How to call a method when clicking button - acumatica

Question

Very unfamiliar with Acumatica, I am trying to make a button clickable that I configured on the Employee Time Card screen. I want it to call a method when clicked but I have been unsuccessful.
Here is my the screen. The button is labeled PUNCH CARD.
Made some changes:
When I click on the PUNCH CARD button I do see a POST back to the server: https://dev.domain.tld/db/(W(20))/pages/ep/ep305000.aspx?PopupPanel=Inline&HideScript=On&TimeCardCD=TC00000001
I think I should be seeing some exception response on the screen but I see nothing.
Here is the aspx code. I don't know what to put in the DependOnGrid attribute. I just copied what was on Yuri Zaletskyy's blog. Is this always set to this or is there something specific to the site / page I am working with? If so how do I determine what to put here?
<px:PXToolBarButton Text="Punch Card" Visible="True" DependOnGrid="grdJiraProjects">
<AutoCallBack Target="" Enabled="True" Command="punchCard">
<Behavior CommitChanges="True" /></AutoCallBack>
<PopupCommand>
<Behavior CommitChanges="True" />
</PopupCommand></px:PXToolBarButton>

DateTime dtClockIn = DateTime.Parse(rows.UsrPIXIClockIn.ToString());
DateTime dtClockOut = DateTime.Parse(rows.UsrPIXIClockOut.ToString());
double total = (dtClockOut - dtClockIn).TotalHours;
rows.UsrPIXITotalHours = (decimal) total;
}
}
}

One common catch that results in the button action event handler not being called is using the wrong DAC for the action generic type parameter.
Make sure the action generic type matches the graph primary DAC. In your case this would be EPTimeCard:
public PXAction<EPTimeCard> PunchCard;
Do you have a Graph Extension?
That's where you should put the action event handler for the button.
In your case TimeCardMaint is the graph of the employee time card screen:
using PX.Data;
using PX.Web.UI;
using System.Collections;
namespace PX.Objects.EP
{
public class TimeCardMaint_Extension : PXGraphExtension<TimeCardMaint>
{
public PXAction<EPTimeCard> PunchCard;
[PXButton]
[PXUIField(DisplayName = "Punch Card")]
public virtual IEnumerable punchCard(PXAdapter adapter)
{
// This is where you handle button click event
return adapter.Get();
}
}
}
There is something special about the button you added. It is located in a grid toolbar. It's often the case that you want grid toolbar actions to operate on the currently selected line. For that to work you need to declare the action in ASP file and set it's DependOnGrid property:
This is explained in more details here:

This link could help you too:

Once everything is setup you could then access the currently selected record in the grid from your action event handler like this:
[PXButton]
[PXUIField(DisplayName = "Punch Card")]
public virtual IEnumerable punchCard(PXAdapter adapter)
{
EPTimeCardDetail row = Base.Activities.Current as EPTimeCardDetail;
if (row != null)
{
// Presumably do some Punch Card action on selected row from Details tab Activities grid
}
return adapter.Get();
}
