ASPxTextEdit.TextChanged Event

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

Namespace: DevExpress.Web

Assembly: DevExpress.Web.v23.2.dll

NuGet Package: DevExpress.Web

Declaration

C#

public event EventHandler TextChanged

VB.NET

Public Event TextChanged As EventHandler

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.

ASPX

<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>

C#

protected void ASPxComboBox1_TextChanged(object sender, EventArgs e) {
    ASPxSpinEdit1.Value = ASPxComboBox1.SelectedIndex;
}

VB.NET

Protected Sub ASPxComboBox1_TextChanged(ByVal sender As Object, ByVal e As EventArgs)
    ASPxSpinEdit1.Value = ASPxComboBox1.SelectedIndex
End Sub

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.
