Programmatical change Label.Text of a set of labels in an UpdatePanel

I write engineering solutions in VB. In most cases they need to operate in both metric and English units of measure so I need to update labels such as °F and °C appropriately. I have a number of labels in an UpdatePanel that need this sort of update. Some need to switch between °F and °C while others betweem feet and meters. Which type of units of measure to use is known at Page_Load so I thought I could just make the Label.IDs meaningful (use lblTemp1, lblTemp2 etc for temperature units) and then update their .Text property based on their ID and the units of measure. I am almost there but I can't seem to gain access to the Text property once I ahve found a Label's whose text I want to change.

Dim iAsInteger = 0

Dim myLabelAs Label

'controls I want to update are in and UpdatePanel...

ForEach ctrlAs ControlIn UpdatePanel1.Controls'check to nake sure it actually has controls first...

If ctrl.HasControls()Then'cycle through all controls in the UpdatePanel...

For i = 1To ctrl.Controls.Count

'if this is a Label then

IfTypeOf ctrl.Controls(i)Is LabelThen

'if the label ID contains "lblTemp this is a temperature unit and must be updatedIf ctrl.Controls(i).ID.ToString.Contains("lblTemp")Then

'HERE IS WHERE THE PROBLEM EXISTS...'can not gain access to the Text property

myLabel =

CType(ctrl, Label)

If uofm = SIUnitsThen 'metric

myLabel.Text =

"°C"Else

myLabel.Text =

"°F"EndIfEndIfEndIfNextEndIfNext

What error do you get? Can you post your ASP.NET code?

What kind of error you are facing ??

Post it here...

The error message I currently get is due to a casting error in the line.Unable to cast object of type 'System.Web.UI.Control' to type 'System.Web.UI.WebControls.Label'.

myLabel =CType(ctrl, Label)

At this point in the code I have found a control and determined that it is in fact a Label who's Text property I need to change. However there is no Text property for the crtl so I am trying to cast the ctrl as a Label.
