I'm trying to implement an appointment context menu, unfortunately it's giving me an exception here:

Javascript -

The scheduler's code is as follows:


The I even tried generating the context menu from telerik's plugin GUI.

Thanks in advance for your help.

Hi,

I am opening a rad window from code behind on a button click.   The rad window is used to display the contents of a multi-line text box.  I pass 3 parameters, strErrorId, strFieldName and strFieldValue,  to the window and usually it works fine.  But ,I get the error ' ...is not a valid virtural path' when one of the parameters passed to the window contains the name of an aspx page or is stored with multiple lines.

Does anyone know how I can pass these type of parameters correctly?

Thank you for your help.

For Example:
If the strFieldValue parameter is http://localhost:54807/WebForm6.aspx then I get the error
~/Modules/Central/WBF CTL Large Field Display.aspx?&ErrorId=216ad1a1-d3b8-4ef0-b70d-c4b1b44fa0d8&FieldName=HTTP Reference&FieldValue=http://localhost:54807/WebForm6.aspx' is not a valid virtual path.

If the strFieldValue parameter is Mozilla/4.0 (compatible; MSIE 8.0; Windows NT 6.1; WOW64; Trident/4.0; SLCC2; .NET CLR 2.0.50727; .NET CLR 3.5.30729; .NET CLR 3.0.30729; InfoPath.2; .NET4.0C; .NET4.0E) then I do not get the error.

If the strFieldValue parameter is the following I also get the error.
HTTP_CACHE_CONTROL:no-cache
HTTP_CONNECTION:Keep-Alive
HTTP_CONTENT_LENGTH:524812
HTTP_CONTENT_TYPE:application/x-www-form-urlencoded

Below is the code I am using to open the rad widnow

I have a RadScheduler and RadMenu on the same page and if the web browser height is not tall enought when you open any dropdown menu on the page it open upwards and under the RadMenu control.  I've tried setting the Z-index on the RadMenu and Scheduler but it doesn't seem to help.  How can I make the dropdowns on the adavance edit form always pop up over the remu.  Please see the screen shot of the current problem.

Thanks

I have a custom add/edit appointment form and on it I have an All Day checkbox.

I'd like to use the functionality that appears in the more standard forms in that when the checkbox is checked, the time pickers disappear.

Being naturally lazy, I didn't want to have to write the code myself. Is it possible to tie in to the script that the standard forms use?

Hi,
I am post form data from, say, source.aspx to destination.aspx page. The source.aspx page has some checkboxes which are used in a SQL query in the destination.aspx page. For example,

 if (Request.Form["color_spice"] != null) { WhereClause += " OR ado_products_fabrics.color = 'spice'"; }

The first time the destination page loads the RadListView shows the pagination fine. However, clicking on the RadDataPager under the RadListView causes a postback where the source.aspx page's Form data are lost. I have tried using PreviousPage.FindControl() method but that too does not resolve in the pagination's postback.

So what can I do? I don't want to use Session variables--there are going to be dozens of controls from the source.aspx page passing values to destination.aspx page. Cookies too will be too much to track then?

Below are the code-fragments for the .aspx and the .cs files.

Thanks!

Hi experts
i am using following code and it is not showing me advanced form, if i remove the advanced-form mode attribute than it is working fine.
Could you explain me the concept behind this

We have a requirement to show scheduled tasks for each individual. The tasks will be edited using a different mechanism, not via the scheduler, but we'd like to display them on a scheduler screen.

The data is loading, but the text on the calendar is blank; the attached screenshot shows how it looks, with the tooltip visible but no text on the calendar. here's the definition.


Any idea what's wrong?

I have a RadCombobox in a tooltip, and want the dropdown to be shown when the tooltip is displayed. But setting OpenDropDownOnLoad to true doesn't work...
