The ASPxLabel control allows you to display text on a web page.

ASPxLabel - Label


  • Associate a Label with a Control

    You can associate a control with the Label control (ASPxLabel.AssociatedControlID). On a web page, a browser renders the label as an HTML label element. The label’s “for” attribute is set to the associated control’s ID property.

    <dx:ASPxLabel ID="ASPxLabel1" runat="server" AssociatedControlID="ASPxComboBox1" Text="ASPxLabel">
    <dx:ASPxComboBox ID="ASPxComboBox1" runat="server">
  • Appearance Customization

    You can customize control appearance as follows: apply a DevExpress Theme, style settings, or assign CSS classes.

    <script runat="server">
    protected void OnCheckedChanged(object s, EventArgs e) {
        Label.BackColor = (s as ASPxCheckBox).Checked ? System.Drawing.Color.Green : System.Drawing.Color.Red; 
    <dx:ASPxLabel runat="server" Text="Label Text" BackColor="Red" ID="Label" ForeColor="White" />
    <dx:ASPxCheckBox runat="server" Text="Successfull" OnCheckedChanged="OnCheckedChanged" AutoPostBack="true" />
  • Client-Side API

    The label control’s client-side API is implemented with JavaScript and exposed by the ASPxClientLabel object.
