RadNumericTextBox does not behave as desired

The controls I have put on my page (RadNumericTextBox) do not respond when incorrect inputs are typed into the textbox. The spin buttons also do not work as required, what could the issue be? I have put references to the telerik controls on the page and all that but the text box behaves as a normal text box. Any help would be appreciated.

Thanks.

RadComboBox & ModalPopupExtender Issue

I'm using a RadComboBox within an ModalPopupExtender, and although the control populates, the matches (dropdown) shows in the background -- i can still use my arrow keys to navigate the list and select from it, but it isn't really useable if the user can't see it

I tried changing the zindex of the RadComboBox control, but that didn't solve the problem.

thanks!

BindtoList Sample error Method not found: 'Void System.Web.UI.ScriptManager.RegisterStartupScript

I get the following error when I try to run the BindtoList sample (Dec 2008) for the scheduler:
Method not found: 'Void System.Web.UI.ScriptManager.RegisterStartupScript(System.Web.UI.Page, System.Type, System.String, System.String, Boolean)'.

Does anyone know how to resolve this and get this sample to run?

Upload Timeout

Our system allows the uploads of files, it will also automatically log out a user if there is no activity for 10 minutes. The problem is this, a user entered the system, started to upload a file and then left the computer. Since there was no activity for 10 minutes the user was automatically logged off, which interrupted the process of transferring the file. Is there anyway of preventing a user being logged out if there is an active process running?

Below are the lines of code definining the period of time before being logged off, and the timeout time for the upload process. Thanks.

<

forms loginUrl="AutorizationChecker.aspx" protection="Validation" timeout="10"/>

<

httpRuntime maxRequestLength="102400" executionTimeout="3600"/>

Response end delay

I recently switched over from the old controls to the ASP.NET ones. What I'm seeing though is that the AJAX performance is much slower with the new ones.

I am using the RadAjaxManager to load portions of my page...sometimes large portions. In cases where I load a large portion of the page I see the page appear behind my loading panel, and then it takes about another 7 seconds (in IE) for the loading panel to go away and the client-side response end handler to get called.

The markup returns quickly and is rendered by the browser within 3 seconds, but what on Earth is going on the other 7 seconds is a mystery. I'm guessing that there is a bunch of client-side script running, but this is a reaaaally long delay. With the old RadAjaxManager it was much quicker.

Any suggestions around what I can do to debug it, and try to figure out why?

By the way, the delay is less than half in Firefox of what it is in IE.

Thanks,
Ross

Returning args from closed window

Having a problem is returning the a value when closing a window.

The parent page is set up using the RadWindowManager

<telerik:RadWindowManager ID="RadWindowManager1" runat="server">

<telerik:RadWindow runat="server" Behavior="Default" InitialBehavior="None" Left=""

Modal="True" NavigateUrl="GroupSearchPopup.aspx" OpenerElementID="<%# lnkGroupSearch.ClientID %>"

Style="display: none;" ReloadOnShow="true" ClientCallBackFunction="OnGroupCallback"

Title="Donation Group Search" Top="" Width="450px" Height="300px" ID="rwGroupSearch">

</telerik:RadWindow>

<telerik:RadWindow ID="rwDonorSearch" runat="server" Behavior="Default" Width="550px"

Height="500px" InitialBehavior="None" Left="" Modal="True" NavigateUrl="DonorSearchPopup.aspx"

ReloadOnShow="true" OnClientClose="OnDonorSearchClose" Style="display: none;"

Top="" OpenerElementID="<%# lnkPersonSelect.ClientID %>"

OnClientDragEnd="OnClientDragEnd">

</telerik:RadWindow>

</Windows>

</telerik:RadWindowManager>

Parent client side code to handle the Window close

function OnDonorSearchClose(sender, eventArgs) {

alert(

"action on close = " & eventArgs);

oValue = eventArgs;

if (oValue.action > 0) {

// Set a hidden field to the value

document.getElementById(

'<%= Me.hfPersonID.ClientID %>').Value = oValue;

document.getElementById(

'<%= Me.btnScriptUpdate.ClientID %>').click();

}

}

Modal window client code

function CloseWithArg(sender, eventArg) {

var currentWindow = GetRadWindow();

alert(

"Arg = " + eventArg);

currentWindow.argument = eventArg;

currentWindow.close();

}

The alert in the modal CloseWithArg function displays the correct value

but the alert on the parent OnDonorSearchClose function displays only a 0. Even the text portion of the alert is not displayed.

Any hints as to what I'm doing wrong?

Thanks

Changing columns visiblity via Ajax

I've a problem with showing and hiding a column via an ajax request. When I set the column's Visible property to false, the column is hidden, but when set back to true the column does not reappear.

Try the following page

ASPX

    
            <%@ Page Language="C#" AutoEventWireup="true" CodeFile="Default.aspx.cs" Inherits="_Default" %> 
        
            <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.1//EN" "http://www.w3.org/TR/xhtml11/DTD/xhtml11.dtd">

                <title>Untitled Page</title> 
        
            </head> 
        
            <body> 
        
                <script type="text/javascript"> 
        
                    function firePostBack(arg) 
        
                    { 
        
                        $find('<%=ajaxManager.ClientID %>').ajaxRequest(arg); 
        
                    } 
        
                </script> 
        
                <form id="form1" runat="server">

                </form> 
        
            </body> 
        
            </html>

C#

    
            using System; 
        
            using System.Data;

            using System.Collections.Generic; 
        
            using Telerik.Web.UI; 
        
            public partial class _Default : System.Web.UI.Page  
        
            { 
        
                protected void grid_NeedDataSource(object source, Telerik.Web.UI.GridNeedDataSourceEventArgs e) 
        
                { 
        
                    DataTable table = new DataTable(); 
        
                    table.Columns.Add("col1"); 
        
                    table.Columns.Add("col2"); 
        
                    table.Rows.Add("data1", "data2"); 
        
                    table.Rows.Add("data3", "data4"); 
        
                    table.Rows.Add("data5", "data6"); 
        
                    grid.DataSource = table; 
        
                } 
        
                protected void ajaxManager_AjaxRequest(object sender, AjaxRequestEventArgs e) 
        
                { 
        
                    grid.Columns.FindByUniqueName("col2").Visible = !grid.Columns.FindByUniqueName("col2").Visible; 
        
                } 
        
            }

When you click the fire button an ajax request is fired and the second column's visiblity is toggled.

The first click hides the column, which is fine, but the second click doesn't show it again..

Any ideas?

Thanks,

But today I discovered that I cannot set the CssClass in the RadTreeNodeData class.. it does include the disabledCssClass, HoveredCssClass etc etc.. but not the default CssClass.

Does anybody know a workaround/fix for this ?

Thanks,
