You mean aggrid enterprise? Yes, thatās ok.
I tried the āinfiniteā mode, it works! Awesome.
How can I add other parameters into āgetRowsRequestā callback to make āserverSideā to work as well?

Correct.
What other parameters are you wanting? filterModel
and sortModel
are both available.
Check out here with how to use them:
For example, rowGroupCols and groupKeys to make this: React Data Grid: SSRM Row Grouping
And also similar things for pivoting.
At this time, it will take some effort to get a āserverSideā working.
We will let you know when it is actually available. Plus, if you are trying to do things like connect to a SQL from the clientside directly, that would take some custom coding.
Looks like Itās time to kick out some datatables and replace them with some ag grids instead
(Feels like one of those programs: how to spend only a few 1000s to make your home look and feel like its worth 100K more)
Good job
There is not a lot new in alpha release #4 - just a few bug fixes and a big prop cleanup. This might be our last pre-release prior to the full 2.0.0 release
If you havenāt tried dash-ag-grid, nowās the time!
It will only take a sec.
Do it!
Do it!
Do it now!
I know you want to
pip install dash-ag-grid==2.0.0a4
Hereās a simple app to try out some basic AG Grid features:
from dash import Dash, html, Input, Output
import dash_ag_grid as dag
import pandas as pd
df = pd.read_csv("https://raw.githubusercontent.com/plotly/datasets/master/solar.csv")
app = Dash(__name__)
grid = dag.AgGrid(
id="quickstart-grid",
rowData=df.to_dict("records"),
columnDefs=[{"field": i, "id": i} for i in df.columns],
defaultColDef={"resizable": True, "sortable": True, "filter": True},
columnSize="sizeToFit",
getRowId="params.data.State"
)
app.layout = html.Div([grid, html.Div(id="quickstart-output")])
@app.callback(
Output("quickstart-output", "children"), Input("quickstart-grid", "cellClicked")
)
def display_cell_clicked_on(cell):
if cell is None:
return "Click on a cell"
return f"clicked on cell value: {cell['value']}, column: {cell['colId']}, row index: {cell['rowIndex']}"
if __name__ == "__main__":
app.run_server(debug=True)
Thanks to everyone who tried the alpha versions of dash-ag-grid, with your help we have found and fixed (or more accurately, @jinnyzor fixed) all the reported issues. Now is the time to really put dash-ag-grid through the wringer - we would like to shake out any bugs prior to the full release.
For those of you who are on a3, when you upgrade to a4, it will likely break your app. But no worries, itās easy to fix. We deleted a lot of props, but they are still available, they just need to be included in dashGridOptions
or in the case of cellStyle
moved to the column definitions.
For example, most errors can be fixed like this:
# old way
dag.AgGrid(
rowSelection="multiple",
# other props
)
# new way
dag.AgGrid(
dashGridOptions={"rowSelection": "multiple"},
# other props
)
Update for the cellStyle
prop only:
# old way
dag.AgGrid(
cellStyle=cellStyle,
# other props
)
# new way
dag.AgGrid(
defaultColDef={"cellStyle": cellStyle},
# other props
)
Hi, is a custom comparator supported for date sorting? I have checked the source code and there is such an option but mainly for filtering and formatting. The sorting seems not to work as expected for my DateColum. Was looking at a custom sorting operator as with the original ag agrid: JavaScript Data Grid: Row Sorting
Yes, this should be working.
You can create your own javascript sorting in the namespace dashGridFunctions
and then use it like this: "comparator": {"function": "myCustomComparator"}
.
I havent tested it yet.
Ok iāll give it a try tomorrow and let you know
Did you see the example of parsing the date in this example?
This valueGetter
parses the date string into a date object, making is so you wonāt need a custom date sorting function (in most cases)
columnDefs = [
{
"headerName": "Date",
"filter": "agDateColumnFilter",
"valueGetter": {"function": "d3.timeParse('%d/%m/%Y')(params.data.date)"},
"valueFormatter": {"function": "params.data.date"},
},
]
You can see all the specifiers you can use depending on the format of the datestring in the last example on this page:
You were right. Being so hyped up about all the built-in conversion/formatting directly into the grid, I forgot that I actually needed mimic the part from my code where I convert the dates. thanks
Hi @AnnMarieW and @jinnyzor. Thank for all of your work.
I have a question that is there any way to fit all row in Div like sizeToFit
of columns? As you see it has White Space under dash ag grid.
import dash_ag_grid as dag
from dash import Dash, html, dcc
import requests
import pandas as pd
import json
data = pd.DataFrame({'Category': ['A', 'B', 'C'], 'Value': [1, 2, 3], 'Type': ['Circle','Square','Triangle']})
columnDefs = [{"field": x} for x in data.columns]
app = Dash(__name__)
app.layout = html.Div(
[
dcc.Markdown("This grid has resizeable columns with sort and filter enabled"),
dag.AgGrid(
columnDefs=columnDefs,
rowData=data.to_dict('records'),
columnSize="sizeToFit",
defaultColDef={"resizable": True, "sortable": True, "filter": True},
),
],
style={"margin": 20},
)
if __name__ == "__main__":
app.run_server(debug=False, port=8052)
Sure thing.
A lot of things come native to Dash AG grid from AG grid itself. And all of the props from the grid are available, if not on the first level, then inside dashGridOptions.
Check out here:
They do have a warning that using this can affect the performance, so use it sparingly.
We are continuing to work on the dash-ag-grid component to add new features and improve performance. We donāt expect any more breaking changes, so please feel free to take 2.0.0a4 for a spin!
There are still lots of features that have not yet been documented. Helping translate examples from the official AG Grid docs is a great way to contribute to this project
Here are the latest updates to the docs:
Getting Started section
Rows section
Layout & Style section
Rendering section
Components section
Row Pinning Example
Here is a little more on the Row Pinning. One use case is for adding a total row (when you are using AG Grid community and donāt have the Enterprise aggregation feature) In this example, the average is calculated in a Dash callback and it updates the Averages in the pinned bottom row. Note that the number formatting works automatically, and the totals stay with the columns as you move or resize them:
I havenāt been able to figure out a way just yet for you to be able to do this, it very well could be some additional support that we need to add.
I have this working, their exact example. Problem is that it did take some additional support.
This is great, thank you! I have a quick question⦠What component should I use to output data to an AG-Grid? Iām currently using āchildrenā, but when using something similar to the code below the table does not render. Thanks in advance!
table = dag.AgGrid(id=ātest_tableā)
Output(ātest_tableā, āchildrenā),
[Input(āsubmit_buttonā, ān_clicksā)]
