Hi!

I'm developing custom control with two panels. I'll make just onlyone panel have controls.

so, I used 'EnableDesignMode'. below is my code

[Designer(typeof(WPCTest.WPCTestDesigner))]
public partial class WPCTest : UserControl
{
public Panel Area { get { return this.panel2; } }

internal class WPCTestDesigner : ParentControlDesigner
{
public override void Initialize(IComponent component)
{
base.Initialize(component);

EnableDesignMode(((WPCTest)component).Area, "Area");
}
}
}

In Designer, user can design Form using custom control (for example, I added a Button into custom control).but, at run-time, the child controls of the custom control disappear.

so, I saw the generated code written by Windows Form Designer.

then, I found the factthat thechild controlswere generated but were not added into the ControlCollection of custom control.

below is the the generated code written by Windows Form Designer.

this.wpcTest1 = new WPCTest();
this.button1 = new System.Windows.Forms.Button();
// wpcTest1
//
this.wpcTest1.Location = new System.Drawing.Point(51, 23);
this.wpcTest1.Name = "wpcTest1";
this.wpcTest1.Size = new System.Drawing.Size(150, 150);
this.wpcTest1.TabIndex = 0;

I have never developed custom control. so, I have no idea about how to fix this problem.

Please help me.

I found a article. (http://blogs.msdn.com/subhagpo/archive/2005/03/21/399782.aspx)

the article says to add the attribute on the property (Area) that tells the code generator to write out code for the value contanised in this property.

so, add this attribute on Area property

[DesignerSerializationVisibility(DesignerSerializationVisibility.Content)]

public Panel Area { get { return this.panel2; } }

it works well.

thanks
