Filter dataset columns

[SPG]

Hi,

I need to be able to filter the columns that are visible through a dataset.
That is, I can have all columns in a dataset, but only some of them are
visible when filtered.

I know you can use rowfilter on a dataview. Is there anything like that I
can use?

Hi,
I think that you mean datatable columns, not dataset columns.

You cannot filter columns as you filter rows, you have to go with a
workaround, you can create a new table with the column structure you need,
then using the DataColumn.Expr ession you can make reference to the original
table. Please make sure to include a FK relationship between both tables,
having the temp table as the child end, then Expression can be like
Parent.Name

Then you need to fill the table and you can use this new table as a "view".

Cheers,
