DDSetChangedValue - cWebBaseDEO

Sets the Field_Changed_State of the DDO and field that is associated with this DEO

Type: Procedure

Parameters

Parameter Type Description
sValue String Value to set

Syntax

Procedure DDSetChangedValue String sValue

Call Example

Send DDSetChangedValue sValue

Description

Sets the Field_Changed_State of the DDO and field that is associated with this data entry object (DEO). This is used by cWebColumn's RequestColumnLookup method. Because the Data Dictionary's (DD's) value is set, this DEO will also be updated with the value. This is really just a helper function that lets you set a DD field value without having to get the Server, Data_File, Data_Field, etc.

Important

This is the recommended way of change the value of an data-bound web DEO during a web request. You should not use "WebSet psValue" or "WebSet pbChanged" to do this because those changes are not propagated to the DDO until the next server round trip (and maybe not even then). You should only "WebSet psValue" with non-data aware web DEO controls. If the DEO control has data-binding, use DDSetChangedValue.

For example:

// does a lookup style find for the passed column based on the value of the search text
// This is used when you are doing lookup/searches
Procedure RequestColumnLookup String sSearchText
    Send DDSetChangedValue sSearchText
    Send Request_Find GE
    If not Found Begin
        Send Request_Find LT
    End
End_Procedure
