DataSource Controls :: SQL Datasource Commands Not Working On Hosted Pages?

Dec 1, 2010

im explaining this base on a test page that i have hosted as i was trying to track down my problem, i have a hosted page which i have hosted on the internet on a hosting service provider. the page has a normal gridview that is linked to a SqlDataSource. and theSqlDataSource has sql statements for selecting data, updating and deleting. They all work fine locally and even if i host them locally through IIS. but on the hosting service they down work. only the select work, which means i can view my data on the gridview but i cant manipulate it, delete and updating dont wanna work, they dont do anything. and the worse part is that im not even getting an error from them, on the grid i have enabled the autogenerate edit button and the delete, how can i make the update and delete work, or what is it that makes them not to work. the code for my test page is below

DataSource Controls :: LINQ To SQL SubmitChanges() Not Working Sometimes?

I was trying to delete records from database and sometimes on production, the SubmitChanges() goes through and updates the associated entities yet the data does not gets deleted in the database.This is happening only in production and I could not replicate the same on stage or on my local machine. Now the table in which I am performing the delete transaction does have primary keys.

DataSource Controls :: Update Record Not Working?

Jun 17, 2010

I am not sure if I am in the right spot here because this really doesn't have to do any datacontrol but hopefully somone can give me a hand with this.

Basically I have a bunch of TextBox controls on a page that are displaying the data I want but when I try to run an UPDATE query on the record I get nothing. The record values don't update and I don't appear to get any exceptions.....I am actually kinda really baffled on this one, here is what I have for the update code: [Code]....

Btw, if there is an easier way to do this with a control I am up for suggestions as I am just going off of some of my old VB6 ways

DataSource Controls :: SqlDataSource Query Not Working?

Feb 18, 2011

I have a strange problem...I am programatically adding an SQL SELECT query to my SqlDataSource that my GridView is bound to. If I use the follwing statement it works fine:

But if I use the following one, the gridview fails to load. The only way that this is different is it uses RTRIM and CAST on one of the fields:

I don't understand why this can be. If I try the statement exactly how it is in the query builder and run it it returns the rows no problem.

DataSource Controls :: Update Table Not Working?

Jun 3, 2010

I have a sproc that updates data in the table but I'm having difilulties with one of the params that is of type datetime. In the sproc, a decision is made based on this date such as if the date is null/blank/emplty, update data, else delete data. I've tried things like

if(@Date_returned IS NOT NULL)

if(NOT @Date_returned = '')

if(@Date_returned = '')

if(@Date_returned > '01/01/0001')

but it always defaults to the "else" part where it deletes my data. The date is passed to the sproc from a .net calendar form object via a bll/dal and I can track the variable with its value. When I actually pick a date it has the date I've picked, otherwise it has a devault value of "01/01/0001 ....".

How should ckeck for this condition?

DataSource Controls :: Sql Server Update Password Not Working

Jun 4, 2010

The users of my webapplication are validated using database connection. This requires each user is a sql server database user. While logging their validity is checking by trying to create a connection using userid and password entered by the user. If connection opens successfully, it is a valid user. I also have a page in application to change the password, where sp_password is used to updated database password.

string connectionString = ConfigurationManager.AppSettings["DBServerName"];
//try to create a new connection dynamically using user id and password
connectionString = connectionString + User ID=" + userId + ";Password=" + password;
using (SqlConnection connection = new SqlConnection(connectionString))
{
connection.Open();
}

The problem is after i change password, and logout and try to login, i am able to login using old passwd also. The line of code which creates and open connection succeeds with both old and new password. If i stop and run the application again this works.

DataSource Controls :: Removing Whitespace In String Not Working?

Jan 20, 2010

I am accumulating a string for a SQL IN clause, so the format needs to be WHERE var IN ('string1','string2','string3',etc)

The strings are coming from a multiline textbox where they are pasted in from the user (one per line).

For some reason, I always get a space right after the tick and before the value in every value after the first. For instance my DataReader is only returning one record because the input string turns out like this:

SELECT * FROM Table
WHERE ID IN ('12345',' 23456',' 34567')

Here is how I am processing the string, and I can't see why it is not taking that space out.

[Code]....

Even if I move the replace space (line 2) to the end of the code block, it still wont trim it out...
