Sparse in set to true (default). The problem is, what my combo contains only codes starting with MISC, and the table has other codes. So, what it does: it selects the whole column content and shows nothing, until I leave this column.

I'm thinking, may be I should make it disable in case of not-MISC and I'm also thinking about playing with DynamicCurrentControl. In other words, I will use combo for MISC codes and ReadOnly textbox for non MISC.
