Window close delay

Hi,
I am using a radwindow, and load an .aspx page in it. The only allowed behaviour of the window is the closing. The page that is loaded in the window has a listview control, and two grids. When i press the close button on the window titlebar, the window does not close immediately, which is the desired behaviour, but it takes a few seconds. How can I decrease that delay?

Thanks a lot,
Angie

TimeSlot selection end

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
