Event not fire by button when dynamicaly created into a RadOrgChart item

[Arnaud]

Hi,

I try to generate an OrgChart dynamically, for do that, I need to add actions to the orgChart item (by RadButton).

In my first POC, I try the programm below.

<%@ Control language="C#" Inherits="DotNetNuke.Modules.Quanteam.ContractModule.View" AutoEventWireup="false"  Codebehind="View.ascx.cs" %>
<%@ Register assembly="System.Web.Entity, Version=3.5.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" namespace="System.Web.UI.WebControls" tagprefix="asp" %>
<%@ Register TagPrefix="telerik" Assembly="Telerik.Web.UI" Namespace="Telerik.Web.UI" %>

<asp:MultiView ID="multiView" runat="server">
    <asp:View ID="ViewContractDetail" runat="server">
        <telerik:RadOrgChart runat="server" ID="radOrgChart">
            <Nodes>
                <telerik:OrgChartNode>
                    <ItemTemplate>
                        <div style="background-color: Red; height: 80px; width: 180px;">
                            <telerik:RadButton ID="TestBtnOrgChart" Text="click : 0" runat="server"
                                OnClick="onClick_Handler"
                                ValidationGroup="ParamValidationGroup"
                                ButtonType="LinkButton" BorderStyle="None">
                                <Icon PrimaryIconUrl="~/images/Add.gif" PrimaryIconLeft="5px" />
                            </telerik:RadButton>
                        </div>
                    </ItemTemplate>
                    <GroupItems>
                        <telerik:OrgChartGroupItem Text="Click for Test" />
                    </GroupItems>
                </telerik:OrgChartNode>
        </telerik:RadOrgChart>
    </asp:View>
</asp:MultiView>

 

private void Page_Load(object sender, System.EventArgs e)
        {
            try
            {
                System.Web.UI.WebControls.View view = FindControl("ViewContractDetail") as System.Web.UI.WebControls.View;
                multiView.SetActiveView(view);

                //----------------------------------------------------
                // RadOrgChart
                //----------------------------------------------------

                var nodeContract = new OrgChartNode();
                radOrgChart.Nodes.Add(nodeContract);

                OrgChartGroupItem topContract = new OrgChartGroupItem() { Template = new MyTemplate("btnOrgChart1") };
                nodeContract.GroupItems.Add(topContract);

                var node = new OrgChartNode();
                topContract.Node.Nodes.Add(node);

                OrgChartGroupItem missionNode = new OrgChartGroupItem() { Template = new MyTemplate("btnOrgChart2", onClick_Handler) };
                node.GroupItems.Add(missionNode);

                //----------------------------------------------------
                // RadButton
                //----------------------------------------------------

                RadButton radBtn = new RadButton();
                radBtn.ID = "btn_1";
                radBtn.Text = string.Format("click : {0}", 0);
                radBtn.Click += onClick_Handler;
                view.Controls.Add(radBtn);
            }
            catch (Exception exc) //Module failed to load
            {
                Exceptions.ProcessModuleLoadException(this, exc);
            }
        }

        class MyTemplate : ITemplate
        {
            private string _id;
            private System.EventHandler _onClick;

            public MyTemplate(string id)
            {
                _id = id;
                _onClick = onClick_Handler;
            }

            public MyTemplate(string id, System.EventHandler onClick)
            {
                _id = id;
                _onClick = onClick;
            }

            public void InstantiateIn(Control container)
            {
                RadButton radBtn = new RadButton();
                radBtn.ID = _id;
                radBtn.Text = string.Format("click {1} : {0}", 0, _id);
                radBtn.Click += _onClick;
                container.Controls.Add(radBtn);
            }

            protected void onClick_Handler(object sender, System.EventArgs e)
            {
                RadButton radBtn = sender as RadButton;
                radBtn.Text = string.Format("click {1} : {0}", Convert.ToInt32(radBtn.Text.Split(':')[1]) + 1, _id);
            }
        }

        protected void onClick_Handler(object sender, System.EventArgs e)
        {
            RadButton radBtn = sender as RadButton;
            string[] items = radBtn.Text.Split(':');

            radBtn.Text = string.Format("{0} : {1}", items[0], Convert.ToInt32(items[1].Trim()) + 1);
        }

 

When I try this program, the button created into the OrgChart by API call the Page_Load handler, but not the associated click handler.
Even if the handler came from the view or from the custom ITemplate class.

The two buttons of control :
- generated with the ASX and inside of the OrgChart
- generated with the API and outside of OrgChart
works normally.

Why my two Button generated with API into the OrgChar seems to don't call the Click event.

For information, I begin on ASP.Net since few week.

Thanks for your help.

Nobody has an idea for resolve or work around this issue :( ?

Hello Arnaud,

Indeed, the click event of the RadButtons inside the RadOrgChart item is not firing . We need more time to investigate the problem in details. You will be notified as soon as the encountered behavior is inspected.

All the best,

Hi Arnaud,

We logged the issue and it is going to be fixed for the upcoming Server Pack 1 (in the middle of April).
If you bind the control and do not add nodes and items dynamically everything should be working correct with the latest internal build of our controls. If you require we can let you know when the fix is available (in case it is before the mentioned date) so that you can download it and test it.

As a sign of gratitude for pointing this out I updated your points.

Hi, do you have any news about this? im facing the same problem and i need to resolve it asap

thanks!

[Peter Filipov]

Hello Christian,

We fixed the issue. Could you please try to test your project with the latest version of our controls - Q1.2012 Service Pack 1. In case you still experience problems, please open a new support thread and send me your project for a local test.

All the best,

I'm using build 2012.1 411 but I'm finding generated buttons do not post back (they post back after a second click though). Is it supposed to be for this build? Is this SP1? I've looked around and I can't see a download for ASP.NET AJAX 2012 SP1 controls.

Hello Ruairi,

I am writing to confirm that the 2012 SP1 version is 2012.1.411 and the fix should be available. Could you please open a new support ticket and send us your project for local test? This will helps us resolve the issues faster.
