Q3 2010 Bug or Change?

Hello,

I installed the Q3 update this morning and I am getting the below error now. After some investigating, I found that it is because my StartDate and EndDate values were set to the same date and time (I am running on converted data so the dates and times were set the same...i.e. 08/25/2005 08:30 AM for both start date and end date). When the scheduler tried to display this on the screen it gave the error. The previous release seemed to handle this scenario ok. It's not a big deal for us since I know the solution and we can set our data up properly. But I wanted to make sure to point it out if this is indeed a new bug with the Q3 release.

Thanks!

ComboBox Postback Through Javascript

Hi I am using Telerik Rad Combo Box, Telerik Rad Grid, Telerik Ajax Loading Panel, and Telerik Ajax Manager on a Page

With the help of Ajax Manager and Ajax Loading Panel I am successfully reloading the grid without reloading the whole page based on the selection Index change of ComboBox(Using AuotPostBack=True property) without any code behind. Now I want to make the AutoPostBack property false because I don't want to postback every time, I will do postback only for particular selection. So I set Autopost back false and I tried to do the postback in Javascript, but now whole page is reloading when ever post back appears. So please help me to postback just the combo box and reload just the grid (not whole page) through javascript

Note : Here I put the combobox in a user control for some additional functionalities and then using that user control on the page with all other controls I mentioned above

Thanks

Https security warning

Hi,

We have development a web app in .Net 4.0, AjaxControlToolKit 3.0.20820.0 and Telerik 2010.3.1215.40. When the app is running under SSL, we get security warining message only from IE8 ( FF, IE7 works fine). I have verified all links are relative and starts with https (I have used http watch). Do I have to setup/update any component?

Please advice.

-Prashanthan

Update 1: I have removed AjaxControlToolKit reference, used RadAjaxPanel instead of update panel and still I am getting the security warning message in IE8. Also, I have tried securitySwitch, customer httpmodule to redirect any request with http to https, and no luck. I have verified http watch, firebug and fiddler 2, and no request are made in http.

Update 2: I have moved the radgrid outside the RadAjaxPanel and now it doesn't show any warning in IE8. Any postback within RadAjaxPanel does show the warning message.

Any help regards this issue is appreciated.

Localized detail table headers lose value when other detail is expanded

I have a grid with DetailTables which are populated using OnDetailTableDataBind. The headers of the detail table are localized server side because the data is different depending upon the parent. When a row is expanded, the details display with the correct header text. The problem is when I expande another row. That's rows header text displays correctly but the first detail table's header text is now empty for each column. I've tried a few ways to set the text but neither hold their values when an additional row is expanded.

                gv.Columns[3].ItemStyle.HorizontalAlign = HorizontalAlign.Right;  
        
            }

Setting the text by getting the LinkButton or by assigning to the HeaderText property of the column work for the row that was just expanded but any other detail tables that were already expanded lose these values.

Any help is greatly appreciated.

Thanks,
Dave
