C# User Controls - setting default properties

[countd4]

I have built a working user control. However, to make it work, I always have
to set certian properties using the properties sheet for the control when
using it on other forms. I want to be able to set default values for most
properties so the control will work as-is without requiring the developer to
set them.

I notice in the compment initialization code create when I drop the control
on a form that all the properties are set to null or other appropriate
'empty' values. How can I modify the control so these initial values are
correct?

Thanks!

private bool myBoolProperty = false;

public bool MyBoolProperty
{
get { return myBoolProperty; }
set { myBoolProperty = value; }
}

Re: C# User Controls - setting default properties


That is how the properties are implemented. The problem is not that I can't
see them on the new project. The problem is that they are being assigned null
values by the IDE. So I am guessing that I'm not doing something correctly in
the control itself to propagate the "default" values. Here are some code
snipets from the control.

public class ProgressControl 1 : System.Windows. Forms.UserContr ol
{
private string _spinLocation = "L" ; // 'L'eft or 'R'ight
private string _pcntLocation = "R" ; // 'L'eft or 'R'ight
..
..
}
..
..
public ProgressControl 1()
{
// This call is required by the Windows.Forms Form Designer.
InitializeCompo nent();

// TODO: Add any initialization after the InitComponent call

}

..
..
..
public string PBSpinLocation
{
get {return _spinLocation;}
set {_spinLocation = value;}
}
public string PBPcntLocation
{
get {return _pcntLocation;}
set {_pcntLocation = value;}
}
..
..

Now here is what the IDE does when I drop this control on a new project form:

private void InitializeCompo nent()
{
..
..
//
// progressControl 11
//
this.progressCo ntrol11.Accessi bleRole =
System.Windows. Forms.Accessibl eRole.None;
this.progressCo ntrol11.BackCol or = System.Drawing. Color.Plum;
this.progressCo ntrol11.Locatio n = new System.Drawing. Point(24, 8);
this.progressCo ntrol11.Name = "progressContro l11";
this.progressCo ntrol11.PBarFil lColor = System.Drawing. Color.Empty;
this.progressCo ntrol11.PBAutoM ax = false;
this.progressCo ntrol11.PBPcntB ackColor = System.Drawing. Color.Empty;
this.progressCo ntrol11.PBPcntD isplay = true;
this.progressCo ntrol11.PBPcntF ont = null;
this.progressCo ntrol11.PBPcntF ontColor = System.Drawing. Color.Empty;
this.progressCo ntrol11.PBPcntL ocation = null;
this.progressCo ntrol11.PBSpinB ackColor = System.Drawing. Color.Empty;
this.progressCo ntrol11.PBSpinD isplay = true;
this.progressCo ntrol11.PBSpinF ont = null;
this.progressCo ntrol11.PBSpinF ontColor = System.Drawing. Color.Empty;
this.progressCo ntrol11.PBSpinL ocation = null;
this.progressCo ntrol11.Size = new System.Drawing. Size(280, 96);
this.progressCo ntrol11.TabInde x = 0;
//
..
..
..

So you see how it forces most of the public properties of the control to
null or empty states? This is my problem!!!

Re: C# User Controls - setting default properties

What you're looking for is a custom ControDesigner for your control which
can, among a lot of other things, create the default properties when your
control is dropped onto a form.

Look up the System.Windows. Forms.Design.Co ntrolDesigner class and override
the OnSetComponentD efaults() method.
