Performance comparison for normal ListGrid & DataBound ListGrid

[mohit.singla]

I am using SmartGWT 3.1

DataBound ListGrid uses DataSource and all data addition, deletion, updation happens through DataSource. This method is really convenient but I have some doubts over the performance over normal Listgrid with ListGridRecords.

Observation: All the cells of all rows get updated even if you make changes in single row a single cell during UPDATE operation or updateCaches() method execution.

Also if we set Data with ListGridRecord in ListGrid without DataSource, I think the performance can be improved.

Please confirm this observation and suggest if any improvement can be made in DataSource Type approach.

No, your speculations as to performance are quite wrong. DataSources should always be used for a use case like you describe.

Please clarify about your response.
Do you mean that updation of value of all cells for all rows is expected in case of DataSource even if value in one particular cell of a row is updated.?

Or do you mean that my observation about DataSource is wrong?

I am looking for a method where only affected cell's value is changed/refreshed while the unchanged cells are not touched during updateValue operations.

Please give your opinion.
