DataBinding event handler not called for control in Template column

Hi,

I have a custom control type that implements ITemplate and is added to a GridTemplateColumn. I have added an event handler to the literal control that is part of the custom control.

    
                    public void InstantiateIn(System.Web.UI.Control container) 
        
                    { 
        
                        System.Web.UI.LiteralControl c = new System.Web.UI.LiteralControl(); 
        
                        c.DataBinding += new EventHandler(Button_DataBinding);

The first time the page loads, the event handler gets called. However, on Postback the event handler is not called.

Any ideas?

Thanks,
Dewang

Problems with DockPositionChanged

The setup we have is this: we have a DockZone filled with collapsed docks that the user drags out to one of three main dockZones on the page. When the dock is dropped into the new zone we are firing the DockPositionChanged event. This event flushes out the dock with all of the controls that it needs and loads the usercontrol into the dock. What we are seeing is whenever any event is triggered, the usercontrol inside the dock does an asynpostback or the expandCollapse event is fired so to is the DockPositionChanged event. Also we would really want the master list per say of docks to be repopulated with a fresh copy of the dock that was just dragged out and placed into one of the three zones.

CODE:

This is the master page that has the RadDockLayout

                    <asp:UpdatePanel ID="upl_Content" runat="server" UpdateMode="Conditional" >         
               <ContentTemplate>         
                  <telerik:RadDockLayout ID="RadDockLayout_Content" runat="server" onloaddocklayout="LoadDockLayout" onsavedocklayout="SaveDockLayout">           
                     <asp:ContentPlaceHolder ID="ContentPlaceHolderContent" runat="server"></asp:ContentPlaceHolder>         
                  </telerik:RadDockLayout>          
               </ContentTemplate>           
            <Triggers>         
            </Triggers>         
            </asp:UpdatePanel>         

Next we build the dockzone with all the available docks

                    protected void Page_Init(object sender, EventArgs e)         
            {         
                GetWidgets();         
            }         
                     

                            private void GetWidgets()         
                    // POPULATE WIDGET SELECTION ZONE         
                    {         
                        if (WidgetList.Controls.Count == 0)         
                        {         
                            ArrayList _wigetArray = new ArrayList();         
                            _wigetArray.Add("~/Prototype/Modules/CriticalPrinters/CriticalPrinters.ascx");         
                            _wigetArray.Add("~/Prototype/Modules/CriticalPrinters/CriticalPrinters.ascx");         
                            _wigetArray.Add("~/Prototype/Modules/SMIncidentAge/Services/SMIncidentAge.ascx");         
                            _wigetArray.Add("~/Prototype/Modules/Weather/WeatherControl.ascx");         
                     
                            int i = 0;         
                            foreach (String widgetURL in _wigetArray)         
                            {         
                                NCSBlackRadDock dock = new NCSBlackRadDock();         
                                dock.widgetIcon.ImageUrl = "~/Prototype/Modules/HttpWebRequest/Images/Config.png";         
                                dock.WidgetTitle.Text = string.Format("RadDock{0}", i);         
                                dock.Tag = widgetURL;         
                                dock.ID = string.Format("RadDock{0}", i);         
                                dock.UniqueName = Guid.NewGuid().ToString();         
                                dock.Text = dock.ID.ToString();         
                                dock.statusPanel.Visible = false;         
                                dock.widgetPanel.Visible = false;         
                                dock.EnableViewState = false;         
                                dock.Commands.Remove(dock.CloseCommand);         
                                dock.Commands.Remove(dock.ExpandCommand);         
                                dock.Commands.Remove(dock.SettingsCommand);         
                     
                     
                                dock.DockPositionChanged += new DockPositionChangedEventHandler(RadDock_DockPositionChanged);         
                                dock.AutoPostBack = true;         
                                dock.Collapsed = true;         
                     
                                WidgetList.Controls.Add(dock);         
                                i++;         
                            }         
                        }         
                    }         

Then finally the RadDock_DockPositionChanged

                            protected void RadDock_DockPositionChanged(object sender, DockPositionChangedEventArgs e)         
                    {         
                                 
                        Site1 pm = (Site1)Page.Master.Master;         
                        NCSBlackRadDock dock = (NCSBlackRadDock)sender;         
                     
                        if (dock.DockZoneID != e.DockZoneID)         
                        {         
                            try         
                            {         
                                dock.DockZoneID = e.DockZoneID;         
                                dock.Collapsed = false;         
                                dock.statusPanel.Visible = true;         
                                dock.widgetPanel.Visible = true;         
                                DockCloseCommand _CloseCommand = new DockCloseCommand();         
                                DockExpandCollapseCommand _ExpandCommand = new DockExpandCollapseCommand();         
                                dock.Commands.Add(_CloseCommand);         
                                dock.Commands.Add(_ExpandCommand);         
                                dock.Commands.Remove(dock.PreviewCommand);

Images always go at the top of the content placeholder

We've found when we use the image manager to add an image into the content placeholder in the middle of other text, the image is always inserted at the top of the HTML, and you have to drag it down manually to the correct place. Is this standard behaviour - is there any way to get the images to insert at the cursor position rather than right at the top?

Paging in Grid unable to display FirstPage/LastPage icons

I want to display next/previous AND FirstPage & LastPage.

I tried adding PagerStyle-Mode="NextPrevAndNumeric" & <PagerStyle Mode="NextPrevAndNumeric"></PagerStyle>.
However, it only displays next/previous and numbers. Not the FirstPage/LastPage.

How can I get it to display those 2 FirstPage/LastPage icons as well?

thanks

RadGrid in ToolTip on RadGrid

Hi all

The page I'm doing is a little complicated but I will try to explain what I need to achieve.
1. On the page there is an UpdatePanel ("upTimeRegs") with a RadGrid, where each row has an ID and a link.
2. When the mouse is over a link, a ToolTip ("ToolTipManager") should appear with contents based on the row's ID.
3. The content of the ToolTip is a user control ("ucTimeRegistrations") with another RadGrid ("RadGridTimeRegistrations") which has it's data bound in the NeedDataSource event handler
4. In the second RadGrid one of the columns is a RadComboBox. For each RadComboBox OnSelectedIndexChanged the main RadGrid should be updated

The problems I have:
1. The ToolTip is loaded fine the first time the mouse is over a link, but then when I hover a second link the content of the tooltip is not changed because the NeedDataSource event is not triggered.

2. The main RadGrid is not being updated when the selected index of a combobox is changed.

Here is some of the code I'm using:

    
            protected void ToolTipManager_OnAjaxUpdate(object sender, ToolTipUpdateEventArgs args) 
        
            { 
        
                Control ctrl = Page.LoadControl("~/UserControls/ucTimeRegistrations.ascx"); 
        
                args.UpdatePanel.ContentTemplateContainer.Controls.Add(ctrl); 
        
                ucTimeRegistrations TimeRegistrations = (ucTimeRegistrations)ctrl; 
        
                TimeRegistrations.TaskID = Convert.ToInt32(args.Value); 
        
            } 
        
            public partial class ucTimeRegistrations : UserControl 
        
            { 
        
                public int TaskID; 
        
                protected void Page_Load(object sender, EventArgs e) 
        
                { 
        
                } 
        
                protected void RadGridTimeRegistrations_NeedDataSource(object  source, GridNeedDataSourceEventArgs e) 
        
                { 
        
                    RadGTimeRegistrations.DataSource = TimeRegistrationHandler.GetTimeRegistrationsFromDB(TaskID); 
        
                } 
        
                protected void RadComboBoxActivity_SelectedIndexChanged(object sender, RadComboBoxSelectedIndexChangedEventArgs e) 
        
                { 
        
                    RadComboBox rcbActivity = (RadComboBox)sender; 
        
                    GridDataItem Row = (GridDataItem)rcbActivity.Parent.Parent; 
        
                    if (Row != null) 
        
                    { 
        
                        int TimeRegistrationID = Convert.ToInt32(Row["TimeRegistrationID"].Text); 
        
                        int ActivityID = Convert.ToInt32(e.Value); 
        
                        TimeRegistrationHandler.UpdateTimeRegistration(TimeRegistrationID, ActivityID); 
        
                        UpdatePanel upTimeRegs = (UpdatePanel) FindControlRecursive(Page, "upTimeRegs");

                        upTimeRegs.Update(); 
        
                    } 
        
                }

                private Control FindControlRecursive(Control rootControl, string Id)

                {

                    if (rootControl.ID == Id)

                        return rootControl;

                    foreach (Control childControl in rootControl.Controls)

                    {

                        Control foundControl = FindControlRecursive(childControl, Id);

                        if (foundControl != null) return foundControl;

                    }

                    return null;

                }
        
            }

Language problems

Hi!

We are translating the editor (v7.2.0.0 ) to swedish,danish,finnish and norwegian.

Swedish, Danish and Finnish all works fine when setting RadEditor.Language to "se", "da", "fi".

But when I try to set it to "no" for norwegian I get an javascript error
Line: 434
Error: 'localization_no' is undefined

Ive tried to set the language to "nn-NO" and "nb-NO" and also renamed the folder in localization but I still get an error.

Any ideas? I know we are using and old version of the editor but updating it is not possible due to some massive integrations we have done with the editor.
