I have a datagrid that uses database "key" values as column names. The database holds details about the legal range of values that may be set in any column. So when the user enters a value in the datagrid I wish to have the entry validated against the range described in the database. The external (to the datagrid) validation routine requires the field key which the datagrid stores as a column name and the value the user has entered. The value being checked is returned if it is within the legal range otherwise a default value is returned.
I have written the following script which is placed in the datagrid group. While the script works I have a feeling that there might be a better/ more elegant way of calling the validation routine.
My script, comments please:
Code: Select all
On CloseFieldEditor pFieldEditor
//calls a validation routine on the Encode decode stack
// Extract the information needed to do the validation check
put the dgColumn of the target into tColumn -- tColumn is used as a search key in a data table
put the text of PFieldEditor into tValue -- Text the user entered in the cell
// Validate the entry
put ValidateEntry(tColumn,tValue) into tValidData -- returns with a valid value either the user entry or a default value
// Write data to the datagrid cell
set the text of pFieldEditor to tValidData -- write the text back to the cell
end CloseFieldEditor
