The 'LastLogin' property on 'User' could not be set to a 'null' value. You must set this prope

Posted By:      Posted Date: October 27, 2010    Points: 0   Category :ASP.Net

I get the following error message when running a LINQ statement to return a User object:

The 'LastLogin' property on 'User' could not be set to a 'null' value. You must set this property to a non-null value of type 'DateTime'.

The User class is generated by Entity Framework. How does one handle setting properties from database fields that are NULL?

Dim user As User = rep.Users.FirstOrDefault(Function(x) x.Username = userName)

The above line of code is the line that errors.

Thanks for any help

Category attribute of user control property does not work correctly in categories tab.



I have a User Control (ascx) and a property which a want to display in my categories tab in Visual Studio in the category named "Styles".

[Category("Styles"), DefaultValue(""), Description("The value for formating something.")]
public String MyFormatProperty
set { /* the code for set */; }
get { /* the code for get */; }

And here is the problem: Actually I do not need a get, because I only have to set the property (write only property). But when I omit the get, the property is displayed in the "Misc" category in the categories tab in Visual Studio. Only when I code the get as well, then the property is displayed correctly in the "Styles" category in the categories tab in Visual Studio.

Does anybody know why? How can I display the category correctly only with set?

Thanks, S.

error in MicrosoftAjax.js: Cannot read property '_notified' of null


I am cross testing my project with multiple browsers: IE7, Firefox and Chrome.

One one page I have a dynamically built table with two DropDownLists and CascadingDropDown extenders. Maybe the only thing special about the drop down lists is, that I add a "onChange" for the second drop down list in each row which shows or hides the list depending on the value populated from the web services.

All of this works perfectly in IE7 and Firefox, but Chrome does not execute the JavaScript in the onChange attribute and the error console says:

Uncaught TypeError: Cannot read property '_notified' of null

User Control and DataSourceID Property


I created a user control (.ascx) that contains a paging-user-control, a repeater and some other controls.
I want to use the property DataSourceID. How should I get the data from the datasource and when?
What is the recommended way?

I did it this way:
- Create a method to get the data by reflection, like:

private void PerformSelect()
	if (!String.IsNullOrEmpty(this.DataSourceID))
		Control control = Page.FindControl(this.DataSourceID);
		if (control == null)
			control = Parent.FindControl(this.DataSourceID);

		MethodInfo method = control.GetType().GetMethod("Select");
		IEnumerable data = (IEnumerable)method.Invoke(control, new object[0]);

		this.DataSource = data;
 - Call this method
In PageLoad when no postback
Changing the current page (paging-user-control)
Changing the current tab (tab-user-control)
Switching Visibility to true

I think that way is not the optimum, is there any better way?
Do you have any suggestions or links?

Thanks for your help, Andreas

User Control as Composite Control Property


I have a composite control (Called Dialog) which has a property "ContentControl"

At design time, I'd like this property to bind to a user control that is on the page.

When I add the items in the designer, the designer loads as expected.

However, when I try to run the web page, I get the following error:

Parser Error Message: Cannot create an object of type 'System.Web.UI.UserControl' from its string representation 'EditTerm1' for the 'ContentControl' property.

Please let me know if there is another way to bind a user control as a property of a composite control.


Designer Code:


	<cc1:Dialog ID="Dialog1" runat="server" Buttons="SaveCancel" 
Title="Edit Term" ContentControl="EditTerm1" />

Workflow 3.5 Activity property is null in condition and nowhere else

I have an activity that has properties that look something like this (they're set up as proper dependency properties, I just kept it simple here): public List<MyType> TypeList { get; set; }public Int32 Index { get; set; }public MyType SelectedType { get; set; } and an execution that just does this: SelectedType = TypeList[Index]; TypeList and Index are values that I set from other activities. I don't set SelectedType to anything in the activity properties, I just let it get set in the execution. Now I know for a fact that SelectedType is getting set properly, I can even point another activity to it and print out some values from it. So I'm quite positive that there's nothing wrong with that activity. However, I have an if activity with a condition that looks like this: ((MyActivity)GetActivityByName("activity1")).SelectedType != null and it evaluates to false (meaning it evaluated SelectedType as null). I'm pretty sure that that activity cast is correct (I do things like that all the time), and if it weren't wouldn't I get a null reference exception when trying to access SelectedType? So I'm pretty sure I'm not doing anything wrong here, but for some reason SelectedType is coming up null in that condition and no where else. It's almost as if the condition is being evaluated before the activity is being run, but the activity comes well before the condi

Interesting error message with content organiser: Cannot resolve mailbox (null) to a valid user

Here is a site with content organiser site feature enabled, as well as the email integration feature. Emails are successfully delivered to the "Submitted Email Records" list, but is never routed to the Drop Off Library. (the content organiser web service works fine and the drop off library works as a custom send to destination and happily processes its rules. If I turn up the debug juice I get the error "Cannot resolve mailbox (null) to a valid user" for every item in any "Submitted Email Records" in the site collection. Area: Document managagement Category: Content organiser EventID: 8000 Message: Cannot resolve mailbox (null) to a valid user I have temporarily worked around the problem by email enabling the drop off library but it creates an intermittent race condition (similar to certain workflow and event receiver situations), so its not a real solution (and in fact I assume thats why the Submitted Email Records hidden list exists in the first place). I've run procmon, specifically focusing on OSWTIMER and nothing interesting shows up at all. The error message is intriguing and I can't really think of what it is trying to do. In troubleshooting I noted that this farm had configured inbound email but not outbound email. I have since rectified this and de/reactivated the content organiser features and reset the timer service and IIS, b

Dynamic Binding of a Public Property in a User Control

Hi, I am not sure how to pass a variable from an .aspx page to an .ascx page.  I have a Control that puts rotating banners on a page.  The control has several public properties.  However, only one of those properties changes on the page level.  All the other properties are the same for every page site-wide.  So, instead of setting all the properties on every page in my sites (many sites), I want to set it up so I only have to setup the sitewide properties once and only the page level properties on each page.   I want to create a control with a property of AdKeyword="somename" and pass it to another control that will grab that page-level property and add it to all the other site-wide properties.  I guess what I need could be called a Dynamic Control Property.   My .aspx page has:<%@ Register TagPrefix="uc1" TagName="Banner1" Src="banner1.ascx" %> <asp:Content ID="Leaderboard" runat="server" ContentPlaceHolderID="Leaderboard"> <uc1:Banner1 AdKeyword="L2Chamber" runat="server" OverrideHeight="90" /> </asp:Content> My banner1.ascx page has:<%@ Control Language="VB" ClassName="UserControl297" %> <%@ register tagprefix="uc1&

How can I get a user list based on a specific profile property.

Hi,I am trying to query a DB and get a list of users based on a specific boolean property stored in the aspnet_profile for that user.I am aware that it wasn't possible a few years ago (http://forums.asp.net/p/988051/1277359.aspx), but was wondering whether that had changed in recent releases, or it was still not possible without trawling through the entire list of users and testing them one by one.  (My DB may become way to big for that.)Thanks in advance for any help.Regards,Ben

Validation error: This property can not be set to a null value [updated with test case!]

Hi, In a dynamic data web application, I get a validation error on a non-null nvarchar(50) column in ListDetails.aspx, even though I have entered a value which should be accepted. The validation error is: "This property cannot be set to a null value.". I can not reproduce this on northwind/adventureworks. Any ideas? UPDATE: I have created a complete test case: http://printf.no/DynamicDataBugTest.zip (The archive was scanned with the latest AVG definitions before uploading to my private secure dedicated FreeBSD server) The test case contains: One Dynamic Data Web App project One MS SQL Server 2005 database backup which contains a single table with three columns One screenshot showing how the error manifests itself I am fairly convinced now that this is a reproducible DD bug. -Andreas
