Javascript method of accessing grid rows

[esdaled]

I am working with a grid which has a checkbox to select rows for subsequent processing. The user can check multiple rows.

I am trying to use some javaScript to display a count of the number of grid rows which have been selected.

I have tried using the following code associated with the checkbox's onChange event:

Code: Select all

	var nbrChecked = 0;
	var row = 1;
	while (getObj('SELEC.'+row)){
		if (getObj('SELEC.'+row).checked==true){
			nbrChecked++;
		}
  		row++;
  	}

	changeElementValue("selecCount", nbrChecked);

The code only works when the user is on page one. When on page two 'SELEC.1' is undefined.

Is there a way of accessing information on rows which have been sent to the browser but aren't on the current page? or do you have an alternate suggestion?

Is this grid a page at a time subfile or a load all?

A page at a time subfile.

Ok. So because this is a page at a time subfile, the only rows that exist at a given time are the ones displayed. Accessing elements off page just won't be possible.

Any way you could make this a load all subfile?

I should be able to. Thanks.

I have changed my grid to a load all subfile, but the code quoted previously now only works if row 1 is visible.

is the grid using the scroll bar or paging bar?

[esdaled]

scroll bar

Profound UI's grid renders only the records which are currently visible. So if they are not currently in view, the widgets are not rendered.

Of course the rendering framework does have the data for all records which were sent to the browser, but there is not currently an interface to this.
