Rowinserting And Rowinserted Difference In Acumatica

RowInserting and RowInserted difference in Acumatica

Hello everybody,

now I want to share with you difference between RowInserting and RowInserted events.

The RowInserting event happens before the new data record is actually inserted into the cache but after all field events happen for this data record. The RowInserted event happens after the actual insertion. If you change the data fields of the data record that you insert in a RowInserting event handler, no field events will be raised for these data fields. You use the RowInserted event to do something after a data record is inserted into the cache. For example, you can use a RowInserted event handler of the master data record to add a default detail data record.

Sample of RowInserting:

protected virtual void APAdjust_RowInserting(PXCache sender, PXRowInsertingEventArgs e)

{

.................. 

}

Sample of RowInserted

protected virtual void APAdjust_RowInserted(PXCache sender, PXRowInsertedEventArgs e)

{

.................. 

}

The main purpose of RowInserted IMHO is to add default details to data record

The Structure Of A Strategy Program In Lua

The Structure of a Strategy Program in LUA

Hi all,

I continue investiaging another area of knowledge of humankind, which is FXCM trading Station.

So, if you need to write strategy, you'll need following methods to be defined in your strategy: 

  1. Init()
  2. Prepare(nameOnly)
  3. Update()
  4. ReleaseInstance()
  5. AsyncOperationFinished(cookie, successful, message, message1, message2)
  6. CheckParameters(parameters)
  7. ChangeParameters()

Now little bit details:

The Init() function of the strategy is called once, when the host application has just loaded the strategy into the memory. In this function the strategy must create profile. Profile is the information which is required for creation of the strategy: strategy name and description and parameters.

When the function is being executed, there is a global variable called strategy. You must use the table kept in this variable to provide all necessary information.

Note: Values of any global variables, which are defined in the Init() function will not be available in the other strategies functions. Because the user can apply multiple instance of the same strategy at the same time, the new instance of the strategy is created every time when the user applies the strategy.

Prepare function is called every time when the user applies the strategy. At this moment, a copy of the strategy code is created. This copy is called strategy instance. At one moment, there can be as many strategy instances as many times the strategy is applied.

In this function you must:

  • Prepare all common data for further work of the strategy logic.

When the function is being executed, there is a global variable called instance. You must use this to access to the instrument and parameters data.

Parameter nameOnly indicates whether this function was called just for creating instance's name.

Important: strategy instance is always created in a new context. The Init() function is not called for an instance, so there is no way to pass data from the Init() function to the Prepare() function.

Update is a most important function in the strategy. The update function is called every time when a new bid or ask price appears on the instrument to which the strategy is attached.

Use the terminal table to get access to the trading application functions.

Release function is optional, you can omit it in your strategy.

In case this function exists, it is called before the strategy instance is destroyed. You can use this function to dispose objects created in the Prepare function.

Other functions will be described in another post

How To Add Buttons Refresh Add Row Delete Row Fit To Screen In Grid Of Acumatica

How to add buttons Refresh Add Row, Delete Row, Fit To Screen in Grid of Acumatica

Hello everybody,

Imagine that you crated in your page Grid, and when opened it at page can't notice buttons Refresh Add Row, Delete Row, Fit To Screen in Grid. I believe it can be puzzling how to add those buttons to screen as it was for me at once.  Add to your grid following line:

 SkinID="Details"

For example it can look like this:

<px:PXGrid ID="PXGrid1" runat="server" DataSourceID="ds" TabIndex="-8036" AdjustPageSize="Auto" AllowPaging="True" Height="200px" Width="100%" SkinID="Details" KeepPosition="True" MatrixMode="True"  SyncPosition="True">

If you add those attributes, you'll see those buttons.

Acumatica Epic Failed Or Captions At Page Not Appear

Acumatica epic failed or captions at page not appear

Hello everybody.

I want to share with whole world a story. In the begining of this month I created web form. Added there some controls. Today I wanted to add one another control, and after my addition miracously controls at page disappeared. I was surprised, looked for ways to solve problem, and after wasted hours I decided to remove and add control again. Try to imagine my shock, when caption of DAC appeared back on page!!!!. So next time if caption disappears just remove and add control at "Page Layout" and it maybe will appear. I have no comments, just plenty of negative emotions.

Pxdefault Pxparent In Acumatica

PXDefault PXParent in Acumatica

Hello everybody,

today just quick fact. In master-detail DAC and Graph there are used attributes PXDBDefault and PXParent. For me it was interesting to know, that PXDBDefault is intended for initializing values and PXParent is intended for cascade deleting of rows.
