DataSource Controls :: Generated Update Difference Between Prod And Dev?
Mar 2, 2010
I have a simple datatable with 2 fields, one a primary key which I will call PK and other which I will call COL1. I have used the dataset designer to generate update/insert/delete methods on the tableadapter. On my development system two update methods are generated wit hthe follow signatures:
Update(PK as System.String, COL1 as System.Bool, Original_PK as System.String)
Update(COL1 as System.Bool, Original_PK as System.String)
On the production system, however, the latter signature is not generated. What is more preplexing is that prior to today, production operated similar to test. Obviously somethign changed, but I have been unable to identify what.
Unfortunately the method being used now is the latter. Now I can create my own method with a similar signature, but this problem isn't unique to this datatable/tableadapter. I am very hesitent to make thsi change throughout the application, and even more so in touching the several other applications which I fear may have similar issues (though those rely less on generated udpates).
In a database table, let's say I have a non-null field named "Description" with a default value of (''). If I drag this table onto the .dbml view in Visual Studio and click on the Description field, the properties will indicate that the Auto Generated Value is set to false, thus ignoring my default value of (''). This is fine, as long as I always explicitly set a value for Description when I perform an insert/update, but I ran into a problem today when I tried to do an insert without specifying a value for Description: Cannot insert NULL value into Description. The default value I set for the field was being ignored. To try and fix this error, I went back into the .dbml and set Auto Generated Value to true, and tried again - no error this time, but the data I tried to insert was ignored, and the default value, (''), was inserted instead. I do not want to explicitly set every field to a default value programmatically when I perform inserts. Is there any other way to resolve this issue other than making the fields nullable?
MVCThe generated ADO.NET Entity Data Model loses ordinal positions of columns and reorders Entity Set column names alphabetically. This causes the columns in a new MVC VIEW to appear alphabetically and needs to be reordered by hand. I am using MySQL Database.
How can I retain the ordinal positions of columns?

I am new to LINQ. when we drag tables we get a dbml file and designer file.
For example DataClasses1.dbml and DataClasses1.designer.cs.
Once we have them then we can start using our LINQ Queries.
In my company project I do not see this designer files and instead there are .tt files which were used as templates to greate ABC.generated.cs files. Is this same as designer class?
I setup paging in GridView and it works oK in VS2005 locally but does not show when I move the page to prod server. I use masterpage, so GridView in in the Content placeholder...
I'm new to this community and got newbie question, briefly in data access in asp.net what is the difference between accessing dataset using typed Dataset and using data sources controls like SQL data source control ...? As I noticed that using data source controls is much easier, but it allows only one data access method i.e. only one query... am I right with that....
Im trying to update my DB(DataBase) by using SQL UPDATE query ,but its not updating in the dataBase i receive confirmation(in testLabel) that one row is affected(dataReader = query.ExecuteReader(); return numbers of rows affected)...
I have given a HTML editortext control on a page,which generates HTML (i have to store it in my DB,that page is only for Admin) ,on pressing Update button , im receving in my testLabel that one row is affected(which shows DB is updated succesfully) but when i check my DB its in old state,it is not updating...
Here is my Event handler of Update Button which have to make updates in DB:
After the SubmitChanges call, the Text field in data2 wasn't changed. According to the NerdDinner sample, I supposedly can just write to my data object and then call SubmitChanges.
I have an update / insert statements. If the user selects the checkbox IsPrestigeFeatured, I want that row to be set to 1 and I want all other rows to be set to 0. E.g. so there is only one row which is "Is prestige Featured"
I have a dynamically generated image placed inside an update panel. The image is generated with the Generated Image control (see here for more:
[URL]. This is basically a specialised httphandler linked to a normal asp:image, where the image src is generated dynamically. In my case, I use some GDI+ to dynamically generate the image, based on values from a database query.
The problem I have is that the image does not update when the update panel updates. The image does, however, update if I manually reload/refresh the page (i.e., hit F5). Why is is that some code fires during an update panel update, and not other code? And, more importantly, what can I do to make sure the image generation code does fire during the updatepanel update?
And in another page i am displaying the list of all the dynamic database tables. Here user selects table from gridview and the data is displayed to him in dynamically generated HTML Table with Dynamic textboxes. (This part is also running ok)
Code:
// Display data protected void getTableInfo() { int RowNo = 0; string NotCmd = "Select * From NTL Where InfoCode = @InfoCode";
[Code] ....
Now the problem is how to update the record in database through this dynamically generated html table and texboxes. When I run my dynamically generated update command, all the dynamic controls is lost in postback.
My company is interested in using C# to build their intranet website. I am searching around to find out what software we might need and how much they cost.his website http://www.asp.net/downloads/ mentioned the following software is free. anyone know if these are free for development only or both dev and prod?
