dynamically select child nodes in Load-on-demand treeview

I have a treeview that is set to load on demand.

When the user clicks a node, the page is reloaded with updated info and the treeview is reset back to showing just the parent node.

I need to have it auto-expand back to the previously selected node.

I've tried the FindbyValue method but since the trees not populated, there's no value to be found.

I've tried to navigate thru expanding as I go (I have the path to the end node saved) but I can't force the treeview to expand to populate the child.

Anyway to do this???

thanks.

Scheduler auto fill Date Subject

I have a rad scheduler that I am using to display appointments. However when my user double clicks to add an appointment - i want to auto fill it with some information - is there an event such as "OnAppointmentInsertClicked" or something that will give me access to the subject field that will let me populate the value. So for instance when they double click on a time range I want the little popup to populate with values of the Customer Name. Is this possible?

[Solved] Events on the tree stops working after folder rename/move/delete/..

When the file explorer is loaded I add handlers to intercept context menu handling for the tree view part (I enable/disable menu options). This is hooked up like this

In a user control:

<telerik:RadFileExplorer ... OnClientLoad="EXPLORER.attachHandlers" …

the javascript:

var EXPLORER = {

attachHandlers: function (explorer, args) {

var tree = explorer.get_tree();

tree.add_contextMenuItemClicking(EXPLORER.treeContextMenuClicking);

tree.add_contextMenuShowing(EXPLORER.treeContextMenuShowing);

},

The functions treeContextMenuShowing and is now run every time I right click a folder in the tree and treeContextMenuClicking is run when I click a menu context menu item.

However, those functions isn't called on user interaction anymore after I've done an "updating command", like renamed a folder or created a new folder via the context menu in the tree view. The events stops firing for all the folder nodes in the tree, not only the one(s) I've updated.

I also has showing and click events hooked up for the grid context menu, and they keep working after I do updates to the items in the grid. So the problem is local to the tree.

What do I do to fix this?

Thank you,

Best regards,

RadListBox Client update

Hello everyone,
I am currently using the latest version of the telerik library.
The problem is that I have a RadListBox and I add items to it using the client side API.
It is not working properly as it is not refreshing the UI. But it is adding the items on the background, I know this because when I get the items the added one is in the list.
I have seen old posts about this and says to update to the latest to fix it, but that is not my case :S

Thanks in advance,

Sergio Martinez

Here is the code I'm using:

varPreferencesScheduleList.trackChanges();// this is my list

var item = new Telerik.Web.UI.RadListBoxItem();

item.set_text(newText);

varPreferencesScheduleList.get_items().add(item);

varPreferencesScheduleList.commitChanges();

Radgrid export exception

Hi,

we have a radgrid with paging enabled, advanced databinding using the NeedDataSource event and filtering enabled on a column.

When we call MasterTableView.ExportToExcel() we're getting the following error :
[NullReferenceException: Object reference not set to an instance of an object.]
   Telerik.Web.UI.RadAjaxControl.OnPagePreRenderComplete(Object sender, EventArgs e) +83
   System.EventHandler.Invoke(Object sender, EventArgs e) +0
   System.Web.UI.Page.OnPreRenderComplete(EventArgs e) +8699938
   System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint) +1029

The ExportSettings.IgnorePaging is set to true. When i change that to false the export does work.
I've read a thread on this forum and the answer to this problem was to use advanced-binding but we're already using that.
We're using Telerik.web.dll 2010.1.519.35

Master Pages + RadGrid on Content + RadAjaxManager/RadAjaxPanel/GridAjax + EXport with Default Command Items

hi,

I have a similar scenario like this example ExportFromContentPageWithAjaxEnabled.zip at http://www.telerik.com/community/code-library/aspnet-ajax/general/export-radgrid-content-to-excel-word-csv-pdf-with-ajax-enabled.aspx

but instead of the asp buttons at Grid's CommandBar, i want to use the default image buttons that RadGrid Generate when i use:

<CommandItemSettings ShowAddNewRecordButton="True" ShowExportToCsvButton="True"

ShowExportToExcelButton="True" ShowExportToPdfButton="True"

ShowExportToWordButton="True" />

How i can turn off the ajax for this one at ajax manager?

Best

Fixed elements in a RadPageView

Hi everybody,

I have a page which contains a TabStrip.

The tabs are added dynamically and the pageViews related to the tabs in the event "OnPageViewCreated".

In the pageview of the second tab, I have added 2 usercontrols.
The first usercontrol contains buttons, the second contains a radgrid.
A scroll is automatically added in the Pane for the two usercontrols.

How can I force the first usercontrol to be fixed and the other control to be scrollable?

Thanks for help.

Adding Javascript to RadEditor (MOSS)

In MOSS 2007 I have been adding this:

<a href="JavaScript: GeneralPopup('/SiteCollectionDocuments/HTML/OurPromise/hw_comm.html')">[more]</a>

but when i save, I get this:

<a>[more]</a>

The javascript is supposed to open the link in a custom popup page. How can i get this to work, or are there any alternative ways to get the same result?

I saw this post : http://www.telerik.com/community/forums/sharepoint-2007/full-featured-editor/javascript-in-moss-radeditor.aspx

But the post is way too long and confusing.

[Solved] Preupload Validation

Is it possible to do a preupload validation that requires server-side code?

For example, I want to make sure that a variable is in session before the upload continues. We have users that go thru our upload process, get to the end (which removes all session variables), then they click Back on their browser and try to do another upload. Doing so causes a NullReferenceException.

I'd like to check to see if the session variable exists. If it does, allow the upload to continue. If not, forward them to a new page telling them their session has expired.

Any ideas would be greatly appreciated.

Thanks,
Kyle
