Hi,

There must be single SelectionModel, it doesn't support multiple selection models.

[RonaldR]

Does the v1.0 Supports this?

[Daniil]

No, it's also not supported in Ext.Net 1.0.

Please describe your requirement.

[RonaldR]

I wanted to give the Users two features:

1. check-boxes to select rows to add a Business Logic's too

1. clicking on a Row to Edit that row, which shows a Pop-up window... (I currently have an Edit Button at the end of each Row)

[Daniil]

You could use CheckboxSelectionModel only. This class is inherits from RowSelectionModel one. So, this has all its functionality with additional 'checkbox' feature.

I see, thank you very much for your explanation...
