[RESOLVED] [2008] Datagridview Help

I have the code for a datagridview style but for some reason when I run it, nothing shows up. I know the SQL is correct because I've debugged and gotten the SQL statement and executed it in Access and it does return values.

Please tell me what I am doing wrong...

Code:

---

Public Sub FillProdWellData()
        DataGridView1.Visible = False
        dgWellData.BringToFront()
        dgWellData.Visible = True

        Dim cmdFillProd As New OleDbCommand
        Dim refNum As Integer

        dsWellData.Clear()

        'the sql statement that retrieves the data from the database in table Param_Prod
        cmdFillProd.CommandText = "SELECT Distinct API, StartDate, EndDate, Reservoir, " _
                    & "InitialRate, FinalRate, DeclineRate, DeclineType, HypFactor, " _
                    & "GasOilRatio, ExtendDate, GasOil, ConstFlVol, InitialWater FROM Param_Prod " _
                    & "Where Reservoir = '" & Resvr & "' " _
                    & "AND TemplateName = '" & PrmName & "'"

        'the following tells the adapter what the select command is, sets the connection for the cmd and fills the
        'dataset with the data returned from the sql statement
        daWellData.SelectCommand = cmdFillProd
        cmdFillProd.Connection = gConn
        Try
            daWellData.Fill(dsWellData, "Param_Prod")
        Catch ex As Exception
            MessageBox.Show(ex.Message)
        End Try


        'tells dcDelete (a data column) that is is the boolean or checkbox.
        dcDelete.DataType = System.Type.GetType("System.Boolean")
        dcDelete.DefaultValue = False
        dcDelete.AllowDBNull = False
        dcDelete.ColumnName = "Delete"
        dcDelete.ReadOnly = False

        'it should only add the column once not constantly
        refNum += 1
        If refNum = 1 Then

In the FillProdWellData method, you have DataGridView1.Visible = False.

In the DisplayProdDGV method, you have DataGridView1.Visible = True commented out.

Is the problem that the datagrid is invisible?

No, the dgv is there but just empty with no data or header text. I fixed what you pointed out though, thx.

Ooops, you were right. That was the problem. But now, I have another question, when you look at the dgv, it has the columns API and Delete twice. Could you help me with that please?

Colums API and Delete are being added more than once

Your code

Code:

---

Public Sub FillProdWellData()
        DataGridView1.Visible = False
        dgWellData.BringToFront()
        dgWellData.Visible = True

        Dim cmdFillProd As New OleDbCommand
        Dim refNum As Integer

---

will reset refNum to zero each time you come into the sub. so the check

Code:

---

'it should only add the column once not constantly
        refNum += 1
        If refNum = 1 Then
            dsWellData.Tables("Param_Prod").Columns.Add(dcDelete)
        End If

---

will never work. In fact each time you access the dgv these colums will be added. Probly not the best thing to do but why not make RefNum a public variable or check your column adds in some other way?

Hope this helps.

Thank you for your suggestions. I will try them out.

I mad refNum public but it still adds the rows twice. I changed a couple more columns to a different type and it adds another duplicate row. Anybody know how to fix this?

How about this

Code:

---

cmdFillProd.CommandText = "SELECT Distinct API, StartDate, EndDate, Reservoir, " _
                    & "InitialRate, FinalRate, DeclineRate, DeclineType, HypFactor, " _
                    & "GasOilRatio, ExtendDate, GasOil, ConstFlVol, InitialWater , "" as API, "" as Deleted FROM Param_Prod " _
                    & "Where Reservoir = '" & Resvr & "' " _
                    & "AND TemplateName = '" & PrmName & "'"

---

This will add the extra 2 columns you need. You will not need to worry about adding them manually as they will be added by the SQL.

hope this is more helpful :)

I deleted the code adding the columns but it still adds the columns more than once. But only the ones that I have changed the column type.

        'DataGridView1.Visible = False
