MasterPage causing Server Error

Hi,



I have a Problem with the Telerik AsyncUpload Control. I'm using VS2010 Pro.



When I'm using this control in a single Webpage it works:



<%@ Page Language="C#" AutoEventWireup="true" CodeFile="Default.aspx.cs" Inherits="Default" %>

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

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

<head runat="server">

<title></title>

<telerik:RadStyleSheetManager id="RadStyleSheetManager1" runat="server" />

</head>

<body>

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

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

<Scripts>

<asp:ScriptReference Assembly="Telerik.Web.UI" Name="Telerik.Web.UI.Common.Core.js" />

<asp:ScriptReference Assembly="Telerik.Web.UI" Name="Telerik.Web.UI.Common.jQuery.js" />

<asp:ScriptReference Assembly="Telerik.Web.UI" Name="Telerik.Web.UI.Common.jQueryInclude.js" />

</Scripts>

</telerik:RadScriptManager>

<script type="text/javascript">

//Put your JavaScript code here.

</script>

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

</telerik:RadAjaxManager>

<div>

</div>

<telerik:RadAsyncUpload ID="RadAsyncUpload1" runat="server"

MultipleFileSelection="Automatic" TargetFolder="C:\TEMP">

</telerik:RadAsyncUpload>

<telerik:RadProgressArea ID="RadProgressArea1" runat="server">

</telerik:RadProgressArea>

<asp:Button ID="Button1" runat="server" onclick="Button1_Click" Text="Upload" />

</form>

</body>

</html>

when I'm adding a masterpage it throws me an error (see screenshot).
Here is the Code of the masterpage:

<%@ Master Language="C#" AutoEventWireup="true" CodeBehind="Site1.master.cs" Inherits="WebAppTelerik2.Site1" %>

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

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

<head runat="server">

<title> TEST </title>

<asp:ContentPlaceHolder ID="head" runat="server">

</asp:ContentPlaceHolder>

</head>

<body>

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

<asp:Label ID="lbltest" runat="server" Text="Test Label" />

<div>

<asp:ContentPlaceHolder ID="ContentPlaceHolder1" runat="server">

</asp:ContentPlaceHolder>

</div>

</form>

</body>

and the code of the contentpage:

<%@ Page Title="" Language="C#" MasterPageFile="~/Site1.Master" AutoEventWireup="true" CodeBehind="Default.aspx.cs" Inherits="WebAppTelerik2.ChildPage" %>

<asp:Content ID="Content1" ContentPlaceHolderID="head" runat="server">

</asp:Content>

<asp:Content ID="Content2" ContentPlaceHolderID="ContentPlaceHolder1" runat="server">

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

<Scripts>

<asp:ScriptReference Assembly="Telerik.Web.UI"

Name="Telerik.Web.UI.Common.Core.js">

</asp:ScriptReference>

<asp:ScriptReference Assembly="Telerik.Web.UI"

Name="Telerik.Web.UI.Common.jQuery.js">

</asp:ScriptReference>

<asp:ScriptReference Assembly="Telerik.Web.UI"

Name="Telerik.Web.UI.Common.jQueryInclude.js">

</asp:ScriptReference>

</Scripts>

</telerik:RadScriptManager>

<telerik:RadAsyncUpload ID="RadAsyncUpload1" runat="server" ChunkSize="0">

</telerik:RadAsyncUpload>

</asp:Content>

Do anyone have an idea whats the Problem.

I don't understand, why it's throwing the error and why it wants to load a SharePoint assembly...

Edit:
I do have SharePoint Foundation and SQL Express installed on the dev machine, but I think this shouldn't have something to do with this Problem.

Thanks for your help

Adding Rowcount to Tab(s)

I have 3 RadGrids each binded to a RadTab. I would like to know how I could get the RowCount for each RadGrid to show up in each Tab next to the Tab name I assigned.

A working example of what I am looking for can be seen on this link: http://www.myfxbook.com/members/forexwallstreet/wallstreet-forex-robot-real/95290 Then scroll down to TRADING ACTIVITY.

TreeList showing footers only for first level of hierarchy

I have a TreeList that contains a grid of values and I want to display a single footer at the end of the TreeList for showing the column totals for all columns that have a

FooterTemplate.

Note that the TreeList footers on Telerik's website have multiple levels for each hierarchy level. I would like to hide the footers doing something like this, but it's not working:

protected void rtlRshItems_ItemDatabound(object sender, TreeListItemDataBoundEventArgs e)
    {
        TreeListDataItem item = e.Item as TreeListDataItem;

        if (e.Item is TreeListDataItem)
        {
            var workItemId = (int) item.GetDataKeyValue("WorkItemId");
            parentId = GetParentId(workItemId);

            if (parentId == null)
                item.OwnerTreeList.ShowFooter = true;
            else
                item.OwnerTreeList.ShowFooter = false;
        }
    }

Note that GetParentId() returns null if there is no parent for the current item, meaning that I want to show a footer for that level only.

RadScheduler Synchronization with Exchange Server after deleting one event from a series of recurring events

Hi,

I have been using the RadScheduler along with the ExchangeSchedulerProvider (from the SDK) to synchronize my outlook calendar with the application. The synchronization fails in the following scenario :

From a series of recurring appointments, if a single event is deleted, the intended change is reflected in the Outlook Calendar, but even after page reload, this deletion isn't reflected in the RadScheduler. It works fine when the complete series is deleted.

I would like to know if there is a way to have the change reflected as soon as the event is deleted without having to reload the page as for the deletion of a single non recurrent event or a complete recurring series, it worked fine without page reload.

The following are the sample code snippets:

<%@ Page Language="C#" AutoEventWireup="true" CodeFile="Default.aspx.cs" Inherits="_Default" %>

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

textbox width is too short for rtl support

Editor: in the table properties the textbox width is too short for rtl.

You can see the problem in telerik's demo:
http://demos.telerik.com/aspnet-ajax/editor/examples/righttoleft/defaultcs.aspx

Scenario to reproduce:
1. In the editor (RTL support), Add a table
2. Right click on one of the cells and choose table properties
3. You can see that all textbox's width is too short. for example: When entering 3 digits or more, some of the digits are hidden.

*How can I fix this problem?

CheckBox Checked value in RadWindow

In a UserControl I have RadWindow with a CheckBox and RadButton - see attached image.
The UserControl sits in the sidebar contenplaceholder and is included in the RadAjaxManagerProxy control

<telerik:AjaxUpdatedControl ControlID="paSidebar" LoadingPanelID="raLoadingPanel"></telerik:AjaxUpdatedControl>

The code for the RadWindow:

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

<telerik:RadWindow ID="modalPopup" runat="server" Width="400px" Height="275px" Title="Subscription" Modal="true">

<ContentTemplate>

<div style="padding: 0 8px 8px 8px;">

<h2>Email messages from dealer network</h2>

<p>You can here subscribe or unsubscribe to the dealer network mailings list.</p>

<p

>From the network mailings list you receive messages of used trucks for sale or request for a truck from your colleague.</

p>

<p>

<asp:CheckBox Text="Subscribed" runat="server" ID="cbSubscribed" />

</p>

<p>

<telerik:RadButton ID="buSaveSubscribtion" runat="server" Text="Save" OnClick="BuSaveSubscribtion_Click" />

</p>

</div>

</ContentTemplate>

</telerik:RadWindow>

</telerik:RadAjaxPanel>

In the OnClick of the button I read out the value of the CheckBox.Checked:

protected void BuSaveSubscribtion_Click(object sender, EventArgs e)

{

GetUserID();

NMHG.Data.Truck_marketplace.Users.Users mailListUser = new NMHG.Data.Truck_marketplace.Users.Users();

mailListUser.UserID = userID;

mailListUser.MailMessages = cbSubscribed.Checked;

mailListUser.Update2();

if (mailListUser.Archived && cbSubscribed.Checked)

{

mailListUser.Archived = false;

mailListUser.Archive();

}

But the value don't change if I check or uncheck the CheckBox.

Please help - What do I do wrong?

Thanks in advance

Issue with Telerik RadTextbox on IE 9

Hi

There is an issue with Telerik RadTextbox on IE 9.

Background:
I am using a telerik radnumeric textbox in grid template column in a radgrid.I am connecting to SQL Server to bind the grid with data based on an SP, and when I enter numeric values into these textboxes I want them to be saved.I am using this in a RadTab setup with 3 user controls embedded in the aspx page. i.e. as shown attached. Now when I click on the save button , after changing the amount values, I expect it to connect to sql server, insert data into it and bind to it.

Issue: Clicking the save button in IE9 (only when deployed to a production environment) causes the Internet explorer to hang. The issue does not exist if turn on the compatibility mode. Also , It does not exist locally or while connecting to the production database from Visual Studio and running the solution. I used Fiddler and found out that there was a http protocol violation, and I get this message " Content length mismatch: Request header indicated 141,200 bytes, but client sent 0 bytes". Please see below the radgrid I use in my usercontrol page.

<telerik:RadGrid ID="rgStateLines" runat="server" AutoGenerateColumns="False" AllowMultiRowSelection="False"

enableajax="True" enableajaxloadingtemplate="True" GroupHeaderItemStyle-VerticalAlign="Bottom"

Width="800px" ItemStyle-HorizontalAlign="left" GridLines="None" AllowFilteringByColumn="false"

HeaderStyle-HorizontalAlign="Center" OnNeedDataSource="rgStateLines_NeedDataSource"

OnItemDataBound="rgStateLines_ItemDataBound">

<HeaderStyle Font-Size="X-Small" />

<ItemStyle HorizontalAlign="Right" VerticalAlign="Bottom" />

<AlternatingItemStyle HorizontalAlign="Right" VerticalAlign="Bottom" />

<MasterTableView AutoGenerateColumns="false" DataKeyNames="DatalistId">

<Columns>

<telerik:GridBoundColumn SortExpression="DatalistId" DataField="DatalistId" Visible="false">

</telerik:GridBoundColumn>

<telerik:GridTemplateColumn HeaderText="Description" UniqueName="Description" HeaderStyle-Width="19%"

SortExpression="Description" Visible="true" AllowFiltering="false" ItemStyle-Font-Size="X-Small"

ShowFilterIcon="false" HeaderStyle-HorizontalAlign="center">

<ItemTemplate>

<asp:Label ID="lblDescription" runat="server" Text='<%# DataBinder.Eval(Container.DataItem, "Description")%>'></asp:Label>

</ItemTemplate>

</telerik:GridTemplateColumn>

<telerik:GridTemplateColumn ItemStyle-HorizontalAlign="right" HeaderText="Amount"

UniqueName="Amount" HeaderStyle-Width="7%" SortExpression="Amount" Visible="true"

AllowFiltering="false" ShowFilterIcon="false" HeaderStyle-HorizontalAlign="Center">

<ItemTemplate>

<telerik:RadNumericTextBox ID="txtAmount" Type="Number" NumberFormat-AllowRounding="false"

Width="80px" DataType="System.Double" SelectionOnFocus="None" NumberFormat-DecimalDigits="0"

IncrementSettings-InterceptArrowKeys="false" IncrementSettings-InterceptMouseWheel="false"

EnabledStyle-HorizontalAlign="Right" runat="server" Value='<%# DataBinder.Eval(Container.DataItem, "Amount")%>'

onfocus="fnOnfocus(this)" onblur="fnOnBlur(this)">

</telerik:RadNumericTextBox>

</ItemTemplate>

</telerik:GridTemplateColumn>

</Columns>

</MasterTableView>

<ClientSettings>

<Scrolling AllowScroll="True" UseStaticHeaders="True" SaveScrollPosition="True" FrozenColumnsCount="1">

</Scrolling>

</ClientSettings>

</telerik:RadGrid>

Could you tell me if there is something I need to be aware of with regard to this set up ? Also, as to why there is the text box data binding issue in IE 9 ?

Please help.

Thanks

RadScheduler - Week view - Header dates question

Hi

In the following image, we can see all appointments from April 15 to April 20 (7 columns for 7 days) BUT in the header is showing "apr-15 - apr-20". ALSO when I add the "All-Day row" the header is now showing April 15 to April 21. Can you explain the internal logic of the end-date in the header?

Thanks

Phil
