How to change styling of cells that has been edited in ag-Grid?

I want to mark cells who has been edited so the user can see which cells have been touched and altered. I know there is a cell flash option, but that just changes the background colors for a bit. What I want is a background color change when an edit has been done.
Cannot seem to find any specific documentation on accessing for example the html element or the styling of affected cell.
Anyone got any ideas?

You can use ColDef.onCellValueChanged to detect if something changes and update the cell style accordingly using GridApi.refreshCells()
const columnDefs = [{
headerName: "Athlete",
field: "athlete",
onCellValueChanged: this.markAsDirty
},...]
...
private markAsDirty(params: ICellRendererParams) {
params.colDef.cellClass = (p) =>
p.rowIndex.toString() === params.node.id ? "ag-cell-dirty" : "";
params.api.refreshCells({
columns: [params.column.getId()],
rowNodes: [params.node],
force: true // without this line, the cell style is not refreshed at the first time
});
}
In your css file
:host ::ng-deep .ag-cell-dirty {
background-color: rgba(255, 193, 7, 0.5) !important;
}
You may also want to use defaultColDef if you want this behavior applied to all columns
this.gridOptions = {
defaultColDef: {
editable: true,
onCellValueChanged: this.markAsDirty
},
};
Live Demo

I did this on a project I was working on.
There is a cellClass property that you can define in your column definitions (https://www.ag-grid.com/javascript-grid-cell-styles/) and it can take a callback function with params: CellClassParams.
So try doing:
cellClass: (params: CellClassParams) => {
// you need to have a handle on the original untouched data
// See if the original value does not equal the modified value in params
// For shortness, I will write pseudocode
if (originalValue !== modifiedValue) {
return 'ag-cell-was-modified';
}
}
If many columns are editable, you may want to use a re-usable function for cellClass for each column.
That should apply the class ag-cell-was-modified conditionally whether the cell was modified or not and in your style.scss or main stylesheet, you can add:
.ag-cell-was-modified {
background: red;
}
Of course, if you are using SASS, you can place this class definition in somewhere more appropriate.

Non editable kendo grid ID

I'm new using kendo grid UI, i'm trying to make a non editable column (when updating) using a simple code :
schema: {
id: 'ID',
fields: {
id: { editable: false }
}
}
This default schema, makes by default non editable id column, and i can't even create a new row with id .
I want to make it non editable (when updating) but i want the possibility to create a row and assign an id from user (when creating).
Any ideas ?
Edit :
PS : the proprety is not related to only id, it can be on every column (can't update but can create)

The editable required a function instead of a value.
columns: [
{ field: 'value', editable: function () { return false; } }
],
Checkout here:
https://dojo.telerik.com/oROJayAd

I always doubt about that model editable option. It never really worked for me. It should have something very deep in the setup to make it work which I never realized what it. So this is a way to acomplish what you need that I know it indeed works: To cancel the edit event. Check it out:
edit: function(e) {
// Cancels a new row
if (arguments, e.model.isNew()) {
this.cancelRow(e.container.parent());
}
else { // Cancels a cell editing
this.closeCell(e.container);
}
}
Demo
Now, if you like to add a condition in that event based on what you have set in your model, you can access it within event as well:
edit: function(e) {
let currentColumn = this.options.columns[e.container.index()].field,
model = this.dataSource.options.schema.model.fields[currentColumn];
if (model.editable === false) {
// Cancels a new row
if (arguments, e.model.isNew()) {
this.cancelRow(e.container.parent());
}
else { // Cancels a cell editing
this.closeCell(e.container);
}
}
}
Demo
You can add an option yourself in the model to set if the column can be updated or only created, and handle that information inside the event, canceling the editing whenever you like.

This is how I just did it, though there are other ways.
In columns option if you remove the field option from a column it doesn't know from where to bind it.
Then use the template option to show(bind) the id. Thus making it readonly
columns: [
{
title: 'Id', width: "40px",
template: "#= id #",
},
...]

How to add a customize buttons in dojox grid?

I've developed web applications with Dojo for more than one year, and I've used dojox grid a lot, but there is no way to add customize buttons on DataGrid or EnhancedGrid, as I know that ExtJS, or EasyUI, jQuery jqgrid are capable doing this.
So I want to ask if there is any way that can add buttons or other HTML DOM in the dojox.DataGrid?

at least, you can add dojo.form.Button's to it. simly add an element to the structure-property of your DataGrid like that (sorry, due to no-time i just copy pasted it from an actual project of mine...):
{
name: ' ',
field: 'idx',
type: dojox.grid.cells._Widget,
editable: false,
formatter: function (idx) {
return new dijit.form.Button({
_destroyOnRemove: true,
label: 'Bearbeiten',
onClick: function () {
dojo.byId('clickedItemIdx').value = idx + '';
if (reports.entries[idx].type == 'Rufbereitschaft') {
dojo.byId('addOrEditEntry_OCD_btn').click();
} else {
dojo.byId('addOrEditEntry_ASS_btn').click();
}
}
});
}
},
note that my data contains an idx-field which i commit to the onclick-function in order to know which element was clicked. This is the only way i got this to work.
As you may know, you can add multiple of those structure-elements referring to the same field.

ExtJS display RowExpander on condition only

I currently have a rather big Grid and am successfully using the RowExpander plugin to display complementary informations on certain rows. My problem is that it's not all rows that contain the aforementioned complementary informations and I do not wish the RowExpander to be active nor to show it's "+" icon if a particular data store's entry is empty. I tried using the conventional "renderer" property on the RowExpander object, but it did not work.
So basically, how can you have the RowExpander's icon and double click shown and activated only if a certain data store's field != ""?
Thanks in advance! =)
EDIT: I found a solution
As e-zinc stated it, part of the solution (for me at least) was to provide a custom renderer that would check my conditional field. Here is my RowExpander:
this.rowExpander = new Ext.ux.grid.RowExpander({
tpl: ...
renderer: function(v, p, record) {
if (record.get('listeRetourChaqueJour') != "") {
p.cellAttr = 'rowspan="2"';
return '<div class="x-grid3-row-expander"></div>';
} else {
p.id = '';
return ' ';
}
},
expandOnEnter: false,
expandOnDblClick: false
});
Now, the trick here is that for this particular Grid, I chose not to allow the expandOnEnter and expanOnDblClick since the RowExpander will sometimes not be rendered. Also, the CSS class of the grid cell that will hold the "+" icon is 'x-grid3-td-expander'. This is caused by the fact that the CSS class is automatically set to x-grid3-td-[id-of-column]. So, by setting the id to '' only when I'm not rendering the rowExpander, I'm also removing the gray background of the un-rendered cells. So, no double click, no enter, no icon, no gray-background. It really becomes as if there is strictly no RowExpander involved for the columns where my data store field is empty (when I want no RowExpander).
That did the trick for me. For someone that wishes to preserve the ID of the cell, or that wishes to keep the double click and enter events working, there is nothing else to do other than extending the class I guess. Hope this can help other people stuck in the position I was!

p.id = '';
return ' ';
}
},
expandOnEnter: false,
expandOnDblClick: false
});
Now, the trick here is that for this particular Grid, I chose not to allow the expandOnEnter and expandOnDblClick specifically since the RowExpander will sometimes not be rendered. Also, the CSS class of the grid cell that will hold the "+" icon is 'x-grid3-td-expander'. This is caused by the fact that the CSS class is automatically set to x-grid3-td-[id-of-column]. So, by setting the id to an empty string only when I'm not rendering the rowExpander, I'm also removing the gray background of the cells that won't offer any expanding. So, no double click, no enter, no icon, no gray-background. It really becomes as if there is strictly no RowExpander involved for the columns where my data store field is empty (when I want no RowExpander).
That did the trick for me. For someone that wishes to preserve the ID of the cell, or that wishes to keep the double click and enter events working, there is nothing else to do other than extending the RowExpander class in my opinion. Of course, one could also use Ext.override(), but then all instances of RowExpander would be hit by the override.

I have the same task, there is my solution
var rowExpander = new Ext.ux.grid.RowExpander({
renderer : function(v, p, record){
return record.get('relatedPageCount') > 0 ? '<div class="x-grid3-row-expander"> </div>' : ' ';
}
});
I have overridden render method which test relatedPageCount field in store and render + or white space.

I think I've found a cleaner solution.Give me a feedback pls :)
I extend the toggleRow method of RowExpander and if I match a condition avoid to toggle the row.Otherwise the standard flow continues
Ext.create('customplugins.grid.plugin.ClickRowExpander',{
pluginId : 'rowexpander',
rowBodyTpl : new Ext.XTemplate(
'<p><b>Last Modified By:</b> {usermodify}</p>',
'<p><b>User data:</b> {userdata}</p>',
'<p><b>Correlation ID:</b> {correlationid}</p>',
'<p><b>Description:</b> {descr}</p>'
),
toggleRow : function(rowIdx, record) {
if(record.get('directory')) return false;
customplugins.grid.plugin.ClickRowExpander.prototype.toggleRow.apply(this, arguments);
}
})

This version works in Ext JS 5 and 6 (classic)
One thing is to remove the +/- icon, which can be done via grid viewConfig:
getRowClass: function (record, rowIndex, rowParams, store) {
var yourFieldofChoice = record.get('yourFieldofChoice');
if (yourFieldofChoice == null) {
return 'hide-row-expander';
}
},
Define css for hide-row-expander:
.hide-row-expander .x-grid-row-expander {
visibility: hidden;
}
Now you disable expanding on enter key ('expandOnEnter' config is no longer supported in Ext JS 6) or double click by overriding toggleRow, or if you do not wish the override you create your custom rowexpander built on existing plugin:
Ext.define('RowExpander', {
extend: 'Ext.grid.plugin.RowExpander',
alias: 'plugin.myExpander',
init: function (grid) {
var me = this;
me.grid = grid;
me.callParent(arguments);
},
requiredFields: ['yourFieldofChoice'],
hasRequiredFields: function (rec) {
var valid = false;
Ext.each(this.requiredFields, function (field) {
if (!Ext.isEmpty(rec.get(field))) {
valid = true;
}
});
return valid;
},
toggleRow: function (rowIdx, record) {
var me = this, rec;
rec = Ext.isNumeric(rowIdx)? me.view.getStore().getAt(rowIdx) : me.view.getRecord(rowIdx);
if (me.hasRequiredFields(rec)) {
me.callParent(arguments);
}
}
});

I have handled the beforeexpand event inside the listeners of Ext.ux.grid.RowExpander. beforeexpand method got the whole row data injected. Checking the data conditionally we can return true or false. If we return false it wont expand otherwise it will do.
var expander = new Ext.ux.grid.RowExpander({
tpl: '<div class="ux-row-expander"></div>',
listeners: {
beforeexpand : function(expander, record, body, rowIndex){
var gpdata = record.data.GROUP_VALUES[1].COLUMN_VALUE
if(gpdata == null){
return false;
}
else{
return true;
}
}
}
});

In ExtJS, how to add a custom CSS class to data grid rows?

How do I add custom CSS classes to rows in a data grid (Ext.grid.Panel)?
I'm using ExtJS 4.0.

The way to do it is to define viewConfig on the grid:
Ext.create('Ext.grid.Panel', {
...
viewConfig: {
getRowClass: function(record, index, rowParams, store) {
return record.get('someattr') === 'somevalue') ? 'someclass' : '';
}
},
...
});

In your initComponent() of your Ext.grid.Panel use getRowClass() as follows:
initComponent: function(){
var me = this;
me.callParent(arguments);
me.getView().getRowClass = function(record, rowIndex, rowParams, store) {
if (/* some check here based on the input */) {
return 'myRowClass';
}
};
}
This basically overrides the getRowClass() function of the underlying Ext.grid.View which is called at render time to apply any custom classes. Then your custom css file would contain something like:
.myRowClass .x-grid-cell {background:#FF0000; }

You could do something like this:
Ext.fly(myGrid.getView().getRow(0)).addClass('myClass');
Of course you could substitute the getRow() call for another cell, or you could loop through all of your rows and add it appropriately.
And then you could style that in addition to the default CSS, by doing:
.x-grid3-row-selected .myClass {
background-color: blue !important;
}
There is also a private method of GridView called addRowClass. You can use this to add a class to your rows as well by doing:
grid.getView().addRowClass(rowId, 'myClass');
// private - use getRowClass to apply custom row classes
addRowClass : function(rowId, cls) {
var row = this.getRow(rowId);
if (row) {
this.fly(row).addClass(cls);
}
},

Use simplest way
In your grid use -
cls: 'myRowClass'
Your css -
.myRowClass .x-grid-cell {background:#FF0000 !important; }

If you want to change the class after the data has loaded, you can do it like this:
myGridPanel.getView().removeRowCls(rowIndex,"old class");
myGridPanel.getView().addRowCls(rowIndex,"new class");
Here, rowIndex is the selected row, which you can get in some event functions(like "select"). By using this, you can change CSS of the row after clicking it.
