Question : Datagridview row updating event

Hi,

I have a dropdownlist in the gridview.
When i edit and click the update button it does not seem to make any difference.
The row stays in the edit mode.
can you see and let me kow what is wrong with the code?

Thanks

Private Function getClassDD() As DataSet
Dim conn As New SqlConnection(myconn)
conn.Open()
Dim strquery As String = Nothing
strquery = "Select distinct(Class) from Production.Product"
Dim mycommand As New SqlCommand(strquery, conn)
Dim myadapter As New SqlDataAdapter(mycommand)
Dim ds As New DataSet
myadapter.Fill(ds)
conn.Close()
Return ds
End Function

Protected Sub GridView1_RowCancelingEdit(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewCancelEditEventArgs) Handles GridView1.RowCancelingEdit
GridView1.EditIndex = -1
GridView1.DataBind()
End Sub

Protected Sub GridView1_RowDataBound(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewRowEventArgs) Handles GridView1.RowDataBound
If e.Row.RowType = DataControlRowType.DataRow And (e.Row.RowState And DataControlRowState.Edit) > 0 Then
Dim dd_MyClass As DropDownList = DirectCast(e.Row.FindControl("dd_Class"), DropDownList)
dd_MyClass.DataSource = getClassDD()
dd_MyClass.DataTextField = "Class"
dd_MyClass.DataValueField = "Class"
dd_MyClass.DataBind()
End If
End Sub
Protected Sub GridView1_RowEditing(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewEditEventArgs) Handles GridView1.RowEditing
GridView1.EditIndex = e.NewEditIndex
GridView1.DataBind()
End Sub
Protected Sub GridView1_RowUpdating(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewUpdateEventArgs) Handles GridView1.RowUpdating
Dim dd_MyClass As DropDownList = DirectCast(GridView1.Rows(e.RowIndex).FindControl("dd_Class"), DropDownList)
Dim val As String = dd_MyClass.SelectedIndex
e.NewValues.Add("Class", val)
GridView1.DataBind()
End Sub

Answer : Datagridview row updating event

If you want to enter data from keyboard - you need a while loop, something like in the snippet.

Can't get why do you need sorting?
