ASPxEdit.ValueChanged Event

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

Namespace: DevExpress.Web

Assembly: DevExpress.Web.v22.2.dll

NuGet Package: DevExpress.Web


public event EventHandler ValueChanged

Event Data

The ValueChanged event's data class is EventArgs.


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 allow the editor to raise the server-side ValueChanged event, use one of the following options:

  • Set the AutoPostBack property to true.
  • In the client-side ValueChanged event handler, set the processOnServer argument property to true. In this case, the editor raises the client-side event and then raises the server-side ValueChanged event.
<dx:ASPxComboBox ID="ASPxComboBox1" runat="server">
        <dx:ListEditItem Text="Item1" Value="10" />
        <dx:ListEditItem Text="Item2" Value="20" />

<dx:ASPxSpinEdit ID="ASPxSpinEdit1" runat="server" OnValueChanged="ASPxSpinEdit1_ValueChanged"
    Number="0" MinValue="0" MaxValue="1" AutoPostBack="true">
protected void ASPxSpinEdit1_ValueChanged(object sender, EventArgs e) {
    var spinEdit = sender as ASPxSpinEdit;
    ASPxComboBox1.SelectedIndex = Convert.ToInt32(spinEdit.Value);

ASPxGridLookup Limitations

  • 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 ValueChanged event fires before the client-side ValueChanged event.
