How to have Treeview load on demand loading next nodes when scrolling down

Hello,

Browing a database with thousand of elements hierarchicaly related, I would appreciate having radTreeview load on demand working like radCombobox or RadGrid: as I may have thousand nodes on same tree level, I don't want to read them all but need only to paginate with a fixed page size.

Actual version doesn't offers this , is there something todo ?

Thanks CS

[Solved] Prevent RadEditor from closing tags

I've got two RadEditors collecting static content to put above and below some data driven content that will wind up rendering out on the page like

<body>
<< content from RadEditor1 >>
<< data driven content >>
<< content from RadEditor2 >>
</body>

I'd like to allow a <div> or <table><tr><td> to be left open in RadEditor1 to be followed by </div> or </td></tr></table> in RadEditor2 (this would be entered in the HTML view of the editor).

I've tried setting the ContentFilters to None and the RadEditor automatically closed the tags. So RadEditor HTML would start with <table><tr><td> and when I switch to the designer and back to HTML I now see <table><tbody><tr><td></td></tr></tbody></table>.

Is is possible to force RadEditor to not fix the HTML for me?

Thanks for your help!

Editor inside usercontrol - OnClientPasteHtml event doesn't fire

Hello

I've got a user control featuring the RadEditor, and I've been using the OnClientPasteHtml event handler to strip out html pasted into the content pane via Ctl-V. I'm maintaining a clients' code base and they report this was working okay until recently. They're using 2013.2.717.45 of Telerik.Web.UI.

I've found that the unwrapped version of RadEditor fires OnClientPasteHtml just fine. If I create a usercontrol, add an Editor instance with the exact same configuration, and add the usercontrol to the page, the client side event no longer fires.

Issue occurs in IE11, FF, Chrome and Safari.

Help or guidance would be appreciated, thanks very much.

RadEditor not wrapping when using <pre> tag

We intially had textarea being used in our application. When we changed to RadEditor, all our old records did not apply line breaks, since there were no <br> tags. They had new line characters. So I am using <pre> tag inside RadEditor to display them in next line. But now there is an issue while we copy and paste text from an editor. The text wrapping does not occur and we get horizontal scroll. Need help to wrap the text.

[Solved] RadGrid and paging reset

Hello.

Inside an UpdatePanel, I have a "search" button and a RadGrid. The grid is programatically data-bound whenever the search button is clicked. I also have a RadAjaxManager which enables the paging (otherwise, "next" and "back" always return the first set of results). The problem is, if I select say the second page of a set of results, then click "search" to create a different set of results, the grid shows the correct results but the paging is still on page 2, and I'd like it to start on page 1.

I have tried to reset the paging index to 1 on my search button onclick, to no avail. I cannot set it on the databind bit, since that is called whenever a new page is selected.

Any help appreciated.

Custom server side paging

I am trying to implement server side custom paging and using https://demos.telerik.com/aspnet-ajax/grid/examples/functionality/paging/custom-paging/defaultcs.aspx as a reference.

Please refer to your following code

protected void RadGrid1_NeedDataSource(object source, GridNeedDataSourceEventArgs e)

{

MyBusinessObjectCollection MyBusinessObjectCollection1 = new MyBusinessObjectCollection();

int startRowIndex = (ShouldApplySortFilterOrGroup()) ?

0 : RadGrid1.CurrentPageIndex * RadGrid1.PageSize;

int maximumRows = (ShouldApplySortFilterOrGroup()) ?

MyBusinessObjectCollection1.SelectCount() : RadGrid1.PageSize;

RadGrid1.AllowCustomPaging = !ShouldApplySortFilterOrGroup();

RadGrid1.DataSource = MyBusinessObjectCollection1.Select(startRowIndex, maximumRows);

}

If the user uses filtering, say in the example, searching for Unit Price 9, in this case, your ShouldApplySortFilterOrGroup() would return a true. That means maximumRows will be count of entire dataset. So, MyBusinessObjectCollection1.Select(0, 100000); would be very expensive.

I also noticed, that when filtering, items in pages in the bottom right of the grid doesnt display the correct item count.

Do you have another working example of server side paging which allows filtering?

Thank you

Time Zone On Appointment

I am in the process of adding Time Zone functionality into our existing Scheduler which did not include it. I am having an issue when I set a TimeZoneId on the Scheduler and then use the Advanced Form with EnableTimeZonesEditing turned on. The times of the appointment that get stored in UTC reflect the time zone of the Scheduler, not for the appointment. For example, if I set the TimeZoneId of the Scheduler to "Pacific Standard Time" and add an appointment for July 25, from 1:00 PM to 2:00 PM with a timezone of "Eastern Standard Time", I would expect the stored time of the appointment to be 17:00 to 18:00 UTC. However, when I view the appointment in the AppointmentInsert event, the start time is 20:00 UTC and then end time is 21:00 UTC, even though the TimeZoneId of the appointment shows as "Eastern Standard Time".

Am I supposed to do the calculation myself when adding an appointment with a different timezone than the Scheduler, or should this be done automatically? Looking at the code for the Time Zones demo for the Scheduler, I don't see any additional code for this calculation, yet it seems to work as expected.
