How to use my own json object

Hi,
I'm newer !
I started using Simulsoft - Reports.js demo and I saw that you use a Json object Demo. (see the image in attachments)
I want to import my own Json object in a different file for example not "Demo.JS" but "myObject.js"
How can I import it and use it in a .mrt file ?

Hello, PaPy.
How are you running your project, from local file or Webserver?
Thank you.

Hi, Kubekin Yuriy.
I am running my project from Webserver using localhost.
I just found by myself how to do, but I had to modify by myself the .mrt file. That is not very "user friendly"...
Is it possible to give a list of different JSON objects to my clients in the "Data Sources" list to allow them to just drag and drop some datas to the report ?

I don't know if I'm clear.
I want to add a database into the .mrt file using javaScript.
For example for the following code (this is a part of my .mrt file) :
Code: Select all
"Dictionary":{
"DataSources":{
"0":{
"Ident":"StiDataTableSource",
"Name":"databases",
"Alias":"databases",
"Columns":{
"0":{
"Name":"libelle",
"Index":-1,
"NameInSource":"libelle",
"Alias":"libelle",
"Type":"System.String"
},
"1":{
"Name":"libcourt",
"Index":-1,
"NameInSource":"libcourt",
"Alias":"libcourt",
"Type":"System.String"
},
"2":{
"Name":"name",
"Index":-1,
"NameInSource":"name",
"Alias":"name",
"Type":"System.String"
}
},
"NameInSource":"datas.databases"
}
This is a table databases with 3 columns :
- libelle ;
- libcourt ;
- name.
And the datas are in a Json object called datas.databases.
Here is the value of the var datas :
Code: Select all
var datas = { "databases" : [{"libelle":"myLibelle1","libcourt":"myLibCourt1","name":"name1"},{"libelle":"myLibelle2","libcourt":"myLibCourt2","name":"name2"}]}
I want to know if is it possible to add databases using javaScript as for example :
Code: Select all
var myObj1 = {JSON};
var myObj2 = {JSON};
var myObj3 = {JSON};
var report = new Stimulsoft.Report.StiReport();
report.loadFile("test.mrt");
report.dictionary.datasources.add(myObj1);
report.dictionary.datasources.add(myObj2);
report.dictionary.datasources.add(myObj3);
report.render();
I have already tried :
Code: Select all
var datas = { "databases" : [{"libelle":"myLibelle1","libcourt":"myLibCourt1","name":"name1"},{"libelle":"myLibelle2","libcourt":"myLibCourt2","name":"name2"}]};
var dataSet = new Stimulsoft.System.Data.DataSet("datas");
var report = new Stimulsoft.Report.StiReport();
report.loadFile("test.mrt");
dataSet.readJson(datas);
report.regData(dataSet.dataSetName, "", dataSet);
report.render();
But it works only if the json object is already defined in the .mrt file. So
what is the syntax I have to used to defined my json object in the .mrt file ?

Hello,
You can provide your data to the report before running the designer with RegData() method:
dataSet.readJson(datas);
report.regData(dataSet.dataSetName, "", dataSet);
report.dictionary.synchronize();

Thank you.

- Here is what the customer should see if the .mrt file do not have dataSources defined, this should be added by javaScript before render the report.

Thanks for the answer.
But I already tried this. It works only if in my .mrt file I have defined an object datas. But imagine my report is an empty .mrt, without Databases defined.
What I want, is something like the picture in attachment. That is to say a .mrt file without data sources on wich I add my datas Sources using javaScript to have this view.
Because when I try
Code: Select all
dataSet.readJson(datas);
report.regData(dataSet.dataSetName, "", dataSet);
report.dictionary.synchronize();
It works only if my data source is defined in my .mrt file.

My bad,
I thought about add a new JSON databases but it's useless because I have already one I just have to add new tables. I think that's why it didn't working.
Thanks for your help ! That was exactly what I needed. I had misunderstand how works .mrt files and the importance of the
report.dictionary.synchronize(); which was not in this page :

Sorry.
