MSOButton

Type: System.Boolean
Required. Indicates whether the named command’s button picture is an Office picture. True = button. If MSOButton is False, then Bitmap is the ID of a 16×16 bitmap resource (but not an icon resource) in a Visual C++ resource DLL that must reside in a folder with the language’s locale identifier (1033 for English).

Bitmap

Type: System.Int32
Optional. The ID of a bitmap to display on the button.

Luckily, someone else on the internet has stepped up and done the work.  Here is a link to their site:

Everything was going great until i realized that I needed to have two layers of collections, I needed my first collection (TransformGroup) to have an attribute that I could use as an identification key later on in the code.  No matter what I did I could not get the configuration manager to read the custom attribute on the “TransformGroup” configurationelementcollection.  When you want a property read by the configuration manager during the GetSection call you are suppose to just add the “ConfigurationProperty” attribute to your property statement in your class like so:

<ConfigurationProperty("Name", IsKey:=True, isrequired:=True)> _
Public Property Name() As String
         Get
                Return DirectCast(Me("Name"), String)
         End Get
         Set(ByVal value As String)
                Me("Name") = value
         End Set
End Property

This works fine when you inherit from the configurationelement and you get access to the base collection via the Me(“SomeAttributeName”) statements  but when you try the same thing in a class that inherits from configurationelementcollection you get an error because the base collection contains in this case “Transform” elements, not attributes read from the element.  After some time of searching and a little bit of trial and error I figured out a hack.  What you have to do is use the “OnDeserializeUnrecognizedAttribute” method.  You can override this method in you class and when the configuration manager finds any attributes on your xml that are not defined by a class somewhere it calls this method allowing you to do something with what it found.  For my solution I just created a property on my “TransformGroup” class called group name and did not add any code attributes to it, then I overrided the method like this:

Protected Overrides Function OnDeserializeUnrecognizedAttribute(ByVal name As String, ByVal value As String) As Boolean
        If (name = "GroupName") Then
               Me._GroupName = value
               Return True
        End If
        Return MyBase.OnDeserializeUnrecognizedAttribute(name, value)
End Function

It is a bit of a hack but it works.  All you have to do is return true from this function, otherwise .Net will throw an exception.

protected virtual void RaisePostBackEvent(string eventArgument)
{
     base.ValidateEvent(this.UniqueID, eventArgument);
     if (this.CausesValidation)
     {
         this.Page.Validate(this.ValidationGroup);
     }
     this.OnClick(EventArgs.Empty);
     this.OnCommand(new CommandEventArgs(this.CommandName, this.CommandArgument));
}

Notice how the last line in this code calls “this.OnCommand” and passes a CommandEventArgs instance with command name and command argument.  The button and link button have this extra code while the checkbox does not.  The code for this method looks like this:

protected virtual void OnCommand(CommandEventArgs e)
{
    CommandEventHandler handler = (CommandEventHandler) base.Events[EventCommand];
    if (handler != null)
    {
        handler(this, e);
    }
    base.RaiseBubbleEvent(this, e);
}

All the magic that makes the button and link button work is right here.  Calling “base.RaiseBubbleEvent” and passing it the same CommandEventArgs from above allows the repeater control to catch this event later on in its OnBubbleEvent.  The on bubble event for the repeater looks like this:

protected override bool OnBubbleEvent(object sender, EventArgs e)
{
    bool flag = false;
    if (e is RepeaterCommandEventArgs)
    {
        this.OnItemCommand((RepeaterCommandEventArgs) e);
        flag = true;
    }
    return flag;
}

The ItemCommand event is only fired here and only if the eventargs type is RepeaterCommandEventArgs.  Since the standard CheckBox control does not call the RaiseBubbleEvent like a button or link button it’s checkchanged event will never make it here.  But there is a very simple solution to make it work this way, all you have to do is create a custom checkbox control that calls RaiseBubbleEvent during it’s OnCheckChanged event.  Here is a an example, this CheckBoxRepeaterAware control is the same as a regular CheckBox except for the addition of two properties and an overridden OnCheckChanged event.

public class CheckBoxRepeaterAware : CheckBox
{
   #region Properties

   #region CommandName

   public string CommandName
   {
       get
        {
            if (this.ViewState["CommandName"] == null)
            {
                return string.Empty;
            }
            else
            {
                return this.ViewState["CommandName"] as string;
            }
        }
        set
        {
            this.ViewState["CommandName"] = value;
        }
    }

    #endregion

    #region CommandArgument

    public string CommandArgument
    {
        get
        {
            if (this.ViewState["CommandArgument"] == null)
            {
                return string.Empty;
            }
            else
            {
                return this.ViewState["CommandArgument"] as string;
            }
        }
        set
        {
            this.ViewState["CommandArgument"] = value;
        }
    }

    #endregion

    #endregion

    #region Procedures

    #region On Checked Changed

    protected override void OnCheckedChanged(EventArgs e)
    {
        //create a new event args of type command event args
        CommandEventArgs ce = new CommandEventArgs(this.CommandName, this.CommandArgument);

        //allow the base checkbox to handle the event as normal
        base.OnCheckedChanged(e);

        //raise the contorls method RaiseBubbleEvent
        base.RaiseBubbleEvent(this, ce);

    }
    #endregion

    #endregion

}

As you can tell, in the OnCheckChanged event we are calling “base.RaiseBubbleEvent” and passing it the command name and command argument.  By doing this, the repeater will be able to fire it’s ItemCommand event for us.  Again, I am not sure why Microsoft didn’t just implement this in the first place for the check box control but at least the framework is flexible enough that we can do it now.  The last thing we need to do to make this solution even easier is add a tag mapping in our web config to allow the new CheckBoxRepeaterAware control to replace all instances of CheckBox controls in our application.  To do that we add the following to the web config inside the pages node:

<tagMapping>
    <add tagType="System.Web.UI.WebControls.CheckBox" mappedTagType="CheckBoxRepeaterAwareDemo.Classes.CheckBoxRepeaterAware"/>
</tagMapping>

My favorite part is the pants at the end
