Hi,

Is it possible to capture timeslot selection end event at client side? onClientTimeSlotClick event is fired whenever I click on a timeslot. Is there an event fired when user finishes selecting a range at client side? Or better OnClientTimeSlotSelecting and OnClientTimeSlotSelected events will be perfect.

TIA.

Loading images into PanelBar on page load

I have a page where I am using a RadPanelBar as a menu.

I want to kick off an ajax process when a page loads that does some database work and then changes an image on each item in the panelbar according to the results.

So far I have:

<telerik:RadCodeBlock runat="server">

<script type="text/javascript">

function pageLoad(sender, eventArgs) {

if (!eventArgs.get_isPartialLoad()) {

$find("<%= RadAjaxManager1.ClientID %>").ajaxRequest("InitialLoad");

}

</script>

</telerik:RadCodeBlock>

Which successfully kicks off my process when the page loads, so I'm good there.

The problem is that the images in the PanelBar never change.

My RadAjaxManager looks like so:

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

onajaxrequest="RadAjaxManager1_AjaxRequest">

<AjaxSettings>

<telerik:AjaxSetting AjaxControlID="pbMenu">

<UpdatedControls>

<telerik:AjaxUpdatedControl ControlID="pbMenu" />

</UpdatedControls>

</telerik:AjaxSetting>

</AjaxSettings>

</telerik:RadAjaxManager>

and the work code looks like:

protected void RadAjaxManager1_AjaxRequest(object sender, Telerik.Web.UI.AjaxRequestEventArgs e) {

if (e.Argument == "InitialLoad") {

RunLoadSim(pbMenu.Items);

}

private void RunLoadSim(RadPanelItemCollection items) {

foreach (RadPanelItem i in items) {

i.ImageUrl = "~/images/menublocks/grey.png";

RunLoadSim(i.Items);

var start = new ParameterizedThreadStart(Sim);

var thread = new Thread(start);

thread.Start(i);

}

private static void Sim(object arg) {

var r = new Random();

var i = r.Next(200, 5000);

Thread.Sleep(i);

var green = r.Next(0, 2) == 0;

var imgUrl = green ? "green" : "red";

((RadPanelItem) arg).ImageUrl = "~/Images/MenuBlocks/" + imgUrl + ".png";

}

The "work" code is just garbage to simulate db look ups right now.

Basically it sets the image in every panelbaritem to a grey square, then runs a fake worker process that sits for .2 to 5.0 seconds then loads either a green or red image in place of the grey one.

None of the colored squares ever appear though.

What am I doing wrong?

Thanks.

RadSplitter and RadSplitBar are not work in masterpage

Hi

I use RadSplitter, RadPane and RadSplitBar in masterpage in asp.net but I can't resize or collapse RadPane.

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

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

</asp:Content>

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

<p></p>

<script type="text/javascript" language="javascript">

</script>

<asp:ScriptManager ID="ScriptManager1" runat="server">

</asp:ScriptManager>

<telerik:RadSplitter ID="RadSplitter1" runat="server" Skin="Vista" Width="100%" Height="550px">

<telerik:RadPane ID="LeftPane" runat="server" Width="350" MinWidth="200">

left panel

</telerik:RadPane>

<telerik:RadSplitBar ID="RadSplitBar1" runat="server" CollapseMode="Forward"/>

<telerik:RadPane ID="RightPane" runat="server" Scrolling="None" OnclientResized="afterResize">

right panel

</telerik:RadPane>

</telerik:RadSplitter>

</asp:Content>

If I use them in project without masterpage then it work fine.

Can you help me to solve it.

Thanks.

Radconfirm add from CodeBehind

Hi Everyone,

I have a scenario where I would like to use a Radconfirm but only if some server side validation warrants it.
I am using a RadAjaxManager on a Masterpage. I am using RadAjaxManagerProxy on the Page.

Scenario:
I have a Textbox and a Save RadButton.

- Click Save Button
     < Server side check of Database to see if name already exists >

          1) Name already exists - Radconfirm will appear
               - Yes - Perform Save
               - No - close Confirm message

          2) Name does not exist
   - Perform Save

Any suggestions on how to achieve this would be much appreciated.

Thanks

Bran

I am using RadAjax panel for the whole page. I am having listboxes and other labels in my page along with radgrid.

When I move listitem from one listbox to another listbox, I am using radajax panel not to postback.

But after that I see the columns in the RagGrid, 2 of them are disappearing which I am displaying Dynamically.

All other columns are bound columns. What is the reason ?

export to csv issue

I have a radgid that has a button for each export. (csv,xls,word,pdf) They are all set up the same and they all work except for the csv one. The CSV is only exporting the headers not the data. It used to work and nothing has changed that has anything to do with the export but now it is not working. I have tried the following steps. Rebooted my machine and restarted VS and i have also rerefrenced Telerik.Web.UI.dll and it is still only giving me "MenuId","MenuPageKey","MenuHeader","MenuLinkText","MenuLink","MenuSortOrder","MenuView","MenuHeaderSortOrder"

PDF word and excel all give me full data

below is my radgrid code and the code for the exports.
