Client-side RadComboBox Creation

Hello,

I've seen in other forum posts that creating a RadComboBox dynamically in client-side JavaScript is not possible. However, these posts are a couple of years old.

Has this changed? Does the latest version of Telerik controls support dynamic creation of RadComboBoxes in client-side JavaScript?

Thanks,
Greg

RadTabStrips and FancyBox

Hi,

I am creating a page which is based on the example called Load on Demand RadPageView of the TabStrip in Telerik's examples app.

The code behind for the default page is:

protected void Page_Load(object sender, EventArgs e)

{

if (!Page.IsPostBack)

{

AddTab("Home");

AddPageView(DaveRadTabStrip.FindTabByText("Home"));

AddTab("Apps");

AddTab("Contact");

}

private void AddTab(string tabName)

{

RadTab tab = new RadTab();

tab.Text = tabName;

this.DaveRadTabStrip.Tabs.Add(tab);

}

protected void DaveRadMultiPage_PageViewCreated(object sender, RadMultiPageEventArgs e)

{

string userControlName = @"~/UserControls/" + e.PageView.ID + ".ascx";

Control userControl = Page.LoadControl(userControlName);

userControl.ID = e.PageView.ID + "_userControl";

e.PageView.Controls.Add(userControl);

}

private void AddPageView(RadTab tab)

{

RadPageView pageView = new RadPageView();

pageView.ID = tab.Text;

DaveRadMultiPage.PageViews.Add(pageView);

tab.PageViewID = pageView.ID;

}

protected void DaveRadTabStrip_TabClick(object sender, RadTabStripEventArgs e)

{

AddPageView(e.Tab);

e.Tab.PageView.Selected = true;

}

The apps user control (for the Apps tab) has a TabStrip on it. So, I have tabs inside of a tab.

There is a javascript function which is not working. On the tabs on the Apps user control, there are some hyperlinks which load a image into a "lightbox" using a jScript plugin called FancyBox. That plugin is not working. I recognise that Telerik makes no guarantee that its controls do not work with 3rd party controls (and fair enough). But I wanted a LightBox and Telerik does not have one (RadWindow comes close, but at the end of the day, that is not its purpose - and there's no elegant animation with RadWindow either).

Here is the markup for that user control:

<%@ Control Language="C#" AutoEventWireup="true" CodeFile="Apps.ascx.cs" Inherits="UserControls_Apps" %>

<div id="contentOnPage">

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

<script type="text/javascript" src='<%=Page.ResolveClientUrl("~/js/jquery.fancybox-1.3.1.js") %>'></script>

<script type="text/javascript">

$(document).ready(function () {

$("a.lib").fancybox({

'transitionIdn': 'fade',

'transitionOut': 'fade'

});

</script>

</telerik:RadCodeBlock>

I really want to get to the bottom of this, to develop a better understanding of working with tabs, and AJAX and javascript and how they can all play well together. I need this skill for my job, where I develop enterprise apps using these tools. I'm happy to provide the whole VS solution if that helps (it is not that big, as I am just using it to learn concepts).

Thanks

Edit - further info. I have found that Fancybox will work without AJAX on the tabs. When I add the following AJAX, the FancyBox does not work:

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

<AjaxSettings>

<telerik:AjaxSetting AjaxControlID="DaveRadTabStrip">

<UpdatedControls>

<telerik:AjaxUpdatedControl ControlID="DaveRadTabStrip" LoadingPanelID="DarRadAjaxLoadingPanel" />

<telerik:AjaxUpdatedControl ControlID="DaveRadMultiPage" LoadingPanelID="DarRadAjaxLoadingPanel" />

e.NewPageIndex Returns Invalid Values

I'm seeing some strangeness in e.NewPageIndex - occasionally, it is returning int.MaxValue.

The code I'm using is simplicity itself:

protected void gvApprovals_PageIndexChanged(object source, Telerik.Web.UI.GridPageChangedEventArgs e) {

user.Options.ApprovalGrid.CurrentPage.Value = e.NewPageIndex;

}

Is there any obvious reason why it would return int.MaxValue?

RadGrid Column Quesiton

I have a client you is wanting an internal messaging(or email like) system added to their product. The problem we are running into is sending messages to mutilble users(see screen shot). The last three messages were all sent as one message, is there any way to group these messages into one line using the radgrid without using the grouping already built into radgrid? Example: the sent to column would show a string of the the users names and the rad grid would show that message as one messge.

RadGrid Postback URL ReWrite

Hi,

I have a Radgrid with paging and sorting enabled on page that uses url rewrite.

My page is called http://mywebsite.com/mypage.aspx but use Helicon rewrite to display the page as http://mywebsite.com/DirName/mypage/

When I click on the page numbers I get 404 can I get around this. I've tried the seo friendly paging and that doesn't work either.

Thanks

RadGrid with User Control as Edit form

Hello,

I am using a RadGrid which is wrapped in a RadAjaxPanel.

This RadGrid contains a user control that we are using for the editing of grid data.

On the user control, I have several textboxes, a "Save" button and a "Cancel" button.

On the Save button, I have the OnClientClick set to OnClientClick = "return CanSave();". (I have also tried setting OnClientClick to OnClientClick="return true;" and OnClientClick = "if (CanSave()) return true;", all with the same results.)

CanSave() is a javascript procedure defined in the user control. My Javascript is wrapped in a RadScriptBlock.

CanSave() returns a TRUE if the Save should take place. I have verified that my "return true" line is being executed in this function.

Here is my problem:

When CanSave() returns true, no postback is happening. If I remove the RadGrid from the RadAjax panel, it works fine when I click "Save" and CanSave() runs and returns true. Or, if I leave the RadGrid in the RadAjax panel, and remove the OnClientClick event from the Save button and cilck the Save button, the PostBack occurs and everything works fine.

So, in short, having the RadGrid in a RadAjaxPanel and having the OnClientClick assigned to CanSave() on my user control that edits the data in the grid causes no Post Back to occur when clicking the Save button on my user control that edits the data in my RadGrid.

Any ideas as to what I might be doing wrong? Code is below.

Here is my RadGrid:
