I am new to ag-grid. I am trying to add custom column menu item.
I wrote this in constructor:
this.gridOptions = <GridOptions>{
getMainMenuItems: this.addColumnMenu
};
So, Whenever I click filter icon of column, 'addColumnMenu' is called.
Now, in addColumnMenu, I have added my menu item as
var menuItems = params.defaultItems.slice(0);
menuItems.push({
name: 'Stats', action: this.callStat }
});
Its giving this.callStat is not defined. Because I am not getting anything in this
Whats wrong here ?
If addColumnMenu needs to access 'this', then it needs to be bound. One way to achieve this:
this.gridOptions = <GridOptions>{
getMainMenuItems: this.addColumnMenu.bind(this)
};

We have an Ag-Grid table with row selection via the built in checkbox functionality. The check boxes are conditionally displaying via the isRowSelectable options:
isRowSelectable: function (rowNode) {
return rowNode.data ? rowNode.data.published === false : true;
}
The published column is being updated as part of a modal called from another column. A redrawRows is being called when the modal is closed:
modal.result.then(() => {
const row = params.api.getDisplayedRowAtIndex(params.rowIndex as number);
//this.gridApi?.redrawRows([row] as any);
this.gridApi?.redrawRows();
});
The display values in the row are being updated when the modal is closed, however, the checkbox is not appearing when the published value is set to false. If I hang a breakpoint in Dev Tools the isRowSelectable code does not appear to be hit.
Any suggestions would be much appreciated.
Cheers,

Can you try this and see if it works?
let itemsToUpdate = [];
let data = rowNode.data;
// modify data fields
// Ex: data.field1 = "new value";
itemsToUpdate.push(data);
this.gridApi.applyTransaction({update: itemsToUpdate});

Use refreshCells
this.gridApi?.refreshCells({force:true});

I'm using a kendo grid and have a checkbox column with the following template:
"<input class='gridCheckbox' id='gridCheckbox_#=name#' name='Selected' type='checkbox' ng-model='dataItem.checked'/>"
In addition I'm also using an observableArray as the grid's dataSource.
When clicking the chekcbox the data in the observableArray is changed as expected but no "change" event is triggered.
Here is how I define the observableArray:
var obsArray = new kendo.data.ObservableArray(scope.gridData);
this.gridDataSource = new kendo.data.DataSource({
data: obsArray
});
obsArray.bind("change", function (e) {
console.log(e.action, e.field);
});
"scope.gridData" is the original dataModel. When I click the checkbox the observableArray is changed but not the "scope.gridData". In order to change the "scope.gridData" I want to listen to the "change" event and change the "scope.gridData" manually but as I said the "change" event is not triggered.
Any suggestions to what am I doing wrong and maybe there is a better solution.
Read This
your issue is that kendo uses a copy of your scope object
I manually added an event to my input checkbox (in our class we're using Angular so it was on ng-click="doSomething()" but maybe yours is just click="doSomething" and recorded handling the boolean change manually.
We have the Kendo Observables, too - but I got **lucky because we're also using the Breeze JS stuff where we can do data detection and refresh the grid once the data propagates backwards to the right place to be set to dirty. ( grid.dataSource.read(); )
If you want the full row value, make the click="doSomething(this)" and then capture it as the Sender. Just debug in and you should the dataItem attached to the Sender.
This might help you & this is not the correct figure but i did one example like this similar to your problem
var contentData = [
{ organization: 'Nihilent', os: 'Window' }
];
var nihl = contentData[0];
var viewModel = kendo.observable({
gridSource: new kendo.contentData.DataSource({
contentData: contentData
})
});
kendo.bind($(document.body), viewModel);
contentData.push({ organization: 'Dhuaan', os: 'Android' });
nihl.set('os', 'iOS');
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("");
}
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.
I need help with a script to add an "active" class to a div when a hidden checkbox is checked. This all happening within a somewhat complex form that can be saved and later edited. Here's the process:
I have a series of hidden checkboxes that are checked when a visible DIV is clicked. Thanks to a few people, especially Dimitar Christoff from previous posts here, I have a few simple scripts that handle everything:
A person clicks on a div:
<div class="thumb left prodata" data-id="7"> yadda yadda </div>
An active class is added to the div:
$$('.thumb').addEvent('click', function(){
this.toggleClass('tactive');
});
The corresponding checkbox is checked:
document.getElements("a.add_app").addEvents({
click: function(e) {
if (e.target.get("tag") != 'input') {
var checkbox = document.id("field_select_p" + this.get("data-id"));
checkbox.set("checked", !checkbox.get("checked"));
}
}
});
Now, I need a fourth ( and final ) function to complete the project (using mootools or just plain javascript, no jQuery). When the form is loaded after being saved, I need a way to add the active class back to the corresponding div. Basically reverse the process. I AM trying to figure it out myself, and would love to post an idea but anything I've tried is, well, bad. I thought I'd at least get this question posted while I work on it. Thanks in advance!
window.addEvents({
load: function(){
if (checkbox.checked){
document.getElements('.thumb').fireEvent('click');
}
}
});
Example: http://jsfiddle.net/vCH9n/
Okay, in case anyone is interested, here is the final solution. What this does is: Create a click event for a DIV class to toggle an active class onclick, and also correlates each DIV to a checkbox using a data-id="X" that = the checkbox ID. Finally, if the form is reloaded ( in this case the form can be saved and edited later ) the final piece of javascript then sees what checkboxes are checked on page load and triggers the active class for the DIV.
To see it all in action, check it out here: https://www.worklabs.ca/2/add-new/add-new?itemetype=website ( script is currently working on the third tab, CHOOSE STYLE ). You won't be able to save/edit it unless you're a member however, but it works:) You can unhide the checkboxes using firebug and toggle the checkboxes yourself to see.
window.addEvent('domready', function() {
// apply the psuedo event to some elements
$$('.thumb').addEvent('click', function() {
this.toggleClass('tactive');
});
$$('.cbox').addEvent('click', function() {
var checkboxes= $$('.cbox');
for(i=1; i<=checkboxes.length; i++){
if(checkboxes[i-1].checked){
if($('c_'+checkboxes[i-1].id))
$('c_'+checkboxes[i-1].id).set("class", "thumb tactive");
}
else{
if($('c_'+checkboxes[i-1].id))
$('c_'+checkboxes[i-1].id).set("class", "thumb");
}
}
});
// Add the active class to the corresponding div when a checkbox is checked onLoad... basic idea:
var checkboxes= $$('.cbox');
for(i=1; i<=checkboxes.length; i++){
if(checkboxes[i-1].checked){
$('c_field_tmp_'+i).set("class", "thumb tactive");
}
}
document.getElements("div.thumb").addEvents({
click: function(e) {
if (e.target.get("tag") != 'input') {
var checkbox = document.id("field_tmp_" + this.get("data-id"));
checkbox.set("checked", !checkbox.get("checked"));
}
}
});
});
