[Tactem]

Hi guys,

I have a Desktop with one module.
If i click on a specific button, i call a direct method function in Desktop.aspx.
this function dynamic load an another module( in autorun = true).

test.ascx use also DevExpress component.

I don't fire Page_Load from this module.

The module is show.

Desktop.aspx

[DirectMethod]
public void test()
{
    _test ucSimpleControl = LoadControl("~test.ascx") as _test;
    DesktopModuleProxy control = Ext.Net.Utilities.ControlUtils.FindControl<Ext.Net.DesktopModuleProxy>(ucSimpleControl);
    DesktopMain.AddModule(control.Module);
}

Test.ascx

<ext:DesktopModuleProxy ID="DesktopModuleProxy1" runat="server">
    <Module ModuleID="tab-win" AutoRun="true">
        <Shortcut Name="test" />
        <Launcher Text="test" />
        <Window>
            <ext:Window ID="WindowsView" runat="server" Title="View" BodyBorder="1"

                        <Content>
                            <dx:ASPxGridView ID="Grid" runat="server" Width="100%" DataSourceID="dataSource"
                                AutoGenerateColumns="False" KeyFieldName="0Id" OnInit="windows_init">
                                <Columns>
                                </Columns>
                                <Settings ShowFilterRow="True" ShowFilterRowMenu="true" ShowVerticalScrollBar="true"
                                    ShowHorizontalScrollBar="true" VerticalScrollBarStyle="Virtual" />
                            </dx:ASPxGridView>
                            <asp:SqlDataSource ID="dataSource" runat="server" EnableCaching="true"></asp:SqlDataSource>
                        </Content>
                    </ext:Panel>
                </Items>
            </ext:Window>
        </Window>
    </Module>
</ext:DesktopModuleProxy>

Test.ascx.cs

protected void Page_Load(object sender, EventArgs e)
        {
            dataSource.ConnectionString = "ConnectionString";
            dataSource.SelectCommand = "SELECT * FROM table";
            if (!IsPostBack)
            {
                display();
            }
            else if (Session["Colonne"] != null) _listeColumn = (List<String>)Session["Colonne"];
        }

Hi @Tactem,

An AddModule method retrieves a DesktopModuleProxy only from a user control. It doesn't register a user control on a page. So, its life cycle is not executed.

Currently, we can suggest to handle a Window's OnLoad event. You can get controls using a FindControl method.

We are looking at a possibility to support an Ext.Net.IDynamicUserControl interface for Desktop. An example of using this interface is here:
https://examples2.ext.net/#/Loaders/...Direct_Method/

See a DynamicItems.ascx file.

Test in my DynamicItems.ascx (I'm just the wrong extension by post). I can't use FindControl but i don't now ID of column.

display method

   Configuration.getInstance().NomTable = "TableTemp";
   List<String> listeColonne = GenerateData.getInstance().getColonne();
   foreach (String colonne in listeColonne)
   {
      if (!colonne.ToLower().Contains("_id") && !colonne.ToLower().Contains("0id"))
      {
         AddColumnDX(colonne, colonne);
      }
   }

private void AddColumnDX(String nomColonne, String type)
        {
            try
            {
                GridViewDataTextColumn column = new GridViewDataTextColumn();
                column.Caption = nomColonne;
                column.Visible = true;
                column.FieldName = type;
                Grid.Columns.Add(column);
            }
            catch (Exception err)
            {
                throw err;
            }
        }

[Daniil]

We don't understand well what exactly a problem. Could you clarify, please?

[Tactem]

[Daniil]

Thank you for the details.

Well, and the problem is the fact that the Page_Load is not executed, right?

Our suggestion in the post #2 was to use a Window OnLoad event instead of Page_Load. Please clarify did you try it?

Opened an Issue to track this defect, see

I use tabPanel with directMethod and javascript call now and call aspx instead of ascx

function addTabs(type, guid)
{
    try {
        var index = Ext.getCmp('TabPanel').items.length + 1;
        var tab = Ext.getCmp('TabPanel').add(
    {
        id: "Tab" + index,
        title: type,
        closable: true,
        border: false,
        loader:
        {
            url: "../modules/module.aspx?i=" + index + "&g=" + guid,
            renderer: "frame"
        }
    });
        Ext.getCmp('TabPanel').setActiveTab(tab);
    }
    catch (err) {
        App.direct.UnhandledException(err);
    }
}

Thank you for the update. It is good.

We will keep this thread opened to track an implementation of this feature.

Well, a Desktop works directly with a DesktopModuleProxy. It has no access to a user control. So, we can't call its methods in this case.

So, we are closing a ticket.

Fortunately, a developer is able to call a user control's method himself after a LoadControl call.
