Why do I receive the error
Input string was not in a correct format when my web form loads?
One of the more common reasons for this error is that the web control has a WorkflowGen field datatype (
FieldDataType) extended attribute specified that does not match the value type stored in the form data file.
For example, the following control has the
FieldDataType extended attribute set to
<asp:Label ID="REQUEST_AMOUNT" runat="server" FieldDataType="Currency" ></asp:Label>
In the form data,
REQUEST_AMOUNT contains a non-numeric value or, most often, a number with a comma, e.g.
The error normally occurs when updating an existing web form while there are other requests using the that same web form.
FieldDataType extended attribute is required, create a new version of the process and apply this
FieldDataType condition to new requests only.
