Namespace: Wisej.Web.Ext.AspNetControl

Assembly: Wisej.Web.Ext.AspNetControl (4.1.0.0)

• Control
  • IFramePanel
    • AspNetWrapperBase

Base non-generic class for AspNetWrapperBase.

C#

public abstract class AspNetWrapperBase : IFramePanel

VB.NET

Public MustInherit Class AspNetWrapperBase
    Inherits IFramePanel

Constructors

AspNetWrapperBase()

Initializes a new instance of AspNetWrapper.

The new instance saves the VIEWSTATE of the ASP.NET page in the Wisej session (see UseSessionViewState). This class is abstract: derive from AspNetWrapper to wrap a specific ASP.NET control.

Example:

The following example creates a wrapper that stores the VIEWSTATE in the page instead of the Wisej session:

public class CalendarWrapper : AspNetWrapper<System.Web.UI.WebControls.Calendar>
{
    public CalendarWrapper()
    {
        this.UseSessionViewState = false;
    }
}

Properties

IsAsync

Boolean: Returns whether the current request is an asynchronous postback.

IsCallback

Boolean: Returns whether the current request is a callback.

IsPostBack

Boolean: Returns whether the current request is a postback.

Page

Page: Returns the instance of the internal page used to wrap the ASP.NET control. It is valid only during the processing of the Init or the Load events.

ScriptManager

ScriptManager: Returns the instance of the ScriptManager in the AspNetHost.asp page used to wrap AspNet controls.

UseSessionViewState

Boolean: Determines whether Wisej saves the VIEWSTATE in memory. The default is true.

ViewState

Object: VIEWSTATE saved using Wisej sessions.

WrappedControl

WebControl: Returns the instance of the wrapped ASP.NET control. It is valid only during the processing of the Init or the Load events.

Update()

Causes the control to update the corresponding client side widget. When in design mode, causes the rendered control to update its entire surface in the designer.

Calling this method changes the URL of the inner IFrame, which reloads the host page and runs the ASP.NET page life cycle again. Use it to apply property values that are copied to WrappedControl in the Init or Load events.

Example:

The following example reloads a wrapped calendar when its date changes on the server:

public class CalendarWrapper : AspNetWrapper<System.Web.UI.WebControls.Calendar>
{
    public DateTime VisibleDate
    {
        get { return this._visibleDate; }
        set
        {
            if (this._visibleDate != value)
            {
                this._visibleDate = value;
                Update();
            }
        }
    }
    private DateTime _visibleDate = DateTime.Today;

    protected override void OnLoad(EventArgs e)
    {
        base.OnLoad(e);
        this.WrappedControl.VisibleDate = this._visibleDate;
    }
}
