Micronesia genexus grid conditions

How do I condition a filter in Genexus?

In GeneXus it is possible to condition both the filters (usually known as filter conditions or constraints) and the orders indicated in the objects or in the Grid controls, using the WHEN clause.

Does Genexus automatically load a grid?

Yes: Grids load automatically. This is the default value. GeneXus performs an automatic pagination if the Rows property of the grid has a value other than zero. The buttons inserted depend on the number of records to be shown and the number of lines of the grid.

Consider a Knowledge Base containing the following Transaction object s:

Why is there an 'implicit' for each grid line in Genexus?

Every grid line loaded is like the print executed in each iteration of the listing's For each command.

That's why we say there is an "implicit" For each.

What is a condition attribute in Genexus?

Attributes must belong to the Extended Table of the Base Table where the condition is applied. This property applies to the individual control for which it is defined. It must not be confused with the Conditions tab of the GeneXus object (whose aim is to apply filters to the whole object: form, all the Grids, etc.).

That's why we say there is an "implicit" For each. Later on we'll look at cases where this does not happen this way (grids without a base table).
