Overloading a return value to a property in a webcontrol. Ambiguous Match Found Error.

Andre Vianna

I'm creating a CustomGridView based (of course) on the GridView. I'm writen my on PagerProperties with a diferent class and diferent properties. Everything works ok with the default values but if I set any value I receive the "Ambiguous Match Found" error. Here is a sample code of what is happening:

public sealed class MyPagerSettings : IStateManager {

...
[Category("Appearance")]
[DefaultValue(true)]
[NotifyParentProperty(true)]
public bool Visible {
get { return (bool?)mViewState["Visible"] ?? true; }
set { mViewState["Visible"] = value; }
}

...
}

public class MyGridView : GridView {

...

MyPagerSettings mPagerSettings;


\[Category("Paging")\]
\[DesignerSerializationVisibility(DesignerSerializationVisibility.Content)\]
\[NotifyParentProperty(true)\]
\[PersistenceMode(PersistenceMode.InnerProperty)\]
`new` public virtual MyPagerSettings PagerSettings {
	get {
		if (mPagerSettings == null) {
			mPagerSettings = new MyPagerSettings(this);
			if (IsTrackingViewState)
				((IStateManager)mPagerSettings).TrackViewState();
		}
		return mPagerSettings;
	}
}

...

}

The new modifier should hide the base property. On the consuming page:

		<awc:MyGridView ID="MyGridView1" runat="server" AllowPaging="True" PageSize="10">
			`<PagerSettings Visible=false />   <-- The error happens here!`
			<Columns>

...
</Columns>
</awc:MyGridView>

Please any help on how to work around it? Please... I don't want to change the name of the property!!! So no obvious answers please. Thanks.
