ASPxEdit.ValueChanged Event

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

Assembly : DevExpress.Web.v25.2.dll

Declaration

C#
VB.NET

csharp

public event EventHandler ValueChanged

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

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#
VB.NET

csharp

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

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.
