a!gridField sorting issue

Hi saurak,

You have to define field attribute in a!gridTextColumn() to make that field sort as shown bellow.

a!gridTextColumn(
label: "Text Column",
data: {},
field:"firstName"
) 

its declared already. I am able to click on column header but its not sorting.

What data your mapping that also causes error, because the data should be always primitive data type, so type cast that field value to primitive data type and try , it may works.

its text only.

Can you share your code and error that your getting, that might helps us to better understand .

a!gridTextColumn(
label: "Test By",
field: "createBy",
data: if(
rule!APN_isBlank(
ri!testSet.data
),
{},
a!forEach(
items: index(
ri!testSet.data,
"testBy",
null
),
expression: rule!HELLO_getUserName(
fv!item
)
)
)

),

Error is: Nothing is happening after clicking on column header.

I think data your mapping is "testBy" and doing sorting by "createBy" is both same data type ? and try to give index instead dot(.) in data.

yes both are same data type. Plz update where you are saying. Then will try again

Try This,

{
with(
local!gridValues: todatasubset(
index(
ri!testSet,
"data",
null
),
ri!paggingInfo
),
a!gridField(
label: "Paging Grid",
labelPosition: "ABOVE",
totalCount: 0,
columns: {
a!gridTextColumn(
label: "Test By",
field: "createBy",
data: if(
rule!APN_isBlank(
local!gridValues.data
),
{},
a!forEach(
items: index(
index(
local!gridValues,
"data",
{}
),
"createBy",
null
),
expression: rule!HELLO_getUserName(
fv!item
)
)
)
)
},
value: ri!paggingInfo,
saveInto: ri!paggingInfo,
validations: {},
shadeAlternateRows: true
)
)
}

getting below error.

Error Evaluating UI Expression
Expression evaluation error in rule 'grid rule' (called by rule 'interface name') at function a!gridField: A grid component [label=“Hello to all”] has an invalid value for “columns” and “value”. All “data” arrays must not contain more items than the specified “batchSize”, but “batchSize” was 10 and the largest column data array had 500 items

Make changes to total count :

totalCount: index(local!gridValues,"totalCount",null),

Hi ,

Above issue resolved but sorting is not working.

a!gridTextColumn(
label: "Lead By",
field: "leadBy",
data: if(
rule!APN_isBlank(
ri!dataset.data
),
{},
a!forEach(
items: index(
ri!dataset.data,
"leadBy",
null
),
expression: rule!TEST_getLeadershipDetails(
fv!item
)
)
)
),

I have tried with local!pagingInfo , tried direct saving paginginfo at field level.Nothing is getting impact.

PagingInfo is not able to recognized filed name . With our without same result is coming.

Hi Saurav,

As per my understanding, when you are trying to sort this column, it is getting sorted by createBy field (Usernames). And then you are applying foreach on usernames to get the formatted data and display in grid. (Please note that this function will be applied on datasubset which is already sorted based on the usernames. Means sorting is done first and then computation is happening later to display data). I would suggest build the datasubset first and just use that datasubset in grid. Something like below

 load(
local!datatoDisplay:a!forEach(ri!testSet.data,{createBy:tostring(fv!item.createBy),newColumn:tostring(user(fv!item.createBy,"firstName")&", "&user(fv!item.createBy,"lastName"))}),
with(
local!dataSet:todatasubset(local!datatoDisplay,ri!paggingInfo),

a!gridField(
label: "Paging Grid",
labelPosition: "ABOVE",
totalCount: local!dataSet.totalCount,
columns: {
a!gridTextColumn(
label: "username",
field: "createBy",
data: local!dataSet.data.createBy
),
a!gridTextColumn(
label: "Test By",
field: "newColumn",
data: local!dataSet.data.newColumn
)
},
value: ri!paggingInfo,
saveInto: ri!paggingInfo,
validations: {},
shadeAlternateRows: true
))
)

Alternatively, you can use plugin function like updatecdt() to update one field in CDT with required computation and use that CDT to build datasubset for grid.
