Hello

In this post : http://www.telerik.com/community/forums/aspnet-ajax/treeview/how-to-handle-node-templates-with-load-on-demand.aspx 
i've asked support about how to put togheter load on demand and treeview nodes templates, and the following post has given me hints on how to add gridviews into node templates at runtimes :
http://www.telerik.com/community/forums/aspnet-ajax/treeview/adding-the-radgrid-in-the-nodetemplate-dynamically.aspx. 
Now i've got a tree with the following structure :
year 1
    |_ first quarter 
            |_ department (uses load on demand , server side)
                |_code (uses load on demand , server side)
                    |_template Node : contains an asp.net userControl with a radgrid
    |_ second quarter ...
year 2 ...

All nodes are added programmatically, and the department and code subnodes load their children on demand. Now i need the template node to contains some richer controls to display more than a string , so i've chosen a radgrid.

The radgrid rows should contain also a link button to allow the user to edit the selected record (not inline but redirecting to an appropriate page ).
I've put the grid into a usercontrol and bound it to an objectdatasource, hoping it avoided me to define all the grid properties programmatically, but i can't achieve it , instead if i set the datasource programmaticaly to one of my businness object (which returns a datatable ) it gets instantiated, but i haven't sorting, paging etc.
the second problem happens when i open any of the load on demand nodes : if i had preaviuosly opened another load on demand node , its template node (the grid) gets resetted to an empty node.

Below i've added the code of the page that uses the custom control with grid and the custom control itsself :

1. load on demand expand method


2. custom control node template html



3. custom control template node code behind:



thank you in advance for your support
 
 

Hi Telerik,

    I am having 2 raddatepickers. When I am done with setting the date of the first date picker, the second datepicker must display a date 14 days lesser than the selected date of raddatepicker1. Also, I must be able to edit the RaddatePicker2

    I would like to do this in javascript.

    Thanks for your help.

DataNavigateUrlField="AdminValue" DataSourceID="sdsMenuBuilder"

 

 

 

DataTextField="MenuText" DataValueField="Value" DataFieldID="MenuID" Width="650px"

 

 

 

onprerender="FarsiMenu_PreRender"

 

 

 

style="position:absolute;right:40px;" EnableOverlay="False" AutoScrollMinimumHeight="100" EnableAutoScroll="True">

 

 

 

<DefaultGroupSettings Height="200px" RepeatColumns="1" />

 

 

 

</telerik:RadMenu>

 

When my submenu items height is less thatn 200px, the submenu window is 200px with some empty space.
how can i solbe this problem?
i want when my items heght is less than 200px, the submenu window height be fit to these items.

Hi,

In case, we use the Empty value option, RadChart has supported for Area, Bar, Pie, Buble, Point, Line, SpLine, StackedArea, StackedArea100 chart-type, except for StackedBar and StackedBar100. It's work-as-design of RadChart, isn't it?

Thanks / Phong Dang.

Hi,

We are using Teleric Rad Editor for contnet areas in SHarePoint 2007.
 
While editing Rad Editpr HTML content, if the HTML markup is not properly formed, the editor doesnt give any messages for malformed HTML markup.
 
We are planning to use a custom button there to validate the HTML and specify the errors if any. This button internally will call a web service or use some tool on the server, pass the HTML content to it and shows the errors/messages if any returned from the service/tool.

Is there any add-on or something Telerik provides for Rad Editor for HTML markup validation?

If not, can you please suggest us some tool/web service which we can use with Rad Editor? For some security reasons we do not want to use validator.w3c.org web service. Please suggest us some other web service or tool which suites rad editor more. Also it would be great help if you can tell us what steps we can follow to achieve this customization.

Regards,
Mahavir

 

When I drag and drop a selected row from ASP.NET Ajax (Telerik.web.ui) Radgrid (inside a usercontrol) to a RadTreeview node (inside a usercontrol),

I am able to capture the Datakeyitem of the Radgrid on the RowDrop serverside event of the Radgrid, like

   Private Sub grdEquipments_RowDrop(ByVal sender As Object, ByVal e As Telerik.Web.UI.GridDragDropEventArgs) Handles grdEquipments.RowDrop

        Dim dataItem As GridDataItem = e.DraggedItems(0)

        Dim s As String = dataItem.OwnerTableView().Items(dataItem.ItemIndex).GetDataKeyValue("ID")

    End Sub

But I am not able to get the refrence to the Treeview Node  on which the Item is being dropped.
Do you have any sample projects where you have this functinality.

 please note that these two controls are in separate usercontrols.

 

Thanks

is there any way to have treeview node contain multiple line of text?

I am getting the following cast error,
Cannot cast 'RadPanelBar1.FindItemByValue("QuickSearch").FindControl("txtFirstName")' (which has an actual type of 'Telerik.Web.UI.RadTextBox') to 'System.Web.UI.WebControls.TextBox'

Can anybody tell me what I'm missing.

Greetings,
A while ago I quickly threw together a quick tool to manage our admin users and provide our support staff with the ability to reset users passwords.  It uses a RadGrid, bound to a collection of objects, and there is a GridTemplateColumn that holds an EditItemTemplate that has a textbox to collect the new password.  It used to work, and when we found the textbox in the ItemUpdated event handler, the textbox.text would be new password, and life would be good.  No longer though, now the text is always empty.  We recently updated our telerik controls to 2011.1.413.40, although this could have stopped working before then (it's a rarely used function apparently).  Below is the RadGrid definition and ItemUpdated Event handler.  If anyone has any ideas, that would rock.



Thank you in advance if you have any ideas on this,
Francis
