[Solved] Cancel javascript event not working for Firefox

Hello. I have just written a lovey new web client using Telerik and was moments away for releasing it, when during browser testing I found that Firefox was not working as expected. As a result, all my many hours of hard work are going to waste.

When using the RadButton, I sometimes call a javascript method to do some client side validation before allowing the postback. I can not stop Firefox from posting back ;-( I've made an example:

using Telerik.Web.UI;

public partial class Default : System.Web.UI.Page

{

protected void Page_Load(object sender, EventArgs e)

{

if(this.IsPostBack)

{

radWindowManger.RadAlert("I dont want to see this Post Back", null, null, "Firefox HATES You", null);

}

protected void btnGo_Click(object sender, EventArgs e)

{

bool stopHere = true;

radWindowManger.RadAlert("I don't want to see this server message", null, null, "Firefox Hates YOU!", null);

}

<html xmlns="http://www.w3.org/1999/xhtml">

<head runat="server">

<title></title>

<telerik:RadStyleSheetManager id="RadStyleSheetManager1" runat="server" />

<script type="text/javascript">

//Put your JavaScript code here.

function displayRadAlert(sender, eventArgs)

{

radalert("Hello World");

event.returnValue = false;

event.cancel = true;

if(event.stopPropagation)

{

event.stopPropagation();

}

</script>

</head>

<body>

<form id="form1" runat="server">

<telerik:RadScriptManager ID="RadScriptManager1" runat="server">

<Scripts>

<asp:ScriptReference Assembly="Telerik.Web.UI" Name="Telerik.Web.UI.Common.Core.js" />

<asp:ScriptReference Assembly="Telerik.Web.UI" Name="Telerik.Web.UI.Common.jQuery.js" />

<asp:ScriptReference Assembly="Telerik.Web.UI" Name="Telerik.Web.UI.Common.jQueryInclude.js" />

</Scripts>

</telerik:RadScriptManager>

<telerik:RadWindowManager ID="radWindowManger" runat="server" EnableShadow="true"/>

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

</telerik:RadAjaxManager>

<div>

<telerik:RadButton ID="btnGo" runat="server" Text="Go"

OnClientClicked="displayRadAlert" OnClick="btnGo_Click" />

</div>

</form>

</body>

</html>

Please help!

Thanks in advance,

DBContentProvider

I've applied the example DBContentProvider-Vb.zip (http://www.telerik.com/support/code-library/connect-radfileexplorer-or-radeditor-to-a-sql-databse) on my website and everything seems to work except that it is not possible to upload files with extension .docx .pptx .xlsx
But it goes well with .doc ppt .xls
And I get no error message or anything ...
Have tried to enter: RadFileExplorer1.Configuration.SearchPatterns = New String () {"*. *"}
Without success...

What am I doing wrong?

Scheduler non-responsive in IE10+

I have a RadScheduler on a number of pages and when it is being run under IE10 or IE11 without compatility set on, the control is not responding. The previous and next buttons do not respond.

If I turn on compatibility mode then the control works as expected, but the date headers shift out of alignment with the calendar view.

I am using 2013.3.1114.40 version of the Controls.

You can see the behaviour exhibited using the following URL:

RadGrid Only has One Column Editor for all Items in Grid

I'm using the RadGrid with in-grid, batch editing enabled. I have the edit columns automatically generated for the rad grid. If I have one item, and I edit all the fields, I can get these changes after hitting my "update" button on the screen by:

masterTableView.GetBatchColumnEditor(myColumn) as GridTextBoxColumnEditor.TextBoxControl;

I can do this for all of my cells. But when I have more than one item in my grid, this editor only reflects the changes to the most recently changed object. When looking throughout the masterTableView and the Edit manager, it seems there is only one of these editor controls for each column, not one for each cell. Reading online, it seems there should be one for every cell. Am I understanding this correctly, or is this a limitation of radgrid?

Ajaxifing ITemplate programmatically

Hello, I have successfully programmatically ajaxified many composite controls, using the following steps:

1. Inside MyCompositeControl.OnInit: subscribe to Page.PreRender event
2. Inside Page.PreRender event: call AddAjaxSetting on desired child controls

Good!

Now I have a problem because one of my child controls is a FormView and inside I have a ITemplate derived class with many controls.
I’m not able to ajaxify these controls inside ITemplate.
The problem comes from the page lifecycle, that is:

1. MyCompositeControl.OnInit
2. Page.PreRender
3. ITemplate.InstantiateIn

So, during Page.PreRender it’s too early to ajaxify ITemplate subcontrols, because they are not yet created.
But Ajaxifing them at the end of ITemplate.InstantiateIn throws a System.ArgumentNullException.
