I using Ext JS 2.3.0 and have a GridPanel that looks like this:
I want to expand the width of the column such that the scroll bar is pushed over the extreme right of the panel, thus eliminating the empty space to the right of the scroll bar.
The relevant code is shown below:
var colModel = new Ext.grid.ColumnModel([
{
id: 'name',
header: locale['dialogSearch.column.name'],
sortable: true,
dataIndex: 'name'
}
]);
var selModel = new Ext.grid.RowSelectionModel({singleSelect: false});
this._searchResultsPanel = new Ext.grid.GridPanel({
title: locale['dialogSearch.results.name'],
height: 400,
layout: 'fit',
stripeRows: true,
autoExpandColumn: 'name',
store: this._searchResultsStore,
view: new Ext.grid.GridView(),
colModel: colModel,
selModel: selModel,
hidden: true,
buttonAlign: 'center',
buttons: [
{
text: locale["dialogSearch.button.add"],
width: 50,
handler: function () {
}
},
{
text: locale["dialogSearch.button.cancel"],
width: 50,
handler: function () {
entitySearchWindow.close();
}
}
]
});
You should use the forceFit config for the grid view:
this._searchResultsPanel = new Ext.grid.GridPanel({
title: locale['dialogSearch.results.name'],
height: 400,
layout: 'fit',
viewConfig: {
forceFit: true
}, ....
I'm not sure if this isn't redundant so you can remove this part view: new Ext.grid.GridView(),
The problem is not the column but the grid itself which does not stretch to fill the window body completely.
Put the layout: 'fit' property onto the window config instead of onto the grid config (where it needs to be removed). You should also remove the height property because the grid height will determined by the window's size.
Add
flex: 1,
to one of the the columns config

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.
I'm struggling mightily to get the height of an ExtJS panel and the only reason I can think it's any different is that it's the panel defined as a border region, because I've not had this problem otherwise (maybe I need to report a bug to them). I'll begin with some code that demonstrates how I'm trying to get the height, with results demonstrating what the height really is, what ExtJS says it is, and how it's not an issue with a panel using a different layout (one of the panels inside the border region):
'cmBuildTab #cmProductExplorer': {
afterrender: function(productExplorer) {
var domNode = Ext.getDom(productExplorer.el),
savedSearchesPanel = productExplorer.down('#savedSearchesPanel');
console.log('productExplorer.getHeight(): ' + productExplorer.getHeight());
console.log(productExplorer.componentLayout);
console.log(productExplorer.componentLayout.lastComponentSize);
console.log(domNode);
console.log('domNode.style.height: ' + domNode.style.height);
console.log('savedSearchesPanel.getHeight(): ' + savedSearchesPanel.getHeight());
}
},
I was initally encouraged I might have a couple of alternate ways to get the height, via the dom node, or via componentLayout.lastComponentSize but neither of these are accessible to Javascript code, only the chrome console. My final try then would be to parse the returned dom string but that is a horrible hack. Suggestions appreciated; below the console.log results is the pertinent portion of my view config.
console.log results:

afterrender is not the event you want to use to determine the heights of components, it fires when the elements have been rendered not after they have been sized. If you are using 4.1 you can use the boxready event which fires only once the the container is intially sized http://docs.sencha.com/ext-js/4-1/#!/api/Ext.AbstractComponent-event-boxready . If not you can use the afterlayout event to determine size but that event fires every layout.
Also fyi widths as percentages are not documented as supported in 4.0, I've seen them work and I've seen them fail.
Here is some code I hijacked from the Viewport example thanks to a court ruling this is ok.
4.1
Ext.create('Ext.container.Viewport', {
layout: 'border',
items: [{
region: 'north',
html: '<h1 class="x-panel-header">Page Title</h1>',
border: false,
margins: '0 0 5 0'
}, {
region: 'west',
collapsible: true,
title: 'Navigation',
width: 150,
//ADD LISTENERS
listeners: {
afterrender:function(){console.log( 'afterrender ' +this.getHeight())},
boxready:function(){console.log( 'boxready ' +this.getHeight())}
}
// could use a TreePanel or AccordionLayout for navigational items
}, {
region: 'south',
title: 'South Panel',
collapsible: true,
html: 'Information goes here',
split: true,
height: 100,
minHeight: 100
}, {
region: 'east',
title: 'East Panel',
collapsible: true,
split: true,
width: 150
}, {
region: 'center',
xtype: 'tabpanel', // TabPanel itself has no title
activeTab: 0, // First tab active by default
items: {
title: 'Default Tab',
html: 'The first tab\'s content. Others may be added dynamically'
}
}]
});
Output :

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

I'm having trouble getting a panel to fill the space within its container panel. The container is a panel with a vbox layout having two child panels. I looked at Extjs how to set 100% height for vbox panel
and have something similar but it doesn't seem to work.
Screenshots:-
http://i.imgur.com/nAbCr.png
The screenshot is from when i use a 'fit' layout or dont even have the combobox or optionsview in a containing panel. So, what i want is for the 'options' panel to extend all the way down till the 'results' panel.
with the present vbox layout this is what i get - http://i.imgur.com/cB0k1.png
Ext.define('PA.view.CreateReportView', {
extend: 'Ext.panel.Panel',
alias: 'widget.createreportview',
id: 'createreport-panel',
requires: [
'PA.view.OptionsView', // options panel
'PA.common.Connection'],
title: 'Create Report',
items: [{
xtype: 'panel',
layout: {
type: 'vbox',
align: 'stretch'
},
items: [{
xtype: 'panel',
border: false,
height: '50px',
items: [{
xtype: 'combobox',
....
}]
}, {
xtype: 'panel',
border: false,
flex: 1,
items: [{
xtype: 'optionsview', // options panel
style: {
paddingTop: '10px'
}
}]
}]
}]
});
The value of height: should be a number, not a string. So use height: 50 instead.
I think you have it close to what you need. Couple of observations:
1. Heights need to be set as integers (no px suffix)
2. Each container that will have children should have a layout defined for them, even though there is default - it might not be what you want.
Here is your layout working reasonably well http://jsfiddle.net/dbrin/NJjhB/
One other suggestion I would add is to use a tool like Illuminations for Developers - a firebug plugin that knows about ExtJS framework.
I'm facing a dilemma working with an Ext-JS GridPanel: the data used to load its store is dynamic so I don't know beforehand how many rows will need to be shown on the grid.
As such, I'm having a hard time with the grid's height: I've tried setting autoHeight to true but the grid will only display the first row, hiding the rest; when I set its height explicitly, white space appears on the grid if the number of rows doesn't fill the space specified by the height.
Ideally, the grid should expand/shrink vertically to show all of its rows.
Is there any way to make the grid's height dynamic, based on the number of rows it'll contain?
I could wait for the grid to render, get a count of rows and recalculate the grid's height based on that but it seems hacky and I'm looking for something cleaner.
This is my code for reference:
var store = new Ext.data.ArrayStore({fields:[{name: 'sign_up_date'}, {name: 'business_name'}, {name: 'owner_name'}, {name: 'status'}]});
// buildResultsArray is a method that returns arrays of varying lengths based on some business logic. The arrays can contain no elements or up to 15
store.loadData(buildResultsArray());
var resultsGrid = new Ext.grid.GridPanel({
store: store,
columns: [
{id: "sign_up_date", header: "Sign Up Date", dataIndex: "sign_up_date", width: 70},
{id: "business_name", header: "Business Name", dataIndex: "business_name", width: 100},
{id: "owner_name",header: "Owner Name", dataIndex: "owner_name", width: 100},
{id: "status", header: "Sign Up Status", dataIndex: "status", width: 70}
],
stripeRows: true,
columnLines: true,
enableColumnHide: false,
enableColumnMove: false,
enableHdMenu: false,
id: "results_grid",
renderTo: "results_grid_div",
//height: 300,
autoHeight: true,
selModel: new Ext.grid.RowSelectionModel({singleSelect: false})
});
Thanks for the help.
In ExtJS 3 it's not working out-of-box, but it's easy to implement by extending GridView:
AutoGridView = Ext.extend(
Ext.grid.GridView,
{
fixOverflow: function() {
if (this.grid.autoHeight === true || this.autoHeight === true){
Ext.get(this.innerHd).setStyle("float", "none");
this.scroller.setStyle("overflow-x", this.scroller.getWidth() < this.mainBody.getWidth() ? "scroll" : "auto");
}
},
layout: function () {
AutoGridView.superclass.layout.call(this);
this.fixOverflow();
},
render: function(){
AutoGridView.superclass.render.apply(this, arguments);
this.scroller.on('resize', this.fixOverflow, this);
if (this.grid.autoHeight === true || this.autoHeight === true){
this.grid.getStore().on('datachanged', function(){
if (this.ownerCt) { this.ownerCt.doLayout(); }
}, this.grid, { delay: 10 });
}
}
}
);
Usage:
new Ext.grid.GridPanel({
autoHeight: true,
view: new AutoGridView()
});
