There is no capability to display CommandColumn items in the Adaptive mode if the Adaptive Detail Layout is customized

In the scope of the fix applied in this thread, we added the following overload of the AdaptiveDetailLayoutProperties.Items.AddCommandItem method with the ColumnName parameter.
Use this method to add command columns to the Adaptive Detail Layout:

C#
//Layout Items configuration  
settings.SettingsAdaptivity.AdaptiveDetailLayoutProperties.Items.AddCommandItem("CommandColumnEdit");  
 settings.SettingsAdaptivity.AdaptiveDetailLayoutProperties.Items.AddColumnItem("ProductName");  
settings.SettingsAdaptivity.AdaptiveDetailLayoutProperties.Items.AddColumnItem("CategoryID");  
settings.SettingsAdaptivity.AdaptiveDetailLayoutProperties.Items.AddColumnItem("QuantityPerUnit");  
settings.SettingsAdaptivity.AdaptiveDetailLayoutProperties.Items.AddColumnItem("UnitPrice");  
 settings.SettingsAdaptivity.AdaptiveDetailLayoutProperties.Items.AddCommandItem("CommandColumnDelete");  

Take special note that it is necessary to specify names for all required command columns to use this method. For example, if you create command columns using the GridViewSettings.Columns.Add  method, then you can specify command columns's names as shown below:

C#
// columns definition  
settings.Columns.Add(new MVCxGridViewCommandColumn() { Name = "CommandColumnEdit", ShowEditButton = true, Visible = true });  
 settings.Columns.Add(c => {  
    c.FieldName = "ProductName";  
    //..........................  
});  
settings.Columns.Add(c => {  
    c.FieldName = "CategoryID";  
    //..........................  
});  
settings.Columns.Add(c => {  
    c.FieldName = "QuantityPerUnit";  
    //..........................  
});  
settings.Columns.Add(c => {  
    c.FieldName = "UnitPrice";  
    //..........................  
});  
settings.Columns.Add(new MVCxGridViewCommandColumn() { Name = "CommandColumnDelete", ShowDeleteButton = true, Visible = true });  

If you enable command columns using the GridViewSettings.CommandColumn parameters, then you can specify a command column name as shown below:

C#
settings.CommandColumn.Visible = true;  
settings.CommandColumn.ShowDeleteButton = true;  
settings.CommandColumn.ShowEditButton = true;  
settings.CommandColumn.Name = "CommandColumn";  

C#
settings.SettingsAdaptivity.AdaptiveDetailLayoutProperties.Items.AddCommandItem("CommandColumn");
