ASPxClientEdit.ValueChanged Event

Fires when the control accepts the new value entered by a user.


ValueChanged: ASPxClientEvent<ASPxClientProcessingModeEventHandler<ASPxClientEdit>>

Event Data

The ValueChanged event's data class is ASPxClientProcessingModeEventArgs. The following properties provide information specific to this event:

Property Description
processOnServer Specifies whether or not to process the event on the server.


The control raises the ValueChanged event after it accepts the value entered by a user. To accept the new value, a user can press Enter, or defocus the value field (press Tab, or click another page area).

To react to any key press, handle the KeyUp event.

The event’s processOnServer argument property specifies whether to finally process the event on the server and fire the ASPxEdit.ValueChanged event or completely handle the ValueChanged event on the client-side.

<dx:ASPxComboBox ID="ASPxComboBox1" runat="server" AutoPostBack="true" ClientInstanceName="comboBox">
        <dx:ListEditItem Text="Item1" Value="10" />
        <dx:ListEditItem Text="Item2" Value="20" />
<dx:ASPxSpinEdit ID="ASPxSpinEdit1" runat="server" Number="0" MinValue="0" MaxValue="1"
    AutoPostBack="true" ClientInstanceName="spinEdit">
    <ClientSideEvents ValueChanged="OnSpinEditValueChanged" />
function OnSpinEditValueChanged(s, e) {

  • Built-in editors within the grid’s Filter Row do not raise the client-side ValueChanged, UserInput, and KeyDown events because these editors apply internal filter mechanisms.

  • When the ASPxGridLookup editor’s value changes, the editor sends a callback to the server to synchronize its value with the internal ASPxGridView control’s selection. Because of this, the server-side ASPxEdit.ValueChanged event fires before the client-side ValueChanged event.
