I am binding ExtJs Gridpanel from database and add "Delete" button below my gridpanel. By using the delete button handler, I have deleted selected record on gridpanel. But, after deleting, the grid does not refresh (it is deleted from database but shows on grid because of no refresh).
How can I refresh grid after delete handler ?
Try refreshing the view:
Ext.getCmp('yourGridId').getView().refresh();
reload the ds to refresh grid.
ds.reload();
grid.store = store;
store.load({ params: { start: 0, limit: 20} });
grid.getView().refresh();
I had a similiar problem. All I needed to do was type store.load(); in the delete handler. There was no need to subsequently type grid.getView().refresh();.
Instead of all this you can also type store.remove(record) in the delete handler; - this ensures that the deleted record no longer shows on the grid.
try this grid.getView().refresh();
It's better to use store.remove than model.destroy.
Click handler for that button may looks like this:
destroy: function(button) {
var grid = button.up('grid');
var store = grid.getStore();
var selected = grid.getSelectionModel().getSelection();
if (selected && selected.length==1) {
store.remove(selected);
}
}
grid.getStore().reload({
callback: function(){
grid.getView().refresh();
}
});
Combination of Dasha's and MMT solutions:
Ext.getCmp('yourGridId').getView().ds.reload();
Another approach in 3.4 (don't know if this is proper Ext): You can have a delete handler like this, assuming every row has a 'delete' button.
handler: function(grid, rowIndex, colIndex) {
var rec = grid.getStore().getAt(rowIndex);
var id = rec.get('id');
// some DELETE/GET ajax callback here...
// pass in 'id' var or some key
// inside success
grid.getStore().removeAt(rowIndex);
}
Refresh Grid Store
Ext.getCmp('GridId').getStore().reload();
This will reload the grid store and get new data.

I work with extjs 3.4
I have a problem when I try to assign defaut value in combobox
this is my code :
<form:combobox property="from_tr"
displayField="fullname" valueField="id"
allowBlank="true" editable="true" forceSelection="true"
pageSize="10" hideTrigger="true" width="400"
fields="address" lang="<%=lang%>"
tpl='<tpl for="."><div class="x-combo-list-item"><b>{fullname}</b><br>{address}</div></tpl>'
dataStore="com.testStore" autoLoad="false" />
in onready function I make this code :
Ext.onReady(function() {
Ext.QuickTips.init();
var idAdr='AB-20';
var store = from_tr_myPage.getStore();
store.load({
callback: function() {
from_tr_myPage.setValue(idAdr);
}
});
});
but after test I have this value AB-20 in combobox
in the combobox I want to show the fullname
I try without success to render and reload the combobox
First of all, if you try to html with extjs component, it will unnecessary
complex. Why don't you use the combobox component which sencha is providing.
I suggest to use inbuilt component as much as possible.
Try something like that:
var index = store.find("id", idAdr);
var recordSelected = store.getAt(index);
from_tr_myPage.setValue(recordSelected.get('fullname'));
Hope this helps.
How do I reset my ExtJS filters in my grids. More specifically, how do I get the header to honour the changes to the filtering.
ie. This works fine :
grid.store.clearFilter();
But the header rendering is all wrong. I need to get into all the menu objects and unselect the checkboxes.
I am getting pretty lost. I am pretty sure this gives me the filterItems :
var filterItems = grid.filters.filters.items;
And from each of these filter items, i can get to menu items like so :
var menuItems = filter.menu.items;
But that's as far as I can get. I am expecting some kind of checkbox object inside menu items, and then I can uncheck that checkbox, and hopefully the header rendering will then change.
UPDATE :
I now have this code. The grid store has its filter cleared. Next I get the filterItems from grid.filters.filters.items and iterate over them. Then I call a function on each of the menu items.
grid.store.clearFilter();
var filterItems = grid.filters.filters.items;
for (var i = 0; i<filterItems.length; i++){
var filter = filterItems[i];
filter.menu.items.each(function(checkbox) {
if (checkbox.setChecked)
checkbox.setChecked(false, true);
});
}
The checkboxes do get called, but still nothing is happening :(
Try this code:
grid.filters.clearFilters();
This should take care of both the grid and its underlying store.
When you do
grid.store.clearFilter();
it can only clear the filters on the store but the grid's view doesn't get updated with that call. Hence to handle it automatically for both the grid's view as well as the grid's store, just use
grid.filters.clearFilters();
Hope it helps!
Cheers!
Your update help me but you forget the case where you have input text instead of checkbox.
So this is my addition of your solution:
grid.filters.clearFilters();
var filterItems = grid.filters.filters.items;
for (var i = 0; i<filterItems.length; i++){
var filter = filterItems[i];
filter.menu.items.each(function(element) {
if (element.setChecked) {
element.setChecked(false, true);
}
if(typeof element.getValue !== "undefined" && element.getValue() !== "") {
element.setValue("");
}
});
}
When you use grid wiht gridfilters plugin
and inovoke
grid.filters.clearFilters();
it reset applyed filters, but it don't clean value in textfield inside menu.
For clean textfield text you can try this:
grid.filters.clearFilters();
const plugin = grid.getPlugin('gridfilters');
let activeFilter;
if('activeFilterMenuItem' in plugin) {
activeFilter = plugin.activeFilterMenuItem.activeFilter
}
if (activeFilter && activeFilter.type === "string") {
activeFilter.setValue("");
}
Im having trouble with the clear filter.
I have a button called filter_clear and I want to do is that it should remove all the filtered data in my datagrid, here is my code
filter_clear:function(button){
console.log("Clear Filter");
var store = grid.getStore();
// clear any fliters that have been applied
store.clearFilter( true );
// load the store
store.load();
},
but its not working, any ideas? thanks in advance :D
I have two grids; I call them child and parent grid. When I add a new row(data) into the parent grid, I want to reload the parent grid. I was trying to edit it using the afteredit function in the code. If I uncomment out line number 2 in the alert, that works fine. But with out the alert, the newly added row is hidden. I don't understand what's going wrong in my code. Please can anyone tell me what to do after I add the new row in to my grid and how to reload the grid immediately?
this my afteredit function
afteredit : function (roweditor, changes, record, rowIndex)
{ //alert('alert me');
if (!roweditor.initialized) {
roweditor.initFields();
}
var fields = roweditor.items.items;
// Disable key fields if its not a new row
Ext.each(fields, function (field, i) {
field.setReadOnly(false);
field.removeClass('x-item-disabled');
});
this.grid.getSelectionModel().selectRow(0);
this.grid.getView().refresh();
},
xt.ux.grid.woerp =
{
configRowEditor:
{
saveText: "Save",
cancelText: "Cancel",
commitChangesText: WOERP.constants.gridCommitChanges,
errorText: 'Errors',
listeners:
{
beforeedit: WOERP.grid.handler.beforeedit,
validateedit: WOERP.grid.handler.validateedit,
canceledit: WOERP.grid.handler.canceledit,
afteredit: WOERP.grid.handler.afteredit,
aftershow: WOERP.grid.handler.aftershow,
move: WOERP.grid.handler.resize,
hide: function (p)
{
var mainBody = this.grid.getView().mainBody;
if (typeof mainBody != 'undefined')
{
var lastRow = Ext.fly(this.grid.getView().getRow(this.grid.getStore().getCount() - 1));
if (lastRow != null)
{
mainBody.setHeight(lastRow.getBottom() - mainBody.getTop(),
{
callback: function ()
{
mainBody.setHeight('auto');
}
});
}
}
},
afterlayout: WOERP.grid.handler.resize
}
},
AFAIK RowEditor is a plugin for GridPanel which changes underlying data which comes from store. Usually updates are also made by store. If you want to know when data is saved, you should attach event handler to store. Example:
grid.getStore().on('save', function(){ [...] });
Finally i found solution. When i add reload function in to the afteredit method that will be hide newly added row. So Grid reload After commit data in to that data grid store work well for me. Anyway thanks lot all the people who try to help
this my code look like
record.commit();
grid.getView().refresh();
I think there exist a Save button after editing grid.
So in the handler of Save you can catch the event
or using
Ext.getCmp('your_saveButtonId').on('click', function(component, e) {
// Here they will be checking for modified records and sending them to backend to save.
// So here also you can catch save event
}
I have a grid on my panel, named gridView, and gridView is in panel named panelMain, by dbclick listener on grid row, I load a from by doing something like this:
listeners:{
itemdblclick: function(dataview, index, item, e) {
/* I did not create new studentForm every time.*/
var editStudent = Ext.getCmp('editStudent');
if(editStudent == undefined)
editStudent = Ext.create('H.view.EditStudent');
editStudent.getForm().load({
url: 'studentDetails.php',
params: {studentId: studentId},
method:'GET',
success: function (form, action) {
var panelMain = Ext.getCmp('panelMain');
panelMain.items.clear();
panelMain.add(editStudent);
panelMain.update();
panelMain.doLayout();
},
failure: function (form, action) {
/// do nothing
}
});
}
After I edited the student I should come back to grid page, so I do something like this:
var panelMain = Ext.getCmp('panelMain');
var gridView = Ext.getCmp('gridView');
panelMain.items.clear();
panelMain.add(gridView);
panelMain.update();
panelMain.doLayout();
The problem is when I come back to the grid, it does not fire any itemdbclick event any more (it's like the grid is just an image in page, no event fires).
And sometimes when I go to edit studentForm and come back grid work, but when I go to student form again, the student page does not fire any event, when I click edit button, I do not get any answer, I cant see even on mouse hover (that causes changes on button color).
What is the problem here?
I use Extjs 4 and Extjs MVC.
I have one Controller for grid and edit student page.
I think your misunderstand the success config on form.
Try:
listeners:{
itemdblclick: function ( gridView, record, item, index, e, eOpts ) {
var editStudent = Ext.getCmp('editStudent');
if(editStudent == undefined)
editStudent = Ext.create('H.view.EditStudent');
/* Load record in the form.
Form must have on formfields property: 'name' equals to 'dataIndex' */
editStudent.getForm().loadRecord(record);
var panelMain = Ext.getCmp('panelMain');
panelMain.items.clear();
panelMain.add(editStudent);
}
success and failure are the callbacks functions for the submit function.
a) You are not using MVC pattern here. With what Sencha calls MVC, you would have all this code in a Controller instead of event listener.
b) I strongly suspect that this code causes deadlocks somewhere, with events firing so rapidly in succession that browser just freezes. You need to use debugger to see what exactly happens.
