Ajaxified control fails when using ListView ItemTemplate
Hi all,
I have a problem with a scenario I didn't find in all your demo, kb, and stuff.
I made a user control who work using radajaxmanagerproxy: it's a quite simple form for editing data, some textbox and a couple of combobox, with save and cancel button. If I use this control in an .aspx page, declaring a radajaxmanager, everything works fine.
But, if a create a page with a datalist, and declare the usercontrol inside the item template of the datalist, the ajax stuff don't work so well: the first time I try to use it, it's simply not ajaxified. From the second time on, the ajax stuff works.
I'll put the code of the page and the usercontrol: there are both cases (direct usercontrol declaration and datalist itemtemplate) on the same page. The user control is decalred directly for creating new item, and inside the datalist itemtemplate for editing.

Moreover ther are some minor issues too.
If you try to use the "create new item" instance of the user control, you'll see that the ajax behaviour works fine but the rest of the page's layout is somehow... shaked for some moments. And this happen just the first time a postback occurs.

Not included in the sample attached, I have some problem also trying to put some ajax behaviour also on the .aspx page: if I declare in the radajaxmanager an ajaxsetting involving the single usercontrol instance to update the datalist panel (view following code snippet)
<telerik:RadAjaxManager ID="RadAjaxManager1" runat="server">  
    <AjaxSettings> 
        <telerik:AjaxSetting AjaxControlID="cpi1">  
            <UpdatedControls> 
                <telerik:AjaxUpdatedControl ControlID="cpi1" LoadingPanelID="lp2" /> 
                <telerik:AjaxUpdatedControl ControlID="editPanel" LoadingPanelID="lp2" /> 
            </UpdatedControls> 
        </telerik:AjaxSetting> 
    </AjaxSettings> 
</telerik:RadAjaxManager> 
<telerik:RadAjaxLoadingPanel ID="lp2" runat=server Skin="Sunset">  
</telerik:RadAjaxLoadingPanel> 
 it simply disable ajax everywhere... and I have nomore ajax behaviour avalable.

Need some help please

Radeditor dnn
Hi

I would like to configure my radeditor manager dialogs in dotnetnuke, so the user can upload files, but not rename, move and delete files.

I user my own provider, but when i set the upload path it also enables the rename, can i prevent this ?

A suggestion for development, make a config.xml to handle the dialogs, like on the editor. That would make more flexible.

Thanks for an awesome product :-)

contains problem
Hi,.

I am about to update an application to use the Radlistbox, where I currently use the ASP.NET Listbox.
I have 2 listboxes, where the 1st contains values, that can be transferred to the 2nd.
- BUT the 2nd has already some preselected, and if the values are in the 2nd listbox, they should NOT be in the 1st Listbox.

VERY simple, and no problem when I use the classic listboxes.
But how is this done in Radlistboxes?

This is quite simple, but I couldn't find the answer in this forum.

See my example script:

HTML:
    <form id="form1" runat="server"> 
     
     
    <div> 
        <telerik:RadScriptManager ID="RadScriptManager1" Runat="server"> 
        </telerik:RadScriptManager> 
        hello</div> 
     
     
    <div class="radtxt"> 
        <div style="float: left;"> 
            <div> 
                All Websites:</div> 
            <telerik:RadListBox ID="listWebsites" runat="server" Width="180px"  
                Height="200px" TransferToID="listSelectedwebsites" 
                Skin="Telerik" /> 
        </div> 
        <div style="float: left;"> 
            <div style="vertical-align: middle; text-align: center;"> 
                <asp:Button ID="btnTransferright" CssClass="specialbuttons" OnClientClick="return transferRight()" 
                    Text="Add >>" runat="server" /> 
            </div> 
            <div> 
                <asp:Button ID="btnTransferleft" CssClass="specialbuttons" OnClientClick="return transferLeft()" 
                    Text="<< Remove" runat="server" /> 
            </div> 
        </div> 
        <div style="float: left;"> 
            <div> 
                Selected Website(s):</div> 
            <telerik:RadListBox ID="listSelectedwebsites" runat="server" Width="180" Height="200px" 
                Skin="Telerik" /> 
        </div> 
    </div> 
    </form> 

And the VB-script:
 Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load 
 
        Me.listSelectedwebsites.Items.Add(New RadListBoxItem("RadListBoxItem1", 1)) 
        'Me.listSelectedwebsites.Items.Add(New RadListBoxItem("RadListBoxItem2", 2)) 
        Me.listSelectedwebsites.Items.Add(New RadListBoxItem("RadListBoxItem3", 3)) 
 
        If Not Me.listSelectedwebsites.Items.Contains(New RadListBoxItem("RadListBoxItem1", 1)) Then 
            Me.listWebsites.Items.Add(New RadListBoxItem("RadListBoxItem11", 11)) 
        End If 
 
        If Not Me.listSelectedwebsites.Items.Contains(New RadListBoxItem("RadListBoxItem2", 2)) Then 
            Me.listWebsites.Items.Add(New RadListBoxItem("RadListBoxItem22", 22)) 
        End If 
 
        If Not Me.listSelectedwebsites.Items.Contains(New RadListBoxItem("RadListBoxItem3", 3)) Then 
            Me.listWebsites.Items.Add(New RadListBoxItem("RadListBoxItem33", 33)) 
        End If 
 
    End Sub 

This VB dos not work:
If Not Me.listSelectedwebsites.Items.Contains(New RadListBoxItem("RadListBoxItem1", 1)) Then
- I want to check if the value is in the 2nd listbox - if not I put it in the 1st listbox.

But I have no luck.

Hope someone can help?

Thanks.

Opening window content still cached
Hi there,

I'm having trouble trying to remove/reload a popup rad window with the correct content.  It keeps loading the same content that was there the last time.  I tried using ReloadOnShow = true but that didn't work.  Can someone help me please?

RadWindow

 

newWindow = new RadWindow();

 

 

newWindow.NavigateUrl =

"MassSelections.aspx?rnd=" + random.Next().ToString();

 

newWindow.DestroyOnClose =

true;

 

newWindow.ReloadOnShow =

true;

 

newWindow.OnClientClose =

"RefreshGrid";

 

 

RadWindowManager1.Windows.Add(newWindow);

 

RadWindowManager1.DataBind();

Thanks,
Dean
