Best Options for Data Binding

[Jean-Paul Malherbe]

Hi,

Is it possible to make use of the .Net2 BindingSource as the DataSource for the GridDataBoundGrid?

My Current Situation
We are making use of a List collection as the DataSource for a BindingSource, which in turn is being consumed by a DataGridView.

However, we find this to be extremely slow. Not only does the binding to the BindingSource take long, the DataGridView is increditly slow at refreshing. Put plainly, the performance is unacceptable.

What would be my best option for binding your grid to a collection of my custom objects? Please bear in mind that I need to be able to add/modify/delete rows before the records get persisted back to the database.

I tested your grid by implementing BindingList as the DataSource for the Grid. Do you have any other recommendations?

We are currently evaluating the grid and your assistance will be greatly appreciated.

Hi Jean,

Try setting the DataSource call with grid.BeginUpdate() and grid.EndUpdate() to see if that improves the performance.

grid.BeginUpdate();
grid.Binder.SuspendBinding();
grid.DataSource = Collections
grid.Binder.ResumeBinding();
grid.EndUpdate();

Please refer the browser sample that are shipped under Performance category.
\Essential Studio\3.3.0.1\Windows\Grid.Windows\Samples\DataBound\GridPerf example on GridDataBound Performance.

Let me know if you need any further assistance.
