RadTreeView context menu not working in Chrome

I am using VS.Net 2010. I have a RadTreeView control that has a RadTreeViewContextMenu. The RadTreeView control is defined in a User Control. This user control is used in a ASP.Net form inside of a modal popup window.

When the form is run and the modal popup is displayed, the context menu displays as expected when a node is right clicked. This works fine in IE, and FireFox.

The problem we are having is that the context menu is NOT displaying in Chrome under the above circumstances.

However, without the modal popup, the context menu does display.

Why won't the context menu display in Chrome with the control inside of a modal popup?

RadButton's OnClick event not fired when inside MasterPage

Hello,

I have been stuck on this weird bug where RadButton's OnClick event is not fired when the control is inside my MasterPage.

This example does not work

...

<form runat="server">

<telerik:RadScriptManager runat="server" ID="_scriptManager"/>

<telerik:RadAjaxManager runat="server" ID="_ajaxManager" RequestQueueSize="100" EnableTheming="true" />

<telerik:RadFormDecorator runat="server" ID="_formDecorator" Skin="Metro" DecoratedControls="All" EnableAjaxSkinRendering="true" />

<telerik:RadSkinManager runat="server" ID="_skinManager" Skin="Metro" />

<div id="wrap">

<div id="header">

<div id="logo">

<img src="" width="200px"/>

</div>

<table id="Table1" style="width:100%" runat="server">

<tr>

<td style="float:left;">

</td>

<td style="float:right;">

<telerik:RadButton ID="RadButton1" runat="server" Text="text" OnClick="Unnamed_Click" />

<%--<userControl:AuthenticationUC runat="server"/>--%>

</td>

</tr>

</table>

</div>

<div id="main">

<asp:ContentPlaceHolder runat="server" ID="MainContent"></asp:ContentPlaceHolder>

</div>

<div id="footer">

<div> © <%: DateTime.Now.Year %> - Antoine Cloutier </div>

</div>

</form>

...

But this one does work:

<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="WebForm1.aspx.cs" Inherits="AntoineCloutierWebApp.WebForm1" %>

<!DOCTYPE html>

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

<head runat="server">

<title></title>

</head>

<body>

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

<div>

<telerik:RadScriptManager runat="server" />

<telerik:RadButton runat="server" Text="text" OnClick="Unnamed_Click" />

</div>

</form>

</body>

</html>

Note: I am using 2013.3.1015.45 RadControls for ASP.NET Ajax.

Thanks!

Hierarchy Grid Last Row

Hi there.

How do I iterate through a Hierarchial Table and find the last row? Ive done this at the top level without DetailTables - OnPreRender I can go grab the Last GridItem and find the appropriate control and set the visibility. Thanks.

So something like -

if (rgQuestions.Items.Count > 0)

{

GridItem gi = rgQuestions.Items[rgQuestions.Items.Count - 1];

ImageButton btnDown = gi.FindControl("btnDown") as ImageButton;

btnDown.Visible = false;

}

Error Rendering Control - Designtime

I have a ASP.NET site which we are upgrading from .net framework 3.5 to 4.0 and everything seems to be working fine. I also upgraded from telerik dll from 2010.2.929.20 to 2011.1.315.40.

The only problem that I am having is the telerik controls placed in User Control which then placed on aspx page is not rendering in Visual Studio 2010. The user controls is displayed as error -

System.NotSupportedException:Specified method is not supported at System.Web.UI.Design.UserControlDesign.Dummy.RootDesigner.DummyWebFormsReferenceManager.RegisterTahPrefix(Type objectType) at ....(please see complete error in attached file)

I removed the old reference of telerik dlls and added them back again with the new dll..

Versions :
- Visual Studio 2010 Professional
- Telerik Control - 2011.1.315.40
- .net framework 4.0

Please advise.

Thanks.

[Solved] Legend Appearance and series item Position

2. Chart series labeltext values are overlapping. I want to keep the labeltext value at the end of series item. I have marked in the attached image.

Drag'n'drop from ListView to singlebinded OrgChart

Hello there.

I have been trying to create an organization chart very similar to the "Transfer Employee"-example, but ran into a little problem, cause I needed to change it from a grouped binding to a single binding.

I played around with the OnClientDropping-function, but can't really twist it to fit my perpose.

When I drag an element from the listview, to an element in the OrgChart, it should make the new element a child of the element dropped on, and the ajax-update i working like a charm, but the _getRealHierarchicalIndex seems to return 0 every time.

function OnClientDropping(sender, args) {

var orgChart = $find("<%= RadOrgChart1.ClientID %>");

var itemText = args.get_sourceItem().get_text().trim();

if (args.get_htmlElement().className.indexOf("rocItem") != -1 || $(args.get_htmlElement()).parents(".rocItem").length > 0) {

var hierarchicalIndex = orgChart._extractNodeFromDomElement(args.get_htmlElement())._getHierarchicalIndex();

hierarchicalIndex = orgChart._getRealHierarchicalIndex(hierarchicalIndex); //gets right index if drill down is on

$find("<%= RadAjaxManager2.ClientID %>").ajaxRequest("drop-" + itemText + "-" + hierarchicalIndex);

}

dropClue.style.display = "none";

noDropClue.style.display = "none";

}

As you can see, I have only changed the rocGroup to a rocItem, and ofcause it gives me some problems in the RadAjaxManager2_AjaxRequest, cause the ids contains ether 0 or 0:0

Here's the start of the AjaxRequest:

char[] seps = { '-' };

string[] textAndIds = e.Argument.Split(seps, StringSplitOptions.None);

char[] sep = { ':' };

string[] stringIds = textAndIds[2].Split(sep, StringSplitOptions.RemoveEmptyEntries);

int[] ids = new int[stringIds.Length];

for (int i = 0; i < stringIds.Length; i++)

{

ids[i] = Int32.Parse(stringIds[i]);

}

if (textAndIds[0] == "drop")

{

string newText = textAndIds[1];

OrgChartNode node = RadOrgChart1.GetNodeByHierarchicalIndex(ids);

var rows = from myRow in initialeEmployees.AsEnumerable() where myRow.Field<string>("FullName") == newText select new { values = myRow };

string imageUrl = "";

string emloyeeId = "";

foreach (var row in rows)

{

imageUrl = row.values.Field<string>("ImageUrl");

emloyeeId = row.values.Field<string>("EmployeeID");

break;

}

employees.Rows.Add(new string[] { emloyeeId, node.ID, newText, imageUrl });

}

Problems with Chrome and FireFox

When uploading a zero byte file neither Chrome nor FireFox send the file to the server. IE sends the file where my upload handler assess the size and sends the error message back correctly. I've seen other posts on the forum that have similar issues with FF and Chrome but there never are any solutions (in fact one seems to be exactly the same problem I am having but no solution). Is there some configuration setting that I can set to make this work?

I'm using version 2011.3.1115.40.
