Hi Experts,
I have a DataGrieView control in my VB.Net application which I load bind to a tableadapter programmatically.
I am able to update existing records from the datagridview control to the underlying database, but I am not able to insert\add records from the datagridview control to the database.

What am I doing wrong?  How can I fix this?


Below, I have added my code, and also the error message I get when I try to add the record to the datagridview:

Is there a way to programmatically add the ProviderMasterID, when I click on the Drop Down combobox?

Thank you very much in advance,
mrotor

Ark,
You were close, but I kept getting the error below:

Error:
Error i was getting when trying to add a row
I fixed it by adding a line of code and modifying your procedure a little (see code below):
Reference to were I got the additional line of code from:

Link to where I got the additional line of code from.

    Private Sub TblProviderBindingSource_AddingNew(sender As Object, e As System.ComponentModel.AddingNewEventArgs) Handles TblProviderBindingSource.AddingNew
	Dim bindingSource As BindingSource = CType(sender, BindingSource)	' Added Code
        Dim dv As DataView = TryCast(bindingSource.List, DataView)	                'Modified Code
        Dim rv As DataRowView = dv.AddNew()

        rv("LkLanguageId") = 12345
        e.NewObject = rv
        bindingSource.MoveLast()					                                                  'Modified Code
