Hi

I have health monitoring turned on, and i have the following error i'm trying to understand:

Exception:

Exception information:
    Exception type: System.InvalidCastException
    Exception message: Specified cast is not valid.


Thread information:
    Thread ID: 5
    Thread account name: NT AUTHORITY\NETWORK SERVICE
    Is impersonating: False
    Stack trace:    at _Default.Repeater1_ItemDataBound(Object sender, RepeaterItemEventArgs e)
   at System.Web.UI.WebControls.Repeater.CreateControlHierarchy(Boolean useDataSource)
   at System.Web.UI.WebControls.Repeater.OnDataBinding(EventArgs e)
   at _Default.up1_Load()
   at _Default.Timer1_Tick(Object sender, EventArgs e)
   at System.Web.UI.Timer.OnTick(EventArgs e)
   at System.Web.UI.Page.RaisePostBackEvent(IPostBackEventHandler sourceControl, String eventArgument)
   at System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint)

I'm just trying to figure out exactly where the problem is happening and what it is - is it happening in the Repeater1_ItemDataBound sub routine, or in the Timer1_Tick sub routine? Is the last thing that happened before the error occured at the top or bottom of the trace?

any help much appreciated

thanks
