I am using NodeTemplates in my RadTreeView and have set EnableDragAndDrop and EnableDragAndDropBetweenNodes to true, however, the lines used to indicate the dropzone between two nodes is not showing up.

Any tips or insight on on how I should go about debugging that?

Thanks,
Neil

[Solved] Client side removeHandler error

Hello,

I have own composite control inherited from RadWebControl. It contains RadTextBox control where I need handle keyup client event.
I have implemented client class for it and I attached event in initialize function. In dispose function I'm removing this event handler but it causes javascript error:

Line: 6

Error: '_events' is null or not an object

Here is the script:

nData.KnowledgeManagement.Web.UI.Searcher.prototype =

{

initialize: function () {

nData.KnowledgeManagement.Web.UI.Searcher.callBaseMethod(this, 'initialize');

// SearchTextBox

this._searchTextBox = $find(this.get_id() + '_searchTextBox');

this._keyUpDelegate = Function.createDelegate(this, this._keyUp);

$addHandler(this._searchTextBox._textBoxElement, "keyup", this._keyUpDelegate);

// XmlHttpPanel

this._xmlHttpPanel = $find(this.get_id() + '_xmlHttpPanel');

this._xmlHttpPanel._searcher = this;

this._xmlHttpPanel.add_responseEnding(this._xmlHttpPanelResponseEnding);

this._xmlHttpPanel.add_responseError(this._clientResponseError);

},

dispose: function () {

nData.KnowledgeManagement.Web.UI.Searcher.callBaseMethod(this, 'dispose');

if (this._keyUpDelegate) {

$removeHandler(this._searchTextBox._textBoxElement, "keyup", this._keyUpDelegate);

this._keyUpDelegate = null;

}

this._xmlHttpPanel.remove_responseEnding(this._xmlHttpPanelResponseEnding);

this._xmlHttpPanel.remove_responseError(this._clientResponseError);

},

_keyUp: function () {

this._search(this._searchTextBox._textBoxElement.value);

},

...

}

Cound you tell me what I have wrong?
Thanks
Jiri

Collapse treeview nodes except active node

Hi in my application i have a treeview control ...
In the pageload i have initialized to collapse all the nodes
The problem is when all the nodes get expanded i am unable to accomodate the list on the page and it gets scrolled...
I need to keep the active selected node displayed with all the other parent nodes collapsed and if i select the other node the previous active node should get collapsed, so that only one node will be active and the rest will be in collapsed state. I hope you got my scenario and will provide a solution for it.

Radeditor Lite on WSS cursur jumps to start of text

We have a problem with the telerik radeditor on WSS v3. We are using the lite editor: 4.5.6

When clicking bold, italic, underline, justify, indent etc. tool buttons in the middle or at the end of some text the cursor jumps to the start of the text(box). When you select some text first the buttons work fine. Also when inserting a table somewhere in the middle of a text it always inserts the table at the start of the text.
Shortcuts like CTRL+B work fine when typing. Toolbuttons like Imagemanager or bullets and numbering work fine as well.

Any help would be much appreciated!

ReorderTabsOnSelect has no effect?

Hi

I am adding tabs to a radtabstrip dynamically and the tabs automatically break over multiple rows when they exceed the width of the tabstrip, which is nice. However when I select a tab in the top row it doesn't reorder - which is not so nice. Similar to this question. I have ReorderTabsOnSelect = true, is there something else I have to set?

Markup:

<telerik:RadTabStrip ID="RadTabStrip1" runat="server"

MultiPageID="RadMultiPage1"

SelectedIndex="0"

Skin="Vista"

ReorderTabsOnSelect="true"

Width="550px">

</telerik:RadTabStrip>

<telerik:RadMultiPage ID="RadMultiPage1" runat="server"

SelectedIndex="0"

BorderStyle="Solid" BorderColor="Gray" BorderWidth="1px"

OnPageViewCreated="RadMultiPage1_PageViewCreated">

</telerik:RadMultiPage>

Source Code:

protected void Page_Load(object sender, EventArgs e)

{

if (Page.IsPostBack == false)

{

//get details of tabs

List<DummyObject> lstDummys = GetTabsFromDataBase(Request.QueryString["Tabs"]);

//loop through and add to page

foreach (DummyObject obj in lstDummys)

{

//add tab

RadTabStrip1.Tabs.Add(new Telerik.Web.UI.RadTab(obj._displayName));

//add pageview

RadPageView pageView = new RadPageView();

pageView.ID = obj._name;

RadMultiPage1.PageViews.Add(pageView);

}

Problem with RadList view and Embedded Grid

I am using the Telerik.Web.UI version 2010.3.1317.40
Visual Studio 2010 premium. .NET 4.0

I have a simple grid, embedded in a simple List View.

The data source for the list view is a Class Object.

When I get to the point that I am trying to get the list views key data value of customer number, it fails to set the parameter.

rg_Contacts.DataSource = mcAddressBooks[intID].AddressBookContacts;

}

The error occurs in the Need Data source of the grid. When I try to set the parentiem, it is set to a value of null, or nothing.
I wind up with an error at the if(parentItem.DataItem == null) section of the code telling me that parentiem is null.

So, the code works for everything but this part, if I had code the intID to 0, and simply set the rg_Contacts.DataSource to mcAddressBooks[0].AddressBookContacts I get it to display, but simply with the 0 index of the class.

I would appreciate any help.

when I try to access th edit form I receive this "Specified cast is not valid" error. Some of the values int he database are Null. I don't know if that has anything to do with it. Please advise.

DataList - ItemDatabound and TooltipManager

I've the following DataList:

<asp:DataList ID="dataListPhoto" runat="server" RepeatColumns="7" RepeatDirection="Horizontal" OnItemDataBound="dataListPhoto_ItemDataBound">

<ItemTemplate>

<asp:Image ID="imgButton" runat="server" ImageUrl='<%# Eval("ImageUrl") %>' Width="32"

Height="32" userName='<%# Eval("User") %>' />

</ItemTemplate>

</asp:DataList>

And want to show a tooltip on each Image (imgButton):

<telerik:RadToolTipManager ID="ttm" Height="200px" Width="350px" HideEvent="LeaveTargetAndToolTip"

RelativeTo="Element" Position="TopCenter" runat="server" Skin="Telerik" EnableShadow="true"

Animation="Fade" ShowDelay="1000">

<WebServiceSettings Method="GetHoveringText" Path="LinkHoveringAuthor.asmx" />

</telerik:RadToolTipManager>

In my code-behind I try to add each Images to RadToolTipManager's TargetCollections:

protected void dataListPhoto_ItemDataBound(object sender, DataListItemEventArgs e)

{

Image c = (Image) e.Item.FindControl("imgButton");

string value = c.Attributes["userName"];

ttm.TargetControls.Add(c.UniqueID, value, false);

}

But the Tooltip is only displayed for the first Image....

2nd question: in my LinkHoveringAuthor.GetHoveringText method I try retrieve the userName:

var contextDictionary = (IDictionary<string, object>)context;

if (contextDictionary["Value"] != null)

{

string name = contextDictionary["Value"

].ToString();

...

It works, but backslashes are omitted... :-|
For example, here:

ttm.TargetControls.Add(c.UniqueID, value, false);

if value="dom\user", in the webmethod, the "name" variable equals to "domuser"...

[Solved] All Day Appointment

In this forum thread we're told that an appointment is 'All day' if the appointment starts at 12AM one day and ends at 12AM the next.

If I go to the Scheduler First Look demo and add an appointment in the all day section, the appointment is created with its start and end at 12AM on the SAME day. But if I edit one of the existing all day appointments, it is set up to start and end at 12AM on consecutive days.

What's right?
