how to query a datatable used by grid in C#?

[Administrator]

Hi,

I have a datatable used as datasource of my databoundgrid. I need to query this table in the codes periodially to get the most current information. It is kind of like

select sum(quantity)
from table
group by company, region

the quantity, region adn company are all columns for this table and names of the columns. It is a easy job in sql but I did not find the proper syntax in C#.

Could anyone please provide some samples?
Thanks

Our GridDataBoundGrid displays whatever data is in the DataSource. So, if youwant to ''reload'' the data, then you need to reload whatever datasource you are using. This is completely independent fo our grid.

It sounds like you want to should use a SqlDataAdapter/SqlConnection to load a sql query into a DataTable. Then you would set this DataTable as the DataSource for the grid, and it would show your sql query results. In the 3.0.1.0 grid User Guide, check the DataBoundGrid Tutorial. It steps you through using the desiger to create a dataadapter that uses a sql query.
