Remarks

In batch edit mode, the grid allows a user to edit batches of grid data on multiple pages and send them to the server in a single request. To support this functionality, the grid keeps changes on callbacks when a user interacts with unsaved modified data (for instance, when a user navigates to another page within the grid or sorts data).

The enabled KeepChangesOnCallbacks property also allows the grid to display the Preview Changes button. When a user clicks this button, the grid shows only modified rows from all grid pages.

When the KeepChangesOnCallbacks property is disabled, the grid behaves as follows:

• Does not display the Preview Changes button.

• Shows the Confirmation dialog box on callbacks (the ShowConfirmOnLosingChanges property) to confirm user interactions with unsaved modified data.

  

  ASPX

  <dx:ASPxGridView ID="ASPxGridView1" runat="server" KeyFieldName="ProductID">
    <%--...--%>
    <SettingsEditing Mode="Batch">
        <BatchEditSettings EditMode="Cell" KeepChangesOnCallbacks="False"/>
    </SettingsEditing>
  </dx:ASPxGridView>
  

If the KeepChangesOnCallbacks property is set to Default, the control’s behavior is based on the DataControlBatchEditKeepChangesOnCallbacksDefaultValue property value.

C#

ASPxWebControl.BackwardCompatibility.DataControlBatchEditKeepChangesOnCallbacksDefaultValue = false;

VB.NET

ASPxWebControl.BackwardCompatibility.DataControlBatchEditKeepChangesOnCallbacksDefaultValue = False
