Using Master Page Submits Null Fields To Database
Apr 6, 2010
Have created a Webform based on a master page.The code executes OK and sends data to the database, but inserts null values for all entries except the GetDate.
If I use exactly the same code in a new webform which isn't based on the master page, it inserts everything correctly.Here is a snippet from the form which uses the master page: -
<%@ Page Title="" Language="C#" MasterPageFile="~/SpeedDateMasterPage.master" %>
<script runat="server">
private void AddToDatabase(object source, EventArgs e) [code].....

I am adding text fields to a page from the database. I set the .ID to match the record ID from the database. Of course becasue the text field is on the masterpage, when I grab the .ClientID, it is ctl00 contentMain$ctl00. what I don't get is where is my ID? If I set it to say AB how do I find the textbox by AB? I thought it should have AB in the ID somewhere. ID is nothing which I don't get either. I'm looping through the controls in a placeholder like this
For Each row In dtData.Rows()
Dim c As Control
For Each c In phTextRequired.Controls
If c.UniqueID = row("CustomFieldID").ToString() Then
Again though what is in the row() is say AB but the id is way off from that.

I have multiple update panels with inside one or more text fields. Now I found out that when I update one update panel (with button inside update panel) all text fields are submitted, even them outside the update palen (and outside the validation group).
Is this correct behavior of the update panel?
How can I prevent submitting of all data? I only need the data of within the validation group.
This can be a huge performance issue when having an update panel in each tab (when using the tab panel).

I've got a master page where I've created two content place holders ('menu content place holder' and 'main body content place holder'). I've placed several controls (drop down lists and a calendar) in one of these content place holders (the 'menu content place holder'). In my content page I've set the 'menu content place holder' to 'Default to Master page content'. In my 'main body content place holder' I've included several controls (table, labels) which depend on the user selected items in the 'menu content place holder'.
After including a reference in all the necessary places- like this:
DropDownList ddlList1 = Master.FindControl("ddlList1")
as
DropDownList;
I still get the following exception (this exception occurs in my content page):
An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.
Exception Details:System.NullReferenceException: Object reference not set to an instance of an object.

My Original Issue here:Help! I've got repository access in my MVC master page! Refactor time!What originated as a re factoring job to improve performance has revealed new issues. If I should keep this in my original question - feel free to delete this one, and rename the old one to something more relevant. I'm using an ActionFilter applied to a base controller to load some user-customized settings. My issue is that I save these settings in the filterContext.Controller.ViewData object but its coming through as null on my master page. Here is the relevant code:
Action Filter
[AttributeUsage(AttributeTargets.Class, AllowMultiple = false)]
public class StoreSettingsActionFilter : ActionFilterAttribute

SelectCommand="SELECT CountryID, Title FROM Countries"/>
<asp:DropDownList ID="ddlCountries" runat="server" DataSourceID="sdsCountries"
DataValueField="CountryID" DataTextField="Title" AutoPostBack="True"

I am using the SQL Membership provider to handle authentication. On one particular page the main function is the registration of an asset. You have to log in first. No problem. I also have required field validators on this registration form that work nicely. The problem is, if you log in, go to that page, then click the 'logout' button, it seems to submit the form (bypassing all my validation in the process)! I know I can't be the first person to come across this, so I'm guessing I've set something up wrong somewhere.

I have an asp.net usercontrol located on on my aspx page. In the usercontrol there is a javascript function that I would like to fire everytime the page that contains the usercontrol submits to the server. (directly before this happens) Ideally I prefer to not have to write any code in the parent to make this happen, but I am not sure what the usercontrol may be capable of at this time. Can the usercontrol know that the page is submitting to the server and fire the function before this happens? Is there some sort of event that takes place here?

I have setup my business object to have a create_date and edit_date members both datetime datatypes. My company want to display the create_date and edit_date fields in a gridview for each transaction. The problem i have is that after insterting a record it will have a valid create_date but no edit_date and when displayed in the gridview it defaults to datetime.minvalue (My default). How on earth do i show an empty field in my gridview for a null datetime field in the database?
I am using similar architecture to the Imar Spaanjaars example of a tiered solution. With a few small tweeks it has worked well for me for ages. I am passing a List<Database> to my object datasource which connects to my gridview.

So i'm working on the form that i started MVC with - the problem is that i'm NOT using a ViewModel for the view, its an actual Linq to SQL object. And so far it works fine. This form is a beast and id rather not refactor it to use viewmodels....
My big problem now is that depending some condition, i pretty much set almost everything to disabled when a particular dropdown is selcted (to mimic a deactivated state) - when the user hits submit, the model fields are now null, even tho you can see them filled in (just greyed out and unselectable) and validation refuses them.
Is there anyway around this other than to refactor the Views to use ViewModels (and set different validation rules so submit works)?

How do I check if my value is empty AND Isnull? I need to check for both, using ISNULL is not enough because the data can change just so that it is empty.
how I can change my query to accommodate this?

I'm using MVC 2 with some Models from a LinqToSql project that I built. I see that when I post back to a Controller Action after editing a form that has a DateTime field from the Model, the MVC Html.ValidationMessageFor() helper will nicely display an error beside the Date text box. This seems to happen automatically when the you test ModelState.IsValid() in the Controller Action, as if the MVC model binding automatically knows that the DateTime field cannot be empty.
My question is... I have some other string fields in these LinqToSql generated classes that are Not-Nullable (marked as Not Nullable in Sql Server which passes thourgh to the LinqToSql generated classes), so why doesn't Mr. MVC pick up on those as well and display a "Required" message in the ValidationMessageFor() placeholders I have added for those fields?
Sure, I have successfully added the MetadataType(typeof<t>) buddy classes to cover these Non-nullable string fields, but it sure does seem redundant to add all this metadata in buddy classes when the LinqToSql generated classes already contain enough info that MVC could sniff out. It MVC validation works with DateTime automatically, why not these Not-nullable fields too?

I am using the DetailsView Control to read a LastUpdatedDate field (which can be null until an update is performed) from the database. The LastUpdatedDate is of type DateTime saved in UTC. With the DetailsView control, I can use the NullDisplayText property of the boundfield to safely display an custom message. However, once converted to a template field, that property is lost. Now, how would I display that message if the field is null as I am also formatting the date for display to show in local time.

I have a Gridview showing the data on one of my tables, and when I try to edit the data in one of the columns after I click update, rather than updating the record with the new value I typed in, the rows become null as in, everything in the row I just edited disappears. This inmediatly makes my application crash because one of the fields in my table (IssueDescription) doesn't allows null values.
This is the code, which is actually 100% auto-generated from when I created the GridView control and specified in the options to implement update, delete, edit options.
<asp:GridView ID="GridView1" runat="server" AllowPaging="True"
AutoGenerateColumns="False" DataKeyNames="ticketNum"
DataSourceID="SqlDataSource1" [code].....
What is making the rows turn into null after the update? I did some research and tried to define the Update behaviour myself using RowUpdating function. After hours of learning how to use it I got it to "work", but because the Update turns everything to null when it updates, the sqlconnection command I use to do the query sends null anyways. I can paste the C# code if you'd like to see it, though I'd rather not use it if the auto-generated by asp above can be fixed instead.

How to make the linq throw error, when not null columns are there in the table.
Why I am saying, it is. I tried to add to column in the table. Linq throwed error os some sort. I could not understand. it was like some innner table etc.
I had to resort to native sql, which showed the error, as the not null fields are there in the table.
