set property of a control

[Sharon]

Hi all

I need to change some of my controls properties at run time,

I build this function in C# which sets some simple properties

I want to add some more properties, and extend the use, but my switch
statement is getting bigger and bigger.

Am I doing it right? Is there any other way to do this?

Thank you

Sharon

setControlProperty(this.button1,BACKCOLOR,Color.Re d.ToArgb());

Well, you can do it using reflection - use typeof(Control).GetProperty,
and then call SetValue on the PropertyInfo which is returned.

Thank you Jon

I don't understand what are all the SetValue prams ?

Is it supposed to be like this:

private void setControlProperty(Control ctr,string property,Object val)

{

ctr.GetType().GetProperty(property).SetValue(val);

}

Thank you

Look in MSDN for the details.
Is it supposed to be like this:

No. You need to specify the instance to set the property on - the type
isn't specific to the instance.

There are examples in MSDN though, I believe.

thank you Jon

it was :
Color rndColor = Color.FromArgb(rand.Next(255),
rand.Next(255),rand.Next(255) ) ;

myPropertyInfo = _myControlType.GetProperty("BackColor");

myPropertyInfo.SetValue(_myControl, rndColor, null);
