error "'Graph' is a variable but used like a type" when trying to dynamically get a graph full name

Question

Hello Everyone,

I have a funtion that depending on what graph is calling it should do different stuff. I would like to pass the graph calling the function then compare it to some graphs and do what I need. Inside the function when I try to compare the input graph I get an error that "'Graph' is a variable but used like a type". Below is the code snippet. How can I make it work?

public static string TestFunction(PXGraph Graph)
{
    if (Graph == null) return null;

    if (typeof(Graph).FullName == typeof(APInvoiceEntry).FullName)
    {
        // Do stuff here
    }

    if (typeof(Graph).FullName == typeof(ChangeOrderEntry).FullName)
    {
        // Do stuff here
    }

    // and so on for some more graphs

    return null;
}

I can get the graph FullName from the caller and pass to the function but I prefer not.

@aaghaei Try the following code:

public virtual void UpdateFSCacheInAPDoc(PXGraph graphHelper)
        {
            if (graphHelper is AppointmentEntry)
            {
                var appGraph = (AppointmentEntry)graphHelper;
                ...
            }
            else if (graphHelper is ServiceOrderEntry)
            {
                var soGraph = (ServiceOrderEntry)graphHelper;
                ...
            }
        }

It’s an actual method from SM_APInvoiceEntry extension.

Hi @aaghaeiIf we use the ScreenUtils, will get all graph informationbased on the screenID.We can get the screenID based on the accessinfo(Base.Accessinfo.ScreenID)Please try like below.Add name space PX.API and PX.MetaDataif (ScreenUtils.ScreenInfo.TryGet("AR301000").GraphName == typeof(APInvoiceEntry).FullName)      {        // Do stuff here      }Hope this will help you :)
