Disable a Column in JavaScript

I need to disable a column in the WebDataGrid based on a value in a DDL.  If the user selects CarbonCopy in the DDL, I check the BoundCheckBoxField for all the rows in the grid.  Then I need to disable the column because the user cannot uncheck these fields.  I have not been able to figure out how to get at the ReadOnly property for the column.  FYI - I cannot use the CellValueChanging event to cancel the eventArgs because I am setting the value in the same function.  Here is my code...can you help?   

 

 

 

 

 

 

 

 

if

 

 

((ddlSigningMethod.options(ddlSigningMethod.selectedIndex).value == 'CarbonCopy') ) {

 

 

var wdgDocuments = $find('<%= wdgDocuments.ClientID %>');

 

 

// Spin though the Document Grid, checking all the Selected checkboxes

 

 

for (var i = 0; i < wdgDocuments.get_rows().get_length(); i++) {

selectedDocument = wdgDocuments.get_rows().get_row(i).get_cellByColumnKey(

 

"HasSignerAssociatedWithDocument");

selectedDocument.set_value(

 

true);

}

 

 

// These do not work to help me disable the row

wdgDocuments.get_behaviors().get_editingCore().get_behaviors().get_cellEditing().get_columnSettingFromKey(

 

"HasSignerAssociatedWithDocument")

wdgDocuments.get_behaviors().get_editingCore().get_behaviors().get_cellEditing().get_columnSettings()

}
