i have an editable DataGrid, something like:
<mx:Datagrid editable="true" dataProvider="{arrayListPreferences}" id="preferencesGrid">
<mx:columns>
<mx:DataGridColumn header="col1" dataField="preference" editable="false"/>
<mx:DataGridColumn header="col2" dataField="value" editable="true"/>
</mx:columns>
</mx:Datagrid>
When the user edits the data there's a button that he clicks and calls a function that saves the data to a database, and in this function i have to validate the data before sending it. I want to use simple validators (NumberValidator, StringValidator, etc) but i don't know how to set the source of this validators to the specified rows in the second column.
<mx:NumberValidator source="{preferencesGrid.selectedItem}" property="value"
integerError="Enter Integer value"
minValue="18" maxValue="50" domain="int"
trigger="{saveButton}" triggerEvent="click"
valid="saveData();"/>
Set the property
of validator to the dataField
of the desired column.
