Select * from Produto where code_product = textbox_code_product

In Portuguese

Eu preciso do valor sysProjetoBO1.prj_nrow na Value member do  sysProjetoEquipamentoBO  da propriedade PopulationDataSourceSettings. Como eu faço isso ?

I noticed you have this code:

But, your FillByProjetoEquipamentoGL(Int32) is expecting an Integer and the prj_cod.Text is string, so you have to make sure the value of the prj_cod.Text is an Integer, so you need to convert it using cint() or the equivalent C## function.
