Filtering a Grid with a Session Variable
How to filter the contents of a list based on the user's ID or another value.
Many applications need to filter the contents of a list based on the user's ID or another value. To do this you need to add some code to the Inside of the component override section of the page. Assume that the unmodified code of the grid component looks like this:
with tmpl componentName = "NewTask" end with
There may be a different variable name than tmpl, but it does not matter. Assume that:
the control that you want to filter is the second one in the component
the control name is Prop_Owner_Id
you have placed the filter value into a session variable named session.Unique_User
The following code would filter the contents of the drop down list.
with tmpl componentName = "NewTask" field_info.DropDownBox.Filter = "Prop_Owner_Id="+session.Unique_User end with
If you were going to filter the drop down list with a date value (e.g. session.last_logon_date ), you would use.
with tmpl componentName = "NewTask" field_info.DropDownBox.Filter = "Prop_Owner_Id="+s_quote(session.last_logon_date) end with
The same technique applies to dialog components.
