RadDockingZone1.Controls.Clear() is not working.

[Animesh Dey]

hi,

I m developing a project with classical Rad Controls. I got problem when i m working with RadDocking object. 

Scenario:

1. Load Parent Node first to radDocking objects

2. Load Child to the same RadDockingZone when any parent id click.

I can load Parent node first having no problem. But when i try to load children of that parent, RadDockingZone is not clear and no children is viewed. 

<form id="form1" runat="server">

        <div>

            <cc1:RadDockingManager ID="RadDockingManager1" runat="server" />

            <cc1:RadDockingZone ID="RadDockingZone1" runat="server" Width="100%" Height="100%"

                DockEnabled="true" Type="Horizontal">

                </cc1:RadDockingZone>

        </div>

        

        <script type="text/javascript">

        function LoadRelatedDiscipline(ParentID)

        {

            var ajaxManager = <%= RadAjaxManagerDefault.ClientID %> 

            ajaxManager.AjaxRequest(ParentID); 

        }

        </script>

        

        <radW:RadWindowManager ID="RadWindowManager2" runat="server" Skin="Office2007" Behavior="None"

            VisibleStatusbar="false" UseEmbeddedScripts="false">

        </radW:RadWindowManager>

        <radA:RadAjaxManager ID="RadAjaxManagerDefault" runat="server" DefaultLoadingPanelID="AjaxLoadingPanel1"

            OnAjaxRequest="RadAjaxManagerDefault_AjaxRequest" UseEmbeddedScripts="False">

        </radA:RadAjaxManager>

        <radA:AjaxLoadingPanel ID="AjaxLoadingPanel1" runat="server" Height="75px" Transparency="10"

            Width="75px">

            <asp:Image ID="Image1" runat="server" AlternateText="Loading..." BackColor="Transparent"

                ImageUrl="~/RadControls/Ajax/Skins/Default/loading.gif" />

        </radA:AjaxLoadingPanel>

    </form>

protected void Page_Load(object sender, EventArgs e)

    {

        if (!IsPostBack)

        {

            this.LoadDockObjects(null);           

        }

    } 

private void LoadDockObjects(int? parentId)

    {

DataTable dt = new DataTable();

if( parentID == null)

{

dt = LoadAllParents();

} 

else

{

LoadChildrent(parentId);

}       

        foreach (DataRow oRow in dt.Rows)

        {

            RadDockableObject obj = new RadDockableObject();

            obj.ID = string.Format("ID{0}", oRow["ID_NUM"]);

            obj.Text = oRow["DETAIL"].ToString();

            obj.DockingMode = RadDockingModeFlags.AlwaysDock;

            obj.Width = Unit.Pixel(600);

            obj.Height = Unit.Pixel(300);

            Oracle_ControlLibrary_ucRD2l customControl = (Oracle_ControlLibrary_ucRD2l)LoadControl("~/Oracle/ControlLibrary/ucRD2l.ascx");

            customControl.PatientKey = patientKey;

            customControl.DisCode = oRow["ID_NUM"].ToString();

            obj.Container.Controls.Add(customControl);

            RadDockingZone1.Controls.Add(obj);

            this.VisitedRDHandler(oRow["DETAIL"].ToString());

        }

    }

protected void RadAjaxManagerDefault_AjaxRequest(object sender, AjaxRequestEventArgs e)

    {

        if (e.Argument != string.Empty)

        {

            int? patientId = Convert.ToInt32( e.Argument);

            this. LoadDockObjects(patientId);

        }

    } 

I did not find any solution of that problem. Please help....

Hi,

I solve that problem by modifying RadAjaxManager Setting. 

Solution:

<radA:RadAjaxManager ID="RadAjaxManagerDefault" runat="server" DefaultLoadingPanelID="AjaxLoadingPanel1"

            OnAjaxRequest="RadAjaxManagerDefault_AjaxRequest" UseEmbeddedScripts="False">

            <AjaxSettings>

            <radA:AjaxSetting AjaxControlID="RadAjaxManagerDefault">

                <UpdatedControls>

                    <radA:AjaxUpdatedControl ControlID="RadDockingManager1" />

                    <radA:AjaxUpdatedControl ControlID="RadDockingZone1" />

                </UpdatedControls>

            </radA:AjaxSetting>

        </AjaxSettings>

        </radA:RadAjaxManager>

But faced new problem.

Problem: 

My DockObject Contain a user control which also contain a asp:GridView to view node information. 

First time when the parent node are displayed, its work fine. But got problem when the child information is loaded. 

Those Grid column is viewing empty value which are "TemplateField". 

Is there any solution of that problem??
