Using a data source diferent than a database


User (Legacy)

Recommended Posts

We are creating a DataTable on code not using a data source and the ChartFX

says there is no data on the set, but there is data alright. By some reason

it dosent get the data in it, if I connect it directly to the data source it

works. A ListProvider also works fine, but need to add servral series and a

ListProvider seems to accept only one. How can fill the Grid with data using

a DataSource on a on memory basis not from a database.

Hugo

We are creating the DataTable on line, not from the data base with somthing

like this, and it dosen't work if we use the database directly it works

fine.

We are using somthing like this to create the new table.

Dim dtResult As New DataTable("Heats")

For Each colName In aCols

dtResult.Columns.Add(New DataColumn(colName, dt.Columns(colName).GetType()))

Can you post a small sample code that contains the table creation and chart

customization ?

Thanks,

We found the trouble it was a mistake we made on a data type here:

dtResult.Columns.Add(New DataColumn(colName, dt.Columns(colName).GetType()))

In runtime nothing crashed sadly,
