View 4 Repliesi have an already existing schema (in a xsd file). now i need to prepare a report, so in the rdlc page i take a table. now how can i set the schema as a dataset to the table?(i'm getting an error -- "the table 'table1' is in the report body but the report has no data set. Data regions are not allowed in reports without datasets.").
View 1 RepliesI am using LINQ to SQL with C#. Is there a method through which we can generate entity class files from the table schema? By dragging tables onto the graphical designer classes are generated but they are not the real class files(i mean actual files with the extension cs).
I am aware of that we can code the class files first and then create the schema manually or programmatically, but i wanted to know if the reverse is possible, may be using some third-party tools. I feel it will be very convenient to use LINQ that way.
I work with a ASP.NET UI framework that pulls fields for a particular screen off a database. These fields can be associated with particular data fields in another database for binding. The idea with this setup is that if a client needs a new column on a table, they can easily add it, and create a UI field that binds to it without any sort of application restart or recompile.
The problem I've always had with this is that it has meant I'm always having to work with untyped datasets in my code. Are there any ORM libraries for .NET out there that could easily accommodate the requirement of being able to access arbitrary columns in the table schema over and above ones mapped to strongly typed fields?

I'm working on a new project where I have the luxury of working from a Model to Database approach using Entity Framework 4.
The project I'm working on is taking an agile approach where different phases will be rolled out over time.
Will the Model First approach work in my case? I noticed when you "Generate Database from Model" it recreates the entire schema from scratch which will obviously wipe all the data that is in the db. I was hoping for a more "Update Database from Model" approach where the db would just be altered to reflect the changes rather than recreated
if there is any easier way to synchronize the TypedDataSets with the chages made to backend Table / Stored Procedure schema. I use Typed DataSets in my project extensively and I found them very useful and easier to code, but difficult to maintain
The difficuly I have always faced is whenever there is a change in a backend database table structure or stored procedure that is linked to any of the Typed DataSet in our project requires to recreate whole DataSet again by scrapping the old one. The backend changes will not be reflected unless and untill you recreate the whole stuff again.
Is there any easier way to synchronize those typed datasets with the changes made to backend database schema or any other workaround that will not required to recreate the whole DataSet again.
using gridview to show data from table. on the aspx page i want to hide/show image depending on the value of one of the fields of a table. for e.g. say is_new=1 then show else hide where is_new is table field.
for this on aspx page i have one img element whose initial visible property is set to false. Now at runtime i want to show/hide image depending on value in each record. So what coding needs to be done and where?

I have a SQL Server 2008 DB with many tables filled with data and I used SQL Server Management Studio to generate a SQL dump by using the Script Wizard : Tasks -> Generate Scripts -> Script All objects in the selected database and also selecting the option to Script Data. I made sure to change the value of "Script for Server Version" to "SQL Server 2008". Then I created a new DB and ran the SQL dump on the new DB to generate an identical copy of the old DB. Then I assigned permissions to my default user to the new DB. Then I changed the connection string on my ASP.NET application to use the new DB. But when I run it, it throws the following exception -
Server Error in '/myapp' Application. The 'System.Web.Security.SqlMembershipProvider' requires a database schema compatible with schema version '1'. However, the current database schema is not compatible with this version. You may need to either install a compatible schema with aspnet_regsql.exe (available in the framework installation directory), or upgrade the provider to a newer version.

Well it's finally time to stop ignoring my unit's need for reports. I keep coming to dead ends. I gave up the crystal reports idea, and ssrs seems a little easier. Now the problem is that I'm creating a report locally on my laptop, then will change the connection string, upload it to my server and have it run against an identical database on the server.
I'm using SQL Server Express locally, and when I try to create a dataset (using the wizard), I can see the tables, but when I try to add one, I get an error message "Could not retrieve schema information for table or view". I looked up this error and there isn't much useful info on it. I guess it some bug when trying to use SS Express? Is there a work around for this? Can I create the report programmatically? Should I use a different kind of reporting service?
When I created table on the shared SQL server on hosting server using management studio, I right click mouse on the table, it pops up create table. However, the table schema is my user name but not dbo. I wnat to create table with dbo schema.
View 2 RepliesI have a Gridview connected to an Access database using a Datasource and a query SELECT * FROM [Staff]. In order to update the grid view I have to do it in the IDE and click Refresh Schema. I have tried:
StaffList.SelectCommand = "SELECT * FROM [Staff]"
StaffList.UpdateCommand = "SELECT * FROM [Staff]"
StaffList.DataBind()
Staff.DataBind()
At runtime I want it to update the Gridview.
StaffList.SelectCommand = "SELECT * FROM [Staff]"
I am building a little app to upload a picture and various downloads for different file types for the photos, but I also need be able to select the catergory they will go into. So I have two tables one that stores the catergory names and one that holds the paths to the photos and downloads the tables are related through the catergoryID.
What I need is those catergories to show up in the photo's and downloads table so that when I go to upload the photos I will be able to select the categories.
I have also built the DataSet and the Business Logic.
I am using an ADO Entity Model for my ms-sql database.
My database has a Resellers table which has ResellerID (primary key, int) and Name columns along with other data.
I also have an Orders table which contains OrderID (primary key, int), OrderDate, ResellerID (foreign key to Resellers.ReselerID).
If I just do a query like:
[Code]....
I am able to reference order.Reseller.Name just fine with no problems.
However I have an EntityDataSource on my page as follows:
[Code]....
Notice the Include="Reseller" attribute in the datasource... I also have a GridView tied to that datasource as follows: I cut some of it off for breavity:
[Code]....
Now what I have listed above will run with no errors, but what I want to do is replace the column that displays "ResellerID" with the equivilant to order.Reseller.Name. In other words I want my grid to display the reseller's name rather than the numeric ID.
I have tried to change the DataField to "Reseller.Name" but that will generate the following error:
A field or property with the name 'Reseller.Name' was not found on the selected data source.
Is there anyway to do this without me writing a custom select statement in my code behind?
I want to show the textbox which is in Gridview, eventhough the Datasource[Table] of the Gridview is empty.The user has to enter some value and save it in the table. My problem, when there is no value in the table, textbox is not shown. I am using Linq, So the Gridview has to bind using Linq list or table The objective of the task:
1. Show the blank textbox when there is no data in the table.
2.A Addnew Buton has to show, If the user clicks the Addnew button, One more textbox has to shown and user can enter the second input.
I am not sure why this is happening, but when I drop a GridView on the page and set up the SqlDataSource to point to a stored procedure - when I go to refresh the schema and add my session variable, I get an "Invalid object name #temp_table_Name" I have the appropriate read permissions on the tempdb. The user and password info are correct. The temp table is created in the stored procedure before executing the query.

View 2 RepliesI have like 5-6 controllers that I need to show the same table ( got the datas from DB ).
So I got 2 questions:
- How can I use WebGrid and MVC to show 2 tables with different datas in the same view.
Because now, I use a ViewModel and then the WebGrid takes Model has his data-source.
- Is there a way to include that table in 5-6 pages. I know with PHP, i can do a Include() and the trick is done...
