Loading Panel JScript Timeout

Hi:

I have a long running process that I placed a Loading Panel on the form, but if it take say 92 seconds, it throws the following exception:
Microsoft JScript runtime error:
Sys.WebForms.PageRequestManagerTimeoutException: The server request timed out.
How can I set the timeout?

Using CSS style from skin on non Rad Controls

How can I apply the same CSS style that is being used by my Rad Controls onto another control like a asp:label? Ex. I have all of my Rad controls set to use the Black skin and I want all of my standard asp:labels to have the same text/font/etc that is being used by Rad-Slider

Missing Ajax functionality when adding Grid dynamically

Hi,

i am new to telerik. I have built a user control with the following code:

<%@ Control Language="C#" AutoEventWireup="true" CodeFile="WebUserControl.ascx.cs" Inherits="WebUserControl" Codebehind="WebUserControl.ascx.cs" ClassName="WebUserControl" %>

<%@ Register Assembly="Telerik.Web.UI" Namespace="Telerik.Web.UI" TagPrefix="telerik" %>

<telerik:RadScriptManager ID="RadScriptManager1" runat="server"></telerik:RadScriptManager>

<asp:SqlDataSource ID="GridSource" runat="server" ConnectionString="<%$ ConnectionStrings:Test%>" SelectCommand="SELECT * FROM Evt"> </asp:SqlDataSource>

<telerik:RadGrid ID="RadGrid1" runat="server" CellSpacing="0"

DataSourceID="GridSource" AllowFilteringByColumn="True" AllowPaging="True"

AllowSorting="True" ShowGroupPanel="True">

<ClientSettings AllowDragToGroup="True">

<Scrolling AllowScroll="True" UseStaticHeaders="True" />

</ClientSettings>

<MasterTableView>

<CommandItemSettings ExportToPdfText="Export to PDF"></CommandItemSettings>

<RowIndicatorColumn FilterControlAltText="Filter RowIndicator column">

<HeaderStyle Width="20px"></HeaderStyle>

</RowIndicatorColumn>

<ExpandCollapseColumn FilterControlAltText="Filter ExpandColumn column">

<HeaderStyle Width="20px"></HeaderStyle>

</ExpandCollapseColumn>

<EditFormSettings>

<EditColumn FilterControlAltText="Filter EditCommandColumn column"></EditColumn>

</EditFormSettings>

</MasterTableView>

<FilterMenu EnableImageSprites="False"></FilterMenu>

<HeaderContextMenu CssClass="GridContextMenu GridContextMenu_Default"></HeaderContextMenu>

</telerik:RadGrid>

<telerik:RadAjaxManager ID="RadAjaxManager1" runat="server">

<AjaxSettings>

<telerik:AjaxSetting AjaxControlID="RadGrid1">

<UpdatedControls>

<telerik:AjaxUpdatedControl ControlID="RadGrid1"

LoadingPanelID="RadAjaxLoadingPanel1" />

</UpdatedControls>

</telerik:AjaxSetting>

</AjaxSettings>

</telerik:RadAjaxManager>

When i put it in a content tag in my html code it works fine. But i would like to add the control via a click on a button.
So on the page where the button is located i wrote the following in the code behind:

using System;

using System.Collections.Generic;

using System.Linq;

using System.Web;

using System.Web.UI;

using System.Web.UI.WebControls;

public partial class SiteMaster : System.Web.UI.MasterPage

{

WebUserControl ctrl;

protected void Page_Load(object sender, EventArgs e)

{

Button BTN1 = new Button();

BTN1.Click += new EventHandler(BTN_Click);

this.MenuContent.Controls.Add(BTN1);

}

protected void BTN_Click(object sender, EventArgs e)

{

ctrl = (WebUserControl)LoadControl("~/WebUserControl.ascx");

this.MenuContent.Controls.Add(ctrl);

}

Has anybody an idea why this doesn't work or a solution so ajax functionality will be enabled for this purpose?

Thanks
Simon

Radcalender inside Repeater - Events not working

Hi,
I am using Rad Calender inside a Repeater.

<asp:Repeater ID="ResultRpt" runat="server">

<ItemTemplate>

<telerik:RadCalendar Style="width: 191px; height: 123px" ID="RadCalendar1" runat="server"

EnableMonthYearFastNavigation="false" AutoPostBack="true" MultiViewColumns="1"

MultiViewRows="1" EnableMultiSelect="true">

</telerik:RadCalendar>

<telerik:RadToolTipManager Width="270px" Height="135px" Style="font-size: 11px" RelativeTo="Element"

ID="RadToolTipManager1" runat="server" OffsetX="7" Position="MiddleRight" OnAjaxUpdate="RadToolTipmanager1_AjaxUpdate" Skin="Telerik" AutoCloseDelay="90000" </telerik:RadToolTipManager>

</ItemTemplate>

</asp:Repeater>

this is my rad ajax manager

<telerik:RadAjaxManager ID="RadAjaxManager1" runat="server">

<AjaxSettings>

<telerik:AjaxSetting AjaxControlID="RadCalendar1">

<UpdatedControls>

<telerik:AjaxUpdatedControl ControlID="RadCalendar1" LoadingPanelID="RadAjaxLoadingPanel1">

</telerik:AjaxUpdatedControl>

</UpdatedControls>

</telerik:AjaxSetting>

<telerik:AjaxSetting AjaxControlID="calMarker">

<UpdatedControls>

<telerik:AjaxUpdatedControl ControlID="RadCalendar1" LoadingPanelID="RadAjaxLoadingPanel1">

</telerik:AjaxUpdatedControl>

<telerik:AjaxUpdatedControl ControlID="calMarker" LoadingPanelID="RadAjaxLoadingPanel1">

</telerik:AjaxUpdatedControl>

</UpdatedControls>

</telerik:AjaxSetting>

</AjaxSettings>

<ClientEvents OnRequestStart="RequestStart" OnResponseEnd="ResponseEnd" />

</telerik:RadAjaxManager>

<telerik:RadAjaxLoadingPanel ID="RadAjaxLoadingPanel1" runat="server" Skin="WebBlue" />

The tool tip on the date is not working . And the loading panel is not working for the onclick on the rad calender(instead the page is postbacking) .



The calmarker control is a panel bar which is also inside the repeater its loading panel is also not working .



These was working when there was no repeater. After i put the repeater control the issue started.

NullReferenceException in RadAjaxManager.AjaxSettings.AddAjaxSetting()

Hi,

I have a Page Controller design pattern, so I have a base Page class that defines and dumps out a RadAjaxManager control. The (edited) base class is:

                    using System;         
            using System.Collections.Generic;         
            using System.Linq;         
            using System.Text;         
            using System.Web;

            using xxx.yyy.ASPNET.Security;         
            using xxx.yyy.Client;         
            using xxx.yyy.Client.Security;         
            using xxx.yyy.Core;         
            using Telerik.Web.UI;

                    #region ~ Properties ~         
                     
                    public RadAjaxManager AjaxManager         
                    {         
                        get { return _radAjaxManager; }

                        Form.Controls.Add(_radAjaxManager);         
                     
                        if (!ClientScript.IsClientScriptBlockRegistered(_radAjaxManager.ClientID))         
                        {         
                            ClientScript.RegisterClientScriptBlock(_radAjaxManager.GetType(), _radAjaxManager.ClientID,GenerateJavascript(),true);         
                        }         
                                 
                     
                        base.OnLoad(e);         
                    }         
                     
                    protected virtual RadAjaxManager BuildRadAjaxManager()         
                    {         
                        RadAjaxManager radAjaxManager = new RadAjaxManager();         
                        radAjaxManager.ID = "radAjaxManager";            
                        return radAjaxManager;         
                    }         
                     
                    private string GenerateJavascript()

                        StringBuilder sb = new StringBuilder();         
                     
                                 
                     
                        sb.Append("\n\nfunction migGetRadAjaxManager() {\n");         
                        sb.Append("\tvar ajaxManager=$find(\"" + _radAjaxManager.ClientID + "\");\n");         
                        sb.Append("\treturn ajaxManager;\n");         
                        sb.Append("}\n\n");         
                     
                     
                        return sb.ToString();         
                    }         
                }         
            }         
                     
                     

(The RadAjaxManager is added into the Form and appears in the rendered HTML)

In the derived page, I want to add an AjaxSetting programmatically (as per http://www.telerik.com/help/aspnet-ajax/ajxaddajaxsettingsprogrammatically.html) in the Page_Load():

                    protected void Page_Load(object sender, EventArgs e)         
                    {         
                        AjaxManager.AjaxRequest += new RadAjaxControl.AjaxRequestDelegate(AjaxManager_AjaxRequest);         
                                 
                        AjaxManager.AjaxSettings.AddAjaxSetting(btnCancel0, pnlScriptInjector);         
                                 
                    }         

But this results in the exception:

Object reference not set to an instance of an object.

AjaxManager.AjaxSettings.AddAjaxSetting(btnCancel0, pnlScriptInjector);

                       at Telerik.Web.UI.AjaxSettingsCollection.AddAjaxSetting(Control ajaxifiedControl, Control updatedControl)

               at System.Web.UI.Control.OnLoad(EventArgs e)

Inspecting the variables in the debugger and I can't see anything that is null.

Could you please tell me why is this happening? Am I using it right?

Select Row When Clicking CheckBox

Happy Monday, everyone!

Our users have requested that when we use the RadListBox with CheckBoxes that when they click on a checkbox that the entire row become focused - like it does when they click on the text of a row.

I've tried setting focus manually in the ItemChecked event with the following but no matter what I do I can't get this accomplished.

event.get_item().select();

event.get_item().get_element().focus();

Anyone managed to get this working?

Thanks!

Unable to start_edit() a node if it is the only child of parent.

Hi,
  I'm not able to start_edit() a new node at the 2nd Level client-side if the parent node does not have any child previously and this is the only child.

Below is the code I've written to add a new node.

   function AddNode(parentNode)
   {
   var tree = parentNode.get_treeView();
   tree.trackChanges();
   var node = new Telerik.Web.UI.RadTreeNode();
   node.set_text("New Node");
   node.set_value("New Node");
   parentNode.get_nodes().add(node);
   node.select();
   tree.add_nodeEdited(NodeAdded);
   tree.commitChanges();
   node.startEdit();
   }

at the node.startEdit() statement it throws an error as: "htmlfile: Can't move focus to the control because it is invisible, not enabled, or of a type that does not accept the focus."

Please note that the ExpandMode of the Nodes are "WebService"

The Ribbonbar is a great control. One small UI request... I don't think there should be a line underneath selected tabs as can be seen in the attached screen capture
