hi,

i've recently encounter problem while working with radtreeview:

i've radtreeview with datasource (datatable) from database however when i click button i want to change that datasource 

(rebuild radtreeview) and load radtreeview with new nodes and roots; data from database are proper but assigning it to radtreeview 

doesn't work - old "state" radtreeview remains.

is there any way to do this ?

best regards

ksysiek

Value cannot be null.
Parameter name: control

scriptManager.RegisterPostBackControl(btncmd);

Hi everyone.

This is the code

aspx

<

telerik:RadComboBox ID="rcmbPrioridad"

                                    runat="server"

                                    Skin="Mac"

                                    AutoPostBack="true"

                                    EmptyMessage=" -Seleccione prioridad- "

                                    MarkFirstMatch="True"

                                    TabIndex="1"

                                    Width="99%"

                                    ToolTip="Prioridad de pago">

     <Items>

         <telerik:RadComboBoxItem Value="0" Text="" />

         <telerik:RadComboBoxItem Value="1" Text="Normal" />

         <telerik:RadComboBoxItem Value="2" Text="Pago programado" />

         <telerik:RadComboBoxItem Value="3" Text="En espera" />

     </Items>

     <CollapseAnimation Type="OutQuint" Duration="200"></CollapseAnimation>

 </telerik:RadComboBox>

<telerik:RadComboBox ID="rcmbTipoPeriodo"

                                     runat="server"

                                    AutoPostBack="true"

                                    Skin="Mac"

                                    Width="99%"

                                    Height="230px">

    <CollapseAnimation Type="OutQuint" Duration="200" />

</telerik:RadComboBox>

vb
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
    If Not Page.IsPostBack Then

End Sub

Protected

Sub rcmbPrioridad_SelectedIndexChanged(ByVal o As Object, ByVal e As Telerik.Web.UI.RadComboBoxSelectedIndexChangedEventArgs) Handles rcmbPrioridad.SelectedIndexChanged

    do something....

End Sub

Private

Sub pcHabilitaCtrlRegistro(ByVal bolCtrlLlave As System.Boolean

    rcmbTipoPeriodo.Enabled = bolCtrlLlave
End Sub

The problem is when I change te seleccion of  "rcmbPrioridad" control the code does the following
1- Page_Load event    (Its correct)
2- rcmbPrioridad_SelectedIndexChanged    (Its correct)
3- rcmbTipoPeriodo_TextChanged   (Thast the problem)

Why enter to 3 step if any control change text property of rcmbTipoPeriodo

Thank so much.

I am using radeditor’s old version and now i want to upgrade to new one.

I downloaded the trial version and problem I am facing is, when I insert any ‘<span’> tag in radeditor, and try to read  the content of radeditor I am getting <font> tag instead of <span> tag.

For ex.

$find("RadEditor1").set_html('<span> hi </span>');

alert($find("RadEditor1").get_html());

I am getting alert ‘<font>hi</font>’ instead of ‘<span>hi</span>’.
