Dear all,
a quick question: I am creating a custom column editor associated to a RadGrid. I can modify items of the grid, delete them or adding new.
I have to avoid changing the code field while modifying the item. Is it possible to discriminate whether the ColumnEditor has been created pressing the update button or pressing the create new record button? So I can pass a parameter to my CustomEditor.
Thanks in advance.
Kind regards,
Dario Zanelli

Hello Dario,
Thank you for contacting us and for your question.
There are two possible options to address this.
First, from within the CreateColumnEditor server side handler, you can access the RadGrid1.EditIndexes and RadGrid1.MasterTableView.IsItemInserted properties to determine if the control is in edit mode (when the RadGrid1.EditIndexes collection has more than 0 elements), or it is in insert mode (RadGrid1.MasterTableView.IsItemInserted is true).
Alternatively, you can also subscribe to the ItemCommand event handler, which would be raised before CreateColumnEditor. There, you can determine the type of command (initInsert/Edit), and keep this in mind when the CreateColumnEditor is raised subsequently.
I hope one of these approaches is suitable for you. If any other questions aries, do let us know.
Kind regards,

Hello Yavor!
Thanks for the answer, very accurate. I am testing it, but I have another question: I have noticed that I can add a new item and at the same time edit an existing item.
I consider this quite dangerous for my application. Is it possibile to specify a property that avoid this? To allow only one of these two operations.
Regards,
Dario

Hello Dario,
You can go through the following help document which explains on how to switch between the Insert and Edit modes of the grid:

Hi Princy!
Thanks a lot for the answer, it is working properly.
Another one: how can I get the value of a column in the RadGrid item that I am editing (I know the index thanks to the property EditIndexes[0], I can edit only a column)?
Kind regards to all your team!
