Questions on UI for ASP.NET AJAX Forum

The following issue occurs in Chrome 9.0.597.98 beta. I can't reproduce it in Firefox or IE. Here goes.

So, I have the following javascript running on every page in my web app:

var TIMEOUT_DURATION = 1200000;

var timerID = null;

function onLogoutTimeout()

{

$("a").each(function ()

{

var isLogoutLink = jQuery(this).attr("id").toString().search(new RegExp(/signoutLink/i));

if (isLogoutLink >= 0)

document.location = this.href;

});

}

function onResetTimer()

{

clearTimeout(timerID);

timerID = setTimeout("onLogoutTimeout()", TIMEOUT_DURATION);

}

$(document).ready(function ()

{

timerID = setTimeout("onLogoutTimeout()", TIMEOUT_DURATION);

$(this).mousemove(function (e) { onResetTimer() });

$(this).keydown(function (e) { onResetTimer() });

});

Basically, it sets a timeout so that if a user is idle for to long, it will log them out. You'll notice that I'm using jQuery. I'm using the jQuery that comes packages with the Telerik controls. I'm using 2010.3.1317.40. The following is a simple page with a RadGrid on it:

<%@ Page Title="" Language="C#" MasterPageFile="~/Includes/MasterPages/GofrPortalMasterPage.master"

AutoEventWireup="true" CodeFile="Default.aspx.cs" Inherits="Organization_Admin_Users_Default"

Culture="auto" UICulture="auto" %>

<asp:Content ID="Content1" ContentPlaceHolderID="Head" runat="Server">

</asp:Content>

<asp:Content ID="Content2" ContentPlaceHolderID="PageTitle" runat="Server">

<asp:Localize runat="server" meta:resourcekey="PageTitle"></asp:Localize>

</asp:Content>

<asp:Content ID="Content3" ContentPlaceHolderID="MainContent" runat="Server">

<telerik:RadCodeBlock ID="rcbCodeBlock" runat="server">

<script type="text/javascript">

if (typeof SubscribeToWindowClose == "function")

{

SubscribeToWindowClose("rwCreateUser", OnCreateUserWindowClose);

SubscribeToWindowClose("rwEditUser", OnCreateUserWindowClose);

}

function OnCreateUserWindowClose(args)

{

var userGridAjaxPanel = $find("<%= rapUserGrid.ClientID %>");

userGridAjaxPanel.ajaxRequest("Rebind");

}

</script>

</telerik:RadCodeBlock>

You can add users by clicking on the plus icon or modify them by clicking on their

email address.<br />

<br />

<telerik:RadAjaxPanel ID="rapUserGrid" runat="server" OnAjaxRequest="OnUserGridAjaxRequest"

LoadingPanelID="loadingPanel">

<telerik:RadGrid ID="rgUser" runat="server" EnableEmbeddedSkins="False" Skin="GofrDefault"

GridLines="None" AutoGenerateColumns="False" OnItemDeleted="OnItemDeleted" OnNeedDataSource="OnNeedUsersDataSource"

OnDeleteCommand="OnDeleteUser" AllowSorting="true">

<MasterTableView DataKeyNames="AssetID" CommandItemDisplay="Top" meta:resourcekey="GridMasterTableView">

<Columns>

<telerik:GridButtonColumn ButtonType="ImageButton" ConfirmText="Are you sure you want to delete this user?"

ConfirmTitle="Confirm Delete" UniqueName="DeleteColumn" CommandName="Delete" ImageUrl="~/Skins/GofrDefault/Grid/Delete.gif"

ItemStyle-Width="1em" meta:resourcekey="UserGridDeleteColumn">

</telerik:GridButtonColumn>

<telerik:GridHyperLinkColumn HeaderText="Email Address" SortExpression="EmailAddress"

ItemStyle-Width="30em" DataTextField="EmailAddress" DataNavigateUrlFields="AssetID"

DataNavigateUrlFormatString="javascript:OpenRadWindow_NoReturn('rwEditUser', {{'UserID':{0}}})"

meta:resourcekey="UserGridEmailColumn">

</telerik:GridHyperLinkColumn>

<telerik:GridBoundColumn DataField="FirstName" HeaderText="First Name" SortExpression="FirstName"

meta:resourcekey="UserGridFirstNameColumn">

</telerik:GridBoundColumn>

<telerik:GridBoundColumn DataField="LastName" HeaderText="Last Name" SortExpression="LastName"

meta:resourcekey="UserGridLastNameColumn">

</telerik:GridBoundColumn>

</Columns>

<CommandItemTemplate>

<div class="gridCommandItemDiv">

<asp:HyperLink runat="server" CssClass="gridCommandItem" Text="<%$ Resources:VirtualOfficeResources, CreateUserLabel %>"

NavigateUrl="javascript:OpenRadWindow_NoReturn('rwCreateUser', null, null)" ImageUrl="~/Skins/GofrDefault/Grid/AddRecord.gif"

ToolTip="Create User"></asp:HyperLink>

</div>

</CommandItemTemplate>

</MasterTableView>

<FilterMenu EnableEmbeddedSkins="False">

</FilterMenu>

<HeaderContextMenu EnableEmbeddedSkins="False">

</HeaderContextMenu>

</telerik:RadGrid>

</telerik:RadAjaxPanel>

<telerik:RadAjaxLoadingPanel ID="loadingPanel" runat="server" Transparency="0" IsSticky="true">

<asp:Panel ID="innerLoadingPanel" runat="server" CssClass="innerLoadingPanel">

<table>

<tr>

<td>

<asp:Image runat="server" ImageUrl="~/Skins/GofrDefault/Common/loading.gif" />

</td>

<td style="color: White; padding-left: 1em; font-size: larger">

<asp:Localize runat="server" Text="<%$ Resources:VirtualOfficeResources, LoadingLabel %>"></asp:Localize>

</td>

</tr>

</table>

</asp:Panel>

<ajax:AlwaysVisibleControlExtender runat="server" HorizontalSide="Center" VerticalSide="Middle"

VerticalOffset="150" HorizontalOffset="100" TargetControlID="innerLoadingPanel">

</ajax:AlwaysVisibleControlExtender>

</telerik:RadAjaxLoadingPanel>

</asp:Content>

So basically what is happening is that when I push the delete button next to a user, it is firing the onLogoutTimeout() javascript timeout. The confirm dialog comes up, on confirm the server side event gets fired, and then this timeout event gets fired, which logs a user out. Not sure why this is happening. Any help would be appreciated.

Radwindow won't open if 2 requiredfieldvalidator's on the page

Here is a code sample of my test page.

<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="junk2.aspx.cs" Inherits="Testing.junk2" %>

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

<%--<%@ Register Src="~/CustomControls/Header.ascx" TagPrefix="uc1" TagName="Header" %>--%>

<!DOCTYPE html>

<html xmlns="http://www.w3.org/1999/xhtml">

<head runat="server">

<title></title>

</head>

<body>

<form id="form1" runat="server">

<div>

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

<telerik:RadTextBox runat="server" ID="txtFriendly" Width="400px" Skin="Silk"></telerik:RadTextBox>

<asp:RequiredFieldValidator runat="server" ID="RequiredFieldValidator1" ControlToValidate="txtFriendly"

Display="Dynamic" ErrorMessage=" * required" CssClass=" text-danger"/>

<telerik:RadTextBox runat="server" ID="txtSubject" Width="400px" Skin="Silk" ></telerik:RadTextBox>

<%-- <asp:RequiredFieldValidator runat="server" ID="RequiredFieldValidator5" ControlToValidate="txtSubject"

Display="Dynamic" ErrorMessage=" * required" CssClass=" text-danger"/>

--%>

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

</telerik:RadWindowManager>

<asp:Button runat="server" ID="btntest" OnClick="btntest_Click" Text="test" CausesValidation="false" />

</div>

</form>

</body>

</html>

And the codebehind:

protected void btntest_Click(object sender, EventArgs e)

{

RadWindow newWindow = new RadWindow();

newWindow.NavigateUrl = "http://www.google.com";

newWindow.VisibleOnPageLoad = true;

RadWindowManager1.Windows.Add(newWindow);

}

If I comment out either (or both) of the 2 RequiredFieldValidator's, the modal displays. It doesn't matter which one is commented.

If both are on the page, I get no modal dialog.

We are using v2016.3.1018.45

Can't change default font size on pdf export?

Hi

I am exporting a grid to pdf following various examples, and I am using the RadGrid_ItemCreated event successfully to have alternating row styles but I haven't found any way to set the font size.

Existing code is :

Protected Sub FormatGridItem(item As GridItem)
If TypeOf item Is GridHeaderItem Then
For Each cell As TableCell In item.Cells
cell.Style("font-family") = "Arial"
cell.Style("text-align") = "left"
cell.Style("vertical-align") = "middle"
Next
End If

' Dim dataItems As GridItem() = View.GetItems(GridItemType.Item)
If TypeOf item Is GridDataItem Then
item.Style("Font-family") = "Arial"
Select Case item.ItemType

Case GridItemType.Item
item.Style("background-color") = "#DDDDDD"
item.Style("Font-size") = "10pt" ' no effect
Exit Select
Case GridItemType.AlternatingItem
item.Style("background-color") = "#FFFFFF"
item.Style("Font-size") = "10pt" ' no effect
Exit Select
Case GridItemType.Header
item.Font.Bold = True
Exit Select
Case GridItemType.Footer
item.Style("background-color") = "#FFFFFF"
Exit Select
End Select
End If
End Sub

how can I set the font size? I have tried using px, pt, and em but it does not change.

Please advise. I haven't seen any code on this; maybe it is not possible or has to be done somewhere else entirely.

Thanks

Clive

var rotatorElement = document.getElementById("ContentPlaceHolder1_RadRotator1" + "_Div");

rotatorElement.RadResize();

}

</script>

Error : RadResize undefined.

Thanks in advance for your help

how to do multiple pdf exports

I have a grid I made and users can export it into pdf via a button.
what they want is to select a number of users that each make their own pdf and to just export all their grids into pdf's into a zip.

is there any way to do this?

I could possibly make each grid on the page at one time but how to export them all at once into separate pdf's

telerik.web.ui.skins.dll missing

I've just run the upgrade wizard from an early Q2 2011 to Q3 2011 and got the expected error in respect of skins now being outside the web.ui.dll file.

I am however having trouble finding the skins.dll file to reference - I've searched all my hard disks to no avail. It's certainly not in the project /bin folder either. I then looked for the location that the installer puts *any* of the Q3 2011 telerik files and couldn't find a directory - I presume it just inserts the relevant files as necessary in a project rather than store in /program files or somesuch.

How should I go about getting the skins.dll so that I can put it in my /bin and reference it in my project?

Thanks
Rich.

Telerik.Web.UI.WebResource.axd - Request timed out

Hi,

We've got some serious problems with randomly "Request timed out" error in some cases on our web application during requesting Telerik.Web.UI.WebResource.axd.

In some circumstances the request to Telerik.Web.UI.WebResource.axd is processed more than 2 minutes, in each case (when hit the page with Telerik on it) and it times out. Due to that, CPU Load increase to 100% (there are many requests to Telerik.Web.UI.WebResource.axd which waiting to be handled), and the effect is massively disaster - Users cannot use the application because it's overloaded.

In such situation - IIS Reset sometimes help, sometimes not.

It occurs 4 times in last month, and this issue is taking about 2-4 hours every time when it occur. After that - the request to Telerik.Web.UI.WebResource.axd is processed normally. I'm not sure if the traffic has something to do with it, because it occurred once after 9PM (the biggest traffic is approximately during the day).

What's the most funny thing - this request which is in some circumstances "Time Out" weight 12,4 KB, and contains Telerik controls CSS styles.

In attachment - some pictures with errors. We're using the Telerik version: 2013.2.611.40
I would be grateful for any help, because we're running out of ideas, and yesterday this error blocked our application for all day :(

Greetings,
Marcin

Problem with display of RadMenu within a RadPanelBar

I have a RadMenu within a RadPanelBar.

(The actual arrangement is RadPanelBar-Items-RadPanelItem-ContentTemplate and then a set of Bootstrapped Divs containing various controls.)

The problem is that, unlike the RadComboBoxes within the RadPanelBar, the RadMenu will not expand outside the RadPanelBar area. Much of the fairly long menu is not visible and not accessible.

Suggestions?

Style the Rad Spell Dialog

Dear Support,

I am using the RadSpell control and linking it to a RadTextbox. That part works great.

<telerik:RadSpell RenderMode="Lightweight" Skin="Metro" ID="RadSpell1" runat="server" ButtonType="ImageButton" ControlToCheck="txtDescription" SpellCheckProvider="PhoneticProvider" SupportedLanguages="en-US,English" OnClientDialogClosed="SpellCheckDone" />

However, the font size and font name (Times Roman) in the popup dialog do not match the rest of my screen. I've tried setting the CssClass for the control, the font name and font size properties, and everything else I can think of but with no success. Can you provide a CSS example (or other mechanism) by which I can set the font and font size of the labels and buttons within the dialog. I attached a screenshot with arrows pointing to the text components I am referring to.

Thanks,

Mike
