Load data into grid

[harlem98]

I'm having serious problems loading data into a grid, i've encountered a number of problems, which i´ve beem solving through different approachs, and now i dont found any issue, but i still cant load the data into the grid. The data is filtered in a external comboBox (rdpInvestigado r).

I use a n-layer architecture with ASP Object Data Source. i'm sharing the critical part of the code not to overextend the post.

After many tries, i have no ideia about what's wrong, does anyone familiar with this?
