You already have an empty component in your HTML page. If Flexmonster Component is not embedded – return to Quickstart. Your code should look like the following example:
<div id="pivotContainer">The component will appear here</div>
<script src="flexmonster/flexmonster.js"></script>
<script>
var pivot = new Flexmonster({
container: "pivotContainer",
toolbar: true,
licenseKey: "XXXX-XXXX-XXXX-XXXX-XXXX"
});
</script>
First of all, you need to add the following dependencies to your project:
Flexmonster.Compressor.dll – it is located in Pivot Table for Databases/server/.net/ folder of your downloaded package.Below is the connection and query sample for MS SQL Server:
string connectionString = "Server=localhost;Database=XXX;"; SqlConnection sqlConnection = new SqlConnection(connectionString); sqlConnection.Open(); string query = "SELECT * FROM YYY"; DbCommand command = new SqlCommand(query, sqlConnection); DbDataReader reader = command.ExecuteReader();
The following line of code will convert DbDataReader to compressed Stream:
Stream inputStream = Flexmonster.Compressor.CompressDb(reader);
Now, you can create a response from the Stream. For simple cases, it is enough to read all content:
string output = new StreamReader(inputStream).ReadToEnd();
Also, it is possible to create streaming response. It means that the end user will get the response almost without delay and server will use less amount of memory. It is recommended way for large datasets:
HttpResponseMessage response = Request.CreateResponse();
response.Content =
new PushStreamContent((Stream outputStream, HttpContent content,
TransportContext context) =>
{
int length = 0;
byte[] buffer = new byte[10240];
while ((count = inputStream.Read(buffer, 0, buffer.Length)) > 0)
{
outputStream.Write(buffer, 0, length);
outputStream.Flush();
}
outputStream.Close();
}, new MediaTypeHeaderValue("text/plain")
);
The full project is available at the Pivot Table for Databases/server/.net/ inside download package.
By default, browser prevents JavaScript from making requests across domain boundaries. CORS allows web applications to make cross-domain requests. Here are some useful links explaining how to setup CORS on your server:
Now it’s time to configure Flexmonster Pivot Component on the web page. Let’s create a minimal report for this (replace filename and other parameters with your specific values):
var pivot = new Flexmonster({
container: "pivotContainer",
toolbar: true,
report: {
dataSource: {
dataSourceType: "ocsv",
/* URL to the Data Compressor .NET */
filename: "http://localhost:55772/api/flexmonster/get"
}
},
licenseKey: "XXXX-XXXX-XXXX-XXXX-XXXX"
});
Launch the web page from browser — here you go! A pivot table is embedded into your project. Check the example on JSFiddle.
string connectionString = "Server=localhost;Database=XXX;";
SqlConnection sqlConnection = new SqlConnection(connectionString);
sqlConnection.Open();
string query = "SELECT * FROM YYY";
DbCommand command = new SqlCommand(query, sqlConnection);
DbDataReader reader = command.ExecuteReader();
Stream inputStream = Flexmonster.Compressor.CompressDb(reader);
FileStream fileStream = File.Create("data.ocsv");
inputStream.CopyTo(fileStream);
fileStream.Close();
