Hi,
Actually I found out that NONE of the controls in the page exist when
the validation method is called. I mean even if I do a
FindControl("PicUpld") or a FindControl of ANY control the result will
always be a null reference.
However I found that the value entered in the HtmlInputFile control is
stored in ServerValidateEventArgs.Value. So I changed the method to:
protected void PicUpldVal_SrvrValidate(Object source,
ServerValidateEventArgs args)
{
String aVal = args.Value.Trim().ToLower();
args.IsValue = aVal.equals("") || aVal.EndsWith(".jpg") ||
aVal.EndsWith(".jpeg");
}
However now I ran into a different problem: Seems like the value
returned in IsValid is ignored, it doesn't matter if I change the code to:
protected void PicUpldVal_SrvrValidate(Object source,
ServerValidateEventArgs args)
{
args.IsValue = false;
}
I can see in the debuger that the execution threat is passing through
this method, so I am sure it is being called, but no error message, or
anything is displayed on the page :(
