How to add/remove columns and rows dynamically?

Ravi asked on May 13, 2019

Hi Team,
I’m a Premium licensed user.
 
We’re in need of adding/removing both columns and rows dynamically in pivot grid ?

  • Should input-data for these columns/rows at runtime.
  • This newly created columns should also apply pivot functionalities like format, filters etc.,
  • Also, to enable edit-mode for the existing columns/rows. 
     
    How can we achieve this?. Please guide via an fiddle sample.

Hello, Ravi,
 
 
Thank you for writing to us.
 
 
The described functionality can be achieved in the following way:
 
 
1. Adding a new field (column)
 
A new field can be added via the getReport() and setReport() API calls:

// 1. Get new column name:
var columnName = "New Data";

// 2. Get new column name data type:
var columnType = "string";

// 3. Get the current report object:
var report = pivot.getReport();

// 4. Get the data object from the report:
var currentData = report.dataSource.data;

// 5. Add the new column to the meta object of currentData:
(currentData[0])[columnName] = {"type": columnType};

// 6. Update the report:
report.dataSource.data = currentData;

pivot.setReport(report);

 
 
2. Adding new record (row)
 
A new record can be added via the updateData() API call:

var dataForUpdate = [{
"Category": "Cars",
"Price": 51844,
"RowId": 4
}]
flexmonster.updateData({data: dataForUpdate}, {partial: true});

 
 
An important remark is that the newly created columns will apply pivot functionalities like format, filters, etc. by default.
 
 
3. Enabling edit-mode for columns/rows
 
This can be achieved by setting the editing parameter in the options object to true:

options: {
editing: true
}

This way data can be edited in the drill-through pop-up window and in flat form for CSV, OCSV, and JSON data sources.
The user will be able to double-click the cell and enter a new value into it.
 
We have prepared a JSFiddle example for illustration.
 
 
Please let us know if everything works and if you have any questions.
 
We are looking forward to hearing from you.
 
 
Best Regards,
Vera
