Isolate Which Parameter Is Throwing Error In Insert Method?
Nov 21, 2010
I'm passing parameters (over 30 in all) from a system.data.dataset into a tableadapter insert method, but I'm getting an "Input string was not in a correct format" exception.The error points to the method that is throwing, which is great, but is there a way I can tell exactly which parameter is throwing the error?(Sorry about the code formatting -- I fought with it for 5 minutes before giving up)

I've got a simple detailsview on a webpage for viewing, adding, and updating inspectors. Since it is a simple details view I'm just used the datasource select, update, delete, and insert commands. When I debug the page it populates the detailsview appropriately and allows me to page through the inspectors but when I try to update a field I'm getting the implicit conversion error in the attached doc. Below is my detail view markup. I was thinking the error is caused by the checkbox type being boolean while the SQL type for "Active" is bit but I've tried to use various conversion methods and can't seem to get them to work.
when a user enters a bad email I am doing a check on this and throwing an exception message as follows, this works fine on the test site but for some reason the same code on the live site gives a "internal server error" (http code 500). The code below:

not certain why this is happening, I assume that it's some server or config difference between the test and live sites. has anyone seen this before? For a quick fix i'm registering javascript alert and showing the same text so it works but I would like to figure out why the code above is not working.

The root application on http://myserver is the cms application that needs to be isolated entirely from the other applications. Is this possible in ASP.NET and how do I go about doing it? Right now when I run sub_app1, I get a DLL binding error for a DLL that is only used in the root application.

A single table defined in an Entity model in ASP.net v4, the model is bound directly to a GridView with AutoGenerateEditButton enabled.However, each time I hit edit, then save, the page throws the error "Update is disabled for this control" for which I cannot find a solution.What is causing this error? What can do to resolve it?
