Sqlconnection(string) has some invalid arguments. I get a tooltip error for SqlConnection sql = new SqlConnection(constring) SqlCommand comm = new SqlCommand("Insert into categories (categoryName) values ('" + tb_database.Text + "')", sql) SqlConnection sql = new SqlConnection(constring) The value of Address takes precedence over the value passed to Server in ODBC connection strings when using SQL Server Native Client. rootwebconfig = .OpenWebConfiguration("/Mohtisham") If you specify an IP address, make sure that the TCP/IP or named pipes protocols are enabled in SQL Server Configuration Manager. Then add the server’s name and also the name of the database: 5. Make sure it is the same connection string that you use in your ASP application. Click on Add to configure a new connection string: 4. Once connected, click on Connection Strings: 3. protected void buttontb_click(object sender, EventArgs e) Open IIS Manager and connect to your site: 2.
WEB CONFIG SQL SERVER CONNECTION STRING CODE
However I am not able to access the connection string in my code behind. I have specified the connection string to my NorthWind database in my web.config file. SqlDataSource Wizard simply uses the same design-time services that Visual Studio exposes to all designers, so we are consistent with this inconsistency as well.I am learning to write into a database from a textbox with the click of a button. For instance, you can experience exactly the same inconsistent behavior if you add a typed DataSet and choose to store the connection string in the configuration file.
WEB CONFIG SQL SERVER CONNECTION STRING WINDOWS
Regarding the fact that connection strings for Windows applications and class libraries are stored in the ttings file as well as the App.config file, while for web applications the connection strings are stored only in the Web.config file - this inconsistency is caused by Visual Studio which treats different project types differently (not to mention web sites which are not treated as projects in Visual Studio at all). For example, the database used for development and testing purposes might be a local one, while the actual production database might be situated on a dedicated database server. Moreover this behavior allows you to use two different databases for development and for production. This is done for a reason: since a solution may contain many different projects, each of them with its own configuration file, it is unknown which one might contain the correct connection string for your report, so we simply pick the configuration file of the current project where the report is located. If you have your connection string specified in the Web.config file of another project, you need to copy it to the App.config file of the report class library as well, otherwise the wizard cannot discover it. For example, if you have a separate class library project for your reports, the wizard searches for connection strings only in the App.config file of that project. SqlDataSource Wizard searches for existing database connections in Server Explorer and in the configuration file of the current project. The database definitely isn't going down either as it is running on my local box.Īny ideas on what might cause this? I also tried an ObjectDataSource (using my LinqToSql objects) and in the code-behind of the report set the data source of that to a linq query but it won't run it (it was setup in the constructor). I know the connection strings themselves aren't an issue as I created a new project, copied from the "old" web.config to the new one and they show up in the wizard and everything functions great. I've confirmed the connection string it created is in the web.config but it still acts like it can't find it. At that point it tells me it can't connect to the DB because the connection name may be incorrect. When I let the wizard create a new connection entry (which is identical to the existing one) the report generates until I add a table and link it to the data source (which it created). When I try to create a new SQL data source the connection strings box lists all of my connections that show up in Server Explorer, but it won't list anything in my web.config. The report itself is part of an existing web project (not in a separate library) where an existing web.config has connection strings specified. I am attempting to build a report with the Q2 2011 reporting tools but am running into numerous issues that are really confusing me.
