 

Error #96: View  doesn't exist.

which means that we need to add something, that is called view. What it can be? Add to the class following line

public PXSelect<Country> Countries;

and Visible="true" and then try to open page again:

Error #96: View  doesn't exist.

Why? I went nuts tring to figure out, untill I watched in manual, which sad the next phrase: 

In the Properties window, set the following property for the grid:

• DataMember:Countries

But why it speak about non-mentioned DataMember as View ? I have no idea, but if you have share it.

So, let's set it and execute. Are you ready to see result?

If to put simly this warning means that you need to add method Save to the CountryMaint class. But why Accumatica doesn't show anything I have no idea.

Let's add it:

public class CountryMaint : PXGraph<CountryMaint>
        public PXSelect<Country> Countries;
        public PXSave<Country> Save;

and open the page:

Cool, isn't it? Button save is ready. 

Let's add some fields for displaying. It can be done at PXGrid, via Edit content layout link:

Then you just add fields CountryCD and description. I'll omit this process because IMHO it is not complicated. Execute page again and you'll see list of countries. Enjoy !!!!
