About creating and using a data source

[Leochan]

I created a data source as follow and am trying to show the data in a window. However, this error pops up : "ISC_Core.js:2051 POST PathToFile/SmartClient/SmartClient_v121p_2020-11-10_Pro/smartclientSDK/isomorphic/IDACall?isc_rpc=1&isc_v=v12.1p_2020-11-10&isc_xhr=1 net::ERR_FILE_NOT_FOUND"


//To Creating data source
isc.DataSource.create({
id:"tagDataSource",
fields:[
{name:"A"},
{name:"B"},
{name:...},
...
],
data: cData
});



//To Showing data
isc.Window.create({
title: "View Tag",
items: [
{title: "Tag List",
items: [
isc.ListGrid.create({
ID: "TagList",
dataSource: tagDataSource,
fields:[
{name:"A"},
{name:"B"},
{name:"..."},
...
],
})
]
});


But when I replace the "dataSource: tagDataSource" by "data: cData" directly, it works.

so. any idea how I should use the created data source properly?

MANY THANKS !!

Please take a look at the QuickStart Guide, Data Binding and Data Integration chapters. It's not clear what you expected to happen, but those chapters will clarify how DataSources work.

Hi Leochan,

try dataSource: "tagDataSource" (with quotes).
