I am trying to use grouped rows in ag grid. I would like there to be only one group allowed to be opened at once as there are a large mount of children rows and it is becoming laggy. I also have two columns that only apply to child rows and would like these to expand when a group is open and to be hidden when no group is expanded. This is what I have so far.
const rowGroupExpand = (params: RowGroupOpenedEvent) => {
if (params.node.expanded) {
gridApi?.forEachNode(function (node) {
if (node.expanded && node.group && node.id !== params.node.id && node.uiLevel === params.node.uiLevel) {
console.log(node);
node.expanded = false;
}
});
columnApi?.setColumnsVisible(['theatre session performance', 'theatre utilisation graph'], true);
} else {
columnApi?.setColumnsVisible(['theatre session performance', 'theatre utilisation graph'], false);
}
gridApi?.redrawRows();
};
<Grid
rowData={theatreData}
columns={theatreSessionsColDef()}
setGridApi={setGridApi}
setColumnApi={setColumnApi}
onRowGroupOpened={rowGroupExpand}
/>
however when a group is open and another is opened everything collapses, and I can't figure out why.

How can i stop this onClick event from rerendering the entire treemap echart i have?
I have basically a echarts treemap https://echarts.apache.org/examples/en/editor.html?c=treemap-disk as a functional component in react. I need to be able to apply filters and "grey out" certain tree nodes that dont fit the criteria. This functionality works currently but it rerenders the echart so that the user must restart from the top level and clicktheir way through all the way to the bottom level. How can i avoid the rerendering? This is a similar example i have where clicking the node displays data but also rerenders the chart losing where the node was in the map.
const onChartClick = params => {
if (params.treePathInfo.length === 9) {
setDrawerData(params);
}
};
useEffect(() => {
props.setDrawerData(drawerData);
}, [drawerData]);
const onEvents = {
click: onChartClick,
}; ```
you can try to put your chart on useMemo it works for me :
const [dataLoaded, setdataLoaded] = useState(true);
const onChartClick = params => {
if (params.treePathInfo.length === 9) {
setDrawerData(params);
}
};
useEffect(() => {
props.setDrawerData(drawerData);
setdataLoaded(false)
}, [drawerData]);
const onEvents = {
click: onChartClick,
};
const MemoChart = useMemo(() => <Charts
option={option}
onEvents={onEvents}
/>, [dataLoaded]);
I am trying to render a set of footnotes at the end of my data set. Each footnote should be a full-width row. On the docs page for row height, it says that you can set an autoHeight property for the column you want to use to set the height. Full-width rows, however, aren't tied to any column, so I don't think there's a place to set that autoHeight property.
For reference, here is my cell renderer, which gets invoked if a flag in the data object is true.
import { Component } from '#angular/core';
import { ICellRendererComp, ICellRendererParams } from '#ag-grid-community/core';
#Component({
template: '',
})
export class FootnoteRendererComponent implements ICellRendererComp {
cellContent: HTMLElement;
init?(params: ICellRendererParams): void {
this.cellContent = document.createElement('div');
this.cellContent.innerHTML = params.data.title;
this.cellContent.setAttribute('class', 'footnote');
}
getGui(): HTMLElement {
return this.cellContent;
}
refresh(): boolean {
return false;
}
}
The footnote (the "title" property above) could be one line or several depending on its length and the browser's window size. There may also be several footnotes. Is there a way to set autoHeight for each footnote row? Thanks for any help!
Not sure of CSS autoHeight can be use, but here is some example for calculating height dynamically. Take a look to getRowHeight function, it's works for any rows (full-width too):
public getRowHeight: (
params: RowHeightParams
) => number | undefined | null = function (params) {
if (params.node && params.node.detail) {
var offset = 80;
var allDetailRowHeight =
params.data.callRecords.length *
params.api.getSizesForCurrentTheme().rowHeight;
var gridSizes = params.api.getSizesForCurrentTheme();
return (
allDetailRowHeight +
((gridSizes && gridSizes.headerHeight) || 0) +
offset
);
}
};
Here is the solution I ended up with, though I like #LennyLip's answer as well. It uses some ideas from Text Wrapping in ag-Grid Column Headers & Cells.
There were two parts to the problem - 1) calculating the height, and 2) knowing when to calculate the height.
1) Calculating the Height
I updated the footnote's Cell Renderer to add an ID to each footnote text node, and used it in the function below.
const footnoteRowHeightSetter = function(params): void {
const footnoteCells = document.querySelectorAll('.footnote .footnote-text');
const footnoteRowNodes = [];
params.api.forEachNode(row => {
if (row.data.dataType === 'footnote') { // Test to see if it's a footnote
footnoteRowNodes.push(row);
}
});
if (footnoteCells.length > 0 && footnoteRowNodes.length > 0) {
footnoteRowNodes.forEach(rowNode => {
const cellId = 'footnote_' + rowNode.data.id;
const cell = _.find(footnoteCells, node => node.id === cellId);
const height = cell.clientHeight;
rowNode.setRowHeight(height);
});
params.api.onRowHeightChanged();
}
};
To summarize, the function gets all HTML nodes in the DOM that are footnote text nodes. It then gets all of the table's row nodes that are footnotes. It goes through those row nodes, matching each up with its DOM text. It uses the clientHeight property of the text node and sets the row node height to that value. Finally, it calls the api.onRowHeightChanged() function to let the table know it should reposition and draw the rows.
Knowing when to calculate the height
When I set the gridOptions.getRowHeight property to the function above, it didn't work. When the function fires, the footnote rows hadn't yet been rendered, so it was unable to get the clientHeight for the text nodes since they didn't exist.
Instead, I triggered the function using these event handlers in gridOptions.
onFirstDataRendered: footnoteRowHeightSetter,
onBodyScrollEnd: footnoteRowHeightSetter,
onGridSizeChanged: footnoteRowHeightSetter,
onFirstDataRendered covers the case where footnotes are on screen when the grid first renders (short table).
onBodyScrollEnd covers the case where footnotes aren't on screen at first but the user scrolls to see them.
onGridSizeChanged covers the case of grid resizing that alters the wrapping and height of the footnote text.
This is what worked for me. I like #LennyLip's answer and looking more into it before I select an answer.
I am unable to find any way to disable checkbox node using angular tree component.
There is no option to mark the tree disabled so that the checkboxes that appear alongwith th etree data should be disabled. Please suggest
Disabling the node can be done by actionMapping inside options attribute https://angular2-tree.readme.io/v1.2.0/docs/options. Here click event of mouse can be overwritten.
<Tree [nodes]="nodes" [options]="treeOptions"></Tree>
In my tree data I kept an attribute isSelectable on each node, which is true|false. In case of true i proceed selecting the node otherwise it does not do anything. Here are full options that I am passing to the tree component.
public options: ITreeOptions = {
isExpandedField: 'expanded',
idField: 'uuid',
getChildren: this.getChildren.bind(this),
actionMapping: {
mouse: {
click: (tree, node, $event) => {
if ( node.data.isSelectable ) {
this.isNodeSelected.emit(node.data);
this.alreadySelected = true;
this.preSelected.tree = tree;
this.preSelected.node = node;
this.preSelected.event = $event;
TREE_ACTIONS.ACTIVATE(this.preSelected.tree, this.preSelected.node, this.preSelected.event);
}
}
}
},
nodeHeight: 23,
allowDrag: (node) => {
return false;
},
allowDrop: (node) => {
return false;
}
};
When using the row grouping feature provided by the ag-Grid, there is inserted a new 'row' as the header of the group, the click expand / collapse area which identifies that group.
Is there any way to access this row?
It is not present in row data which populates the grid.
this.autoGroupColumnDef = {
field: "column",
headerName: " Column containing the expand / collapse rows ",
valueGetter: function nameGetter(params) {
console.log("All rows: ", params.data); // group rows not present here
return params.data.nameToDisplay;
}
}
Since there is no clarity with the above code, I can just suggest you to identify which row is a group and which is not.
You can call the onModelUpdated which gets called on page load and on any update to the ag-grid.
*Example:*
onModelUpdated = (params) => {
params.api.forEachNode((node) => {
if (node.group) {
console.log('Row data', node);
} else {
//do nothing
}
});
}
node.group returns either true or false
I need to provide a background color for an entire row in ag grid based on a condition in a column. I found no such examples where entire row is colored based on a certain value in a column..
The previous answer is somewhat outdated (although still correct and working) and now we have some more control over the styling of the grid. You could use getRowStyle(params) for this job, just like this:
gridOptions.getRowStyle(params) {
if (params.data.myColumnToCheck === myValueToCheck) {
return {'background-color': 'yellow'}
}
return null;
}
Obviously, myColumnToCheck would be the column you're checking your value against (the same name you input in the id/field property of the colDef object), and myValueToCheck would be the value you want said column to have to make the row all yellow.
I hope this helps others. A very common use case in any table or grid including AG Grid is going to be to set the even/odd background color of the whole row of the entire table in a performant way. ALSO, this needs to still work when SORTING.
ALL OF THESE WAYS OF DOING THIS IN AG-GRID ARE WRONG. Even though they WILL work without sort, they will not update properly when you go to use sorting. This is due to something the ag-grid team refers to in this issue https://github.com/ag-grid/ag-grid-react/issues/77 as initialization time properties.
// Initialization problem
getRowClass = (params) => {
if (params.node.rowIndex % 2 === 0) {
return this.props.classes.rowEven;
}
};
<AgGridReact
getRowClass={this.getRowClass}
>
// Initialization problem
getRowStyle = (params) => {
if (params.node.rowIndex % 2 === 0) {
return this.props.classes.rowEven;
}
};
<AgGridReact
getRowStyle={this.getRowStyle}
>
// Initialization problem
rowClassRules = {
rowEven: 'node.rowIndex % 2 === 0',
}
rowClassRules = {
rowEven: (params) => params.node.rowIndex % 2 === 0,
}
<AgGridReact
rowClassRules={this.rowClassRules}
>
// Trying to change the key so a rerender happens
// Grid also listens to this so an infinite loop is likely
sortChanged = (data) => {
this.setState({ sort: Math.random()})
}
<AgGridReact
key={this.state.sort}
onSortChanged={this.sortChanged}
>
Basically, most stuff in grid is just read once and not again, probably for performance reasons to save rerenders.
You end up with this problem when sorting when doing any of the above:
THE FOLLOWIUNG IS THE RIGHT WAY TO ACHIEVE EVEN ODD COLORING:
The correct way to add even/odd functionality in ag-grid is to apply custom css styles as follows:
You will need to overwrite/use ag variables as mentioned in the docs here:https://www.ag-grid.com/javascript-grid-styling/#customizing-sass-variables
The names of the variables in our case are
.ag-grid-even class name, or the .ag-grid-odd class name. You of course only need one if you just want an alternating color to help with visibility. For our purposes we only needed one.
Here is how this process looked in our repo:
1. Make a custom css file that overwrites/uses some of these ag- class variable names. We call it ag-theme-custom.css (I believe it needs to be a css file).
Note: We also have sass variables so this file just has a comment that this color I am adding in css is the value for our variable $GREY_100 so you don't need that part
You now will get the same result but it will still work when sorting.
Answer 2 is correct, but the syntax used is wrong, and caused me several problems trying to sort it out. Trying to minify the answer 2 code barfed, for example. It did work, but it's not proper syntax as far as I can see.
Note, this can be done inline, or with an external
function. For example an external function.
vm.gridOptions = {
columnDefs: columnDefs,
getRowStyle: getRowStyleScheduled
}
function getRowStyleScheduled(params) {
if (params.selected && params.data.status === 'SCHEDULED') {
return {
'background-color': '#455A64',
'color': '#9AA3A8'
}
} else if (params.data.status === 'SCHEDULED') {
return {
'background-color': '#4CAF50',
'color': '#F4F8F5'
};
}
return null;
};
You can add CSS classes to each row in the following ways:
rowClass: Property to set CSS class for all rows. Provide either a string (class name) or array of strings (array of class names).
getRowClass: Callback to set class for each row individually.
<ag-grid-angular
[rowClass]="rowClass"
[getRowClass]="getRowClass"
/* other grid options ... */>
</ag-grid-angular>
// all rows assigned CSS class 'my-green-class'
this.rowClass = 'my-green-class';
// all even rows assigned 'my-shaded-effect'
this.getRowClass = params => {
if (params.node.rowIndex % 2 === 0) {
return 'my-shaded-effect';
}
};
You can define rules which can be applied to include certain CSS classes via the grid option rowClassRules.
The following snippet shows rowClassRules that use functions and the value from the year column:
<ag-grid-angular
[rowClassRules]="rowClassRules"
/* other grid options ... */>
</ag-grid-angular>
this.rowClassRules = {
// apply green to 2008
'rag-green-outer': function(params) { return params.data.year === 2008; },
// apply amber 2004
'rag-amber-outer': function(params) { return params.data.year === 2004; },
// apply red to 2000
'rag-red-outer': function(params) { return params.data.year === 2000; }
};
You can't change the background color of an entire row in one command. You need to do it through the cellStyle callback setup in the columnDefs. This callback will be called per each cell in the row. You need to change the color of the row by changing the color of all the cells.
See the following column definition
{
headerName: "Street Address", field: "StreetAddress", cellStyle: changeRowColor
}
You need to do this for all your columns.
Here is your changeRowColor function.
function changeRowColor(params) {
if(params.node.data[4] === 100){
return {'background-color': 'yellow'};
}
}
It changes the color of a row if the value of the third cell is 100.
I set different color for even and odd rows you can do it in any way..
$scope.gridOptions.getRowStyle = function getRowStyleScheduled(params){
if(parseInt(params.node.id)%2==0) {
return {'background-color': 'rgb(87, 90, 90)'}
}else {
return {'background-color': 'rgb(74, 72, 72)'}
}
};
If you don't need to set the background color conditionally(based on the row data), it is not recommended to use rowStyle, as written on the row style documentation page:
// set background color on even rows
// again, this looks bad, should be using CSS classes
gridOptions.getRowStyle = function(params) {
if (params.node.rowIndex % 2 === 0) {
return { background: 'red' };
}
}
Instead, you can change the row colors using css:
#import "~ag-grid-community/dist/styles/ag-grid.css";
#import "~ag-grid-community/dist/styles/ag-theme-alpine.css";
#import "~ag-grid-community/dist/styles/ag-theme-balham.css";
#import "~ag-grid-community/src/styles/ag-theme-balham/sass/ag-theme-balham-mixin";
.ag-theme-balham {
#include ag-theme-balham((
// use theme parameters where possible
odd-row-background-color: red
));
}
If you are using AdapTable then the simplest way is to use a Conditional Style and apply it to a whole row.
The advantage of this is that it can be at run-time easily by users also.
