RowExpander with command column not calling direct method.

[Mr.Techno]

Hi
I am using a gridpanel in a window with rowexpander plugin.
My expanding row, sub gridpanel has the command column. When the user clicks on the command column, i am trying to call a directmethod. but i am getting a error like 'directmethodname+ not a function'..

I implemented this in my master page.

please find the below code where i am calling directmethod.

protected void BeforeExpand(object sender, DirectEventArgs e)
    {
        string id = e.ExtraParams["id"];

        Store store = new Store { ID = "StoreRow_" + id };

        JsonReader reader = new JsonReader();
        reader.IDProperty = "ProjectId";
        reader.Fields.Add("ProgramId", "ProjectId", "ProjectName");
        store.Reader.Add(reader);

        DataTable dt = prjManager.GetProjectsData();

        store.DataSource = dt;
        store.DataBind();

        this.RemoveFromCache(store.ID);
        store.Render();
        this.AddToCache(store.ID);

        GridPanel grid = new GridPanel
        {
            ID = "GridPanelRow_" + id,
            StoreID = "{raw}StoreRow_" + id,
            Height = 200,
            LoadMask = { ShowMask=true,Msg="Loading..."}
        };

        grid.ColumnModel.Columns.Add(new Column
        {
            Header = "Name",
            DataIndex = "ProjectName",
            Width = 300
        });

       
        var commandColumn = new Ext.Net.CommandColumn
        {
            Width = 200,
        };

        var gridCommand = new Ext.Net.GridCommand
        {
            CommandName = "someName",
            Icon = Icon.ChartPie,
            Text = "some Text"
        };

        commandColumn.Commands.Add(gridCommand);
        grid.ColumnModel.Columns.Add(commandColumn);

        grid.Listeners.Command.Handler = "CompanyX.GridPanel1Click()";

        grid.ColumnModel.ID = "GridPanelRowCM_" + id;
        
        //grid.BottomBar.Add(new PagingToolbar { ID="paging"+id,PageSize=10,HideRefresh=true});
        grid.View.Add(new Ext.Net.GridView { ID = "GridPanelRowView_" + id, ForceFit = false });

        //important
        X.Get("row-" + id).SwallowEvent(new string[] { "click", "mousedown", "mouseup", "dblclick" }, true);

        this.RemoveFromCache(grid.ID);
        grid.Render("row-" + id, RenderMode.RenderTo);
        this.AddToCache(grid.ID);

    }

    [DirectMethod(Namespace="CompanyX")]
    public void GridPanel1Click()
    {
        X.Msg.Notify("test", "clicked").Show();
    }

This is the part of the code where you can observe i am trying to call directmethod when user clicks on commnad column.

I also want to send entire row values to directmethod including command name.

Please help me... why my direct method is not calling...why its throwing error?
