Hello,

I have a simple form with one text field binded to dataset.

for some reason when I call DA.UPDATE(DS) it's not working. I am using
stored procedures that are tested and working.


Thank you in advance :)

Here's the code:


Public Class frmTest

Inherits DevExpress.XtraEditors.XtraForm

#Region " Windows Form Designer generated code "

Public Sub New()

MyBase.New()

'This call is required by the Windows Form Designer.

InitializeComponent()

'Add any initialization after the InitializeComponent() call

End Sub

'Form overrides dispose to clean up the component list.

Protected Overloads Overrides Sub Dispose(ByVal disposing As Boolean)

If disposing Then

If Not (components Is Nothing) Then

components.Dispose()

End If

End If

MyBase.Dispose(disposing)

End Sub

Have you verified that there are Changes in the DataSet with
DataSet.HasChanges()? If not, then there's nothing to update. Tell me if
this is true or not and we'll take it from there.

It says "False"

Isn't it supposed to change to True once I change the Text inside firstname
control. It is bound to dataset.datatable.

Thanks

You need to call EndCurrentEdit. If this says false, then there are no
changes for the adapter to send back, so unfortunately you can call update
all year and nothing will happen. Call EndCurrentEdit and that should do it
for you.

However, when I try
msgbx.Show(DsTest1.NewSelectCommand.Rows(0).Item("firstname").ToString)

it does show changed value inside the textbox.

I don't know why it won't transfer it to database.



Vlado Jasovic (excelleinc.com) said:
It says "False"

Isn't it supposed to change to True once I change the Text inside
firstname control. It is bound to dataset.datatable.

Thanks
