Scrollbar location is wrong in layout : fit

I have a Panel and in that panel I am loading grid dynamically.
Here is code for panel
{
xtype: 'panel',
region: 'center',
frame: true,
scrollable: true,
itemId: 'MyGrid',
reference: 'MyGrid',
layout: {
type: 'vbox',
align: 'stretch'
},
items: []
}
and Sample of grid.
Ext.define("MyApp.view.MYGrid", {
extend: 'Ext.grid.Panel',
alias: 'widget.MyGrid',
requires: [
'Ext.grid.filters.Filters',
'Ext.form.field.ComboBox',
],
emptyText: 'No data available.',
disableSelection: true,
margin: '3 3 0 3',
collapsible: true,
multiSelect: false,
closable: true,
columnLines: true,
uniqueFields: [],
});
initComponent: function() {
var me = this;
me.fields = me.prepareFields(me.headersXmlDoc);
me.columns = me.prepareColumns(me.headersXmlDoc);
me.store = me.prepareGridStore(me.headersXmlDoc);
this.callParent(arguments);
},
Now when Grid have enough data then both horizental and vertical scroll is coming correctly but When grid have less data with more columns scrollbar is coming down. I supposed just beow the last record but it comming in down.
All the grid is taking same height though it have a less record.

I want scrollbar just below the last data. By debugging I found layout : fit
But not sure how to overcome out from that.
Can anybody help me that. Thanks for help.

You need to apply overflowY as true for grid.I don't think there is some problem with fit layout.If above config doesn't work share some fiddle.

Column layout in EXTJS

I am new to ExtJs. I need to create an entry form in 2 columns using column layout.
My code is as follows:
Ext.onReady(function(){
var patientForm = new Ext.FormPanel({
renderTo: "patientCreation",
frame: true,
title: 'Search Criteria',
labelAlign: 'left',
labelStyle: 'font-weight:bold;',
labelWidth: 85,
width: 900,
items: [
{
layout:'column',
items:[
{ // column #1
columnWidth: .33,
layout: 'form',
items: [
{ xtype: 'textfield',
fieldLabel: 'FirstName',
name: 'firstName',
vtype : 'alpha',
allowBlank:false
},{
xtype: 'textfield',
fieldLabel: 'MiddleName',
name: 'middleName',
vtype : 'alpha'
}
] // close items for first column
}]
}]
});
var win = new Ext.Window({
layout:'form',
closable: false,
resizable: false,
plain: true,
border: false,
items: [patientForm]
});
win.show();
});
But when I run the code, I got h is undefined error. How to design a form in column layout? Is there any procedure, steps or links which give a clear idea?

I have run the same code with ExtJs 3.2.2 and got a similar error. But when I removed renderTo: "patientCreation"
code worked:
That part is not necessary 'cause you are placing the form in a the window.

I do not know anything about ExtJS 3. If you are using ExtJS 4, then you have specified layout config at wrong place. You have specified it inside items config, it should not be inside items config.
Layout can be specified as follows in ExtJS 4:
Ext.define('your_domain_name.viewName', {
extend : 'Ext.panel.Panel',
alias : 'widget.any_name_you_want',
layout : 'column',
initComponent : function() {
this.items = [
// all items inside form/panel will go here
];
this.callParent(arguments);
}
});
You can get sample code about all the panels here

try applying renderTo config to window instead of form

Getting Model from GridPanel in ExtJS

I have a gridpanel that allows inline editing of a column. This column uses a combobox as the editor, and neither the "change" event nor the "select" event give me something usable to backtrace the edited value to get the changed row from the gridpanel.
I believe Ext floats the editor's combobox so therefore I can't do something simple like
combo.up()
To return to the grid.
Here is the grid panel from the view:
{
xtype: 'gridpanel',
title: 'Important Projects',
id: 'importantProjectsGrid',
dockedItems: [],
flex: 1,
columns: [
{ header: 'Quote Name', dataIndex: 'QuoteName', flex: 4 },
{ header: 'Quote Status', dataIndex: 'QuoteStatusID', flex: 6, editor: {
xtype: 'combobox',
editable: false,
action: 'QuoteStatus',
selectOnTab: true,
store: 'statuses',
queryMode: 'local',
displayField: 'Description',
valueField: 'Description'
} }
],
store: 'myimpprojects',
selModel: {
selType: 'cellmodel'
},
plugins: [Ext.create('Ext.grid.plugin.CellEditing', {
clicksToEdit: 1
})]
}
Here is the controller code pertaining to this:
init: function () {
this.control({
'[action=QuoteStatus]': {
change: function (combo, new_value, old_value, opts) {
// I need to go back up from this combobox
// to get the row that this value was edited in
// to grab an ID value from that row's data
// in order to make an ajax request
}
}
});
},
Thanks for any help!

You can monitor store's update event.
init: function () {
this.getMyimpprojectsStore().on('update', function(store, record) {
// do something with record
});
// ...
},

Try putting the listener on the CellEditing plugin. There are events for beforeedit, edit, and validateedit that receive an object containing references to the grid, the record, field, row and column indexes, and more. You should be able to check for the combobox in the event handler and handle your information from there.
Quick link to the doc page: Ext.grid.plugin.CellEditing

I'm convinced that the update plugin will handle the update automatically, through the api of the underlying store and post the data automatically to the server if the proxy as autoSync to true.
Example of the configured proxy:
Ext.define('MyApp.store.YourStore', {
extend: 'Ext.data.Store',
model: 'MyApp.model.YourGridModel',
autoSync: true, //Commits the changes realtime to the server
proxy: {
type: 'ajax',
batchActions : true, //Commits the changes everytime a value is changed if true o otherwise store the changes and batch update them in 1 single post
api: {
read: 'path/to/select',
create: 'path/to/create',
update: 'path/to/update',
destroy: 'path/to/delete'
},
reader: {
type: 'json',
root: 'results',
successProperty: 'success'
},
writer: {
type: 'json',
writeAllFields: true
},
listeners: {
exception: function(proxy, response, operation){
Ext.MessageBox.show({
title: 'REMOTE EXCEPTION',
msg: operation.getError(),
icon: Ext.MessageBox.ERROR,
buttons: Ext.Msg.OK
});
}
}
},
listeners: {
write: function(proxy, operation){
var response = Ext.JSON.decode(operation.response.responseText);
if(response.success == true)
{
//TODO: Proxy - Messageboxes might be a little anoying we might instead use the status bar in teh grid or something so show status of the operation
Ext.MessageBox.show({
title: this.xFileLibraryTitle,
msg: response.message,
icon: (response.success == true)? Ext.MessageBox.INFO : Ext.MessageBox.ERROR,
buttons: Ext.Msg.OK
});
}
}
}
});
I would look specially for the two configs: "autoSync" and "batchActions"
Hope this helps you further with your issue!

ExtJS ComboBox not displaying elements

I am having trouble getting a ComboBox in ExtJS to display the dropdown items. I originally was using an XmlStore to load the data dynamically, but to make sure that wasn't the problem, I took an existing ComboBox that uses a simple ArrayStore (and currently works elsewhere in my application) to see if it would work, still with no luck.
When using Chrome's developer tools, when I click on the ComboBox element, I get ext-all-debug.js:41166 - Uncaught TypeError: Cannot call method 'getStyle' of undefined and nothing shows up for a dropdown.
Here is my code:
EventForm = Ext.extend(Ext.form.FormPanel, {
constructor: function(config) {
config = Ext.apply({
items: [
{
layout: 'column',
xtype: 'container',
items: [
{
layout: 'form',
xtype: 'container',
columnWidth: 0.5,
items: [
{
fieldLabel: 'My Combo Box'
name: 'mycombobox',
xtype: 'combo',
store: new Ext.data.ArrayStore({
fields: ['size'],
data: [
['50'],
['100'],
['150'],
['200']
]
}),
displayField: 'size',
valueField: 'size',
forceSelection: true,
editable: false,
triggerAction: 'all',
mode: 'local',
listWidth: 60,
width: 60
}
]
}, {
// another column here similar to above
}
]
}
]
}, config);
EventForm.superclass.constructor(config);
}
});

You are not calling the constructor of EventForm's superclass correctly. Change the last line of your constructor function to read:
EventForm.superclass.constructor.call(this, config);

Your data array must contain a list of objects, and the keys you provided by fields must be the keys your data refers to in those objects. The correct syntax for your data array could be:
data: [
{'size':'50'},
{'size':'100'},
{'size':'150'},
{'size':'200'}
]
(could be, because I have no chance right now to verify)

Ext js FormPanel is not showing panel items when toolbar is present

I seem to be having a weird issue here. An extended component has the following code:
MyApp.panels.RelationshipDetails = Ext.extend(Ext.FormPanel, {
closable: true,
relationshipId: null,
documentId: null,
title: 'Relationship',
initComponent: function () {
if (!this.verifyRequiredData()) {
MyApp.panels.RelationshipDetails.superclass.initComponent.call(this);
return;
}
// Build components
this.tbar = this.buildToolbar();
this.items = this.buildDetailItemArray();
MyApp.panels.RelationshipDetails.superclass.initComponent.call(this);
},
verifyRequiredData: function () {
// Verification code here
},
buildDetailItemArray: function () {
return [{
xtype: 'fieldset',
title: 'Details',
collapsible: true,
autoHeight: true,
items: [{
xtype: 'hidden',
name: 'Id'
}, {
xtype: 'textfield',
fieldLabel: 'Name',
name: 'Name'
}, {
xtype: 'textfield',
fieldLabel: 'Description',
name: 'Description'
}, {
xtype: 'button',
text: 'Save',
name: 'saveButton'
}]
}];
},
buildToolbar: function () {
return new Ext.Toolbar({
// Toolbar Config
});
}
});
The issue is that when this panel renders, the toolbar is the only thing that renders. Through debugging I can see that BuildDetailItemArray() is being called correctly and returning the correct result.
It gets even weirder when I comment out the this.tbar = line, because when the toolbar is not present, the fieldset and field renders correctly. This occurs even if I extend Panel instead of FormPanel. I also tried abstracting out the form fields into it's own component, and the same thing occurs.
Anyone have any idea why this doesn't seem to work?

What sort of layout are you trying to put this panel into? Also, are you setting a height for this panel?
Often, if you aren't specifying a height for the component to be added (in your case, this panel), or you're not setting an anchor if using an AnchorLayout, component content won't be shown, but the toolbar still will.
It'd be good to know the context of this panel in your overall layout.
