[CLOSED] Loading data in gridpanel through WebService in sublassed window

[smart+]

Hello,

I created subclassed ext.net window control and want use web service for populating gridpanel inside this window,
but grid not load data. I don't see what is wrong and where I made mistake.
This control I call in my page with following code:

   new Test.UI.TestWindow().Render(this.Page.Form.ClientID,RenderMode.RenderTo);

Code for subclassed window control is following:

namespace Test.UI
 
{
 
  public class TestWindow : Ext.Net.Window    
 
  {
 
    public TestWindow()
 
    {
 
           this.IDMode = IDMode.Explicit;
 
           this.ID = "frmTest";
           this.Width = 600;
           this.Height = 600;
           this.Layout = "FitLayout";
           this.Padding = 5;
 
this.Items.Add(new GridPanel
            {
                ID = "gridCourses",
                IDMode = IDMode.Explicit,
                Height = 300,
                AutoExpandColumn = "caption",
                Store=
                {
                new Store
                    {
                        ID = "strCalcW",
                        IDMode = IDMode.Explicit,
                        RemoteSort = true,
                        Proxy =
                        {
                            new HttpProxy{Json=true,Method= HttpMethod.POST,Url="../Shared/GetStudyCourses.asmx/CoursePaging"}
                        },
                        AutoLoadParams =
                        {
                            new Parameter{Name="start",Value="0",Mode=ParameterMode.Raw},
                            new Parameter{Name="limit",Value="20",Mode=ParameterMode.Raw}
                        },
                        BaseParams =
                        {
                            new Parameter{Name="studycode",Value="SS",Mode=ParameterMode.Raw},
                            new Parameter{Name="semestar",Value="0",Mode=ParameterMode.Raw}
                        },
                        Reader =
                        {
                            new JsonReader
                            {
                                IDProperty="idrec", 
                                Root = "d.Data",
                                TotalProperty="d.TotalRecords",
                                Fields=
                                {
                                    new RecordField{Name="idrec"},
                                    new RecordField{Name="caption"},
                                    new RecordField{Name="studycode"}
                                }
                            }
                        },
                        SortInfo = { Field = "caption", Direction = SortDirection.ASC }
                    }
                },
                ColumnModel =
                {
                    ID = "colCalcW",
                    IDMode = IDMode.Explicit,
                    Columns = 
                    { 
                        new RowNumbererColumn{Header="No.",Width=30,ColumnID="col1"},
                        new Column{Header="Caption",ColumnID="caption",DataIndex="caption",Sortable=true,MenuDisabled=true},
                        new Column{Header="",Width=30,ColumnID="col3",DataIndex="studycode",Sortable=true,MenuDisabled=true}
                    }
                },
                LoadMask = { ShowMask = true, Msg = "Loading..." },
                SelectionModel = { new CheckboxSelectionModel { ID = "id", IDMode = IDMode.Explicit } },
                BottomBar = { new PagingToolbar { PageSize = 20 } }
            });
 
  }
 
}

Please can you look what is wrong.

Hi,

Please post response from webservice

Hi,

I looked through Fiddler and I don't have any response from web service when is subclassed window shown.
Also, when I click on refresh button in pagging toolbar in gridpanel, nothing happen.
This grid and store not call web service for loading data.
Other test which I made is when I copy web service url path in address bar and call CoursePaging method with base parameters, I get all my data.

Does exist some other test what I can make?

Hi Vladimir,

How I can test or solve this issue?

Hi,

I am out of ideas, if HttpProxy is defined then a request must be initiated
I guess that js error is occured before loading

Can you clarify is SS js variable is defined in your page

new Parameter{Name="studycode",Value="SS",Mode=ParameterMode.Raw},

You use Raw mode, it means that value will not be wrapped by quotes
May be you need to use ParameterMode.Value?

Yes, this is solution. I changed ParameterMode into Value and all work very nice.

You are the best.
Thank you very much.
