I have a scheduler set up with an object data source.  I don't seem to have any problems binding the scheduler or making inserts or updates.  The problem comes when I try to delete the first occurrence in a series.  I get a bit of a cryptic error (below).  If I delete the whole series or any of the other occurrences beside the first one, it works.

I also noticed when I look at the list of recurrences, the first item has a little red line between the Yen and Yang refresh icon.  I also notice I do not have a value in the DataRecurrenceParentKeyField that I set - I've tried it both as a varchar and an int.

<-- Error -->
Cannot locate the parent of appointment with ID = '1'. Ensure that the parent appointment with ID = '' exists and is loaded.

I upgraded my DevCraft 2012 Q2 SP2 installation to Q3 today and and VS 2012 is crashing after opening a solution.  I have the following components installed:

• RadControls for WinForms
• RadControls for ASP.NET AJAX
• RadControls for WPF
• RadControls for Silverlight
• KendoUI for ASP.NET MVC
• MVC UI Extensions
• Reporting
• JustTrace
• OpenAccess
• JustMock

After installing, I started VS 2012 and took a very long time (perhaps 20 minutes) to get to a responsive state.  I watched it in Task Manager and it looks like one core was pegged at 100% during this time and RAM consumed grew to over 500MB.

VS did come back eventually and I loaded a solution.  Everything looked for a few seconds and then visual studio crashed.  I tried rebooting and restarting VS but it crashes every time I try to load a solution.  I went into the Windows EventLog and found this error:

I then restarted VS and instead of loading a solution, I tried running TELERIK\VS Extensions Options...  This also failed with a dialog complaining about a missing resource (see the attached image).

I also installed the update on a Windows 7 64-bit machine with both VS 2010 and 2012 installed.  VS 2010 did not have the excessively long startup time but it also crashed when I tried loading a solution.  VS 2012 seems to be stuck loading a solution right now.

Looks like something is wrong with Kendo.  I'm going to try uninstalling it.

While uninstalling all of the Kendo components on my Windows 8/VS2012 machine, I went over to the Windows 7 machine, launched VS 2012 and opened the Telerik\VS Extensions Options...  I didn't get an error message this time but the dialog is messed up.  See the attached image.

Update: After uninstalling all of the Kendo components on the Windows 8/VS 2012 machine, VS2012 was able to load a solution and work normally.  On the Windows 7/VS2010 machine, I'm now seeing VS2010 crash whild loading a solition.

I have a grid which has only one column. it contain image and a text. When i try to drag by clicking on image it won't start dragging operation but i do the same thing with text it start dragging.

Is it a problem with z-index, could you provide proper solution on that ?

It must be very simple but I can't work it out
I've got a grid

(myliteral is filled on temDataBound event.)
I bind the grid on code behind needdatasource event. It works fine.
If I click the GridButton to delete, raising RadGrid1_DeleteCommand event, it performs the delete function. It works fine


Now I just need to add Ajax to this.
so

It is not working. The RadGrid1_DeleteCommand event is performed, but it does not refresh the grid

Could you help me please?

I've been searching your forums and reading documentation for several days now but have been unable to figure out how to access an updated item in my RadGrid.  

Basically, I have a RadGrid with a Client Event where OnCommand is set to "RaiseCommand".

In my JavaScript RaiseCommand function, I am able to determine the command that was raised.  When the command raised is "Update" I am calling ValidateInput function, passing along the sender and eventArgs that was passed to the RaiseCommand function.

Inside ValidateInput, I need to access updated values and do some edits to ensure the new values meet specific requirements.  However I have been unable to figure out how to access the new values.

So I thought I'd try accessing the new values in my codebehind.  I thought that if I could figure out how to do it there, I could use the same method in my javascript.  I created subroutines that handle EditCommand, and UpdateCommand.

Inside my subroutine for EditCommand, I have been able to find and display in a message box, the values in the row where Edit was clicked.

When I execute my web page, after clicking Edit on a row in my RadGrid, I then modify the contents of one of the four fields.  I then click on Update and my subroutine for UpdateCommand is invoked.  Inside this subroutine, I have been able to succesfully find and display the SavedOldValues.  However, I am unable to find the new value that I entered into one of the fields. 

Here's some of my code:

After I click on Update, my UpdateCommand handler fires, and I see message boxes containing the four saved old values.  But the following messages boxes (2 sets of 8) all display &nbsp.

I know there must something fundamental that I'm missing, but for the life of me, I've been unable to figure it out.

Please tell me how I can access the updated values in my codebehind, and then also in javascript.

Thanks!

I'm searching for hours now but nothing I found worked.
I tried out instructions telerik gave and also other approaches.

The page works fine on the first load, but when i push the save button there comes the
error und nothing works.

THANKS FOR HELP!

Sincerely, Skim

Is there a way to export the scheduler into a landscape mode so it fits the entire PDF width? I tried setting the PDF PageHeight and PageWidth to be in landscape, but it ended up only filling half the page width. If I'm missing something, please let me know.

Here is a link to a screenshot of what I got.

Hello,

I'm working with the asp.net RadChart, trying to more finely tune the displayed labels associated with a chart.

Specifically, I'd like to start the axis labels and ticks at a point not at the start of the data, or at 0. In the attached files, I have my current chart's axis (with RadChart) where the labels start at the minValue and end with the maxValue of the Axis.

Target.png represents what I'd like to see in the chart, with the label starting at a pre-defined point in the data. In this case, I'd like to start my labeling at July 1, 2010 instead of April 28, 2010 in the dataset.

Is there an easy way to do this?


Thanks,
Alex Bucevicius

I need to change the maxlength clientside in a RadTextBox depending on a selection in a combobox.  I tried this:

 

var txt = $find("<%= txtValue.ClientID %>");

 

 

var item = eventArgs.get_item();

 

 

var value = item.get_value();

 

 

switch(value)

 

{

 

case "CUST_NU":

 

txt.MaxLength = 8;

 

break;

 

 

case "NAME":

 

txt.MaxLength = 30;

 

break;

 

 

case "CIC":

 

txt.MaxLength = 4;

 

break;

 

 

case "INVOICE_NU":

 

txt.MaxLength = 10;

 

break;

 

}

Then checked for the maxlength via alert(txt.MaxLength) and it shows the new maxlength value but the textbox still doesn't change to the new length.

onclientRequestSuccess does not seem to have the updated firstDayStart().  I thought I had figured it out, but its not working:

As I navigate in the calendar, changing months, it does not reflect the right day - what am I doing wrong?
