[Solved] Several issues with Ajax binding

[Alexandre]

Hi,

I have several issues on my Telerik grid:

1. In Edit mode (pop-up), the validation which checks the fields required well works contrary to the custom validation. Indeed, I want to check if a date is greater than an other. I do this by creating a class "ValidationDate" which herits from "ValidationAttribute". When I want to submit the form, the validation well works but the error message is not displayed anywhere.
2. An other issue is when I apply an initial filter or sort  to my grid. After inserting, deleting or updating a record, I lose the initial filter.
3. The last issue is about performance. In my grid, I deal with hundreds of lines and it takes around ten seconds to display them.

I attach my application hoping you will bring me answers.
Thank you.

Alexandre
