hi i have these codes:
Dim dt As New DataTable
                        ' Create four typed columns in the DataTable.
                        dt.Columns.Add("ConflictingPaper", GetType(String))
                        dt.Columns.Add("Numberofstudents", GetType(Integer))
                        dt.Columns.Add("AdminNo", GetType(String))
                        Dim query1 = (From a In dt3 Group CStr(a.Field(Of Integer)("PaperNo")) By AdminNo = (a.Field(Of String)("AdminNo")) Into Group Select dt.LoadDataRow(New Object() {String.Join(":", Group.ToArray()), Group.Count(), AdminNo}, False)).ToList().Count()
                        DataGridView3.AutoGenerateColumns = True
                        Me.DataGridView3.DataSource = dt
aiming to populate:

Conflictinglist    numofstudents   adminno
12:26              2               111411H

Use a debugger to see where the problem is. That will narrow down the issue.
