How to handle events of programatically created tools in a loop - vb.net

Question

I am creating a form builder which creates multiple tabs and on each tab will place a DataGridView linked to a dataset in a dataset array:
For Each table As DataTable In datasetInput(i).Tables
If arr_tables(i)(j).Equals(table.TableName) Then
tablename = table.TableName
Dim grid As New DataGridView
grid.DataSource = table
grid.Name = j
grid.Location = place
grid.Size = New System.Drawing.Size(734, 150)
TabPage.TabPages(i).Controls.Add(grid)
End If
Next
Note that this loop is nested within another loop that handles each tab on the form. arr_tables is a jagged array which handles which tables from the dataset I want because I do not want to pull every datatable into a DGV.
Now what I need to do is format any cell that falls in the column of name "Equation". For all cells in the "Equation" column I want to be a drop down cell with a few different options. Secondly, how can I handle a cell click event? Say any cell that falls in the column name "Input" I want to provide a MessageBox.
Normally I would have no issue doing these things if the DataGridViews weren't created within a loop. But because they are they get lost within the code and I don't know how to reference them.
Thank you!

Try this:
Private Sub Form1_Load(sender As Object, e As EventArgs) Handles MyBase.Load
For Each table As DataTable In datasetInput(i).Tables
If arr_tables(i)(j).Equals(table.TableName) Then
tablename = table.TableName
Dim grid As New DataGridView
grid.DataSource = table
grid.Name = j
grid.Location = place
grid.Size = New System.Drawing.Size(734, 150)
TabPage.TabPages(i).Controls.Add(grid)
AddHandler grid.SelectionChanged, AddressOf grid_SelectionChanged
End If
Next
End Sub
Private Sub grid_SelectionChanged(sender As Object, e As EventArgs)
' your code
End Sub
