Client side javascript - get grid selected row values

[Bernie]

I am trying to set some data elements on the screen based on what row was selected in a grid. So basically I want to get the grid column values for the selected row when onrowclick event is triggered. I then want to place these into some other fields to do updating. This is more of a test process just to know I am able to move or condition data from what has been selected in the grid and put it somewhere else.

Anyway, I have the following in the onrowclick event and it fails when I select the row with error "Cannot read property 'grid' of null".

var value = getObj("gridParts").grid.getCellValue(row, 0);
changeElementValue("getpart", value);

My grid is labeled gridParts and the output field on the screen is getpart.

Just a quick follow up on this so far. I was able to get it to work. I changed it to the following:
var value = getObj("Grid1").grid.getCellValue(rowNumber, 1);
changeElementValue("TextBox1", value);

I had to set it to the actual id of the element instead of the named value.
