Question

TableAdapter Won't Update

Asked by: tlchavet

Hi,

I added a datasource to my project and in turn it added a bindingnavigator, bindingsource and table adapter to my form.  This all seems to work fine; however, when I hit save on the bindingnavigator I get the following error:

Update requires a valid UpdateCommand when passed DataRow collection with modified rows.

The code, generated by Visual Studio when I added the data source, is:

        Me.Validate()
        Me.BOM_ENTRYBindingSource.EndEdit()
        Me.BOM_ENTRYTableAdapter.Update(Me.DsBOM_ENTRY.BOM_ENTRY)

All of the posts I have found refer to adding additional code before the update.  Because the code was generated by VS, I didn't want to mess something up be changing it.  Any ideas?

Try to do this way:

Dim cb As New SqlCommandBuilder(BOM_ENTRYTableAdapter)
Me.BOM_ENTRYTableAdapter.Update(Me.DsBOM_ENTRY.BOM_ENTRY)

The variable gets dimmed but not used?

 

by: tlchavetPosted on 2008-07-26 at 18:12:06ID: 22096840

It errors out because by tableadapter is not a sqldataadapter.

 

by: jpaulinoPosted on 2008-07-26 at 18:14:22ID: 22096845

Have you tried ?

It build the transact commands to the datadapter.

I am using a tableadapter control and datasource.  I would like to get it working as designed.  The link you are referring to would require a total rewrite.  There must be a way to update using the tools provided by Visual Studio.

 

by: jpaulinoPosted on 2008-07-26 at 18:22:19ID: 22096862

Do you have any master key on the table you're using ? It's an requirement.

 

by: tlchavetPosted on 2008-07-26 at 18:36:30ID: 22096892

Yes, I do.

 

by: tlchavetPosted on 2008-07-26 at 18:42:08ID: 22096902

I assume that it recognizes the key from the SQL Server or do I need to specify somewhere on the Visual Studio side what the master key is?

>> I assume that it recognizes the key from the SQL Server or do I need to specify somewhere on the Visual Studio side what the master key is?

Yes.

Try one more thing: goto the dataset you are using and right click on the table and choose configure. Then in the advanced option check the the "Generate Insert, Update and Delete statements" are checked.

 

by: tlchavetPosted on 2008-07-26 at 19:58:30ID: 22097023

It is checked.

 

by: jpaulinoPosted on 2008-07-27 at 02:42:54ID: 22097849

Make shure that in the dataset your primary key is ok.

It's working fine for me but it could be missing something.

 

by: SanclerPosted on 2008-07-27 at 03:32:01ID: 22097919

Are you using joined tables in your SELECT command?

Roger

 

by: tlchavetPosted on 2008-07-27 at 06:32:29ID: 22098440

I have double-checked the primary key.  And there are no joined tables in my select.  One simple table.

 

by: margajet24Posted on 2008-07-27 at 07:12:48ID: 22098533

ds               - DataSet
tablename  - Name of the table that needs to be updated

have you tried :

Me.BOM_ENTRYTableAdapter.Update(ds,tablename)

In the code you show in your first post, right click on the word Update in BOM_ENTRYTableAdapter.Update and then select "Go To Definition".  That should take you to something like this

>>
        <System.Diagnostics.DebuggerNonUserCodeAttribute(),  _
         System.ComponentModel.Design.HelpKeywordAttribute("vs.data.TableAdapter")>  _
        Public Overloads Overridable Function Update(ByVal dataTable As dsMainCust.MainCustDataTable) As Integer
            Return Me.Adapter.Update(dataTable)
        End Function
<<

In that, right click on the word Adapter and again select "Go To Definition".  That should take you to something like this

>>
        <System.Diagnostics.DebuggerNonUserCodeAttribute()>  _
        Private ReadOnly Property Adapter() As System.Data.SqlClient.SqlDataAdapter 'or may be OleDb or even ODBC
            Get
                If (Me._adapter Is Nothing) Then
                    Me.InitAdapter
                End If
                Return Me._adapter
            End Get
        End Property
<<

In that, right click on InitAdapter and again select "Go To Definition".  In the code that then appears, is there a line starting like this

>>
            Me._adapter.UpdateCommand.CommandText = 'followed by a string, in double quotes
<<

Once we know that, we'll have a better idea of where to look for the problem.

Roger

Sorry for the long delay - I was travelling today.

When I click on go to definition from Update in:

Me.BOM_ENTRYTableAdapter.Update(Me.DsBOM_ENTRY.BOM_ENTRY)

I get:

        <Global.System.Diagnostics.DebuggerNonUserCodeAttribute(),  _
         Global.System.ComponentModel.Design.HelpKeywordAttribute("vs.data.TableAdapter")>  _
        Public Overloads Overridable Function Update(ByVal dataTable As dsBOM_ENTRY.BOM_ENTRYDataTable) As Integer
            Return Me.Adapter.Update(dataTable)
        End Function

From the word adapter I get:

        <Global.System.Diagnostics.DebuggerNonUserCodeAttribute()>  _
        Private ReadOnly Property Adapter() As Global.System.Data.SqlClient.SqlDataAdapter
            Get
                If (Me._adapter Is Nothing) Then
                    Me.InitAdapter
                End If
                Return Me._adapter
            End Get
        End Property

I think we have gotten to the issue.  I don't have the line Me._adapter.UpdateCommand.CommandText .

 

by: tlchavetPosted on 2008-07-27 at 18:15:17ID: 22100234

I added the missing update rows based on another post I found and I am still getting the error.  When I went back and looked in the InitAdapter my added lines had disappeared.

 

by: tlchavetPosted on 2008-07-27 at 18:33:33ID: 22100281

For whatever reason, the lines stayed in the second time and the error is resolved.  Thanks for everyone's help.
