    CAML query for Group by count and data

    Company Category Product Name
    Microsoft Developer Visual Studio
    Microsoft Consumer Windows
    Microsoft Enterprise SharePoint 2010
    Microsoft Mobile Windows 7
    Samsung Consumer Laptops
    Samsung Consumer Mobiles
    Samsung Consumer Tablet
    Google Consumer Search Engine

    The above is my SharePoint List, I want to group by company’s name and then count the number of rows for each grouped by data and also display only chunk of data that is grouped.

    Company – Microsoft – 4 count

    Microsoft Developer Visual Studio
    Microsoft Consumer Windows
    Microsoft Enterprise SharePoint 2010
    Microsoft Mobile Windows 7

    Company – Samsung – 3 count

    Samsung Consumer Laptops
    Samsung Consumer Mobiles
    Samsung Consumer Tablet

    Company – Google – 2 count

    My  Solution – using CAML query LINQ

    using (SPSite site = new SPSite(“http://server“))
    
    {
    
    SPWeb web = site.OpenWeb();
    
    SPList listCAMLQuery = web.Lists["listName"];
    
    SPQuery query = new SPQuery(); // query for all the items
    
    DataTable dt = listCAMLQuery.GetItems(query).GetDataTable(); // get datatable for all the list items
    
    if (dt != null && dt.Rows.Count > 0)
    
    {
    
    //Group the data
    
    var groupedList = from row in dt.AsEnumerable()
    
    group row by row.Field<string>(“Company”) into groupedTable
    
    // Company is the column name for groupby
    
    // string is the type of column
    
    orderby groupedTable.Key // key is the groupby column category value
    
    select new
    
    {
    
    Key = groupedTable.Key, // key is the groupby column category value
    
    companyCount = groupedTable.Count(), // count for columns in a groupby
    
    groupedRows = groupedTable.CopyToDataTable() // grouped data
    
    };
    
    // print result
    
    foreach (var items in groupedList)
    
    {
    
    int count = items.companyCount; // count for columns in a groupby category
    
    DataTable dt1 = items.groupedRows;
    
    gv.DataSource = dt1; //gridview
    
    gv.DataBind();
    
    }
    
    }
    
    }
    
    }
