[Solved] Setting a Column to be Editable only for Insert

[Derrick]

I have a requirement to set a column (call it TitleValue) to be readonly in editing mode, but NOT in Insert. The idea is to be able to add new values in an insert, but once the value is in the grid, not being able to edit it. For this example, I have setup a EditorTemplate for this column to be a DropDown. So far, I am only able to make BOTH edit and insert either readonly or not. I want the Insert mode to be editable, but not the Edit mode (Edit should be readonly).

Hello Derrick,

Basically to disable the DropDown menu in edit mode only, you need to hook up a JavaScript function to the OnEdit client event. The function itself should check if the mode is "edit" and disable the DropDown list.

e.g.

//...
.ClientEvents(events=> events.OnEdit("DisableDropdown"))

JavaScript:

function DisableDropdown(e) {
        if (e.mode == "edit") {
            $('#DropDownID').attr('disabled', 'disabled');
        }
}

I hope this answers your question.
