Visual Basic

So in essence there is really no difference between the way Gregory and myself implemented this.

Happy Coding

Dim lobj As Object = Activator.CreateInstance(Type.GetType("DummyLib.clsTestingTheStateHandler,DummyLib"))

Dim lass As Reflection.Assembly = Reflection.Assembly.Load("DummyLib")
Dim ltype As Type = lass.GetType("DummyLib.clsTestingTheStateHandler")
Dim lmi As Reflection.MethodInfo = ltype.GetMethod("ThisIsTheHandler")
Dim lblnState As Boolean = DirectCast(lmi.Invoke(lobj, New Object() {phtParameters}), Boolean)

foreach (GridViewRow row in datagridView.Rows)
    {
        
        CheckBox cbYesOrNo = (CheckBox)row.FindControl("cbYesNo"); // your control name
              
        if (cbYesOrNo.Checked)
            {
		// Do something
	    }
        else
	    {
		// Do something
	    }                  
            
    }

dim dv as dataview

        ' MessageBox.Show(DateTimePicker1.Text)
        dv.RowFilter = "duedate = '" & DateTimePicker1.Text & "'"
    End Sub

Datagridview1.datasource = myDataview

dim myDataview as new dataview(myDataset.tables(0))
