View 4 RepliesI setup a very simple example using a DetailsView and an EF Model with Contact, Individual, and Customer from the AdventureWorks database (2008). Viewing, Editing, and Deleting work just fine. However, I'm getting the error when I try to create a new Contact.
Here are the relevant code snippets:

I get the dreaded error:
Cannot insert the value NULL into column 'PasswordHash', table 'C1AdventureWorks.Person.Contact'; column does not allow nulls. INSERT fails.
I've monkeyed around with the StoreGeneratedPattern="Computed" and DefaultValue="0" for the PasswordHash property in the Contact entity as well, but it didn't .
I'm face of a little problem when using GridView, an EntityDatasource and entity custom properties using a partial class. I'll describe it and I hope that someone has already find the solution because I try to figured out since two days.
View 4 Repliesi've created a webform with one gridview having connected with the database using datasource. i.e password database with three colomn .
now want to insert the custom dropdown button using server control for each column.
when i select the dropdown list the list should display the value as required.
e.g if i click the uname dropdownlist then it should show the list of names.
if i click on pwd dropdownlist then it should show the list of numbers.
if i select any one of the value in the dropdown list then it should insert into the
database.
can i get code on this type of question...?
In my master page I have:
MembershipUser thisUser = Membership.GetUser();
loggedInUserID = thisUser.ProviderUserKey.ToString();
thisUser gives me access to all the fields in aspnet_Membership. I want a new field, isSubscribed for each user. I can use an SQL query to fetch the value fine, but I want to know if there is someway to modify the membershipuser object so it retrieves this value as well, so it is accessible from:
thisUser.isSubscribed.ToString();
I've read somewhere that ApplicationID is a unique id for a website (iis site path). But I'm still confused. When and why do I need this? I'm trying to implement asp.net membership for a website and I'll create some additional SQL tables (such as Companies, Services, etc) other than asp.net membership tables. So; do I need to include an ApplicationID column to these custom tables? Why?

I am able to save excel sheet from GridView perfectly. However, I need to add one custom column, which will be URL of a file on sever, I am not allowed to add URLs directly in the table (as per company's development policies).

I have a simple ASP.NET (Web Form) application. I created a separate project for my DAL. In the DAL, I have created an entity called Sites.
Now, I want to bind that to a form using an EntityDataSource control but it isn't visible. What am I doing wrong?
I made sure to reference the DAL.dll in the web project and include it in the code behind for the form. It's been a while since I've been in ASP.Net :-)
What my code does is that the EntityDataSource has a Where Parameter tied to the first DropDownList and it populates the second DropDownList, but when the first DDL changes, the EntityDataSource doesn't change the values of the second DDL. Worth mentioning this is inside a ModalPopupExtender which is inside an UpdatePanel. Maybe there is a way in just putting all the data in the second DropDownList and filter it depending on the value of the first one... or something like that... so there's no need of refreshing the data.

is it possible to use OFTYPE in where clause of an entitydatasource? I mean something like this:

I'm utterly new to APS.NET and in particular the MVC model...! I have a Telerik RadGrid control that I'm using. Until now (following NerdDinner) I was having the Model passed back to the view and this provided access to the various properties I wanted.
eg: Inherits="System.Web.Mvc.ViewPage<MySqlMvc.Helpers.PaginatedList<MySqlMvc.Models.Customer>>
.. lets me loop around the Model object and extract Customer data. This RadGrid control, however, needs me to use an EntityDataSource (hooked up via the designer). Does this have implications for maintaing the MVC pattern? I'm a little confused about how the EntityDataSource works in relation to my Model.EDIT: I do know there is an MVC version of the RadGrid but we also need the RadScheduler and a few others.. besides that, I'd still like to know the impact.
I use EF 4, C# and MS Membership Provider.
I have a GridView with DataSource an EntityDataSource web control.
I would like filter Data using EntityDataSource, filter show apply for the Current Logged-In User, this value should be taken using MS Memebership Provider ( Membership.GetUser(); ).
Now I cannot inf any Parameter in EntityDataSource that would allow me to dot that (in Where/Automatically generate a Where expression using provided parameter ).
I use MS SQL, EF 4 and C#.
I have a table in SQL fro "Categories" and I need populate a TreeView in my Asp.net page.
My question are:
1 - How can i populate the TreeView?
2 - How can i use the TreeView to modify the hierarchy of my Categories?
NOTE: I use "hierarchyid" SQL Columns!
CREATE TABLE dbo.CmsCategories
(
CategoryId int NOT NULL IDENTITY (0,1) -- Seed = 0 and Increment= 1
CONSTRAINT PK_CmsCategories_CategoryId PRIMARY KEY,
Title nvarchar(40) NOT NULL,
MetaDescription nvarchar(160) NOT NULL,
MetaKeyword nvarchar(128) NOT NULL,
Summary nvarchar(256) NOT NULL,
IsPublished bit NOT NULL
CONSTRAINT DF_CmsCategories_IsPublished DEFAULT 1,
CategoryNode hierarchyid NOT NULL,
CategoryNodeLevel AS CategoryNode.GetLevel()
);
I have an EntityDataSource and I need set WHERE to a Local Variable Type: GUID.
My problem is I am not able to send my local variable Guid to EntityDataSource for a WHERE OPERATION.
I also tried to to use a ControlParameter<asp:ControlParameter Name="UserId" /> and have a Label with Text property on my Guid converted in String. But does not work.
<asp:EntityDataSource ID="EntityDataSourceListAuthors" runat="server"
AutoGenerateWhereClause="True"
ConnectionString="name=CmsConnectionStringEntityDataModel"
DefaultContainerName="CmsConnectionStringEntityDataModel"

<asp:Parameter Name="UserId" />
</WhereParameters>

I've used EF4 EntityDataSources to do DataBinding with success, but here's a case where I'm stumped:
Table "CurrentComplaintsByUsers" has a foreign key over to a "Complaints" table. So in EF, I can access a CurrentComplaintByUser record, and navigate to its parent complaint like so:
var ccU = dataContext.CurrentComplaintsByUsers.First();
var parentComplaint = ccU.Complaint;
When I whip up an EntityDataSource based on CurrentComplaintsByUsers to bind a gridview, I want to get over from the "Complaint" object to an Assocation of Complaint called "Status". Here's a StatusID in my Complaint table, and so in code I can hit a complaint's status like so, including the Status properties:
string statusLabel = parentComplaint.Status.LabelText;
FAILURE: when I try to bake this all into an EntityDataSource, I can't get from my starting item "CurrentComplaintsByUsers" over to "Status". Here's my EDS:
<asp:EntityDataSource ID="edsCurrentCases" runat="server"
ConnectionString="name=EOCaseDataModel" DefaultContainerName="EOCaseDataModel"
EnableFlattening="False" EntitySetName="CurrentComplaintsByUsers"
Include="Complaint, Status">
</asp:EntityDataSource>
My error is this:
System.InvalidOperationException
"A specified Include path is not valid.
The EntityType 'EOCaseApp.CurrentComplaintsByUser' does not declare a navigation property with the name 'Status'."
I'm trying to get to the point where this works in my Gridview:
<%# ((CurrentComplaintsByUser)Container.DataItem).Complaint.Status.LabelText %>
So, using declaritive markup only, how do I get to a related objects associations from the EDS? (I can do it in code, just trying to use the EDS exclusively when I can)
Other notes: if I remove "Status" from the "Include" in the EDS, then I get a NULL ERROR when it hits ..Complaint.Status.LabelText in my Gridview, pretty much what you'd expect.
I have an A B AB (Many-to-Many?) table setup (where AB is the Linking Table for records in A and B by their IDs). Entity Framework 4.0 seems to create the EDM correctly (making an entity for A and B, and navigation property for AB). My problem is getting a GridView bound to an EntityDataSource to display columns from A with associated B records.
Here's my code:
[Code]....
The resulting GridView only shows columns from A. How do I get it to also show the associated columns from B? Do I have to explicitly define the columns or is AutoGenerateColumns smart enough to figure it out?
I am using EF 4 and EntityDataSource in a Page (WebForms).
This page contains a DropDownList that display UserName.
Data from this DropDownList it is from "aspnet_Users".
At the moment I am using a single EntityDataSource code belove:
<asp:EntityDataSource ID="EntityDataSourceListUsers" runat="server" ConnectionString="name=CmsConnectionStringEntityDataModel"
DefaultContainerName="CmsConnectionStringEntityDataModel" EnableFlattening="False"
EntitySetName="aspnet_Users" Select="it.[UserId], it.[UserName]">
</asp:EntityDataSource>
I need to FILTER the UserName associated to a specific ROLE and displaying it in the DropDownList therefore using others tables"aspnet_UsersInRoles" and "aspnet_Roles".
How to do it?
Would be great have a simple solution since I am a beginner.
i'm using an entitydatasource to save an entity which has an nullable integer property with the default value 0,this property is bound to a textbox in a formview.I assume that when I leave the textbox blank the datasource should understand that I want the property to have null and set it to 0 by default, but it acts different way, it doesn't save the enity at all and gives the entity in Updated and Inserted events as null:

I have a Entity Data Model with a number of tables in it. I have a web page that only has an EntityDataSource on it.In the code behind I am collecting some data that I am going to write to a SQL table What I want to do is call the EntityDataSource_Insert event and when it is fired it will call the EntityDataSource_Inserting event.
[Code]...
I have an application that uses EntityDataSource in many places. In the EDS, I manually build the Where clause based on user input from TextBox'es.
I would like the user to be able to enter "*" (asterisks) instead of "%" when querying data.
Is there an easy as using Entity SQL or the EDS itself to do a search/replace? I know I could actually change the TextBox after the data is entered, but when the user sees his text was changed from an * to a % I don't think he will understand.
I have tried using the T-SQL Replace command and doing something like this:
<asp:EntityDataSource ID="EDSParts" runat="server"
ConnectionString="name=TTEntities" DefaultContainerName="TTEntities"
EnableFlattening="False" EntitySetName="Parts"[code]....
But I get a "Server tag is not well formed" message. I can't find an equivalent "replace" function in the Entity SQL reference....
