propertyinfo.se tvalue

This part is easy:
Dim oControl As Control

oControl = Me.Page.FindCon trol("TextBox1" )

Dim oPropertyInfo As PropertyInfo

oPropertyInfo = oControl.GetTyp e.GetProperty(" Text")

oPropertyInfo.S etValue(oContro l, "Some New Text", Nothing)

What about in the case when the property may have properties that need to be
changed?

For instance the Infragistics WebTextEdit control, I couldn't quickly find a
vb control example, has a property named "ButtonsAppeara nce" which has a
property named "CustomButtonTo olTip". The following code produces a
targetexception .

oControl = Me.Page.FindCon trol("WebTextEd it1")

Dim oPropertyInfo As PropertyInfo

oPropertyInfo = oControl.GetTyp e.GetProperty(" ButtonsAppearan ce")

oPropertyInfo =
oPropertyInfo.P ropertyType.Get Property("Custo mButtonTooltip" )

oPropertyInfo.S etValue(oContro l, "Some New Text", Nothing)

I don't believe oControl is the correct target here but am at a loss as to
how to provide the correct target. Any suggestions?

I wanted to pass on what I have found.

The ButtonsAppearan ce Property is READ ONLY. So is every other Property
whose Value is not a value type; I only perused Visual Studio and
Infragistics controls. Therefore it will not be possible to make changes to
these properties at runtime. If anyone resolves the TargetException , I'd be
interested in seeing the code.

I am trying to write a subroutine that will examine all the properties of a form to determine which of those are SqlCommand objects, and then set the Connection property of those SqlCommands to a passed-in SqlCommand object. I can find the properties OK but am unsuccessful in trying to change their value due to the way I have identified those SqlCommand objects (as a PropertyInfo). Can anyone give me a hint (or suggest a better way) as...

I have adapted the following code from the MSDN help for PropertyInfo SetValue. In the original code, the structure MyStructure is defined as a class MyProperty, and it works as expected. There is also a minor change in class Mypropertyinfo, which I have commented out. When using a structure, however, the second call to GetValue returns "Default caption". Can anyone tell me why, and how I can make this work? <code> Imports System

I've read that Reflection is slow and shouldn't be used when performance is a concern. In my case, performance is definitely a concern, so I was thinking that I could collect the PropertyInfo objects that I need at initialization, and then just call PropertyInfo.SetValue() at runtime. Can anyone tell me 1) how expensive is the call to PropertyInfo.SetValue() ? and 2) what is a better alternative ? I already have a hand-made solution...

Hi, I need to invoke .getvalue and .setvalue on fieldinfo and propetyinfo objects. Even though they're both derived from MemberInfo, they don't share those two methods. I've finding myself writing the following types of structure over and over. Is there something I'm missing? Or some 'funky' 3.5 delegate/lambda expression way of doing this? Thanks very much in advance,
