GridView for ASP.NET MVC - How to enable or disable the cell edit functionality in batch mode based on a condition

This example demonstrates how to use the check box state to enable or disable the grid's cell edit functionality in batch edit mode.

Overview

Follow the steps below:

1. Create the Grid View control and populate it with columns. Set the grid's SettingsEditing.Mode property to Batch to enable the batch edit mode. Add a command column and set its ShowNewButtonInHeader and ShowDeleteButton properties to true.

   @Html.DevExpress().GridView(settings => {
       // ...
       settings.SettingsEditing.Mode = GridViewEditingMode.Batch;
       settings.CommandColumn.Visible = true;
       settings.CommandColumn.ShowNewButtonInHeader = true;
       settings.CommandColumn.ShowDeleteButton = true;
       // ...
   }).Bind(Model).GetHtml()

2. Add a check box and handle its client-side CheckedChanged event. In the handler, get the current state of the check box and assign the state to a flag variable.

   @Html.DevExpress().CheckBox(settings => {
       settings.Name = "AllowEditCB";
       settings.Text = "Allow Editing";
       settings.Properties.ClientSideEvents.CheckedChanged = "OnAllowEditChanged";
   }).GetHtml()

   var allowEdit = false;
   function OnAllowEditChanged(s, e) {
       allowEdit = s.GetValue();
   }

3. Handle the grid's client-side BatchEditStartEditing, BatchEditRowInserting, and BatcshEditRowDeleting events. In the handler, cancel the current edit operation based on the flag variable value.

   @Html.DevExpress().GridView(settings => {
       // ...
       settings.ClientSideEvents.BatchEditRowDeleting = "OnEditing";
       settings.ClientSideEvents.BatchEditRowInserting = "OnEditing";
       settings.ClientSideEvents.BatchEditStartEditing = "OnEditing";
   })

   function OnEditing(s, e) {
       e.cancel = !allowEdit;
   }
