[Solved] Grid within the UpdatePanel, I can not export

I'm changing the gridview by RadGrid and am using the export feature (the same site http://demos.telerik.com/aspnet-ajax/grid/examples/generalfeatures/exporting/defaultcs.aspx example, the buttons on the same grid and with all three options checked:
Export only date
Ignore paging (exports all pages)
Open Exported data in new browser window

Except that when I put on my pages, I realized that the export does not work when you have the UpdatePanel.

How do I fix this?

RadMenu MenuItem Css class

Hi
I am using a RadMenu with items created on the client. All menu item selection events are client side.
It appears that the hover Css class is maintained by a menu item when clicked and only removed when another item is clicked.
This is not desirable when a root item has no child items.
In one instance in my application, selecting a root item opens a modal RadWindow. Once the RadWindow is closed, the hover Css class on the selected root item can not be removed. It remains set until the application is rebooted.
Is there a remedy for this issue?
Regards
Harry Kable

Set Edit mode property in ItemDataBound event handler

Hello

I need to set grid rows to edit mode base on there model data. For this purpose I use ItemDataBound event as following

                    Private Sub weldsGrid_ItemDataBound(ByVal sender As Object, ByVal e As Telerik.Web.UI.GridItemEventArgs) Handles weldsGrid.ItemDataBound         
                If (e.Item.ItemType = Telerik.Web.UI.GridItemType.Item OrElse _         
                    e.Item.ItemType = Telerik.Web.UI.GridItemType.AlternatingItem OrElse _         
                    e.Item.ItemType = GridItemType.EditItem) Then         
                     
                  If (e.Item.ItemIndex > -1) Then         
                    Dim row = CType(CType(e.Item.DataItem, DataRowView).Row, MyDataSet.DataSetRow)         
                    e.Item.Edit = row.IsActive()         
                  End If         
                     
                End If         
              End Sub         

And it set up the first time row to edit mode but then if I make grid rebind with another filter in my stored procedure and load other data incorrect row will be editable (on the same place as was item before - it passed to ItemDataBound with EditItem type and code set Item.Edit to false). After that any postback cause viewstate load exception

Failed to load viewstate. The control tree into which viewstate is being loaded must match the control tree that was used to save viewstate during the previous request. For example, when adding controls dynamically, the controls added during a post-back must match the type and position of the controls added during the initial request.

Is it possible somehow to manipulate with row Edit mode from ServerSide using model data?

Thanks in advance

[Solved] can't page or sort

hi, when i try to sort or move page, the whole page is posted back and i get nothing in my grid.
when i refresh the page after that, i see it ok.
How do i prevent the posting back and how do i make it display the contents ok.
this is my grid:

<telerik:RadGrid ID="RadGridMailingList"

Width="97%"

AllowSorting="True" PageSize="15" AllowPaging="True"

runat="server" Culture="he-IL" ShowStatusBar="True" GridLines="Vertical">

<ExportSettings ExportOnlyData="True" FileName="MailingList"

IgnorePaging="True" OpenInNewWindow="True">

</ExportSettings>

<MasterTableView Width="100%" Summary="RadGrid table" Dir="RTL"

NoMasterRecordsText="אין רשומות להצגה." CommandItemDisplay="Top">

<CommandItemSettings ExportToPdfText="יצוא ל PDF"

ShowExportToCsvButton="True" ShowExportToExcelButton="True"

ShowExportToWordButton="True" ExportToCsvText="יצוא ל CSV"

ExportToExcelText="יצוא לאקסל" ExportToWordText="יצוא ל Word"

RefreshText="רענון" ShowAddNewRecordButton="False" ShowRefreshButton="False"></CommandItemSettings>

<PagerStyle PagerTextFormat="Change page: {4}  עמוד <strong>{0}</strong> מתוך <strong>{1}</strong>, פריטים <strong>{2}</strong> עד <strong>{3}</strong> מתוך <strong>{5}</strong>." />

</MasterTableView>

<PagerStyle Mode="NextPrevAndNumeric" PageSizeLabelText="גודל עמוד:"

VerticalAlign="Middle" />

<StatusBarSettings LoadingText="טוען..." ReadyText="מוכן" />

</telerik:RadGrid>

also there is a bug in PageSizeLabelText, seems like the value can't be applied and the original "Page Size:" remains.

Location of Edit series or occurence dialog

Hi there,

Is it possible to use the OnClientRecurrenceActionDialogShowing event to set the location of where the dialog opens on the screen? We have a long vertical list of resources (rooms) on our calendar, and when a recurring appointment is edited the dialog box opens centered vertically on the long scrolling browser window. Often far away from where the user has chosen an appointment, resulting in them having to scroll down to find the dialog to do the edit.

Thanks
Gavin

<script type="text/javascript">
   function OnClientRecurrenceActionDialogShowing(sender, eventArgs)
   {
       eventArgs.set_cancel(true);
       //Edit this instance only:
       //eventArgs.set_editSeries(false);

       //Edit the entire series:
       eventArgs.set_editSeries(true);
   }
</script>

AppointmentUpdate Server event (Drag)

When dragging and dropping an appointment, the AppointmentUpdate Server event has the same value for the event args for the e.Appointment AND e.ModifiedAppointment. When I add the client event OnClientAppointmentMoveEnd, I get the correct modified value on the client side, but the serverside is always wrong.
How can I get the modified Appointment from the AppointmentUpdate Server event after dragging ?

Thanks

2 Menus 2 Different Styles

Hello,

I have 2 rad menus on my page. One for the main site navigation and the other for general content navigation.

The main site navigation has the following properties:

<telerik:RadMenu ID="mainMenu" runat="server" EnableEmbeddedSkins="False">

I have custom images I am using for this menu.

My 2nd menu is just a standard menu with EmbeddedSkins turned on. The problem is with EmbeddedSkins turned on in the 2nd menu, it enables it in the first menu as well.

How can I enable in one and disable in the other without affecting both menus?

thanks

Recurrence issue

I'm having an issue with recurring appointment editing.

If i create a recurring appointment
then edit one of its occurrences to create an exception in the master recurrence rule
then i edit the series to change the time
on the date of the exception, the scheduler shows 2 appointments, one for the exception and one for the recurring series.

this only happens after i edit the series after creating the exception occurrence.
