Hierarchical grid filtering by value in the detail table

[Vladimir]

Hi,

I have a question about the following scenario:

I have a hierarchical grid which contains products. Every product has a detail table (the inner grid) with the countries where this product is being sold. Each row in the detailed table represents a different country.

I would like to have a filter which filters by country on top level, meaning that I would set for example a value "France" in that filter and in the grid I would get only the products that are being sold in France (meaning that in their detailed tables they have a row for France).

What approach would you recommend in order to achieve this behavior?

Thanks.

Hello Vladimir,

The solution may vary depending on your datasource. For example, if you use SqlDataSource, you could filter the data in the details tables directly, using a WHERE clause and a control parameter(s) tied to an external dropdown.

I hope this helps.

Hi Daniel,

thanks for your reply.

May be I haven't expressed myself clearly enough. I don't want to filter the details table, I want to filter the master table according to the rows in the details table.

So in the master table I have rows  with products. And for every product there is one details table with countries. I want to filter the master table so that it lists only products that have in their details table a country with certain name.

If I have this structure:

1. Product 1: Fanta
              1. France
              2. Italy
              3. Gemrany

2. Product 2: Sprite
              1. Spain
              2. France

I want to have a filter with the countries, and when I put there "Spain", in the master grid I would like to get only one row ("Product 2: Sprite") and it's details table shouldn't be filtered (so it will have two rows - for Spain and for France).

Thanks.

Hello Vladimir,

Please check the attached demo and let me know whether it is suitable for your scenario. You can find a detached DB (SQL 2005) inside the archive.
