Hi,

I am trying to implement the Grid Drag and Drop functionality as per the below example.

http://docs.sencha.com/ext-js/4-0/#!/example/dd/dnd_grid_to_grid.html

Example works, but i have to drag and drop in between 4 grids, i have to drag from one grid and drop in any of the other 3 grids.
Is that even possible?
i tried to do some trial and errors but not successful. if i drop in one grid it is adding the record to all the grids.

Thanks
srikanth

Do you have a unique store for each grid? The drop simple updates the underlying store.

Yes, i have unique stores for all the grids and they have unique storeId's. and all the stores are having a common model

Here is the example in mention with 3 grids:



// GRID; DRAG; DROP; MULTIGRID;

Ext.define('DataObject', {
extend: 'Ext.data.Model',
fields: ['name', 'column1', 'column2']
});

Ext.onReady(function(){

var myData = [
{ name : "Rec 0", column1 : "0", column2 : "0" },
{ name : "Rec 1", column1 : "1", column2 : "1" },
{ name : "Rec 2", column1 : "2", column2 : "2" },
{ name : "Rec 3", column1 : "3", column2 : "3" },
{ name : "Rec 4", column1 : "4", column2 : "4" },
{ name : "Rec 5", column1 : "5", column2 : "5" },
{ name : "Rec 6", column1 : "6", column2 : "6" },
{ name : "Rec 7", column1 : "7", column2 : "7" },
{ name : "Rec 8", column1 : "8", column2 : "8" },
{ name : "Rec 9", column1 : "9", column2 : "9" }
];

// create the data store
var firstGridStore = Ext.create('Ext.data.Store', {
model: 'DataObject',
data: myData
});


// Column Model shortcut array
var columns = [
{text: "Record Name", flex: 1, sortable: true, dataIndex: 'name'},
{text: "column1", width: 70, sortable: true, dataIndex: 'column1'},
{text: "column2", width: 70, sortable: true, dataIndex: 'column2'}
];

// declare the source Grid
var firstGrid = Ext.create('Ext.grid.Panel', {
multiSelect: true,
viewConfig: {
plugins: {
ptype: 'gridviewdragdrop',
dragGroup: 'firstGridDDGroup',
dropGroup: 'secondGridDDGroup'
},
listeners: {
drop: function(node, data, dropRec, dropPosition) {
var dropOn = dropRec ? ' ' + dropPosition + ' ' + dropRec.get('name') : ' on empty view';
//Ext.example.msg("Drag from right to left", 'Dropped ' + data.records[0].get('name') + dropOn);
}
}
},
store : firstGridStore,
columns : columns,
stripeRows : true,
title : 'First Grid',
margins : '0 2 0 0'
});

var secondGridStore = Ext.create('Ext.data.Store', {
model: 'DataObject'
});

// create the destination Grid
var secondGrid = Ext.create('Ext.grid.Panel', {
viewConfig: {
plugins: {
ptype: 'gridviewdragdrop',
dragGroup: 'secondGridDDGroup',
dropGroup: 'firstGridDDGroup'
},
listeners: {
drop: function(node, data, dropRec, dropPosition) {
var dropOn = dropRec ? ' ' + dropPosition + ' ' + dropRec.get('name') : ' on empty view';
//Ext.example.msg("Drag from left to right", 'Dropped ' + data.records[0].get('name') + dropOn);
}
}
},
store : secondGridStore,
columns : columns,
stripeRows : true,
title : 'Second Grid',
margins : '0 0 0 3'
});

var thirdGridStore = Ext.create('Ext.data.Store', {
model: 'DataObject'
});

// create the destination Grid
var thirdGrid = Ext.create('Ext.grid.Panel', {
viewConfig: {
plugins: {
ptype: 'gridviewdragdrop',
dragGroup: 'thirdGridDDGroup',
dropGroup: 'firstGridDDGroup'
},
listeners: {
drop: function(node, data, dropRec, dropPosition) {
var dropOn = dropRec ? ' ' + dropPosition + ' ' + dropRec.get('name') : ' on empty view';
//Ext.example.msg("Drag from left to right", 'Dropped ' + data.records[0].get('name') + dropOn);
}
}
},
store : thirdGridStore,
columns : columns,
stripeRows : true,
title : 'third Grid',
margins : '0 0 0 3'
});

//Simple 'border layout' panel to house both grids
var displayPanel = Ext.create('Ext.Panel', {
width : 850,
height : 300,
layout : {
type: 'hbox',
align: 'stretch',
padding: 5
},
renderTo : Ext.getBody(),
defaults : { flex : 1 }, //auto stretch
items : [
firstGrid,
secondGrid,
thirdGrid
],
dockedItems: {
xtype: 'toolbar',
dock: 'bottom',
items: ['->', // Fill
{
text: 'Reset both grids',
handler: function(){
//refresh source grid
firstGridStore.loadData(myData);

//purge destination grid
secondGridStore.removeAll();

//purge destination grid
thirdGridStore.removeAll();
}
}]
}
});
});

its working for me, the issue was with the mix up with id's

mix up with id's

A good reason (lesson) for not using id's .. use itemId instead.
