Question Problem with refreshing data in a datagridview

[Caraldur]

Hello everyone,

I am working on a MDI Application to track machine maintenance schedule and I have run into a problem with a datagridview.

When i launch my application (mdiMain) the load event triggers the opening of a form (frmTaskWork) with a datagridview. The load event of the frmTaskWork form calls the sub routine filldatagrid() which checks to see if the dataset (dsTasks) returned from my Task Class has any rows. If there are rows the datagrid is populated and if there are no rows the form is closed.

Here is the code for my Sub routine filldatagrid

Public Sub fillDatagrid()
        dsTasks.Clear()
        dsTasks = task.getCurrentTask()

        With bs
            .ResetBindings(False)
            .DataSource = dsTasks.Tables("TaskInfoList")
        End With

        If dsTasks.Tables("TaskInfoList").Rows.Count > 0 Then
            dgMaintenanceTask.DataSource = bs
            dgMaintenanceTask.Refresh()
            hideColumns()
        Else
            Me.Close()
        End If

        Console.WriteLine("")
        Console.WriteLine("------------Current Data in Dataset------------")
        For Each row As DataRow In dsTasks.Tables("TaskInfoList").Rows
            Try
                Console.WriteLine("Task Name: " & row.Item("TaskName") & " | " & _
                                  "Last Completed: " & row.Item("LastCompleted") & " | " & _
                                  "Machine: " & row.Item("EquipmentName"))
            Catch ex As Exception
                MsgBox(ex.Message.ToString())
            End Try
        Next
    End Sub

From this form (frmTaskWork) the user can click on a row in the datagridview which opens a form to allow the user to complete a work order for the selected maintenance item. The form (frmNewJob) that opens is populated with relevant data and allows the user to enter any notes. Once the submit button is click an array is filled with the data and passed to my Jobs class where it is inserted into my DB table and other tables are update. This part work as it should but the datagridview isn't being update with the new changes even though I am calling the filldatagrid sub routine.

Here is the the console output from before and after the insert.

-> After work order insert

As you can see from the output the dataset is being updated with the correct data but the datagridview isn't being updated. I'm not sure what the problem is or how to fix it.

I hope my explanation isn't too confusing and thanks in advance for any help.

I can't believe there isn't one person on this forum who can help me. Should I post my question on every sub-forum to get some kind of response?
