When creating grid. How I can make certain columns read only

[Salma]

HI Using asp.net mvc .net (not core).  I want to disable columns for edit. Person can read it but cannot overrite it.  How I can do that?

Hello Amir,

This is possible when using Inline or InCell editing mode. You can specify a column as a read-only in the Grid DataSource model configuration with the 'Editable(false)' option.

.DataSource(dataSource => dataSource
    .Ajax() // or .Server()
    .Model(model =>
    {
        // Declare a model field and make it readonly
        model.Field(p => p.UnitPrice).Editable(false);
    })
)

Thanks for the suggestion. but what if I am using the popup.  Can't I hide or disable when using the popup?

I read on other thread and tried to implment the below. 

The recommended resoution is working but it hides the column from the main grid.

        [ScaffoldColumn(false)]
        public int Id { get; set; }

I want to show the column "Date Entetred' on the grid but I want to hide it when user editing the row or when user saving a new data.  

Similarly, I want to make a read only field when user is editing or saving.  For example, I want to show the grid with the UserId,

but i do not want to make it readonly.  I used the below code but it is not working for popup.  

I used to disable the field model.Field(p => p.​ID).Editable(false);

Hi,

By default, the 'PopUp editor' is generating fields for each property of the Model passed to the Grid based on its value. 

If a custom editor is needed, I recommend you to review the following demo:

https://github.com/telerik/ui-for-aspnet-mvc-examples/tree/master/grid/custom-popup-editor

It demonstrates how to implement a custom editor and how to configure the Grid to use it.

This way, you'll have full control over which fields to be shown and how to be shown.
