[Solved] Hide field in popup

[Amjad]

How do I hide a field in the standard popup window when Add button is clicked?

Hello Amjad,

The following example shows how this can be achieved: https://blazorrepl.telerik.com/mfuXPgFI22CtIgay37 

Note that the Quantity field is visible in the Edit popup, but not in the Add popup. 

The approach requires using a FormTemplate, in which you can check whether the popup is for adding a new record or for editing an existing record. This information is available in the template through the context: formContext.IsNew

Then you can add conditional logic to the template, so that the respective field shows only in the Edit popup and remains hidden in the Add popup.

Per the linked example, it looks like using a TelerikForm in the FormTemplate actually breaks the built in grid Update event. You have to put effort in to manually manage the edited item and popup state. Kind of a pita for what I assume is a common use case, but doable.
