jqxDataAdapter: what's the field 'record' for?

[pit007Member]

Hi,

in jqxDataAdapter, what’s the field ‘record’ for?

In the Grid’s example with nesting it’s set to ‘Employee’ in one case and ‘Order’ in the other.
However neither ‘Employee’ nor ‘Order’ seem to be used somewhere else.

In trying to clone the nesting example I set ‘record’ to another value only to find after hours of trial and error
that this was the reason no records are displayed in the grid.

Cheers
Peter

Hi Peter,

initrowdetails is called when you expand a row/record in jqxGrid. The “record” parameter is the expanded record in jqxGrid.

Thanks for the quick reply, Peter.

Unfortunately I don’t get it.
Where is the reference to ‘record’ or its contents ‘Employee’ or ‘Order’ in initrowdetails?

Which brings me to two other questions: what is ‘uid’ referring to in the line

var id = record.uid.toString();

Also, what’s purpose of

var filter_or_operator = 1;

the variable ‘filter_or_operator’ is never used. What’s it for? What is the meaning of ‘1’?

Many Regards
Peter

Hi Peter,

The “initrowdetails” is a function called by jqxGrid. It is not related to jqxDataAdapter. The “record” parameter is the expanded record in jqxGrid and contains the record’s data. For example, if you have a column with datafield=”firstName”, the record.firstName will give you the first name. uid is the record’s unique ID i.e the result of the Grid’s “getrowid” method call. To learn more about Data Binding with jqxGrid, read here: jquery-grid-datasources.htm and jquery-data-adapter.htm.
