Hi All,
I’m trying to differentiate my pinned bottom row.
I found that cellRendererSelector must be put to defaultColDef.
but frankly speaking no idea how to use it.
I just want pinned row to to surpass any styling of other rows with bigger font and blue color.
'cellRendererSelector': {"function": "rowPinningBottom(params)"}
I’d be gratefull to pointing me where to find, in docs, rules for using js in Dash…
and Marry Christmass to everyone
Hi @acidkans
You can find an example in the docs here:
I have questions regarding styling and valueGetter of pinned row.
- Styling
I have simple styling of columns, based on being empty or not.
how to set completely different styling for pinned row.
get_row_style = {
"styleConditions":[
{
"condition": "!(params.data.invoice_number == null) ",
"style": {"backgroundColor": "#2aa198"},
"condition": "(params.node.rowPinned == 'bottom') ",
"style": {"backgroundColor": "#cb4b16", 'color': 'blue', 'fontWeight': 'bold','font-size':'24px'},
}],
}
- excluding ValueGetter for pinned row
I have my valueGetter (simple text concatanation) for one of the column but I’d like to exclude this value getter from pinned row…how can I add condition to value getter not to concatanate the text if row pinned ?
{'headerName': 'INVOICE DESCRIPTION',"wraptext":True,"filterParams":{"excelMode": "windows"},"autoHeight":True,
'valueGetter':{"function": "'Prace instalacyjne w tygodniu '+params.data.week +' na stacji '+ params.data.site +"
"', zgodnie z zamówieniem '+params.data.po_number + ' / Installation Arbeiten am '"
" + params.data.site + ', gemacht in KW '+ params.data.week + '; gemaß der Bestellung '"
"+params.data.po_number + '; akzeptiert am ' + params.data.acceptance_date +"
"' von ' + params.data.bauleiter;"}},
You need to test for the node to be pinned to the bottom.
Here, take this example:
import dash_ag_grid as dag
from dash import Dash, html, Input, Output, Patch, callback
import plotly.express as px
app = Dash(__name__)
df = px.data.gapminder()
columnDefs = [
{"field": "country", "checkboxSelection": True},
{
"field": "lifeExp",
"type": "rightAligned",
# "valueFormatter": {"function": "d3.format('.1f')(params.value)"},
"valueGetter": {"function": "params.node.rowPinned == 'bottom' ? 'bottom' : null"}
},
{
"field": "pop",
"type": "rightAligned",
# "valueFormatter": {"function": "d3.format(',.0f')(params.value)"},
},
{
"field": "gdpPercap",
"type": "rightAligned",
# "valueFormatter": {"function": "d3.format('$,.2f')(params.value)"},
},
]
app.layout = html.Div(
[
dag.AgGrid(
id="row-pinning-top",
rowData=df.to_dict("records"),
columnDefs=columnDefs,
defaultColDef={"editable": True, "sortable": True, "filter": True, "resizable": True},
columnSize="sizeToFit",
dashGridOptions={"rowSelection": "multiple"},
),
],
)
@callback(
Output("row-pinning-top", "dashGridOptions"),
Input("row-pinning-top", "selectedRows"),
)
def row_pinning_top(selected_rows):
grid_option_patch = Patch()
grid_option_patch["pinnedBottomRowData"] = selected_rows
return grid_option_patch
if __name__ == "__main__":
app.run(debug=True, port=8000)

sorry for kindergarten question regarding js syntax
'valueGetter':{"function": "params.node.rowPinned == 'bottom' ? *(value if condition False)* : *(value if condition TRUE)*"}}
below aplication just cut off value getter for whole column
'valueGetter':{"function": "params.node.rowPinned == 'bottom' ?
('Prace instalacyjne w tygodniu '+params.data.week +' na stacji '+ params.data.site +"
"', zgodnie z zamówieniem '+params.data.po_number + ' / Installation Arbeiten am '"
" + params.data.site + ', gemacht in KW '+ params.data.week + '; gemaß der Bestellung '"
"+params.data.po_number + '; akzeptiert am ' + params.data.acceptance_date +"
"' von ' + params.data.bauleiter;) : null"}},
You need to do the inverse:
'valueGetter':{"function": "params.node.rowPinned != 'bottom' ?
('Prace instalacyjne w tygodniu '+params.data.week +' na stacji '+ params.data.site +"
"', zgodnie z zamówieniem '+params.data.po_number + ' / Installation Arbeiten am '"
" + params.data.site + ', gemacht in KW '+ params.data.week + '; gemaß der Bestellung '"
"+params.data.po_number + '; akzeptiert am ' + params.data.acceptance_date +"
"' von ' + params.data.bauleiter;) : null"}},
And the syntax of the above is:
evaluates if statement ? return if true : return if false
Hi jinnyzor,
how would I check for pinning row in case of row styling.
I use row styling and cell styling.
and these styling overlap on pinned row, it looks awfull, how could I add same function
“function”: "params.node.rowPinned == ‘bottom’ to use different styling for pinned row.
for rows I use:
get_row_style = {
"styleConditions":[
{
"condition": "!(params.data.invoice_number == null) ",
"style": {"backgroundColor": "#2aa198"},
"condition": "(params.node.rowPinned == 'bottom') ",
"style": {"backgroundColor": "#cb4b16", 'color': 'blue', 'fontWeight': 'bold','font-size':'24px'},
}],
}
for columns I use cellStyle:
'cellStyle': {'styleConditions':
[{
'condition': '(params.value == null)',
'style': {"backgroundColor": "#fd7e14"},
I know"I am overstepping your kindness
Instead of cellStyle, you should use cellClassRules
, as these will refresh when a row is updated.
Then just add an additional css sheet with your styles.
If you want to go this route, then you should add an event listener to the pinnedRowDataChanged
, like this:
app.clientside_callback(
"""function (id) {dash_ag_grid.getApiAsync(id).then((grid) => {grid.addEventListener('pinnedRowDataChanged', () => grid.refreshCells())})
return dash_clientside.no_update
}""",
Output('row-pinning-top', 'id'), Input('row-pinning-top','id')
)
