DataSource Controls :: Connect Gridview To Database?
Apr 21, 2010
I've created a SQL Server Express database to use with a program I'm working on in Visual Web Developer 2008. The connection works fine according to the Add connection-wizard in VWD. However there's a problem when I try to select data from the database and present the data in a gridview. The error message says that the gridview isn't connected to the database. The gridviews DataSource ID (source-mode) is the same as the name of the database. In design-mode, when I try try configure the datasource I get to a point where I have to configure the select statement, but I just want the connection to work in a way that let's me write the sql-statements in the aspx.cs-file.

I'm new here and I'm in dire need of help. Been trying to solve a problem for hours now.Here's what I wanted to do: I added a table 'tblProductCat' in the webform and I intend to populate the table with VB codes as shown below
[Code]....
What am I doing wrong here? I really can't figure this out. There was a time when, instead of that exception handling message appearing, a yellow box that states something between the lines of 'offline' and 'check your root folder for *something*' or something like that.

I'd like to connect to a database on a different domain. I've done some search and people say to add a connectin using an enterprise manager? Where can I find sql enterprise manager? On msn website, they only show things about sql enterprise manager for sql 2000. Is this a tool only included in sql 2000?

I had a database on a development server of which I am not the owner. The connection string was:
Dim MM_cnnTraining_STRING
MM_cnnTraining_STRING = "Provider=SQLOLEDB.1;Password=xxx;Persist Security Info=True;User ID=xxx;Initial Catalog=Training;Data Source=xxx"
I copied this database to my local machine, In services MSSQL is set to logon with my computer username and password, I have no idea if this affects anything.Also the local database which I can view in MSSQL Server Management Studio, I can connect by Windows Authentication only. The database copied there seems to have maintained the same permissions.Im completely confused. I finally was able to copy to my local machine but now can not connect. I am using dreamweaver, but using the connection string above.

what the ASP code is to connect to a domaincentral phpMyAdmin SQL database?They have zero online help or templates and their online help staff can't/won't assist.
I created a DSN entry and have tried various permutations of of the following:
Connection.Open "DSN=robinvi_mysql_dsn;"
including the driver, server (localhost) username and pwd strings but I still get:
[MySQL][ODBC 3.51 Driver]Can't connect to MySQL server on 'localhost' (10061)
Also, what should the DSN entry contain? Currently it is:
Server localhost (the default)
Database robinvi_test
Description Whatever...
UID robin_michael
PWD ***
Port 3306 (the default)
Option 16 (the default)

I started a new Sql Server 2008 with mixed authentication Windows and SQL SERVER AUTh... I created a new login account and use it to directly connect in SQL server managment studio BUT... when i create in VS2008 the connectionstring... everytime i try to open the DB connection i take an exception to the login... some screenshots show all the process ;)
LOGIN: admintvmaismais
PASSWORD: ex
Working to connect in SQL SERVER MANAGEMENT...
LOGIN STATUS ON SQL SERVER MANAGEMENTE
Now in VS2008 Web-Config I declare the connectionstring:
<connectionStrings>
<add name="SqlConnectionString" connectionString="Server=JP;Database=tvmaismais;User ID=admintvmaismais;Password=ex;" providerName="System.Data.SqlClient" />
</connectionStrings>
and When i try to open a connection like this:
SqlConnection conn = new SqlConnection(ConfigurationManager.ConnectionStrings["SqlConnectionString"].ConnectionString);
try
{
conn.Open();
...
}
catch (Exception e)
{
retorno = e.Message.ToString();
}
finally
{
if (conn.State == ConnectionState.Open)
conn.Close();
conn.Dispose();
}
I get this exception: Cannot open database "tvmaismais" requested by the login. The login failed. Login failed for user 'admintvmaismais'. What am I missing? What do i need to do, to get this login to work?

I'm using an ODBC connection to connect a SQL 2005 database to my ASP.NET app in Visual Web Developer Express. I'm finding that the expected functionality that tutorials review does not work for ODBC connected databases the same way as it does for SQL databases created in the Web Developer. For example, I can't use stored procedures because the option to create one is disabled in the Web Developer, and if I create the stored procedure in SQL Server Management Studio Express, it doesn't show up in Web Developer because Web Developer only finds the system stored procedures, not the user-defined ones. I've seen other cases as well where database management options in Web Developer don't work with ODBC databases.
Am I missing something in my setup, or is there an inherent limitation with ODBC connected databases? Or, is this a limitation with using the Express versions of these development tools?

I have created web pages using VS Web Developer that use a local Developer Edition of SQL server database on my PC with LINQ to SQL. When I deploy my website to a remote web host SQL server, I need for my web pages to be able to use the remote database instead of the local database. So, how do I get the Server Explorer to connect with a remote SQL Server database?

I am sure I am not the first to ask this question but I cannot find an answer in these or any other forums. I guess I am not wording the question right. In short I have a gridview populated but a database via an SQLDatasource. I have an Edit column in the datagrid and an updatequery in the datasource. When the Edit is click the line goes into edit mode, the user then clicks Update and I get an error. Could not find control 'DropDownList1' in ControlParameter 'Frequency'. The only complication is that there is a drop down control when the "EDIT" column is selected. The dropdownlist gets it list from another SQLDatasource. This all works fine. Here is the code snip:
<asp:GridView ID="GridView1" runat="server" AllowSorting="True" AutoGenerateEditButton="True"

I'm working on a web application in Visual Studio 2008. I'm using gridview to pull data from our database (I'm using a SQL Datasource) . I have a template field with a checkbox function and it allows you to check certain rows and disable them. What I am trying to do is send the enabled rows aka the non selected rows to a seperate table in our database. I'm assuming its just some kind of insert statement but I'm stuck on specifics..I am getting a object reference not sent to an instance of an object error. The line that is higlighted is, cmd.Paramters.AddWithValue("[Wrk_Pgrm_ID]" txt1.Text);
Below is the code i recieved from an earlier thread that I have modified.

I'm running SQL Express 2005 on an SBS 2003 Standard Server and I keep getting this error back.A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections. (provider: SQL Network Interfaces, error: 28 - Server doesn't support requested protocol)
I've uploaded my project to this same server, and I've so far checked that TCP/IP has been enabled for this instance, I've checked the IPs are relevant, I've checked that the connection string is correct, and I've even set a dynamic port number as I've noticed that SBS runs 2005 databases for Sharepoint and Monitoring.
Interestingly enough, I can connect to this instance via Visual Studio on my remote machine, and SSMSE and also via SSMSE on the server as well?The connection string i'm running with is:
Data Source=localhostVDSSQL;Initial Catalog=myDB;Persist Security Info=True;User ID=SA;Password=***
