Error on client-side event when registering it on server-side

Hi,

I'm creating dynamic docks and zones as well. While creating docks I register 2 client-side events on server side -- OnClientDockPositionChanging and OnClientDragStart. OnClientDockPositionChanging works fine but when OnClientDragStart throws javascript error.

    
            function OnClientDockPositionChanging(sender, eventArgs) 
        
            { 
        
               alert("Stop"); 
        
               eventArgs.set_cancel(true); 
        
            } 
        
            function OnClientDragStart(sender, eventArgs) 
        
            { 
        
               alert("Stop Drag"); 
        
               eventArgs.set_cancel(true); 
        
            }

    
            private RadDock CreateRadDockFromState(DockState state, int number) 
        
                { 
        
                    RadDock dock = new RadDock(); 
        
                    dock.ID = string.Format("RadDock{0}", number); 
        
                    dock.ApplyState(state); 
        
                    dock.Visible = !state.Closed; 
        
                    dock.Commands.Add(new DockPinUnpinCommand()); 
        
                    dock.OnClientDockPositionChanging = "OnClientDockPositionChanging"; 
        
                    dock.OnClientDragStart = "OnClientDragStart"; 
        
                    return dock; 
        
                } 
        
                private RadDock CreateRadDock(int id) 
        
                { 
        
                    RadDock dock = new RadDock(); 
        
                    dock.ID = string.Format("RadDock{0}", id); 
        
                    dock.Title = txtTitle.Text; 
        
                    dock.Text = txtText.Text + "<br>" + dock.ID; 
        
                    dock.UniqueName = Guid.NewGuid().ToString(); 
        
                    dock.Width = Unit.Pixel(300); 
        
                    dock.Commands.Add(new DockPinUnpinCommand()); 
        
                    dock.OnClientDockPositionChanging = "OnClientDockPositionChanging"; 
        
                    dock.OnClientDragStart = "OnClientDragStart"; 
        
                    return dock; 
        
                }

Captcha enter button

Hey Guys;

Great start on the Captcha function.

What is the best recommendation for hooking the Captcha submission to a keyboard enter click, rather than verify code?

RadGrid + RadAjaxManager - Show LoadingPanel in Grid

I am using a RadGrid successfully with the RadAjaxManager and a RadAjaxLoadingPanel. When I update my grid, it disappears for a second and shows the Loading Panel. I noticed in a Telerik demo that they had the grid lighten up and showed the loading panel right within the grid. I can't figure out how they did that - can anybody point me in the right direction?

Here is the sample: http://demos.telerik.com/aspnet-ajax/grid/examples/performance/linq/defaultcs.aspx

[Solved] delete link on radgrid performs delete function on edit mode

Hi,
I have a RadGrid with delete and edit link as one of its columns. If i edit a record, it opens in Editform on grid.
When working on edit form of rad grid if I click on Delete link on radgrid at the back of editform, it still performs the delete operation
even though one record is in edit mode.
following is the way by which I am declaring the Delete link.

<telerik:GridTemplateColumn UniqueName="DeleteColumn" ItemStyle-VerticalAlign="Middle" ItemStyle-HorizontalAlign="Center">

<asp:LinkButton runat="server" CausesValidation="false" OnClientClick ="if (confirm('Are You Sure You Wish To Delete This Item?'))return true; else return false;" CommandName="Delete" Text="Delete" ID="btnDelete" ForeColor="Blue"></asp:LinkButton> </ItemTemplate>

</telerik:GridTemplateColumn>

Please guide me how i can avoid this?

Thanks

Issue with PanelBar control

I have an issue adding a user control to the RadPanelBar (ajax) Q3 2008 version.

My markup is as follows:

<div style="margin-left: 20px;">
        <telerik:RadPanelBar ID="ParameterPanels" ExpandMode="MultipleExpandedItems" runat="server" Skin="Web20" Width="95%">
            <Items>
                <telerik:RadPanelItem runat="server">
                </telerik:RadPanelItem>
            </Items>
        </telerik:RadPanelBar>
    </div>

In the code behind, I have the following code

                    foreach(ParameterControl aParameterControl in parameterControls)
                    {
                        // Load the parameter controls dynamically as long as we don't
                        // find a static value or data field parameter control
                        if(aParameterControl.ParameterControlID != 2 &&
                           aParameterControl.ParameterControlID != 29)
                        {
                                RadPanelItem panelItem = new RadPanelItem(aParameterControl.ParameterControlDescription);

                                Control c = Page.LoadControl(aParameterControl.ControlPath);

                                panelItem.Controls.Add(c);
                                ParameterPanels.Items.Add(panelItem);
                            }
                        }
                    }

and I end up with the following stacktrace

Server Error in '/' Application.

Object reference not set to an instance of an object.

Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

further info:

Interestingly, if I change my markup to look like this, I don't get the error (I removed the first radPanelItem in the radPanelBar items collection)

<div style="margin-left: 20px;">
<telerik:RadPanelBar ID="ParameterPanels" ExpandMode="MultipleExpandedItems" runat="server" Skin="Web20" Width="95%">
</telerik:RadPanelBar>
</div>

I would have thought that the control wouldn't be sensitive to an empty RadPanelItem but it obviously is. I would suggest that a null check is placed in the source for the next release around if that is the root of the issue.

Telerik.Web.UI.ControlItem.get_Index() +31
   Telerik.Web.UI.RadPanelItem.get_IsFirstVisibleItem() +27
