When using Ag-Grid's server side row model, I am unable to send a custom group key to the server in order to do proper group by queries.
My row data is a simple JSON structure but with one composite object.
row = {
athlete: '',
age: '',
country: {
name: 'Ireland',
code: 'IRE'
},
...
}
I am using the server side row model. To get the grid to display the country name is simple enough as I use the following column definition.
{
headerName: "Country",
colId: "country",
valueGetter: "data.country.name",
enableRowGroup: true
}
However, when I group by the Country column ag-grid sends the groupKey as 'Ireland' from my example above. But I need the group key to be the country code, 'IRE'. I cannot figure out how to generate a groupKey when using the server-side row model.
I have seen the keyCreator method, but this only works for client-side row model. In addition, I have seen the Tree Data Mode which has a callback for getServerSideGroupKey(dataItem) but then callback only gets used when gridOptions.treeData = true and when the treeData option is set to true, a "Group" column is always displayed regardless if a grouping is happening or not. I tested this out by setting isServerSideGroup: function(dataItem) {return false;}
Any help would be appreciated.
I was able to solve this issue by using the dot notation for the column definition's field attribute and a custom cellRenderer.
{
headerName: "Country",
colId: "country",
field: "country.code",
enableRowGroup: true,
cellRenderer: function (params) {
return params.data.country.name;
}
}
This allowed me to display the correct data point from the custom object and when doing server side actions, ag-grid will send the datapoint contained within the field attribute.

I recently changed my tables to Mui-datagrid on Material UI 5, and I have a special use case with an array of objects. I want to enable the phone number filter in this column, but the number is provided as an object list.
phone: [
{ type: "home", number: "795-946-1806" },
{ type: "mobile", number: "850-781-8104" }
]
I was expecting a 'customFilterAndSearch' or an option to customise how to search in this specific field.
customFilterAndSearch: (term, rowData) =>
!!rowData?.suppressedOptions.find(({ description }) =>
description?.toLowerCase().includes(term.toLowerCase())
),
I have made some tries with the filterOperators, but no success yet. I have made a full example here https://codesandbox.io/s/mui-data-grid-vs05fr?file=/demo.js
As far as I can see from the DataGrid documentation I don't see any way to change the filter function for a specific function.
Likely the best workaround for your use case will be converting this to a string be converting the data to a string before you pass it to the datagrid. Though you will lose the styling that you currently do by making the phone type bold.
On second though your best best would probably be to split the phone column into two columns which would probably be the cleanest way of solving your problem
Add helper function.
You could potentially add a helper function to just map all the phone lists to something like mobilePhone or homePhone
const mapPhoneObject = (rows) => {
rows.forEach((row) => {
row.phone.forEach((phone) => {
row[`${phone.type}Phone`] = phone.number;
});
});
return rows
};
I've added a fork of your snippet with my function, it is I think the most viable solution for your problem: https://codesandbox.io/s/mui-data-grid-forked-ppii8y
In documentation, sorting api i.e columns API method "applyColumnState" used for sorting multiple columns on external button click
But Can we sort multiple columns on a Column header click?
For eg, On Column A header cell click I want Column A to be sorted desencding and Column B to be sort ascending. Is this possible?
from the docs : https://www.ag-grid.com/documentation/javascript/row-sorting/#sorting-api
you can manually sort through multiple columns, one after one using the ColumnState API:
gridOptions.columnApi.applyColumnState({
state: [
{ colId: 'country', sort: 'asc', sortIndex: 0 },
{ colId: 'sport', sort: 'asc', sortIndex: 1 },
],
defaultState: { sort: null },
});
if you want to click on a header and sort an other one, you can disable sorting on the header in question, listen for the click on it an execute the above applyColumnState to manually sort.
you can listen to the click on the header by adding a listener on the .ag-header-cell class (https://stackoverflow.com/a/57812319/6641693) or simply by creating your own header component that would trigger any function you want using headerComponentFramework on the column Definition :
headerComponentFramework: (params) =>{
return (
<div>
.....
</div>
)
}
I am using ag-grid enterprise 20.2 using server side and have a column where I would like to use the agSetColumnFilter filter type. The column and filter display fine, but when I go to check a filter checkbox it returns from filterModel empty and no checkboxes are changed.
{
headerName: 'header,
field: 'field',
width: 150,
filter: 'agSetColumnFilter',
filterParams: {
values: (valuesParams) => {
const values = Object.entries(field_values).map(e => e[1].id);
valuesParams.success(values);
},
},
},
I am guessing that there is a callback or something to update the filter (setModel?), but I have not been able to sort out what the API is. Could someone let me know how to do this?
This looks to be a bug in the software. I changed to rowModelType="infinite" leaving almost everything else the same and it now works.
I've created the following Input field.
var oCityInput = new Input({ // sap/m/Input
showSuggestion: true,
showTableSuggestionValueHelp: true,
suggestionItems:{
path: "/cities",
template: new ListItem({ // sap/ui/core/ListItem
text: "{cname}",
additionalText: "{provi}"
}),
},
});
The "cities" array contains around 8400 record, but when I type some character the suggestion function it seems that is looking for only in the first 100 items of the array.
I've created an example in jsbin. If you try to looking for the first elements it works... but if you try to type the last city the suggestion will not come out.
In newer versions of SAP UI5 the JSONModel also supports the setSizeLimit() method:
model.setSizeLimit(iNumOfYourJsonEntries);
API description: "Set the maximum number of entries which are used for list bindings."
Be careful because it can lead to performance issues.
I have utilised the example code at Example Code at this link
and I have got my grid to show a dynamically constructed select dropdown on add and edit. However when it is just showing the data in the grid it shows the dropdown index instead of its associated data. Is there a way to get the grid to show the data associated with the index instead of the index itself.
e.g. the data on my select could be "0:Hello;1:World"; The drop down on the edit/add window is showing Hello and World and has the correct indexes for them. If the cell has a value of 1 I would expect it to show World in the grid itself but it is showing 1 instead.
Here is the row itself from my grid:
{ name: 'picklist', index: 'picklist', width: 80, sortable: true, editable: true,
edittype: "select", formatter: "select", editrules: { required: true} },
I am filling the dynamic data content in the loadComplete event as follows:
$('#mygrid').setColProp('picklist', { editoptions: { value: picklistdata} });
picklist data is a string of "0:Hello;1:World" type value pairs.
Please can anyone offer any help. I am fairly new to JQGrids so please could you also include examples.
I know you have already solved the problem but I faced the same problem in my project and would like to offer my solution.
First, I declare a custom formatter for my select column (in this case, the 'username' column).
$.extend($.fn.fmatter, {
selectuser: function(cellvalue, options, rowdata) {
var userdata;
$.ajax({
url:'dropdowns/json/user',
async:false,
dataType:'json',
cache:true,
success: function(data) {
userdata = data;
}
});
return typeof cellvalue != 'undefined' ? userdata[cellvalue] : cellvalue ;
}
});
This formatter loads up the mapping of id and user in this case, and returns the username for the particular cellvalue. Then, I set the formatter:'selectuser' option to the column's colModel, and it works.
Of course, this does one json request per row displayed in the grid. I solved this problem by setting 10 seconds of caching to the headers of my json responses, like so:
private function set_caching($seconds_to_cache = 10) {
$ts = gmdate("D, d M Y H:i:s", time() + $seconds_to_cache) . " GMT";
header("Expires: $ts");
header("Pragma: cache");
header("Cache-Control: max-age=$seconds_to_cache");
}
I know this solution is not perfect, but it was adequate for my application. Cache hits are served by the browser instantly and the grid flows smoothly. Ultimately, I hope the built-in select formatter will be fixed to work with json data.
If you save in jqGrid ids of the select elements and want to show the corresponding textes then you should use formatter:'select' in the colModel (see http://www.trirand.com/jqgridwiki/doku.php?id=wiki:predefined_formatter#formatter_type_select) together with the edittype: "select".
The Usage of stype: 'select' could be also interesting for you if you plan to support data searching.
