Hello,

I have a problem with treeview display.

Here's the aspx..

<telerik:RadTreeView ID="radTVFolders" runat="server" AccessKey="T" Skin="Default" EnableEmbeddedSkins="false" CollapseAnimation-Type="Linear" ExpandAnimation-Type="Linear" EnableDragAndDrop="false" ShowLineImages="False" OnClientNodeClicked="ClientNodeClicked" OnClientNodeClicking="ClientNodeClicking">
<CollapseAnimation Type="OutSine" />
</telerik:RadTreeView>

Also, please find attached the screenshot of the weird treeview display. Since the treeview does not show up properly it throws javascript error "this._element is null or not an object" on mouseover of the nodes.

When I see the view source of the page, I see that the div tag is not well formed. It comes up as "<divclass="rtMid">" for the node which breaks.

The issue is random. Can you please suggest?

Thanks in advance

[Solved] DisplayToUtc

I've recently been updating some of my out dated scheduler code to use the newer UI dll's as well as newer custom advanced from templates.

I've noticed the use of this DisplayToUtc method in some area.

I was hoping someone could expand on the little documentation on this method and perhaps comment on where and how it should be used.

I just did a test in the save click method of the advanced form. I chose Aug 25th at 9am as the start date.

>>> apt.get_start()

Date {Thu Aug 25 2011 09:00:00 GMT-0400 (Eastern Daylight Time)}

>>> this._scheduler.displayToUtc(apt.get_start())

Date {Thu Aug 25 2011 09:00:00 GMT-0400 (Eastern Daylight Time)}

So no change in that example.
I'm wondering in what cases should I xpect there to be a change and how this method was intended to be used

regards,
roatin

</Triggers>

<ContentTemplate>

<table class="style1">

<tr>

<td class="style4">

Name:

<td class="style3">

<telerik:RadComboBox ID="rcbName" runat="server" Width="406px" Height="125px"

EmptyMessage="Type media item name" AllowCustomText="true" MarkFirstMatch="true" Sort="Ascending">

</telerik:RadComboBox>

</td>

</tr>

</table>

Any help would be appreciated.

[Solved] Items dissapear and other items get copied after postback

Hi,

Im running in some very strange behavior with the radcombobox (Telerik 2011Q2).
I have 2 dropdownlist and a button. Changing the selecting of the 1st box alters the content in the 2nd box. the button does nothing special, just a postback.

When i change the selection of the first box, the 2nd box gets filled correctly. But when i push the button, the contents of the 2nd box gets alterd, the fist 2 items dissapear and the last 2 get copied and are added to the back.

aspx

<telerik:RadScriptManager ID="RadScriptManager1" runat="server">

</telerik:RadScriptManager>

<telerik:RadComboBox ID="ddlbInstituut" runat="server" AutoPostBack="true" />

<telerik:RadComboBox ID="ddlbAfdeling" runat="server" CheckBoxes="true" Width="300px"

/>

<asp:Button ID="Button1" runat="server" Text="Button" />

vb.net

Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load

If Page.IsPostBack = False Then

vulInstituutDropdown()

End If

End Sub

Sub vulInstituutDropdown()

Dim dsInstituten As DataSet

dsInstituten = SqlHelper.ExecuteDataset(Conn, "SP_GetInstituut")

With ddlbInstituut

.DataSource = dsInstituten

.AutoPostBack = True

.ID = "ddlbInstituut"

.DataTextField = "inst_omschrijving"

.DataValueField = "inst_id"

.DataBind()

End With

vulAfdelingDropdown()

End Sub

Private Sub vulAfdelingDropdown()

Dim dsAfdelingen As DataSet

dsAfdelingen = SqlHelper.ExecuteDataset(Conn, "SP_GetAfdelingen", ddlbInstituut.SelectedValue)

With ddlbAfdeling

.Controls.Clear()

.ID = "ddlbAfdeling"

.DataSource = dsAfdelingen

.DataTextField = "afde_omschrijving"

.DataValueField = "afde_id"

.DataBind()

End With

End Sub

Protected Sub ddlbInstituut_SelectedIndexChanged1(ByVal sender As Object, ByVal e As System.EventArgs) Handles ddlbInstituut.SelectedIndexChanged

vulAfdelingDropdown()

End Sub

The storedprocedures always cough up the correct data.

When useing radListBox, same problem, enabeling or disabeling the checkboxes makes no difference, when useing conventional dropdownlists, no problems whatsoever.

Please help.

[Solved] Feature request; clean up Word/Font stuff

We often have users pasting content from Word or other editors, and often the text contains extraneous codes, extra font tages, span tags wrapped around every block of text, etc. The users often don't even know the extra tags are there (they don't typically use HTML view, and wouldn't understand most of what they would see there anyway). It only becomes noticeable when they ask why the results look 'funny' when viewed. I don't believe this is an uncommon request; I know that we run into it regularly, and had incorporated a solution with a prior HTML editing control that worked well.

What would be nice is to have a couple of button options on the Editor, as follows;

Clean up Font Tags
This would remove any font tags in the content, and remove any nested or redundant markup.

Clean up Word Content
This would remove all extra content added by MS Word, and restore the pasted content to generic HTML.

I know we could sit down and code these, but it would be nice to have them built right in the control.

[Solved] show server side error messages

I would like to show an error message to user
when input validation fails on server side but
keep user on the same input screen with all
values he entered preserved. I know how it is done
using regular approach without Telerik controls. I can inject
javascript which will show DIV styled as a message box
with OK button and on top of other page layers. (kind of lightbox)

I just would like to know if Telerik has built in support for error message display
before I implement a custom error messaging like that.

Thank you.
