ChildInputValue property

ChildInputValue property

(Windows only; GUI for .NET only)

Returns a Progress.Data.InputValue instance containing input values for all fields in the current row of the specified child temp-table displayed in the bound .NET control. Use the indexers in this instance to access the input value of a specific field in the row.

Use this property when the BindingSource object is bound to a ProDataSet object that contains child buffers.

Data type: Progress.Data.InputValue class

Access: PUBLIC Readable

Applies to: Progress.Data.BindingSource class
Syntax
ChildInputValue[ buffer-handle | buffer-name ] 
buffer-handle

A HANDLE variable that represents the handle to the child temp-table buffer whose input values you want to access.

buffer-name

A CHARACTER expression that evaluates to the name of the child temp-table buffer whose input values you want to access.

The following code fragment illustrates how to use this property:
DEFINE VARIABLE orderInpVals AS Progress.Data.InputValue NO-UNDO. 
DEFINE VARIABLE orderNum     AS INTEGER                  NO-UNDO. 
bufName = args:Row:Band:KEY. 
IF bufName EQ "ttOrder" THEN DO: 
  orderInpVals = myBindingSource:ChildInputValue[bufName]. 
  /* InputValue indexer is 0-based */ 
  orderNum = UNBOX( orderInpVals[0] ). 
  IF orderNum > 10000 THEN DO: 
    MESSAGE “You have reached max number of orders.” 
    ... 
  END. 
END.
