About User Controls

[Raj]

Hi,

I have created a Windows 'user control' in C#.NET. This user control defines
several public 'properties' that the outer world can use to tweak the
behavior of the user control. However, whenver I drag the user control to a
Form, I noticed that the 'Windows Form Designer generated code' contains
several auto generated statments to initialize the 'properties' that are not
proper. This causes the Form designer to get corrupt and shows a designer
error in design mode. This happens each time I build the code!!!

The property that is defined is
public object[] UserControlData
{ set { }

get { }

}

and it is getting assigned the foll value due to which it is getting
corrupted:
this.expertTimeline1.UserControlData = new object[0] { new System.Double[]
{

1E+108}, new System.Double[] {1E+108}};


Is there someway to prevent the auto generation of code?
Is there some way to define default values for the properties?
Is there something wrong in the way I am defining the methods?


Thanks & Regards,
Raj

Hi,

1.
You could control the designer-code-generation using the
DesignerSerializationVisibility attribute.

MSDN:
http://msdn.microsoft.com/library/e...designerserializationvisibilityclasstopic.asp

2.
Use the DefaultValueAttribute to specify default values the designer would
use.

MSDN:

3.
Well, you could use the Component.DesignMode property to render contents
only if the component is properly initialized.

Does this address all your issues?
