Hello,

I am just checking the progress of this issue and was wondering if you managed to achieve your goal or if you need any further assistance on the matter.      

Hello,

I have modified the sample Krasimir has sent you, so now it works as you want. Basically I handled the XamGrid’s RowAdding event and check if the canAdd is true or false and cancel or not the event. Also I removed the handler for the KeyDown event, so now the null reference exception is no longer thrown when you press escape. Please let me know if this helps you or you need further assistance on this matter.

Looking forward for your reply.

Thank you for the reply.

But your solution is not totally correct.Its crashing in several scenarios.Below are the steps to replicate:-

1.) Select a date in datepicker in the grid and hit enter. It will add the row in the grid , i.e fine.

2.) then again select a date and hit escape key. The solution will crash with null exception.

Second issue is :- its still adding the row in lost focus.

Steps to replicate:-

1.)  select a date from date picker and hit enter. It will add the row.

2.) again select an item and click anywhere in the grid. It will again add the new row. It should not add. It should add only on enter key.

But if you again select any date (i.e. third time) , then it will work fine , only on enter clcik it will add new row.

Again on 4th time , it will add on lost focus.

It behaves wrongly only on even times. or after every enter clcik when you select something then on lost focus it will add new row.
