Introduction to jQWidgets jqxPivotGrid pivotcellmousedown Event

The jqxPivotGrid is a powerful widget from jQWidgets that allows you to visually represent complex data in a pivot table format. One of the many events available in jqxPivotGrid is the pivotcellmousedown event.

The pivotcellmousedown event is triggered when the user clicks on a pivot cell in the pivot grid. This event provides an opportunity for developers to perform custom actions based on the user's interaction with the pivot grid.

Event Syntax

The pivotcellmousedown event has the following syntax:

$(selector).on('pivotcellmousedown', function (event) { 
   //event handler 
}); 
Event Parameters

The pivotcellmousedown event passes an event parameter to the event handler function. The event parameter provides information about the user's interaction with the pivot grid, including the cell that was clicked, the row and column indexes of the cell, and more.

$(selector).on('pivotcellmousedown', function (event) { 
   var cell = event.args.cell;
   var row = event.args.row;
   var column = event.args.column;
   // additional code here
}); 
Event Object

The event parameter passed to the pivotcellmousedown event handler function also includes an args object, which provides additional information about the cell that was clicked. The args object contains the following properties:

  • cell - the jqxPivotGridCell object representing the clicked cell.
  • row - the row index of the clicked cell.
  • column - the column index of the clicked cell.
  • originalEvent - the original browser event that triggered the pivot cell mousedown event.
Examples

Here's an example of a pivotcellmousedown event handler function that alerts the user with the text "Clicked on cell":

$(selector).on('pivotcellmousedown', function (event) { 
   alert('Clicked on cell'); 
}); 

Here's an example that shows how to get the values of the row and column indexes:

$(selector).on('pivotcellmousedown', function (event) { 
   var row = event.args.row;
   var column = event.args.column;
   alert('Clicked on cell at row index ' + row + ' and column index ' + column); 
}); 

And here's an example that shows how to get the value of the clicked cell:

$(selector).on('pivotcellmousedown', function (event) { 
   var cell = event.args.cell;
   alert('The clicked cell value is ' + cell.value); 
});

In conclusion, the pivotcellmousedown event in jQWidgets' jqxPivotGrid widget provides a powerful mechanism for developers to respond to user interactions with pivot cells in the pivot grid. The event handler function can include custom code to perform actions such as changing the appearance of the grid or updating underlying data.
