Dynamics CRM 2011: Rolling up subgrid totals to a form field

  • [アーティクル]

MSCRM does require a little bit of coding when we try to add form field values. A common scenario is the addition of two inputted field values to make a third calculated value. This is easily achieved by using the method "Xrm.Page.getAttribute('ATTRIBUTE NAME').

For example the following method, when invoked in a form's OnSave event will add two floating point fields "new_firstvalue" and "new_secondvalue" and set the value of the field "new_calculatedthirdvalue":

 

function calculateThirdValue ()

{

   var FirstValue = Xrm.Page.data.entity.attributes.get("new_firstvalue").getValue();

   var SecondValue = Xrm.Page.data.entity.attributes.get("new_secondvalue").getValue();

   varCalculatedThirdValue = parseFloat(FirstValue )+parseFloat(SecondValue);

   Xrm.Page.data.entity.attributes.get("new_calculatedthirdvalue").setValue(varCalculatedThirdValue);

}

Lately I needed to do something a little different. I wanted to roll up values from a subgrid view embedded in my form. So after a little experimentation, I came up with this method which can be re-used for different subgrid columns. So in my OnLoad even I invoke a method like this:

function calculateRolledUpTotals()

{

  //Calculate total of column 1

   var col1Total = aggregateGridFields('new_column1');

   Xrm.Page.getAttribute('new_column1total').setValue(parseInt(col1Total ));

   Xrm.Page.getAttribute('new_column1total').setSubmitMode('always'); ...

}

and this re-usueable method then totals the subgrid values for the column pass to is by name: 

function aggregateGridFields (columnName)

{

   var gridControl = document.getElementById('queryset').control;

   var ids= gridControl.get_allRecordIds();

   var aggCount=0;

   for(i = 0; i < ids.length; i++)

   {

var cellValue = gridControl.getCellValue(columnName,ids[i]);

      if (parseInt(cellValue))

   {

      aggCount+=parseInt(cellValue, 10);

   }

}

return aggCount;

}

    Only problem is this only calculates what's currently showing in the grid. How do we calculate ALL items, not just those on the current page?

    Hi, what does 'queryset' refer too? Is it the name of the entity your working on, or the name of the entity is sub grid refers too?
