Grid View for ASP.NET Web Forms - 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 GridViewCommandColumn and set its ShowNewButtonInHeader and ShowDeleteButton properties to true.

   <dx:ASPxGridView ID="ASPxGridView1" runat="server" KeyFieldName="ID" ...>
       <SettingsEditing Mode="Batch" />
       <Columns>
           <dx:GridViewCommandColumn ShowNewButtonInHeader="true" ShowDeleteButton="true" />
           <!-- ... -->
       </Columns>
   </dx:ASPxGridView>

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

   <dx:ASPxCheckBox ID="ASPxCheckBox1" runat="server" Text="Allow edit">
       <ClientSideEvents CheckedChanged="OnAllowEditChanged" />
   </dx:ASPxCheckBox>

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

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

   <dx:ASPxGridView ID="ASPxGridView1" runat="server"  ...>
       <!-- ... -->
       <ClientSideEvents BatchEditStartEditing="OnEditing" BatchEditRowDeleting="OnEditing" BatchEditRowInserting="OnEditing" />
   </dx:ASPxGridView>

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