ASPxEdit.ValueChanged Event

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

Namespace: DevExpress.Web

Assembly: DevExpress.Web.v23.2.dll

NuGet Package: DevExpress.Web

Declaration

C#

public event EventHandler ValueChanged

VB.NET

Public Event ValueChanged As EventHandler

Event Data

The ValueChanged event's data class is EventArgs.

Remarks

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.

ASPX

<dx:ASPxComboBox ID="ASPxComboBox1" runat="server">
    <Items>
        <dx:ListEditItem Text="Item1" Value="10" />
        <dx:ListEditItem Text="Item2" Value="20" />
    </Items>
</dx:ASPxComboBox>

<dx:ASPxSpinEdit ID="ASPxSpinEdit1" runat="server" OnValueChanged="ASPxSpinEdit1_ValueChanged"
    Number="0" MinValue="0" MaxValue="1" AutoPostBack="true">
</dx:ASPxSpinEdit>

C#

protected void ASPxSpinEdit1_ValueChanged(object sender, EventArgs e) {
    var spinEdit = sender as ASPxSpinEdit;
    ASPxComboBox1.SelectedIndex = Convert.ToInt32(spinEdit.Value);
}

VB.NET

Protected Sub ASPxSpinEdit1_ValueChanged(ByVal sender As Object, ByVal e As EventArgs)
    Dim spinEdit = TryCast(sender, ASPxSpinEdit)
    ASPxComboBox1.SelectedIndex = Convert.ToInt32(spinEdit.Value)
End Sub

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.
