Hi,

I've got another question about the scheduler control. The appointments are loaded from a WCF webservice and thus the AppointmentCreated event is not fired serverside. We've used the client-side double click event to attach an event handler to show a radwindow on doubleclicking an appointment. The window is showed as expected, but the default scheduler window is also showed by the scheduler control. If we throw an exception at the end of the 'show popup' JS function the schedulers' popup is killed, but I don't find that to be a correct solution. Is there a way to prevent the default popup from showing?

[Solved] Open Rad Confirm and alert dialogs from server side code

Hi,

I am rolling out a consistent set of alert dialogs and controls across our systems and part of this task is to get rid of old error/informational messages and replace them with something better.

i like the radwindow alert and confirm dialogs and want to embed them in our existing codebase.

What we currently have is a method in our basepage called showAlert..

    
            protected void ShowAlert(string msg) 
        
            { 
        
            var myScript = string.format("alert('{0}');",msg); 
        
            Page.ClientScript.RegisterStartupScript(this.GetType(), "SCR", myScript, true); 
        
            }

This just makes a basic javascript alert popup once the postback has finished and alerts the user.

I want to replace this with the radWindowManager and use the built in alerts.

How can i initiate the alert and confirm dialogs from the server side? there seems to be no examples available.

I tried adding a radwindowManager to my page, then i modified the ShowAlert() method like so....

    
                    protected void ShowAlert(string msg) 
        
                    { 
        
                        string myScript = string.Format("radalert('A string.', 200, 100,'{0}');", msg); 
        
                        Page.ClientScript.RegisterStartupScript(this.GetType(), "SCR", myScript, true); 
        
                    }

but i get the following error...

_5 is undefined

radalert()("A string.", 200, 100, "hello")ScriptRe...=53f5b61a (line 8)

default.aspx()()default.aspx (line 135)

var _6=_5._getStandardPopup("alert",_1);

What am i doing wrong here?

Linked Menus

I have 2 menus on a simple ASPX page. A top menu and a left menu. The left menu is a subset of data from the item I click on in the top menu.

I can get this to work properly, but ONLY on the first item I click on in the top menu. After that, the left menu only displays the initial data even though I rebind the menu with the new data set.

Here is my code:

    
            ASPX: 
        
            <telerik:RadScriptManager ID="RadScriptManager1" runat="server"> 
        
                    </telerik:RadScriptManager>

                        <CollapseAnimation Type="OutQuint" Duration="200"></CollapseAnimation> 
        
                    </telerik:RadMenu>

                    <br /> 
        
                    <br />

                <Item title="Menu 5" description="" /> 
        
            </Items>

I can see when I debug, that the left menu has no data in it and that the correct data is being databound to it, however I always end up with the inital data.

Any thoughts or suggestions would be GREATLY appreciated!

Expanded Parent Node not set to [-]

I have a tree structure with more than 2300 nodes in it. Initially my treeview was set to ExpandMode= ClientSide, but the performance was very slow. Then I changed the ExpandMode= ServerSideCallBack and my page much more responsive but it started having the issue mentioned in:-

http://www.telerik.com/community/forums/aspnet-ajax/treeview/expanded-parent-nodes-not-set-to.aspx

Is there a way to overcome this issue when ExpandMode= ServerSideCallBack?

Thanks

GridBoundColumn - can't click in EditMode for a single column grid

I may have found an issue with RadGrid...?

I have a grid that has a GridEditCommandColumn, one visible editable GridBoundColumn, and some invisible GridBoundColumn data items. The EditMode is InPlace.

If you put the row into edit mode, you can't click on the textbox to edit it. You can tab to it, but you can't click it.

If I add another visible editable column to the grid, the problem goes away.

And I can get around it by manually setting focus to the textbox in ItemDataBound.

--Eve

The grid declaration:

<telerik:RadGrid ID="ConfigGrid" runat="server" AutoGenerateColumns="False"

OnNeedDataSource="ConfigGrid_NeedDataSource"

OnUpdateCommand="ConfigGrid_UpdateCommand"

OnItemDataBound="ConfigGrid_ItemDataBound"

ShowStatusBar="True" AllowPaging="False" AllowSorting="true">

<mastertableview autogeneratecolumns="False" editmode="InPlace" commanditemdisplay="Top"

DataKeyNames="BELawSecCitationDetailID,RowVersion" AllowSorting="true" AllowMultiColumnSorting="true">

<telerik:GridSortExpression FieldName="IsAssociated" SortOrder="Descending" />

<telerik:GridSortExpression FieldName="Citation" SortOrder="Ascending" />

</EditFormSettings>

Javascript error if a span tag is in Node text

Hi,

I'm setting the node text on databind, with some HTML tags in the text. This has been no problem, except recently. If there are one or more <span> tags in the text, I get a javascript error on mouseover:

Message: 'this._element' is null or not an object
Line: 178
Char: 1
Code: 0
URI: http://localhost:1360/ScriptResource.axd?d=DMsgcAGno5aOYK0aJwUvXdDJxcknSyeyRU4cG7Y7I2kuvLi_brGedLWr9i1aLqYyY_ZriuetXXzd7bzZtgAS4w2&t=633798049441157248

If I remove the <span> tags, everything works flawlessly. Is there any way I can fix this without removing my span tags?
