For PrintKeys you can get to the script that has it in one of two ways: edit script of behavior of behavior of selobj() edit script of stack "RevDataGridLibraryBehaviorsDataGridButtonBehavior" This is the PrintKeys handler: ``` command PrintKeys pArray if pArray is not an array then put sDataArray into pArray put _PrintKeys(pArray) end PrintKeys ``` And here is the _PrintKeys() function: ``` private function _PrintKeys @pArray, pDimension if pDimension is empty then put 0 into pDimension local theKeys, theText, theTempArray put the keys of pArray into theKeys sort theKeys numeric repeat for each line theKey in theKeys if pArray[theKey] is an array then put _printCharXTimes(space, pDimension * 5) & theKey & cr after theText put pArray[theKey] into theTempArray put _PrintKeys(theTempArray, pDimension + 1) after theText else put _printCharXTimes(space, pDimension * 5) & theKey & ":" && "`" & pArray[theKey] & "`" & cr after theText end if end repeat return theText end _PrintKeys ``` As you can see, PrintKeys prints off every key and value in the sDataArray array. sDataArray contains the array that you, the developer, assigned to the DataGrid using a property such as dgData or dgText. PrintKeys doesn't take into account the columns you've created in your DataGrid. That is a separate property. So my guess is that you are populating the DataGrid with data that only has 10 columns.
