ASPxFileManager.ClientInstanceName Property

Specifies the ASPxFileManager‘s client programmatic identifier.

Namespace: DevExpress.Web

Assembly: DevExpress.Web.v24.1.dll

NuGet Package: DevExpress.Web


public string ClientInstanceName { get; set; }

Property Value

Type Default Description
String String.Empty

The control’s client identifier.


Use the ClientInstanceName property to specify a unique client-side identifier for the ASPxFileManager control. Use this identifier in the client side to access the ASPxClientFileManager object.

<dx:ASPxFileManager ID="fileManager" runat="server" ClientInstanceName="fileManager" >

<dx:ASPxButton ID="ASPxButton1" runat="server" Text="Clear" AutoPostBack="false">
     <ClientSideEvents Click="click" />

The ClientInstanceName property is important when a control is contained within a naming container, for instance, within an ASPxPageControl‘s page or an ASPxPopupControl‘s window.

If the ClientInstanceName property is not specified for a control, the control’s client identifier is generated automatically and equals the value of the control’s System.Web.UI.Control.ID property. Note that in this case, client-side programmatic access to the control is not allowed when the control is contained within a naming container.

Special Characters in Client Instance Name

If the ClientInstanceName property contains special characters, for instance, the dot (.), you cannot access a client object by this name. Call the GetByName(name) method to retrieve the client-side object instead.

<dx:ASPxTextBox ... ClientInstanceName="SomeType.SomeProp" />
var txt = ASPxClientControl.GetControlCollection().GetByName("SomeType.SomeProp");  
txt.SetText("Some Text");
