I'm using AgGridReact, but this is a general question about how to get the entire row's data inside a cell in that row using AgGrid.
I'm using a custom cell renderer for a certain cell (whose field is id) in which I need to get the entire row's data and not just the id field's data.
This is how the grid is defined:
<AgGridReact
rowData={users}
frameworkComponents={{
idRenderer: IdRenderer,
}}
>
<AgGridColumn field="id" cellRenderer="idRenderer"></AgGridColumn>
<AgGridColumn field="name"></AgGridColumn>
<AgGridColumn field="phone"></AgGridColumn>
<AgGridColumn field="email"></AgGridColumn>
</AgGridReact>
Here's the IdRender component (used to customize the look of the id field's cell) where I need to get the row's data:
import { useEffect } from 'react';
function IdRenderer(props) {
// the following currently stores the cell's value in `rowData`
const rowData = props.valueFormatted ? props.valueFormatted : props.value;
useEffect(() => {
console.log(rowData); // get the entire row's data here instead of just this cell's value
}, [])
return (
<>
{/* some components */}
</>
);
}
export default IdRenderer;
I'm not able to figure out from the docs what should I add to the grid or the cell renderer to be able to get the entire row's data inside the id field's cell (where I'll be posting the data to an API on a button click).
After digging through the docs for a long time I finally found the way to achieve this: using a valueGetter. I decided to post this Q&A to help others in figuring out how to achieve the same.
Just define the following value getter for the row's data:
const rowDataGetter = function (params) {
return params.data;
};
and use it on the AgGridColumn by setting the valueGetter prop:
<AgGridColumn field="id" cellRenderer="idRenderer" valueGetter={rowDataGetter}></AgGridColumn>
Now rowData in IdRenderer will contain the entire row's data instead of the cell value.

I need to update the value of one of the cells in a row in ag-grid as soon as the onCellEditingStopped callback is called (this happens when a user exits any other cell on that row).
I have this code which is based on the single cell update example at Ag grid single cell update
onCellEditingStopped: {function(event) {
event.node.setDataValue("cell_to_update","a new value");
}
}
which should update the cell with field "cell_to_update" but it doesnt.
I am wondering if that is because I am calling it from this specific callback?
One way is by forcing the refresh, like
onCellEditingStopped: {function(event) {
event.node.setDataValue("cell_to_update","a new value");
event.api.refreshCells({force:true});
}
}
I want to control row focus process. I need to show confirm dialog on row focus change in my table.
I tried to do this with rowClassRules property, but as I understood that functionality apply classes when table rendering, after that row classes stop changing
rowClassRules = {
'custom-row-focus': (params) => {
return params.data.id === this.currentSelectedItem.id
}
}
currentSelectedItem set's when I click on the row
Found an answer in docs
https://www.ag-grid.com/javascript-grid-row-styles/#refresh-of-styles
If you refresh a row, or a cell is updated due to editing, the rowStyle, rowClass and rowClassRules are all applied again.
So, when I'm clicking to the row I should make something like that:
onClicked($event: RowClickedEvent) {
$event.node.setData({...$event.data});
}
As an example, I have a Master\Detail grid.
Master\Detail defined as key-relation model and on getDetailRowData method parent node data exists in params
but how to get parent node data from child view?
Tried via context-menu:
On right click - getContextMenuItems got executed which has an input params
On this sample, child-grid doesn't have any row and node in context-params is null, it's ok,
but anyway it should be possible to retrieve the parent details at least via grid API, isn't it ?
Then I've tried to get parent via node:
but instead of detail_173 as you can see its ROOT_NODE_ID, and here is a confusion for me.
So question is that how to get parent node data (RecordID 173 just in case) through child-view context menu or any other possible way (without storing temp value, cuz multiple children's could be opened at the same time)
Yes, I've read this part Accessing Detail Grid API, and still unclear how to get parent-node via child-grid.
For React Hook users without access to lifecycle methods, use Ag-Grid Context to pass the parent node (or parent data) to the detail grid via detailGridOptions. No need to traverse the DOM or use a detailCellRenderer unless you want to :)
https://www.ag-grid.com/javascript-grid-context/
detailCellRendererParams: (masterGridParams) => ({
detailGridOptions: {
...
context: {
masterGrid: {
node: masterGridParams.node.parent,
data: masterGridParams.data
}
},
onCellClicked: detailGridParams => {
console.log(detailGridParams.context.masterGrid.node);
console.log(detailGridParams.context.masterGrid.data);
}
}
})
Able to achieve it. Have a look at the plunk I've created: Get master record from child record - Editing Cells with Master / Detail
Right click on any child grid's cell, and check the console log. You'll be able to see parent record in the log for the child record on which you've click.
The implementation is somewhat tricky. We need to traverse the DOM inside our component code. Luckily ag-grid has provided us the access of it.
Get the child grid's wrapper HTML node from the params - Here in the code, I get it as the 6th element of the gridOptionsWrapper.layoutElements array.
Get it's 3rd level parent element - which is the actual row of the parent. Get it's row-id.
Use it to get the row of the parent grid using parent grid's gridApi.
getContextMenuItems: (params): void => {
var masterId = params.node.gridOptionsWrapper.layoutElements[6]
.parentElement.parentElement.parentElement.getAttribute('row-id');
// get the parent's id
var id = masterId.replace( /^\D+/g, '');
console.log(id);
var masterRecord = this.gridApi.getRowNode(id).data;
console.log(masterRecord);
},
defaultColDef: { editable: true },
onFirstDataRendered(params) {
params.api.sizeColumnsToFit();
}
Note: Master grid's rowIds are defined with [getRowNodeId]="getRowNodeId" assuming that account is the primary key of the parent grid.
A very reliable solution is to create your own detailCellRenderer.
on the init method:
this.masterNode = params.node.parent;
when creating the detail grid:
detailGridOptions = {
...
onCellClicked: params => console.log(this.masterNode.data)
}
Here is a plunker demonstrating this:
https://next.plnkr.co/edit/8EIHpxQnlxsqe7EO
I struggled a lot in finding a solution to this problem without creating custom details renderer but I could not find any viable solution. So the real good solution is already answered. I am just trying to share another way to avoid creating custom renderer.
So What I did is that I changed the details data on the fly and added the field I required from the parent.
getDetailRowData: function (params: any) {
params?.data?.children?.forEach((child:any) => {
//You can assign any other parameter.
child.parentId= params?.data?.id;
});
params.successCallback(params?.data?.children);
}
When you expand the row to render details the method getDetailRowData gets called, so it takes in params as the current row for which we are expanding the details and the details table is set by invoking params.successCallback. So before setting the row data I am iterating and updating the parentId.
Using Angular 4 (typescript), I have some code like below using ag-grid 12.0.2. All I'm trying to do is load my grid and automatically (programmatically) select the first row.
:
this.gridOptions = ....
suppressCellSelection = true;
rowSelection = 'single'
:
loadRowData() {
this.rowData = [];
// build the row data array...
this.gridOptions.api.setRowData(this.rowData);
let node = this.gridOptions.api.getRowNode(...);
// console logging here shows node holds the intended row
node.setSelected(true);
// console logging here shows node.selected == true
// None of these succeeded in highlighting the first row
this.gridOptions.api.redrawRows({ rowNodes: [node] });
this.gridOptions.api.redrawRows();
this.gridOptions.api.refreshCells({ rowNodes: [node], force: true });
First node is selected but the row refuses to highlight in the grid. Otherwise, row selection by mouse works just fine. This code pattern is identical to the sample code here: https://www.ag-grid.com/javascript-grid-refresh/#gsc.tab=0 but it does not work.
Sorry I am not allowed to post the actual code.
The onGridReady means the grid is ready but the data is not.
Use the onFirstDataRendered method:
<ag-grid-angular (firstDataRendered)="onFirstDataRendered($event)">
</ag-grid-angular>
onFirstDataRendered(params) {
this.gridApi.getDisplayedRowAtIndex(0).setSelected(true);
}
This will automatically select the top row in the grid.
I had a similar issue, and came to the conclusion that onGridReady() was called before the rows were loaded. Just because the grid is ready doesn't mean your rows are ready.(I'm using ag-grid community version 19) The solution is to setup your api event handlers after your data has loaded. For demonstration purposes, I'll use a simple setTimeout(), to ensure some duration of time has passed before I interact with the grid. In real life you'll want to use some callback that gets fired when your data is loaded.
My requirement was that the handler resizes the grid on window resize (not relevant to you), and that clicking or navigating to a cell highlights the entire row (relevant to you), and I also noticed that the row associated with the selected cell was not being highlighted.
setUpGridHandlers({api}){
setTimeout(()=>{
api.sizeColumnsToFit();
window.addEventListener("resize", function() {
setTimeout(function() {
api.sizeColumnsToFit();
});
});
api.addEventListener('cellFocused',({rowIndex})=>api.getDisplayedRowAtIndex(rowIndex).setSelected(true));
},5000);
}
Since you want to select the first row on page load, you can do onething in constructor. But your gridApi, should be initialized in OnGridReady($event) method
this.gridApi.forEachNode((node) => {
if (node.rowIndex === 0) {
node.setSelected(true);
}
It's setSelected(true) that does this.
We were using MasterDetail feature, its a nested grid and on expanding a row we needed to change the selection to expanded one.
Expanding a row was handled in
detailCellRendererParams: {
getDetailRowData: loadNestedData,
detailGridOptions: #nestedDetailGridOptionsFor('child'),
}
and withing loadNesteddata, we get params using we can select expanded row as
params.node.parent.setSelected(true)
Hope this helps.
I'm currently using onAfterRendering() hook to auto adjust the layout of a table like this:
onAfterRendering: function() {
var table = this.getView().byId('table');
for (var i = 0; i < table.getColumns().length; i++) {
table.autoResizeColumn(i);
}
}
The result is not usable: all columns are sized 100% of the parent's width.
If I add a simple button to invoke the exact same logic the table gets drawn nicely. It looks like the complete table needs to be present in the DOM before autoResizeColumn() works properly.
My question: is there a suitable hook/event I can use to invoke the resizing once the table is in the document?
You can use the onAfterRendering of the table as suggested and add an if statement with bResized boolean or some kind of counter to prevent the endless loop.
As others have answered you can put add a function to oTable.onAfterRendering but the trick is if you do any rendering in that function it will trigger another rendering event that will again trigger onAfterRendering.
The problem here is where to hang the boolean switch that determine you have done the thing you have done.
One way to get around that is to add some customer data to the table with oTable.addCustomData.
The pattern becomes :
```
oTable.onAfterRendering = function () {
// check the prototype
// read the custom data
var customData = this.getCustomData();
// confirm *your* custom data is in the array (and not some other custom data)
// if not do your rendering operation and then
// set a switch to custom data
this.addCustomData(new sap.ui.core.CustomData({
key: "myRenderingCheck",
value: "true",
"writeToDom": true
}));
