How to add Filter functionality to Display method in dynamics AXAPTA

Hi Friends,

Normally filters will work only in table fields but we can't do filters to display method.

This below code will work for filters to display method also.

Step 1:

Go to the form design right click on particular control properties Auto Declaration No to Yes.

Step 2:

Override the context() method on the display method .

public void context()

{

    int             selectedMenu;

    formrun         fr;

    Args            ag;

    Name            strtext;

    querybuilddataSource qb1;

    queryrun    qr;

    query       q;

    PopupMenu menu = new PopupMenu(element.hWnd());

    int a = menu.insertItem('Filter By Field');

    int b = menu.insertItem('Filter By Selection');

    int c = menu.insertItem('Remove Filter');

    ;

q   = ItemControl_ds.query();

qb1 = q.dataSourceTable(tablenum(ItemControl));

qb1 = qb1.addDataSource(TableNum(SalesTable));

qb1.addLink(FieldNum(ItemControl,PO),FieldNum(SalesTable,PurchOrderFormNum));  

selectedMenu = menu.draw();

    switch (selectedMenu)

    {

    case -1: //Filter by field

            break;

    case a:

            ag = new args('SysformSearch');

            fr = new formrun(ag);

            fr.run();

            fr.wait();

//Reading User entered value for filter process

            strtext = fr.design().controlName('FindEdit').valueStr();

            if(strtext)

            {

//Creating a query for filter

                

                qb1.addRange(FieldNum(SalesTable,SearchName)).value(strtext);

                ItemControl_ds.query(Q);

                ItemControl_ds.executeQuery();

            }

            break;

    case b:                                      // Filter By Selection

           

            qb1.addRange(FieldNum(SalesTable,SearchName)).value(ProjName.valueStr());

            ItemControl_ds.query(Q);

            ItemControl_ds.executeQuery();

            break;

    case c :                                      // Remove Filter

            q   = new Query();

            qb1 = q.addDataSource(tablenum(ItemControl));

            qb1.clearLinks();

            qb1.clearRanges();

            ItemControl_ds.query(Q);

            ItemControl_ds.removeFilter();

            break;

    Default:

            break;

    }

}

After adding the above code we are getting menus like

Avoid warning message for "Empty compound statement" in AXAPTA

How to  avoid warning message like "Empty compound statement" in AXAPTA

As:
Simply call the below method inside your while loop or catch block to avoid best practice error

Call exceptionTextFallThrough(); in the block. It does nothing, it's there just to say that you're intentionally not doing anything there (and to satisfy compiler).
