ASPxObjectContainer.ClientInstanceName Property

Gets or sets the ASPxObjectContainer‘s client programmatic identifier.

Namespace: DevExpress.Web

Assembly: DevExpress.Web.v21.1.dll

Declaration

[DefaultValue("")]
public string ClientInstanceName { get; set; }

Property Value

Type Default Description
String

String.Empty

A string value that specifies the ASPxObjectContainer‘s client identifier.

Remarks

Use the ClientInstanceName property to specify a unique client-side identifier for the ASPxObjectContainer control. The ClientInstanceName property’s value can be used on the client side to programmatically access the client object rendered for the ASPxObjectContainer control in client-side script. This property is particularly important in referencing the ASPxObjectContainer control when it 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 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.

Note that it’s not recommended to define the same identifier for the ID and ClientInstanceName properties of the ASPxObjectContainer control. Doing this might lead to a JavaScript error generated when accessing the control on the client, using the ClientInstanceName property’s value. As a workaround, you can add a “window.” prefix when accessing the control:

window.ASPxObjectContainer1.Play();

But, it’s better to use different names for the ASPxObjectContainer‘s ID and ClientInstanceName properties, and the ClientInstanceName property’s value shouldn’t coincide with any HTML element identifier on that specific page.

NOTE

The client-side programmatic interface is available if the ASPxObjectContainer.EnableClientSideAPI property is set to true.
