I have some labels in my silverlight application, and I want to get data from SQL server for this label text.
How can I do that?

Something's like this with C#:

mySqlConnection = new SqlConnection(ConnectionString);

			SqlDataReader myReader = null;
			
			string sql = "select isnull(sum(Quantity),0) Quantity from Inventory where [Type] = 'Primary'";
			
			string sql2 = "select isnull(sum(Quantity),0) Quantity from Inventory where [Type] = 'Secondary'";
			
			

			SqlCommand mySqlCommand = new SqlCommand(sql + ";" + sql2, mySqlConnection);

			try
			{
				mySqlConnection.Open();
				myReader = mySqlCommand.ExecuteReader();

				while (myReader.Read())
				{
					RemainingPrimary.Text = myReader["Quantity"].ToString();
				}
				
					myReader.NextResult();
				 while (myReader.Read())
				{
					RemainingSecondary.Text = myReader["Quantity"].ToString();
				}
			}
			
			catch (Exception ex)
			{
				MessageBox.Show("Can't Get Data" + ex.Message);

			}
			finally
			{
				if (myReader != null)
					myReader.Close();
				if (mySqlConnection.State == ConnectionState.Open)
					mySqlConnection.Close();
			}

At first glance, everything looks OK. Are you getting an exception?
