Hello bartstripes,

RowAdding server side event is going to be triggered either when Enter key is pressed or Tab key is pressed to the last cell in the row. This is the moment when after entering data to Add New Row it loses focus. Only then this row is inserted in WebHierarchicalDataGrid and its underlying data source.

Some further reference about Row Adding feature could be found at:

http://help.infragistics.com/doc/ASPNET/2014.1/CLR4.0/?page=WebHierarchicalDataGrid_Enabling_Row_Adding.html

I tested your sample and the RowAdding event is correctly triggered when the enter key is pressed or when the last cell from the row is tabbed.

I hope you find this information helpful.

Please let me know if you need any further assistance with this matter.

Hi Tsanna, I tried again and you are correct the RowUpdating event is being fired properly. However,  I'm not able to get RowAdding to fire.

For the child add my steps are:

1. Expand the first row (Employee 0)
2. Enter values into the new child row for EmployeeID, First Name, Last Name, and Address (do not press enter)
3. Click the button

For the parent add my steps are:

1. Enter values into the new parent row at the bottom of the grid for EmployeeID, Name, OnSite, Department, and Site (do not press enter)
2. Click the button
