RadGrid Ajax

help,

Is there a way to have the RadAjaxManager watch a grid and have the loading panel fireup when the user changes filtering option and not have the loading panel fireup when the user clicks a checkbox in the grid?

I have a grid with users displayed in rows and five columns in each row with each one being a checkbox. I don't want the checkbox to cause the loading panel, but I do want the filtering to cause the loading panel. I do need the postback on my check changed event

Foolish mistake

I was just about to make a post about a bug I thought I had come across but I realised it was probably my own mistake, but i thought i'd post here any way so other people dont make the same mistake

If you have a blank page and put a prometheus editor, a required field validator (with an associated control) and a non prometheus rad ajax panel you get some funky JS errors like

Error: 'this._contentHiddenTextarea' is null or not an object
Error: 'addEventListner' is null or not an object

The answer of course is to use a Prometheus ajax panel and it all works nicely :)

RadChart Bar width

i want to assign radchart Bar width in pixel. i am binding chart with dataset.
so that if there is only 1 item(1bar) in the graph then width should not expand to whole width of the chart.
Barwidthpercentage sets bar width with respect to items. but if there is less items then barwidth increases.

thanks

[Solved] Programmatic Recurrence Rule Exception Yields Wrong Time

I have come across an issue in which the exceptions for a given recurrence rule are not being programmatically generated properly. The date portion is correct (that is, the date at which the exception is supposed to occur), but the time is wrong. I'm likely doing something wrong (as RadScheduler can figure out the correct time), but I wasn't able to track down a solution.

The initial recurrence rule (programmatically created from a database record) is this:

DTSTART:20100115T090000Z
DTEND:20100115T170000Z
RRULE:FREQ=WEEKLY;INTERVAL=1;BYDAY=MO,WE,FR

When I go to add an exception for this weekly recurring event on 1/20/2009, RadScheduler gives me this new rule on the OnAppointmentUpdated event:

DTSTART:20100115T090000Z
DTEND:20100115T170000Z
RRULE:FREQ=WEEKLY;INTERVAL=1;BYDAY=MO,WE,FR
EXDATE:20100120T090000Z

Obviously, I trust that RadScheduler is doing the right thing here.

In order to capture exceptions (in this case a delete), I insert a new row into my table with the exception start date 1/20/2009 9:00 a.m., and an end date 1/20/2009 5:00 p.m. (to maintain the parent event duration), with a foreign key to the parent event. When I generate the new recurrence rule for the parent event, I find the exception and attempt to add it to the recurrence rule programmatically using the exception start DateTime (in this case, the one mentioned above in bold)...

a la...

    
            rule.Exceptions.Add(exception.StartDate);

This is the result immediately following the call above:

DTSTART:20100115T090000Z
DTEND:20100115T170000Z
RRULE:FREQ=WEEKLY;INTERVAL=1;BYDAY=MO,WE,FR
EXDATE:20100120T170000Z

They are identical apart from the exception date time. I don't know why the end time for the relation is being used on the exception. I have stepped through my code to verify that the DateTime object being used to generate the exception is indeed correct (and it is). The recurrence rule should have no notion of the exception end time unless it is being inherited from the recurrence start DateTime.

Just in case this is helpful, I am using the ASP.NET Ajax Q2 2009 version of the Telerik controls.

Am I missing something obvious?

Radgrid inside radwindow

Hi everyone,
I am using sitefinity and having a usercontrol named forexample UserControl1.ascx. I created a new page on sitefinity named as page.aspx. I am using UserControl1.ascx inside page.aspx. There is a radwindow calling another page called pageincludingradgrid.aspx inside page.aspx. And my problem is , radgrid page size and paging doesn't work. When radgrid postbacks the radwindow, radgrid disappears. I know that radwindow based on IFrame. So I could not figure out the radwidows behaviour.. I could not rebind the grid to see the related data on correct page index.Any idea please? I need help ..thanks

RadGrid InsertCommand

Hi,

For some reason I can't get a reference to a control in the InsertCommand handler

This works for update:
Private Sub RadGrid1_UpdateCommand(ByVal source As Object, ByVal e As GridCommandEventArgs) Handles RadGrid1.UpdateCommand
Dim editItem As GridDataItem = DirectCast(e.Item, GridDataItem)
End Sub

But this does not:
Protected Sub RadGrid1_InsertCommand(ByVal source As Object, ByVal e As GridCommandEventArgs) Handles RadGrid1.InsertCommand
Dim insertItem As GridDataInsertItem = DirectCast(e.Item, GridDataInsertItem)
End Sub

I allways got this message:
Unable to cast object of type 'Telerik.Web.UI.GridCommandItem' to type 'Telerik.Web.UI.GridDataInsertItem'.

Help?
Thanks Laslo

2. View the page and scroll down
3. Click on a toolbar that opens a dialog
