Custom Validator for textbox does not fire on lost focus but on Insert button click in Add New Record mode for a RadGrid

[Priya]

1. I am trying to add validate a textbox with Custom Validator in the Add New Record mode for a radgrid. The server validate method is called on Insert button click rather than lost focus for the textbox.

2. I want to keep the radgrid in insert mode if validation fails. e.Canceled = true keeps the grid in Insert mode but the user entered values are lost. How can I keep the user entered values in the insert mode if custom validation fails?

 

Thanks
