Problems with Exand HeaderRow - Items not visible

I have a grouped grid where user can select the whole group or just some groupmembers. If the whole group is selected, the groupitems shouldn't be displayed. If only one or more groupmembers are selected, the group should be expanded.

So I used this code (simplified):


SortedList

 

<string, GridGroupHeaderItem> headerItems = new SortedList<string, GridGroupHeaderItem>();
 



protected

void rtl_ItemDataBound(object sender, GridItemEventArgs e)

{

if (e.Item is GridGroupHeaderItem)

{

GridGroupHeaderItem item = (GridGroupHeaderItem)e.Item;

headerItems.Add(groupDataRow["Betriebegruppe"].ToString(), item);

}

else if (e.Item is GridItem)

{

GridItem item = (GridItem)e.Item;

item.Selected = dataBase.checkIsItemSelected(item);

if (item.Selected && !headerItems[dataRow.Betriebegruppe].Expanded)

{

headerItems[dataRow.Betriebegruppe].Expanded = true;

}

Now, if the headerItems[...].Expanded is set to true, the group expands, but all items which are added after this assignment are set to style="display:none" and are only visible if I collapse and expand in client.

How can I fix this behavior?

A demo with Recurrence?

Hi, I have looked quite hard at what you have on line and a working recurrence sample seems to be absent. If I am wrong - wonderful - please point me to it, but otherwise I am trying to just see this work in a dirt simple way. I have this XML

<?xml version="1.0" encoding="utf-8"?>
<Appointments>
<Appointment>
    <ID>3</ID>
    <Subject>testing 123</Subject>
    <Description>testing</Description>
    <Start>2011-04-23T10:30Z</Start>
    <End>2011-04-23T11:30Z</End>
    <RecurrenceRule><![CDATA[DTSTART:20110423T103000Z
DTEND:20110423T113000Z
RRULE:FREQ=WEEKLY;UNTIL=20120424T000000Z;INTERVAL=52;BYDAY=TU
]]></RecurrenceRule>
</Appointment>
</Appointments>

I am attaching to this as follows

Protected Overrides Sub OnInit(ByVal e As EventArgs)
        MyBase.OnInit(e)
        RadScheduler1.Provider = New XmlSchedulerProvider(Server.MapPath("~/App_Data/Appointments.xml"), True)
    End Sub

What I would like to see is anything at all show up in the scheduler. Its not clear from the documentation as to how to make this work. Thanks.

GridRatingColumn AutoPostBackOnFilter ignored if Precision not Item

For Version Q1 2011 released 04/13/2011, changing the RadControlExamples Grid/Examples/GeneralFeatures/GridRatingColumn/DefaultVB.aspx grid which contains a GridRatingColumn to autopostback, it only works if precision=Item or not specified. if half or exact, the autopostbackonfilter is ignored (although double-click causes a postback).

This works fine in the demo if selecting the rating to filter:

</telerik:GridBoundColumn>

<telerik:GridRatingColumn DataField="Rating"

HeaderText="Rating" AutoPostBackOnFilter="true" ShowFilterIcon="true"

CurrentFilterFunction="GreaterThanOrEqualTo"

CurrentFilterValue="0.0" Precision="Item" FilterDelay="2000"

FilterListOptions="AllowAllFilters">

<HeaderStyle Width="250px" />

</telerik:GridRatingColumn>

This does not postback:

<telerik:GridRatingColumn DataField="Rating" HeaderText="Rating" AutoPostBackOnFilter="true" ShowFilterIcon="true"

CurrentFilterFunction="GreaterThanOrEqualTo"

CurrentFilterValue="0.0" Precision="Half" FilterDelay="2000" FilterListOptions="AllowAllFilters">

<HeaderStyle Width="250px" />

</telerik:GridRatingColumn>

Encounter ERROR when creating appointment via advance insert form

Hi Experts,

I am encountering error. Please see attached snap shot of error.
When I create any appointment via advance insert form it shows me error. When I add appointment from basic insert form it does not show me error, but when I edit any appointment it also gives me same error.
I am unable to add/edit any appointment.

I have master page and radAjaxLoadingPanel, radAjaxPanel placed on my aspx page.
It seems to be a scripting error.....or might be a telerik dll issue that is not referencing properly.

Regards,
Mohsin Jawaid

Load items asynchronously

Hello,

I have a UserControl with different fields and a RadComboBox. I want to reduze the time that the user needs to wait (actually the RadComboBox is populated on server-side and it takes a lot of time).

The content of the RadComboBox is not required immediatly; the user needs to fill some fields before. I want to use a WebService or HttpHandler to fill the RadComboBox asynchronously and make it completly "invisible" for the user.

I found some solutions to load the items using a WebService/WCF but the request is sent only when the user try to display the RadComboBox's content (LoadOnDemand)!

Is there a solution to call the WebService automatically after the page load without an interaction of the user?

Thank you for your help.

RAD Menu Control and Inline editing

Hello,
I have a SharePoint Server 2010 site which use the rad menu control. The problem I'm facing is that this controls are disturbing inline editing OOTB fuctionality. Within any custom list, if you group the elemments by any field and inline editing is enabled in the view, when you try to expand the group, items don't get displayed. That's a strange behavior. You can overcome this problem showing groups expanded by default, by this is not what I need.

Thanks in advance.

How to get filter to work with GridDropDownColumn ListTextValue instead of PK/IDs?

Is there a way to make the filter work with text entered for a RadGrid GridDropDownList and respect the lookup values (ie a databound lookup) for ListTextField instead of the numeric ID?

Also, similar question: When a GridDropDownList column is grouped in RadGrid, the ID is displayed in the group header instead of the databound ListTextField value. So it shows xxx: 1830 instead of xxx: Bob Smith ?
