How to get the cursor between two closing tags?

Hi, I have a strange problem that I cannot solve. See this screen cast: http://screencast.com/t/SaskytTTX5V

As you'll notice I end up with two closing tags nested and butted up against each other, like so:

<p>Some <b>text</b></p>

The problem is that our customers get "stuck" in bold mode because there is no way they can get the cursor between the closing bold and closing paragraph tags without manually editing the HTML code. The screen cast was filmed using an up-to-date version of Chrome, but I think we see this problem in other browsers as well.

How can I get the cursor between those two closing tags?

Also, we have this issue when pasting in HTML from a custom toolbar button. How can I programmatically move the cursor between those two closing tags? I've looked at many forum posts about using ranges to move the cursor, but none have helped me get in between the two closing tags.

Thanks in advance!

dynamic RadTreeContextMenu not activating

I have a content page that contains a RadSplitter. On the left of the splitter is a RadPane with a Radtreeview. the treeview definition is below.

<telerik:RadTreeView ID="rtOutline"

runat="server" AccessKey="w" CausesValidation="False"

EnableDragAndDrop="True" EnableDragAndDropBetweenNodes="True"

EnableViewState="True"

CollapseAnimation-Type="None"

ExpandAnimation-Type="None" OnNodeExpand="rtOutline_NodeExpand" >

<ContextMenus>

<telerik:RadTreeViewContextMenu ID="ElementMenu" runat="server" EnableAutoScroll="True">

</telerik:RadTreeViewContextMenu>

</ContextMenus>

<ExpandAnimation Type="None" />

</telerik:RadTreeView>

As you can see I have subscribed to the Node Expand event of the server side. There is a lot of node building code in here so I won't post it all. however a single child node is successfully created (See image nodeDetail.gif). This image shows the Id from the menu

Protected Sub rtOutline_NodeExpand(sender As Object, e As Telerik.Web.UI.RadTreeNodeEventArgs) Handles rtOutline.NodeExpand

Dim newNode As RadTreeNode = NodeControl.LoadNodes(e.Node, rtOutline)

e.Node = newNode

End Sub

The RadTreeContextMenu is also generated. See attachment MenuDetail.gif this image shows the detail of the menu including the fact that it has childitems.

The process is

The node is generated
the node id is passed into a function to generate the RadTreeContextMenu
and the menu is returned.
the menu is added to the RadTreeView
the menu Id is assigned to the contextrmenuid property
the node is then added to its parent.

Dim nodeMenu As RadTreeViewContextMenu = myMenuBuilder.BuildMenu(targetNode)

nodeTreeview.ContextMenus.Add(nodeMenu)

targetNode.ContextMenuId = nodeMenu.ID

the parent is returned to the controlling function and attached to the tree

When I run this the new node shows perfectly but the menu does not. It shows the standard IE Context menu See result.gif.

The code for building the menu is

Public Function BuildMenu(ByVal myNode As RadTreeNode) As RadTreeViewContextMenu

Dim myMenu As New RadTreeViewContextMenu

Dim menuElements As List(Of ElementWrapper) = LoadElements(myNode.Attributes("IID"))

Dim helpItem As New RadMenuItem

Dim iLoopCounter As Int32 = 0

'***** Loading Menu Item

Dim mnuLoading As New RadMenuItem

mnuLoading.Text = "Loading..."

mnuLoading.Enabled = False

myMenu.Items.Add(mnuLoading)

For Each a As ElementWrapper In menuElements

Dim newMenuItem As New RadMenuItem

newMenuItem.Text = a.Text

newMenuItem.EnableImageSprite = a.Enabled

newMenuItem.Attributes.Add("Command", a.Cmd)

newMenuItem.Attributes.Add("CommandArg", a.CmdArg)

newMenuItem.Attributes.Add("IID", myNode.Attributes("IID"))

If a.Cmd = "HELP_MENU" Then

helpItem = newMenuItem

Dim aSplitter = New RadMenuItem

aSplitter.IsSeparator = True

Dim myStyle As New Style

myStyle.Width = Unit.Pixel(125)

aSplitter.ApplyStyle(myStyle)

myMenu.Items.Add(aSplitter)

ElseIf a.Cmd = "HELP_ITEM" Then

helpItem.Items.Add(newMenuItem)

Else

myMenu.Items.Add(newMenuItem)

End If

iLoopCounter = iLoopCounter + 1

Next

Dim newHeight As Int32 = iLoopCounter * 25

If newHeight > 250 Then newHeight = 250

myMenu.AutoScrollMinimumHeight = newHeight

myMenu.ID = "mnu" & myNode.Attributes("IID")

myMenu.EnableViewState = True

myMenu.ClientIDMode = ClientIDMode.Static

Return myMenu

End Function

I have tried this with and without the view state set and the ClientIDMode and still cannot get it to show,

Questions (in order of priority)

Can you please advise why the menu would not activate?
Why would the menu not be maintained if the viewstate is enabled. this happens if I click on the node after it has been generated

Page 2 of 1

Hi,

I use a RadGrid with my own filter implementation. The user can use a textbox to filter the result (only rows containing the keyword will be added to the datasource in the NeedDataSource event). Now I have the strange issue that if I am on page 2 and do a filter and I end up with a row count which is less than the page size (e.g. the page size is 25 and I have only 5 rows), the RadGrid will show "page 2 of 1" and displays no records.
This only occurs if I grouped after a column, Without grouping, everything works fine.

I the DataBound event I can see that CurrentPageIndex is 1 and PageCount is 1, so something went wrong. Setting the CurrentPageIndex to "0" won't work.

I'm using Q3 2011,

"This is an invalid webresource request " error on Telerik grid load

Hi,

We are using Telerik grids in our website built on ASP.Net 4.0. We are getting an internal exception as:

System.Web.HttpException (0x80004005): This is an invalid webresource request.
   at System.Web.Handlers.AssemblyResourceLoader.System.Web.IHttpHandler.ProcessRequest(HttpContext context)
   at System.Web.HttpApplication.CallHandlerExecutionStep.System.Web.HttpApplication.IExecutionStep.Execute()
   at System.Web.HttpApplication.ExecuteStep(IExecutionStep step, Boolean& completedSynchronously)}

This exception is thrown every time any grid loads. Though, this is not affecting grid's working but we want to track at which point this exception is thrown and how much this can affect our website's performace.

Please help us regarding this.

Export Items in ItemTemplate

Trying to export data from a grid to xls/word/pdf but most of the data is in a ItemTemplate since we wanted to display the information in a diffrent format. Is there anyway to get the data from the ItemTempate (All the information is coming from the same datasource) to the export. (VB Example if you can).

WeekView support on a WCF Bound Scheduler with Date Grouping

I have a Scheduler with the appointments and resources bound from a WCF service.

According to this page on the help site I should be able to use WeekView and MonthView as long as I use ResourcePopulationMode="ServerSide".

With this setting in place and the scheduler set to show WeekView by default I get a server error saying "Date grouped WeekView is not supported when using Web Service binding" (ysod.png)

Which of these is correct? Should I be able to use WeekView and MonthView with date grouping or not?

Also, if I set the scheduler to show DayView by default and then click on the WeekView button on the scheduler it renders as attached (halfrender.png) but also gives an error in Visual Studio (vserror.png)

I am using Telerik.Web.UI.dll version 2011.3.1305.40

Thanks

Simon
