Add button to the top toolbar on Case screen - acumatica

Question

I am trying to add a new toolbar button next to "TAKE CASE" in Case screen (CR306000). I have customize CRCaseMaint DAC but still the button is not appearing. Can anyone please suggest.

Answer 1

replicated this and issue and solution was PXAction should be public. In sample above its marked as private.
code as follows works:
public class CaseExtension : PXGraphExtension<CRCaseMaint>
{
public PXAction<CRCase> Change2;
[PXButton(CommitChanges=true)]
[PXUIField(DisplayName="Change Me")]
protected virtual void change2()
{
}
}

Answer 2

Here is another reason. In base graph there is code
public PXAction<CRCase> takeCase;
[PXUIField(DisplayName = "Take Case", MapEnableRights = PXCacheRights.Update, MapViewRights = PXCacheRights.Select)]
[PXButton]
public virtual IEnumerable TakeCase(PXAdapter adapter)
Acumatica itself has button TakeCase which blocks your button TakeCase. You need to understand, why you need another one button Take Case because Acumatica team already implemented it. Are you sure you want to replace it?

Answer 3

Following steps are needed for you:
1. Create class library (CL).
2. Reference in created CL dlls from Acumatica folder which start from PX.*
3. In CL add new class CRCaseMaintExt with member TakeCase like this:
public class CRCaseMaintExt : PXGraphExtension<CRCaseMaint>
{
private PXAction<CRCase> TakeCase2;
[PXButton]
[PXUIField(DisplayName = "Take Case")]
public virtual IEnumerable takeCase2(PXAdapter adapter)
{
//your custom code
return adapter.Get();
}
}
4. Take note, that case in TakeCase and takeCase matter. Also matters PXAction
5. Build CL
6. Add reference to CL to your Acumatica project.
