Tab

ASPxTextEdit.TextChanged Event

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

Namespace: DevExpress.Web

Assembly: DevExpress.Web.v24.1.dll

NuGet Package: DevExpress.Web

Declaration

public event EventHandler TextChanged

Event Data

The TextChanged event's data class is EventArgs.

Remarks

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

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

  • Set the AutoPostBack property to true.
  • In the client-side TextChanged 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 TextChanged event.
<dx:ASPxComboBox ID="ASPxComboBox1" runat="server" AutoPostBack="true" ClientInstanceName="combo"
    OnTextChanged="ASPxComboBox1_TextChanged">
    <Items>
        <dx:ListEditItem Text="Item1" Value="1" />
        <dx:ListEditItem Text="Item2" Value="2" />
    </Items>
</dx:ASPxComboBox>

<dx:ASPxSpinEdit ID="ASPxSpinEdit1" runat="server" Number="0"
    MinValue="0" MaxValue="1">
</dx:ASPxSpinEdit>
protected void ASPxComboBox1_TextChanged(object sender, EventArgs e) {
    ASPxSpinEdit1.Value = ASPxComboBox1.SelectedIndex;
}

ASPxGridLookup Limitation

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