How to disable/enable button based on a value in the grid cell ?

[faujong]

I use Ext.net iIn my Index.cshtml page.
I have a grid and a button called BtnEdit in my page.
One of the columns in the grid is called "Match".
I would like to disable BtnEdit when "Match" = "N", and enable it when "Match" = "Y" .
How can I do that ?
Thank you.

This is a snippet of my code:

@(X.Viewport().Layout(LayoutType.Fit)
            .Items(
            X.GridPanel().ID("GridPanel1").MarginSpec("1 1 1 1").Cls("cust-grid")
            .ColumnModel(
                X.RowNumbererColumn().Width(35).Sortable(false).Hideable(false),
                X.NumberColumn().Text("ID").DataIndex("ID").Width(80).Format("#").Align(Alignment.Right).Hideable(false).Groupable(false).Filter(X.NumberFilter()),
		X.Column().Text("Match").ID("Match").DataIndex("Match").Width(85).Align(Alignment.Center).Hideable(false).Groupable(false).Filter(X.ListFilter().Options("Y,N")),
	    )		
            .Listeners(ls => ls.Select.Handler = @"var store=App.Store1; var combo=App.NoItem; store.pageSize=combo.getValue(); store.reload();")
            .Plugins(X.GridFilters())
            .View(X.GridView().StripeRows(true).TrackOver(false).GetRowClass(r=>r.Fn="getRowClass"))
            .SelectionModel(X.RowSelectionModel().Mode(SelectionMode.Single))
            .TopBar(
                X.Toolbar().ID("Toolbar1").MinHeight(35)
                    .Items(
                        X.Button().ID("BtnEdit")
                            .Text("Edit").Icon(Icon.GroupEdit)                            
                            .Handler("var rec=App.GridPanel1.selModel.getSelection()[0]; if(rec) { App.Form1.getForm().loadRecord(rec); App.WindowEdit.show(this);} else alert('Please select row first!')")
