[Solved] asp:panel navigation inside radwindow - flicker problem

Hi

I am using Radwindow as a modal popup for inline form editing. I have created a wizard, using standard 'asp:panels', inside the ContentTemplate of the Radwindow to break up the form in to smaller chunks. In each asp:panel there is a 'next' and 'back' button which is used to navigate between them. These buttons control server side functions to show/hide the various panels during navigation, and perform some form validation etc. in the background. I need this server side functionality.

The Radwindow is initially hidden on page load, but the 'ButtonAddNew' button is clicked to show it, ready to add a new item.

The problem is that during navigation between panels the page flickers badly in Chrome, Opera and IE (not in Firefox) - I guess it is posting back on the navigation button click. The panels always appear in the end, but the flicker is annoying as a user experience. I have tried putting a RadAjaxPanel around the RadWindowManager to try and stop the flicker - and get a smooth navigation - but this is not working.

Any help would be much appreciated. I have summarised some of the main code below. The Telerik controls are Q3 2010 and it's ASP.NET 3.5.

Thanks in advance.

=====================================================
Note: the Radwindow is in a usercontrol. In the Master page there is a standard ScriptManager - I'm using this as there are also some 'ASP.NET Control Toolkit' controls on some of the pages:

<asp:ScriptManager ID="ScriptManager1" runat="server"></asp:ScriptManager>

User control with Radwindow wizard:

<%@ Control language="VB" AutoEventWireup="false" CodeFile="gallery.ascx.vb" Inherits="Gallery" %>

<%@ Reference VirtualPath="~/sites_admin/admin.master" %>

<asp:Button ID="ButtonAddNew" runat="server" CausesValidation="false" OnClick="ButtonAddNew_Click" />

<telerik:RadAjaxPanel ID="RadAjaxPanel1" runat="server">

<telerik:RadWindowManager ID="RadWindowManager01" Modal="true" runat="server">

<Windows>

<telerik:RadWindow ID="RadWindowImageEdit"

Skin="kSitefinity"

AutoSize="true"

EnableEmbeddedSkins="false"

EnableEmbeddedBasestylesheet="false"

Behaviors= "Close"

VisibleTitlebar="true"

VisibleStatusbar="false"

KeepInScreenBounds="true"

EnableShadow="false"

VisibleOnPageLoad = "False"

runat="server">

<ContentTemplate>

<div style="width: 900px; padding: 6px;">

<asp:panel id="panel01" runat="server">

<asp:button id="ButtonNext01" ValidationGroup="vgText" CausesValidation="True" runat="server"

OnClick="OnClick_ButtonNext01"/>

</asp:panel>

<asp:panel id="panel02" runat="server">

<asp:button id="Buttonback02" ValidationGroup="vgText" CausesValidation="True" runat="server"

OnClick="OnClick_Buttonback02"/>

</asp:panel>

</div>

</ContentTemplate>

</telerik:RadWindow>

</Windows>

</telerik:RadWindowManager>

</telerik:RadAjaxPanel>

CODE BEHIND:

'this pops up the window the first time ready to add a new item

Protected Sub ButtonAddNew_Click(ByVal sender As Object, ByVal e As EventArgs)

'some server side code here

'show the modal popup

RadWindowImageEdit.VisibleOnPageLoad = True

End Sub

'panel navigation

Protected Sub OnClick_ButtonNext01(ByVal sender As Object, ByVal e As EventArgs)

'some validation code here

panel02.Visible = True

panel01.Visible = False

End Sub

Protected Sub OnClick_Buttonback02(ByVal sender As Object, ByVal e As EventArgs)

'some validation code here

panel02.Visible = False

panel01.Visible = True

End Sub

<telerik:RadGrid ShowFooter="True" ID="RadGrid1" runat="server" AllowFilteringByColumn="True" AllowSorting="True" GridLines="None" ShowGroupPanel="True" Skin="Web20" PageSize="15">

<MasterTableView ShowGroupFooter="True" GroupLoadMode="Client" CellSpacing="-1"></MasterTableView>

<ClientSettings AllowDragToGroup="True"></ClientSettings>

<ExportSettings OpenInNewWindow="True" ExportOnlyData="True" FileName="DataExport"></ExportSettings>

</telerik:RadGrid>

Protected Sub RadGrid1_ColumnCreated(ByVal sender As Object, ByVal e As Telerik.Web.UI.GridColumnCreatedEventArgs) Handles RadGrid1.ColumnCreated

If e.Column.DataType.Name = "DateTime" Then

CType(e.Column, Telerik.Web.UI.GridBoundColumn).DataFormatString = "{0:dd/MM/yyyy}"

End If

If e.Column.DataType.Name = "Decimal" Or e.Column.DataType.Name = "Double" Then

CType(e.Column, Telerik.Web.UI.GridBoundColumn).DataFormatString = "{0:N3}"

CType(e.Column, Telerik.Web.UI.GridBoundColumn).Aggregate = Telerik.Web.UI.GridAggregateFunction.Sum

End If

If e.Column.ColumnType = "GridBoundColumn" And counteklendi = False Then

CType(e.Column, Telerik.Web.UI.GridBoundColumn).Aggregate = Telerik.Web.UI.GridAggregateFunction.Count

CType(e.Column, Telerik.Web.UI.GridBoundColumn).FooterText = "Total : "

counteklendi = True

End If

End Sub

[Solved] Heirarchical Binding

Hi,

I have two columns available for creating a heirarchical treeview:

PositionNumber ReportsTo

10030 10004

10122 10030

10838 10030

10923 10030

11015 10030

11229 10030

11422 10030

11453 10030

When binding, I get the error "These columns don't currently have unique values".

I understand the error. There are two '11015' PositionNumber values. These are two distinct records thast have the same position number... How can I make my treeview use the values as set out above?

Actually, I don't care what the control is just so long as I can view my data heirarchically presented. If another control is more suited, do let me know!

Thanks,
Richard

RadListBoxItemCollection client API issue with forEach when using IE 8

I have the following javascript function for the OnClientTransferred event of a RadListBox. This function works fine with Firefox and Chrome but I get a javascript error with IE 8.
Here is my javascript.

    
                 <telerik:RadCodeBlock ID="RadCodeBlockMain" runat="server"> 
        
            <script type="text/javascript"> 
        
                       function OnClientTransferredHandler(sender, e) { 
        
                           var myitems; 
        
                           var radbox = $find('<%= CurrentlyTransferredValues.ClientId %>'); 
        
                           var radbox2 = $find('<%= SourceListBox.ClientId %>'); 
        
                           myitems = e.get_items(); 
        
                           myitems.forEach(function(item) { radbox.set_value(radbox.get_value() + item.get_value() + ","); }); 
        
                           radbox2.set_value(e.get_sourceListBox().get_id()); 
        
                       } 
        
             </script> 
        
               </telerik:RadCodeBlock>

The error from IE 8 is the following.
"Microsoft Jscript runtime error: Object doesn't support this property or method"
It seems to fail at line with the forEach statement.

Thanks in Advance

Change to RadTabStrip's RenderSelectedPageOnly property causing problems

In release 2011.1 519 an issue was fixed according to Telerik's release notes: Fixed: RadMultiPage: RenderSelectedPageOnly property was applied multiple times and too early in the Page Lifecycle, setting non-selected PageViews to Visible=false and causing troubles persisting state of some of the controls inside the views

This change seems to be causing me problems now.
It seems that the PageView only becomes visible now very late in the cycle! During Page.LoadComplete the selected page view seems to still be invisible, only becoming visible by PreRender.

This is making it difficult to deal with child controls of the PageView as the controls appear to be invisible until Page.PreRender, by which stage it is often too late to handle certain tasks.

Can you confirm this is correct?

The old behaviour wasn't causing me problems (as far as I am aware). Perhaps I could work around these new changes by manually setting the PageView to visible in my own code. Do you know of any workaround?

RadWindow is not displayed

Hello,

To test your RadWindow component for ajax, asp.net, i have create a page and did the same thing at the following exemple: http://demos.telerik.com/aspnet-ajax/window/examples/default/defaultcs.aspx. But i didn't get the same result: I don't have any window display in my page!
I have taken a look at "http://www.telerik.com/help/aspnet-ajax/window-overview-migrating-from-classic-to-prometheus.html" to see if there is any step missed. The explaination was not so clear to me since the links redirect to an error page "http://www.asp.net/ajaxlibrary/act.ashx".

You may have an idea about the origin of this problem. Thank You for help.
