Load on Demand PageViewCreated not called

Hi,

sorry to create another Load On Demand post but it seems I cant find my issue in the previous ones Ive searched in. In my case, when trying to implement Load On Demand on my RadTabStrip, Ive noticed a weird behavior in the code.

When clicking on the tabs in the order they are presented and I skip one, then when I click on that skipped tab, its RadMultiPage's PageViewCreated dont get called. By looking at the tab's OnClientTabSelecting client-side function, it seems the tab already has a pageview assigned and it's id is the same then the tab we click when doing the skipping.

Here's the code to replicate the problem with 4 tabs:

<%@ Page Language="C#" AutoEventWireup="True" Inherits="PL.Test" Codebehind="Test.aspx.cs" %>

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

<head id="Head1" runat="server">

<title></title>

</head>

<body>

<telerik:RadCodeBlock ID="RadCodeBlock1" runat="server">

<script type="text/javascript">

function onTabSelecting(sender, args) {

if (args.get_tab().get_pageView()) {

if (args.get_tab().get_pageView().get_id()) {

alert("pageview of ID: " + args.get_tab().get_pageView().get_id() + " already loaded");

args.get_tab().set_postBack(false);

}

</script>

</telerik:RadCodeBlock>

AddNewTab(3);

AddNewTab(4);

RadTabStrip1.DataBind();

}

private void AddNewTab(int intTabIndex)

{

RadTab rootTab = null;

RadPageView pv = null;

rootTab = new RadTab();

RadTabStrip1.Tabs.Add(rootTab);

rootTab.Text = "Tab" + " " + intTabIndex.ToString();

rootTab.Value = "Tab_" + intTabIndex.ToString();

if (intTabIndex == 1)

{

pv = new RadPageView();

pv.ID = rootTab.Value;

RadMultiPage1.PageViews.Add(pv);

RadTabStrip1.Tabs[RadTabStrip1.Tabs.Count - 1].Selected = true;

RadMultiPage1.PageViews[RadMultiPage1.PageViews.Count - 1].Selected = true;

}

protected void RadMultiPage1_PageViewCreated(object sender, RadMultiPageEventArgs e)

{

Console.WriteLine(e.PageView.ID);

}

protected void RadTabStrip1_TabClick(object sender, RadTabStripEventArgs e)

{

AddPageView(e.Tab);

e.Tab.PageView.Selected = true;

}

private void AddPageView(RadTab tab)

{

RadPageView pv = new RadPageView();

pv.ID = tab.Value;

RadMultiPage1.PageViews.Add(pv);

tab.PageViewID = pv.ID;

}

Page will start and create Tab 1. If you click on Tab 3 then Tab 2, you'll notice that Tab 2 pageview ID is already known and that "RadMultiPage1_PageViewCreated" doesnt get called. Same if you refresh and click Tab 2, then Tab 4 and then Tab 3. If you go 2, 3 and 4, all is fine. Is something wrong in my code?

TIA

Needs to remove the space of chartarea in RadChart control and display only the plot area

Hi,

We have requirement to display the RadChart control with plotarea only in one of the column of a Radgrid control. when implemented this requirement, we found that displays the empty space of chartarea, plot area. so the radchart control is not adapted to the column of a grid.
When tried to remove this empty space, (as mentioned in one of the forum, AutoLayout property set to false) it removes only the empty space of plot area. but it does not remove the empty space of chartarea (like title, xaxis, yaxis, legend) even if those visibility is set to false.

please assist to achieve this.

Regards,
Meenakshi

Ajax and combo

I am having strange results with the combo box. For some reason it is rebindig after I bind it.

My first issue was u was trying to remove an item from the list if it was not selected. Since it was doing this word reminding, I had to remove it on the ondataload method. The next problem was that the selected value was not remaining. I set the value. I step through the code and I see it being set. Then when the page is displayed the value is no longer set. How can I track these behind the scenes processes.

Set RadGrid TabIndex=-1

I am trying to prevent a tab stop on an entire RadGrid control, but I have not been able to accomplish this. I have tried setting the TabIndex property equal to -1 and also tried surrounding the grid with a panel with a TabIndex of -1. Neither of these attempts were successful.
Can anyone provide any assistance with this issue?

Intermittent failure of captcha image to appear

Hi there

I have a consistent but intermittent (maybe 50:50) problem with the image for a radCaptcha control not being displayed, showing instead only the grey box on the occasions that the rendering fails. I know about using the HttpHandlerUrl property to explicitly provide the location of Telerik.Web.UI.axd, and the fact that the image is loaded from the Cache by default, so I am wondering if this is some issue with a cache management conflict caused by some other javascript functions I am running on page load?

Could anybody point me in a good direction about how to troubleshoot this issue, as I have run out of ideas! Is there any client-side API for radCaptcha that might allow me to examine what is going on with the captcha control as the client side script runs? Failing that, is there a recommended location for setting the HttpHandlerUrl property back at the server-side processing? I have tried the init handlers for both the page and the control itself, but nothing makes any difference to the problem.

Thanks if you can advise
