Hi team,

I wrote below code to enable or disable the buton.

class SalesInvoiceOrgActiveEventHandlers
{
    /// 
    /// to enable or disbale SalesInvoiceOriginal button based on setup in Cust parameter.
    /// 
    /// 
    /// 

    

    [FormDataSourceEventHandler(formDataSourceStr(CustInvoiceJournal, CustInvoiceJour), FormDataSourceEventType::Activated)]
    public static void CustInvoiceJour_OnActivated(FormDataSource sender, FormDataSourceEventArgs e)
    {
        #Define.SalesInvoiceOriginal('SalesInvoiceOriginal')
        CustInvoiceDuplicateTable_W     custInvoiceDuplicateTable_W;
        CustInvoiceJour                 custInvoiceJour = sender.cursor();
        FormRun                         element         = sender.formRun();
        FormControl                     SalesInvoiceOriginal    = element.design(0).controlName(#SalesInvoiceOriginal);
        FormDataSource                  custInvoiceJour_ds;
        CustParameters                  custParameters = CustParameters::find();

        // This condition is to added to control the SalesInvoiceOriginal button to get disable once the report got executed for 1st time
        // for the current record.
        if (custParameters.RestrictOrgPreview == NoYes::Yes && custInvoiceJour.OrgPreviewPrint == NoYes::Yes)
        {
            SalesInvoiceOriginal.enabled(false);
        }
        else
        {
            SalesInvoiceOriginal.enabled(true);
        }     
    }
    
}

The button is working fine for enabled or disbaled. Once I refreshed the form then only it work properly.

I am looking for enabled or disabled the button without refreshing the form. Kindly let me know what to do?

Please give me more shed on this.

thanks!

You can try 2 things.

First is to write code in active method for the form ds. Because coc is much faster and best in performance when compared to handler and handler only when that event happens

Second is to call ds.research(); and ds.refresh();

Hi,

Try calling FormDataSourceName_ds.research();

Thanks,

You cannot say COC is best in performance when compared to event handlers.

COC will be easy to use for coding when compared to event handlers but there is no difference between performance.

This is because you need to enable or disable the button based on condition if original print view of report is printed.

After clicking on print original the form datasource should be refreshed.

Before if condition please use sender.reread()

Sender.refresh()

Although never used sender directly but you can try it doesn't work then map formdatasource variable custInvoiceJour_ds and use it as custInvoiceJour_ds.reread() and then custInvoiceJour_ds.refresh

Hi Girish,

FormDataSourceName is not declared in our code. Is any format to declare that.

FormDatasource custInvoiceJour_ds = sender;

Use above line of code to declare it.

You need to call that after the if and else condition.

It should be like that.

if (custParameters.RestrictOrgPreview == NoYes::Yes && custInvoiceJour.OrgPreviewPrint == NoYes::Yes) { SalesInvoiceOriginal.enabled(false); } else { SalesInvoiceOriginal.enabled(true); } CustInvoiceJour_ds.reread(); CustInvoiceJour_ds.refresh();

Refresh should be after the if condition.

Thanks,
