I am trying to control the format that excel chooses for my cells when I do an ExportToExcel() of my grid.

I have a column that holds percentage values. In the column declaration, I have the following:

DataFormatString

="{0:N1}%" FooterAggregateFormatString="{0:N1}%"

But although both format strings are the same, in the excel sheet that is generated, the data rows are formatted with the "Number" category, and so they have values like "0.36", while the footer is formatted with the "Percentage" category and has values like "36.4%" (which is what I want).

I have tried at least a dozen things and I can't get the data rows to display in a percentage format. Is there any way to control the format of data rows when you use ExportToExcel?

[Solved] RadGrid renders different in IE7, IE8 and IE8 Compatibility Mode

Hello,

I am using RadControls for ASP.NET AJAX (v20091.527.20) and I am experiencing different display rendering in IE8 and IE8 Compatibility Mode. Please see the attached screen shot.

As you can see, the columns widths are different depending on the browser mode. I have also tried using IE7 but it renderes the same as IE8 Compatibility Mode.

Also, I have three custom filtering columns based on the GridTemplateColumn class. The second one is set to stretch over five adjacent columns. You can see it works fine in IE8 but gets clipped in IE8 Compatibility Mode (and also in IE7).

How can I fix this display issue?

Thanks,

RadFilter Filter On A Different Page

I have so many different UserControls and RadControls on my page that it seems to be conflicting with the RadFilter. I am trying to open a RadWindow with the RadFilter in the Content Template. Four problems arise for me when doing this.

1. Clicking the Add Expression button does nothing on first click, a second click does what is expected.
2. Showing an expression based on a DateTime field throws off the style. The textbox width is very small, the images do not show up, and the alternate text shows up.
3. Any skin other than Default does not show correctly.
4. When clicking Apply, I get "Microsoft JScript runtime error: '_events' is null or not an object". When I click Continue in Visual Studio, the filter does get applied.

I think a lot of this could be solved if I were able to put the RadFilter on a seperate page. I understand how the RadFilter interacts with the FilterContainer, in my case a RadGrid but I am hoping that there is a solution as our setup is very complicated.

We use dynamic tab loading using the RadTabStrip control. Each tab contains a UserControl which have a myriad of RadControls including RadSplitter, RadGrid, RadToolbar, RadWindow.

<telerik:RadAjaxManagerProxy ID="rampDomestic" runat="server">

<AjaxSettings>

<telerik:AjaxSetting AjaxControlID="btnApply">

<UpdatedControls>

<telerik:AjaxUpdatedControl ControlID="rgDomestic" LoadingPanelID="ralpDomestic" />

</UpdatedControls>

</telerik:AjaxSetting>

<telerik:AjaxSetting AjaxControlID="rfAdvanced">

<UpdatedControls>

<telerik:AjaxUpdatedControl ControlID="rfAdvanced" LoadingPanelID="ralpDomestic" />

</UpdatedControls>

</telerik:AjaxSetting>

</AjaxSettings>

</telerik:RadAjaxManagerProxy>

<telerik:RadAjaxLoadingPanel ID="ralpDomestic" runat="server"></telerik:RadAjaxLoadingPanel>

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

<Windows>

<telerik:RadWindow ID="rwAdvancedFilter" runat="server" Behaviors="Move, Resize, Close" Title="Advanced Shipment Filter" Modal="true" Width="400" Height="400">

<ContentTemplate>

<telerik:RadFilter ID="rfAdvanced" runat="server" FilterContainerID="rgDomestic" ShowApplyButton="false" Style="margin:10px 0 0 10px;">

</telerik:RadFilter>

<asp:Button ID="btnApply" runat="server" Text="Apply" OnClientClick="HideAdvancedFilter" /><asp:Button ID="btnCancel" runat="server" Text="Cancel" OnClientClick="HideAdvancedFilter" />

</ContentTemplate>

</telerik:RadWindow>

</Windows>

</telerik:RadWindowManager>

Thanks for any help.

1/1/1980 RDP

If I wanted to change the default min date for RadDatePickers for our entire site, would I simply change the value in Telerik.Web.UI.xml?

<member name="P:Telerik.Web.UI.RadDatePicker.MinDate">

<summary>

Gets or sets the minimal range date for selection.

Selecting a date earlier or equal to that will not be allowed.

</summary>

<remarks>

This property has a default value of <strong>1/1/1980</strong>

</remarks>

[Solved] Menu drop downs hidden with fixed header

I am working on a website which is for IE only but it must run in ie 6 and up. We have a fixed header with CSS styles and in that header we have a rad menu. The only way we can get the rad menu drop down menu to display properly is by modifying the doc type from:

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

to

<!

DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN">

What is happening is the menu drop down executs but it is hidden behind the main web content container. The main web content container is compised of a rad splitter. However, when we change the doc type to 4.0 so that the site works in IE8 with compatiblity mode turned on the page layout works but many of our other pieces are broken because then need the doc type to be xhtml.

Basically we have

fixed header
rad menu
-------------
m| main
e| content
n|
u|

The CSS I am use to accomplish this is:

html{

height: 100%;

margin: 0px;

padding: 0px;

}

* html html {

height: 100%;

margin: 0px;

padding: 0px;

}

body {

height:100%;

MAX-HEIGHT: 100%

border: 0px;

padding:0px;

margin: 0px;

padding-top:94px;

background:#fff;

font-family:arial, verdana, sans-serif;

font-size:76%;

overflow: hidden;

}

* html body {

PADDING-LEFT: 0px; PADDING-RIGHT: 0px; PADDING-TOP: 99px;

}

#container {

width: 100%;

height:100%;

top: 120px;

right: 0px;

left: 0px;

text-align: left;

overflow: auto;

}

* HTML #contianer

{

height:100%;

}

#header {

position: absolute;

height:90px;

width:100%;

overflow: hidden;

top: 0px;

left: 0px;

border-bottom: #ccc 4px solid;

}

* HTML #header

{

overflow:visible;

HEIGHT: 90px

}

Any help you can offer would be much appreciated thanks.

get items of RadMenuItems

Good day!
I have such a structure of menu:

<telerik:RadMenu ID="RadMenu_Clients" runat="server" OnItemClick="RadMenu_Clients_ItemClick">
                                    <Items>
                                        <telerik:RadMenuItem Text="Профиль" Value="profile" ImageUrl="App_Themes/Theme1/Image/down.png">
                                            <GroupSettings ExpandDirection="Down"></GroupSettings>
                                            <Items>
                                                <telerik:RadMenuItem Text="Настройки аккаунта" Value="settings" />
                                                <telerik:RadMenuItem Text="Данные предприятия" Value="data"/>
                                                <telerik:RadMenuItem Text="Объекты" Value="objects"/>
                                            </Items>

                                                <telerik:RadMenuItem Text="Информация о моих заказах" Value="order_info"/>
                                            </Items>
                                        </telerik:RadMenuItem>
                                    </Items>
                                </telerik:RadMenu>

SelectedValue is not updated on server side

Hello!

I have two "linked" comboboxes - Area (ddlArea) and Region (ddlRegion). When Area selection is changed, Region items need to be updated accordingly. Both comboboxes have "EnableAutomaticLoadOnDemand" set to true. I have a java-script handler assigned to OnClientSelectedIndexChanged of ddlArea combobox to avoid post back, because this is all done is a "colorbox" modal window, which needs to be reopened after each post-back.

function requestData(sender, eventArgs) {

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

ddlRegion.requestItems(sender.get_value(), false);

}

On the server side, in ItemsRequested handler I'm able to determine which value has been selected by processing "Text" property. of event arguments. However, with automatic LoadOnDemand feature enabled, binding needs to occur also on every post back, inside Page_Load method. But when I set a breakpoint inside Page_Load, I see that ddlArea.SelectedValue has it's old value and not the one that was just selected. ddlArea.SelectedValue becomes updated only after post-back from a button for example.

Could you please advise what's the best solution for my problem would be?
Thank you!

FIX: Clicking the date header in week view results in a server-side exception

The exception is "FormatException: String was not recognized as a valid DateTime"

The issue is fixed in build 2010.1.526 and later. A workaround is to include the following script below the ScriptManager/RadScriptManager instance on the page:

<script type="text/javascript">

Telerik.Web.UI.RadScheduler.prototype._onDateHeaderClick = function (e)

{

$telerik.cancelRawEvent(e);

var date = new Date();

// Date headers have an href in the format #yyyy-MM-dd

var dateMatch = e.eventMapTarget.href.match(/#(\d{4}-\d{2}-\d{2})/);

if (dateMatch && dateMatch.length == 2)

{

var parts = $telerik.$.map(dateMatch[1].split("-"), function (part) { return parseInt(part, 10); });

date = new Date(parts[0], parts[1] - 1, parts[2]);

}
