asp.net formview problem updating data

Very strange behavior with formviews on asp.net.Â For some reason, if I declare the SqlDataSource on the page source but then do the binding of the SqlDataSource to the formview in code behind, no error are shown but the data does NOT get updated on edit.

So instead of doing this in code behind
summary.DataSourceID = "summaryDS"; summary.DataBind();

I need to do this on the page
runat="server" DataSourceID="summaryDS">

A previous problem I encountered with formview

.NET formview edit mode problem

I encountered problem with the formview not switching to edit mode using the standard commandname=”Edit” for a linkbutton.Â It turns out the problem was with the way I bind the data source to the formview through code behind.Â I changed that to defining the formview tag with the attribute of datasource while defining the data source on the page code and everything worked just fine.Â Go figure.

.NET Error “The password provided is invalid. Please enter a valid password value.”

Using the SqlMembershipProvider, you may encounter the error message, “The password provided is invalid. Please enter a valid password value. “, which is not very clear as to the exact problem. Apparently, the default setting in the .net membership configuration requires a password with a minimum of eight character and at least one non alpha numeric character such as “!@#$%^&*()”.
