Grid Drag and Drop Question

[DavidSimmonsParticipant]

I am trying to understand the dragStart or dragEnd event to see if I can drag from the a grid and drop it into some other droppable element. (FullCalendar) One of the requirements are that the Text or Cell Text that is dropped is a eventObject defined as title: $.trim($(this).text()).

My examples are http://www.digitalconceptdesigns.com/DND/DND.php

rendered: function(type)
{
….
gridCells.jqxDragDrop({
……

//**************************
//This would be the $(‘#calendar’)
dropTarget: $(‘#grid2’), revert: true
});
…….
// initialize the dragged object.
gridCells.on(‘dragStart’, function (event) {
var value = $(this).text();
var cell = $(“#grid1”).jqxGrid(‘getcellatposition’, event.args.pageX, event.args.pageY);

//**************************
//Need to convert the cell text into a eventObject before sending like this
var eventObject = {
title: $.trim($(this).text()) // use the element’s text as the event title
};

$(this).data(‘eventObject’, eventObject);
//**************************
//I am not sure what this part is doing, can you help me understand?
$(this).jqxDragDrop(‘data’, {
value: value
});
});

// set the new cell value when the dragged cell is dropped over the second Grid.
gridCells.on(‘dragEnd’, function (event) {
//**************************
//If my calendar handles the Drop event, is this still needed? I am not sure….
var value = $(this).text();
var cell = $(“#grid2”).jqxGrid(‘getcellatposition’, event.args.pageX, event.args.pageY);
if (cell != null) {
$(“#grid2”).jqxGrid(‘setcellvalue’, cell.row, cell.column, value);
}
});
},

Using your example under grids Drag & Drop can you help under stand how I can only allow one column to be dragged from grid1 and only one column except the drop in grid2?

I would appreciate any help…

This example shows how to setup a one way drag and drop from a Grid to another Grid.

$(document).ready(function () {
var theme = getDemoTheme();
var source =
{
localdata: generatedata(100),
datafields:
[
{ name: ‘firstname’, type: ‘string’ },
{ name: ‘lastname’, type: ‘string’ },
{ name: ‘productname’, type: ‘string’ }
],
datatype: “array”
};
var dataAdapter = new $.jqx.dataAdapter(source);
// create data grids.
$(“#grid1”).jqxGrid(
{
width: 450,
source: dataAdapter,
pageable: true,
autoheight: true,
sortable: true,
rendered: function(type)
{
// select all grid cells.
var gridCells = $(‘#grid1’).find(‘.jqx-grid-cell’);
// initialize the jqxDragDrop plug-in. Set its drop target to the second Grid.
gridCells.jqxDragDrop({
appendTo: ‘body’, theme: theme, dragZIndex: 99999,
dropAction: ‘none’,
initFeedback: function (feedback) {
feedback.height(25);
},
dropTarget: $(‘#grid2’), revert: true
});
gridCells.off(‘dragEnd’);
gridCells.off(‘dragEnd’);
gridCells.off(‘dropTargetEnter’);
gridCells.off(‘dropTargetLeave’);
// disable revert when the dragged cell is over the second Grid.
gridCells.on(‘dropTargetEnter’, function () {
gridCells.jqxDragDrop({ revert: false });
});
// enable revert when the dragged cell is outside the second Grid.
gridCells.on(‘dropTargetLeave’, function () {
gridCells.jqxDragDrop({ revert: true });
});
// initialize the dragged object.
gridCells.on(‘dragStart’, function (event) {
var value = $(this).text();
var cell = $(“#grid1”).jqxGrid(‘getcellatposition’, event.args.pageX, event.args.pageY);
$(this).jqxDragDrop(‘data’, {
value: value
});
});
// set the new cell value when the dragged cell is dropped over the second Grid.
gridCells.on(‘dragEnd’, function (event) {
var value = $(this).text();
var cell = $(“#grid2”).jqxGrid(‘getcellatposition’, event.args.pageX, event.args.pageY);
if (cell != null) {
$(“#grid2”).jqxGrid(‘setcellvalue’, cell.row, cell.column, value);
}
});
},
theme: theme,
selectionmode: ‘singlecell’,
columns: [
{ text: ‘First Name’, dataField: ‘firstname’, width: 125 },
{ text: ‘Last Name’, dataField: ‘lastname’, width: 125 },
{ text: ‘Product’, dataField: ‘productname’, width: 200 }
]
});
$(“#grid2”).jqxGrid(
{
width: 450,
theme: theme,
selectionmode: ‘singlecell’,
autoheight: true,
source: { totalrecords: 10, unboundmode: true, datafields:
[
{ name: ‘firstname’ },
{ name: ‘lastname’ },
{ name: ‘productname’ }
]
},
columns: [
{ text: ‘First Name’, dataField: ‘firstname’, width: 125 },
{ text: ‘Last Name’, dataField: ‘lastname’, width: 125 },
{ text: ‘Product’, dataField: ‘productname’, width: 200 }
]

});
});

Here is my example. I am trying to find a way to only allow certain columns to be draggable and certain columns to be droppable.

I would appreciate any help…
