ScriptReference.Assembly Property

 

Gets or sets the name of the assembly that contains the client script file as an embedded resource.

Namespace:   System.Web.UI
Assembly:  System.Web.Extensions (in System.Web.Extensions.dll)

public string Assembly { get; set; }

Property Value

Type: System.String

The fully qualified or partially qualified name of the assembly that contains a client script file as an embedded resource.

You set the Assembly property when you reference a client script file that is included as an embedded resource in an assembly. Set Assembly to the fully qualified or partially qualified assembly name. A fully qualified assembly name includes a name, culture, public key, and version number. A partially qualified assembly name includes only a name.

When you specify a value for Assembly, you must also specify the name of the embedded resource in the Name property. Otherwise, an InvalidOperationException will be thrown.

The assembly being referenced must be located in either the Bin folder of the Web site or in the global assembly cache.

The following example shows how to reference a custom control and a JavaScript file that is embedded in the control assembly. The assembly is assumed to be in the Bin folder of the Web site. The custom control animates UpdatePanel controls. The JavaScript file is compiled as an embedded resource that is named SampleControl.UpdatePanelAnimation.js. You register the embedded JavaScript file by using the Assembly and Name properties.

To use this example, compile the JavaScript file that is shown in the example as an embedded resource with the custom control. Put the resulting assembly into the Bin folder of the Web site. For an example of how to embed a JavaScript file in an assembly, see Walkthrough: Embedding a JavaScript File as a Resource in an Assembly.

The following example shows a page that uses the custom control.

The following example shows the custom control class definition.

namespace SampleControl
{
    public class UpdatePanelAnimationWithClientResource : Control
    {
        private string _updatePanelID;
        private Color _borderColor;
        private Boolean _animate;
        public Color BorderColor
        {
            get
            {
                return _borderColor;
            }
            set
            {
                _borderColor = value;
            }
        }

        public string UpdatePanelID
        {
            get
            {
                return _updatePanelID;
            }
            set
            {
                _updatePanelID = value;
            }
        }

        public Boolean Animate
        {
            get
            {
                return _animate;
            }
            set
            {
                _animate = value;
            }
        }
        protected override void OnPreRender(EventArgs e)
        {
            base.OnPreRender(e);
            if (Animate)
            {

                UpdatePanel updatePanel = (UpdatePanel)FindControl(UpdatePanelID);

                string script = String.Format(
                   CultureInfo.InvariantCulture,
                   @"
Sys.Application.add_load(function(sender, args) {{
var {0}_borderAnimation = new BorderAnimation('{1}');    
var panelElement = document.getElementById('{0}');
     if (args.get_isPartialLoad()) {{
        {0}_borderAnimation.animate(panelElement);
    }}
}})
",
                   updatePanel.ClientID,
                   ColorTranslator.ToHtml(BorderColor));


                ScriptManager.RegisterStartupScript(
                    this,
                    typeof(UpdatePanelAnimationWithClientResource),
                    ClientID,
                    script,
                    true);
            }
        }
    }
}

The following example shows the supporting JavaScript file.

BorderAnimation = function(color) {
    this._color = color;
}

BorderAnimation.prototype = {
    animate: function(panelElement) {
        var s = panelElement.style;
        s.borderWidth = '2px';
        s.borderColor = this._color;
        s.borderStyle = 'solid';

        window.setTimeout(
            function() {{
                s.borderWidth = 0;
            }},
            500);
    }
}

The following example shows code that you must add to the AssemblyInfo file of the project that contains the custom control and the JavaScript file.
