How can I prevent users from submitting a form twice?

I would like to freeze the whole page, including menus, and add those buttons that should freeze the page in the code behind file (Some buttons on the page should not freeze the page). I have a master page and using client validators on the page.

Status Bar slightly larger than the window width during load

I have run into an issue where the status bar is slightly larger than the window while the page is loading. Once the page has loaded and the resize handle has been rendered, the size is normal. Is this a bug or is there a way to fix this?

Thanks!

Databind to different tables in DataSet

In one of the example pages for the radTreeView, it says you can bind different levels of the treeview to different tables in a dataset using the DataBindings property. Is there an example anywhere of where to do this?

Thanks,

WindowManager change skin on postback

Hi,

I have a windowmanager added to the page on page_load with its Skin property set to a custom skin which is added by Page.Form.Controls.Add(oWindowManager).

On this page I also have a UpdatePanel control with a button inside, when I click this I want to popup an alert (window.radalert) which works, however I want to change the skin of the windowmanager to another custom skin name.

I understand I have to manually set the css sheets, which i've done. But even if I change the .Skin property from server side it doesn't change.

Is there a way to tackle this?

Thanks

Very Odd RadWindow Behaviour

We've just upgraded from Q3 2007 to Q2 2008 to resolve the Firefox skinning issue. It now looks great in Firefox, but has brought a whole load of new issues with it as well, so for now we've reverted back to the old version.

I don't know if this bug is just local to what we've done with RadWindow, but thought I'd share it just in case. It's quite an amusing one, and one of the strangest UI bugs I've seen to date.

Try creating a RadWindow with these properties, show the modal window, wait for about 15 seconds and see what happens...

InitialBehaviours = Behaviours.Pin
Behaviours = Behaviours.None

Our other issues include no longer being able to call back to the main page and the treeview state being changed somehow between postbacks (which .net is not happy about in the slightest).

Edit - although I said it works fine in Firefox, it has actually reverted from our wonderfully crafted skin back to the default one. But hey - at least the corners work now.

OnRequestStart for Ajax Manager and client side events call

Hi,

I have a code which has a RadSplitter and with in the panels i have other controls like tool bar, html table, tree view etc. I have used RADAjaxManager which has the controlID as the RadSplitter and Update ControlID also as RadSplitter meaning when i perform any actions within RADSplitter, the entire controls within RADSplitter will get updated in Ajax. The entire stuff works fine in IE, when i click on the toolbar button, it calls the client side onclick event of the tool bar button and then moves on to OnRequestStart of the AjaxManager where i decide to proceed to server side or return false and don't execute anything further.
The issue now is when i execute the page in Firefox, the OnRequestStart is getting called first and then it moves further to the client side event of the toolbar button. So the page is not behaving the same in IE and Firefox. Any fix for this?

Multiple controls + loading panel

Hi,

I have created a usercontrol which is sometimes used more than once on a particular page. If I only have 1 instance of the control, e.g:

<

uc1:imagelibrary id="Imagelibrary1" runat="server" ControlType="Images" DefaultTab="Page" Category="Facilities" Type="ParkImage" Title="Facility Images" />

Then it works fine. If I have 2 or more, all the subsequent controls use the 1st controls LoadingPanel, instead of it's own. You can see by the code that it spits out:

    
            UpdatedControls : [{ControlID:"ctl01_Imagelibrary2_ajaxPanelDataList",PanelID:"ctl01_Imagelibrary1_LoadingPanelFull"}]},{InitControlID : "ctl01_Imagelibrary2_dlImages",

            UpdatedControls : [{ControlID:"ctl01_Imagelibrary2_ajaxPanelPaging",PanelID:"ctl01_Imagelibrary1_LoadingPanelFull"}]},{InitControlID : "ctl01_Imagelibrary2_pager",

            UpdatedControls : [{ControlID:"ctl01_Imagelibrary2_ajaxPanelDataList",PanelID:"ctl01_Imagelibrary1_LoadingPanelFull"}]},{InitControlID : "ctl01_Imagelibrary2_lnkPage"

As you can see, the reference to ctl01_ImageLibrary1_LoadingPanelFull should actually be ct01_ImageLibrary2_LoadingPanelFull.

Now if I wireup the AjaxSettings dynamically/programmatically, it works fine and will use the relevant loading panel, however when I try the ASP.NET I get the above result.

OnRowDrop GridDragDropEventArgs e.HtmlElement is 'undefined'

I am trying to drag a row from a Grid into a TreeView. After dropping the row, the OnRowDrop event is fired.

If I drop the row on an <img> or <asp:button> the GridDragDropEventArgs e.HtmlElement of OnRowDrop will return with the Id of the control. However when dropping the row on a TreeView node the argument e.HtmlElement is always undefined.

I have refered to this article as a reference. If I set the the destinationHtmlElement using the method args.set_destinationHtmlElement on the client side before the OnRowDrop event is fired, the argument e.HtmlElement is still undefined when OnRowDrop event is fired.

Is there another way to drop a GridRow into a TreeView?
