Answer 1

We may need to see the CodeBehind for this page, and specifically the "Button1_Click" method (click event).

Now though, it appears as though you only have one of the labels with an ID of "lblFaultType" (maybe you misspelled that in your initial description. Each of the other labels all carry sequentially numbered IDs (e.g. ID="Label1", ID="Label2", ID="Label3", etc), and your ClickEvent (the Button1_Click method) will need to iterate through those items to know 'which' label you are attempting to obtain a value from.

Suggestion: It may be better to apply a ClickEvent on each of the particular labels since it will have the ID there with it (a JScript/JQuery solution).
