I am quite stuck. I have my database running on a seperate machine from where I am writing my application. The connection between Visual Studio and the database seems to be fine as I can display data in various controls on the GUI.

My problem arises when I try to add something to the database, I get no error messages just the data isn't added to the database.

Here is my code:

MyDataSet.categoryRow newRow = myDataSet.category.NewcategoryRow();

newRow.CategoryID = Convert.ToInt32(tbxID.Text);
newRow.CategoryName = tbxCategory.Text;
newRow.Description = tbxDescription.Text;

categoryDA.Update(fYPDataSet); //categoryDA is the table adapter generated by visual studio

I have tried many variations on this in attempt to get it to work.
Including the following:

System.Data.SqlClient.SqlConnection con;
System.Data.SqlClient.SqlDataAdapter da;

con = new System.Data.SqlClient.SqlConnection();

con.ConnectionString = "Data Source=FYPSERVER;Initial Catalog=FYP;Integrated Security=True";


string sql = "SELECT * from category";
da = new System.Data.SqlClient.SqlDataAdapter(sql, con);

System.Data.SqlClient.SqlCommandBuilder cb;
cb = new System.Data.SqlClient.SqlCommandBuilder(da);
MyDataSet.categoryRow newRow = myDataSet.category.NewcategoryRow();

newRow[1] = tbxCategory.Text;
newRow[2] = tbxDescription.Text;

da.Update(myDataSet, "catagory");

I also added a dataGridView control and linked that to the deisred table, using the design window, not through code.
Even when I add, edit or remove any of the values none of it is happening to the actual database or when I close and re-open that particular form.

I apologise if there has been some disucssion of this before but I have been working on this one aspect for a week and I am beginning to loose the will to live. I have done a search for this issue but all the results I have come across are due to error messages.

I am writing this in Visual Studio 2010 ultimate and the database is running under SQL Server 2008 R2 Enterprise

Thank you very much

Here is my simple code to save the record in table.

cnn.ConnectionString = "your connection string";
cmd.CommandText = "select * from <tablename>";
cmd.Connection = cnn;
da.SelectCommand = cmd;
da.Fill(ds, "<tablename>");

OleDbCommandBuilder cmb = new OleDbCommandBuilder(da);
DataRow drow;
drow = ds.Tables["table1"].NewRow();

drow["column1"] = textBox1.Text;
drow["column2"] = textBox2.Text;
drow["column3"] = textBox3.Text;

da.Update(ds, "table1");
MessageBox.Show("ONE RECORD IS ADDED.");

ds dataset
da data adapter
table1 name of your table
column1,column2.column3 is the name of column in your table
cmd is a command object

I hope it will help you other wise feel free to ask any problem

That was perfect.

Thank you very much
