Upgrading Q1 2008 to latest version

Hi,

I've been searching for an hour with no luck... I really think a link to some upgrade information and procedures would be extremely useful.

I'm wondering what would be the side effects of upgrading my current trial controls Q1 2008 to what ever the lates on is now. Will it just fix the exising bugs? Will the properties change and will things break? To what extent?

Finally, what's the best way to do it?

Thanks.

RadDock and dynamic user controls

Hi, I'm building an application that uses RadDocks and RadTreeView.

I want the user to drag and drop a RadTreeNode (that identifies a user control) onto a RadDockZone. After this dragging, a new user control is istantiated into a dynamic RadDock.

Now this user controls expose a lot of properties that I want to set and I want them to persist on postback.I know I have to instantiate the dynamic controls during Page_Init but if I use the HandleDrop event, I can instantiate it only after the Page_Load.

Now the question is: how can I instantiate the control in the page init?

Thanks a lot,
Marco

[Solved] Problems with spacing docks within a zone

Hello,

So basically im creating a page that has 2 dockzones both with orientation set to hoirzontal. What I would like to do is leave around 20-25 pixels between each dock within the zone, and like it to remain like that alwys, i.e. when a new dock rom another zone is dragged on there, it should also remain 20-25 pixels away from the existing ones.

I tried setting the Left properties of the docks to no avail, I also put a style tag and set margins but somehow this did not give me the desired reults either. Is there an easy way to do this, just a simple css hack. or am i missing something here?

Thanks for your replies!

Best,
M

Drag & Drop labels on row interfering

I am using Drag & Drop (DD) on the radGrid and everything is working fine except for where I DD on a control (this case a label) that's on the row.

Is there a way for the DD event to be fired if I DD on the label on the row, if I DD anywhere on the row where there is no label the event is fired properly.

Thanks

CssFiles vs. ContentAreaCssFile and background color

Hi,

I have gone through the documentation which helps in setting the default background color and fonts in editor.

The article says using ContentAreaCssFile property to assign the css file containing body class to change background color.

I did the same but it doesn't work. If I assign the same file using CssFile.Add method, it sets the background color.
But, this takes away all the classes that were in the 'Apply CSS' dropdown tool. I need them.

I'm using Telerik theme from DLL resource by simply assinging 'telerik' name to skin property, and not customizing it.

Here one tutorial says about using ContentAreaCssFile, and other one says about adding external css file.
http://www.telerik.com/DEMOS/ASPNET/prometheus/Editor/Examples/SettingContentAreaDefaults/DefaultCS.aspx
http://www.telerik.com/help/aspnet-ajax/settingeditorbackgroundandcolor.html

What is the right thing to do?
I tried both of them, none works for me. Only using javascript works. But still leaves me with another problem.
Fonts on entire page that holds editor, are smaller than they should be in firefox. It looks good enough in IE.

Thanks,
Chirag

RadEditor as TestBox

Hi telerik,

(Header should ofcause be 'RadEditor as TextBox', not TestBox)

I would like to use RadEditor as a simple editor for .txt, .js, .htm documents without the text beeing html formated. Like a regular multiline TextBox but with buttons (that dont generate html) like Cut, Coyp, Paste, Undo, Redo and Find & Replace. Like when editor is in 'HTML-mode', but with the above mentioned buttons as the only buttons and active/enabled.

Ofcause one shouldn't be able to choose view-modes, as there is no formating or preview.

Is this possible? Thanks in advance!

Selection out of range on Combo when used with radAjaxPanel

I have searched the forum but have not found a related response to the issue I am reciving.

I have a large collection of address that a user might want to add to an editor so I have created an on demand drop down list, and a button (which when clicked inserts the value into the editor)

This all works but does a full postback so I positioned the combo (both inside and outside) the ajaxPanel along with the button and the editor On clicking the button, the address is added correctly, on a subsequent search I get the Selection out of Range: Parameter Name Value.

    
             <telerik:RadAjaxLoadingPanel ID="RadAjaxLoadingPanel1" Runat="server"   
        
                    height="75px" InitialDelayTime="500" Transparency="25" width="75px">  
        
                    <img alt="Loading..."   
        
                        src='<%= RadAjaxLoadingPanel.GetWebResourceUrl(Page, "Telerik.Web.UI.Skins.Default.Ajax.loading.gif") %>'

                    </telerik:RadEditor> 
        
                </telerik:RadAjaxPanel>

Code behind:

    
              Protected Sub rcmbGlobalAddress_ItemsRequested(ByVal o As Object, ByVal e As Telerik.Web.UI.RadComboBoxItemsRequestedEventArgs) Handles rcmbGlobalAddress.ItemsRequested  
        
                    If e.Text = String.Empty Then Exit Sub 
        
                    Dim dl As New Datalogic  
        
                    dtGlobalAddress = dl.getGlobalAddress(e.Text)  
        
                    With rcmbGlobalAddress  
        
                        .DataSource = dtGlobalAddress  
        
                        .DataValueField = dtGlobalAddress.Columns(1).ColumnName  
        
                        .DataTextField = dtGlobalAddress.Columns(0).ColumnName  
        
                        .DataBind()  
        
                    End With

Persisting values in hierarchy when inserting

Hi.

I have a table with a subtable.

The subtable has these fields from main table -
                    <ParentTableRelation>
                        <telerik:GridRelationFields DetailKeyField="SongID" MasterKeyField="SongID" />
                    </ParentTableRelation>

These work great for just showing a list but when I try to Add a new item then SongID becomes nothin but I want it to be the same value as when I see the list.
How can I accomplish that? I need that SongID for my datasource and I want it to be populated even when I do "add a new entry". It just should equal to the main tables SongID.

Thanks
