Try looking here.
BeaCosta is also a fountain of knowledge - assuming you're doing c# WPF

Please improve your question by being specific to the technology you're using, that will help getting better answers.
Also it may give you some good search phrases to put into google. And links to articles that may help your understanding.

I have a windows form application in C#, the code on form load is

daActivity.SelectCommand = new SqlCommand("SELECT * from DataActivity", cs);
dsActivity.Clear();
daActivity.Fill(dsActivity);

ActivityBS.DataSource = dsActivity.Tables[0];

dg.DataSource = ActivityBS;

this.dg.Sort(this.dg.Columns["DataInputID"], ListSortDirection.Descending);

where dg is datagridview that I have on my form, as you can see I fill dg from Sql Server, and it is sorted by first column in dg called DataInputID

this DataInputID is the same for multiple rows and I want to group them, being able to expand that group
I have looked on the google and found some solutions but was unable to implement them into my form, because most of those solutions are for asp.net

while I have simple basic windows form application that pulls data from Sql Server

Ok - put this code sample and explanation into your original question (using the improve question option) then you'll probably get some great answers.

I found this

Indication that it may be an uphill struggle..

Maybe have a look at this article:
