Apply CSS Class not working for images in IE9

If I specify a content area CSS class like this:

img.right-align

{

float: right;

margin: 5px 0 5px 5px;

}

then the ApplyCssClass toolbar will not apply it to the selected image in IE9. It works in Firefox.
In IE9 if I right-click on the image and choose properties, then I can apply the class.
However, Clear Class from the ApplyCssClass toolbar also only works in Firefox, and Clear Class from the properties window doesn't work in Firefox or IE9.

Disable post back when Autogenerated Edit button is clicked

Hi,

We have the following grid. Earlier when we used to click the autogenerated edit button, postback never used to happen. Now after somebody changed something, a postback is firing on edit button click which is not desired. We need to fire the updatecommand when the update button is clicked inside the edit form.

TreeView not rendering when context menu on same page

I have a TreeView control that renders correctly on my page (style gets applied). However, if I add a context menu to the page my style does not get loaded for the TreeView (it renders as bullet points).

Note: My context menu is for a different control on the page, not for the treeview.

I am assuming this has something to do with both controls using the <ul> element, how can I have both controls on the same page without this rendering issue?

<telerik:RadContextMenu ID="cm1" runat="server" >

Drag & drop hints are lost in Telerik's RadControls for ASP.NET AJAX

I have a Telerik tree and drag & drop node move is in action. But then I applied a theme (bought from somewhere) to the overall design of my site, and now, the hint are gone. When you drag a node, some horizontal hint lines appear, so that you can understand that if you release your node (drop it) where it would be dropped.

23:59 shows as 00:00

Hi,

I'm trying to make the max time that an event can be to 23:59. Even though I set:

DayStartTime="00:00:00" DayView-WorkDayStartTime="00:00:00" DayEndTime="23:59:59"

DayView-WorkDayEndTime="23:59:59"

or

DayStartTime="00:00:00" DayView-WorkDayStartTime="00:00:00" DayEndTime="23:59:00"

DayView-WorkDayEndTime="23:59:00"

In AppointmentUpdate when I try to access EndTime (e.ModifiedAppointment.End.TimeOfDay) I get 12:00:00AM when it should be 23:59:59PM.

Is this a bug, or am I doing it wrong?

Thanks,
Daryl

Generic way of displaying error message in master page while using RadAjaxManagerProxy

Hi,

I have a master page whenere my RadAjaxManager is added and in the content pages, I have RadAjaxManagerProxy .
Now I need to display success/failure messages on the content page events like (button clicks , grid update/ combobox changed etc) in a Label in MasterPage.
Right now I am wiring each control which can cause a failure/success message to the RadAjaxManager using the following code:
RadAjaxManager AjaxManager = (RadAjaxManager)this.Master.FindControl("RadAjaxManager1");
        //AjaxManager.AjaxSettings.AddAjaxSetting(RadButton1, Label1);

        Label lblMessage = (Label)this.Master.FindControl("lblMessage");
        AjaxManager.AjaxSettings.AddAjaxSetting(RadButton1, lblMessage);

This code works fine. But my concern is that in future we may add more buttons/grids/combo boxes in the page. Then I need to add the above code for all controls which may not a scalable solution. A new programmer may not know about the need to wire control as above.

So I was wondering if there is a way to do a generic wiring so that any event happening in the content page can update the label in the master page which is a common scenario.
I have a custom base class for all the pages. So a solution in the base class which will work for all the pages and future pages will be really great.
Any thoughts? Any help will be much appreciated. Thanks a lot..
