I've implemented StripFormattingOptions and StripFormattingOnPaste (set to AllExceptNewLines) to strip formatting and OnClientPasteHTML to display an alert to the user that the formatting is being stripped from the pasted text. This works fine in IE and Firefox, but in Chrome and Safari the OnClientPasteHTML also fires when the user hits the Enter key while in the Rad Editor.

Has anybody else seen this behavior and what can I do to resolve it (other than removing the alert)?

Client Event Listener OnBatchEditCellValueChanged

From what I can tell OnBatchEditCellValueChanged triggers on blur of the field. Am I correct in this assumption?

Facebook Social Sharing Button

I am using the following code in my template to show social share buttons for FB, Twitter and LinkedIn. A peculiar thing I am noticing is that the FB button doesn't always show and I am not observing any pattern for when it appears or hides.

<telerik:RadSocialShare ID="SocialShare" runat="server">

<MainButtons>

<telerik:RadFacebookButton />

<telerik:RadTwitterButton />

<telerik:RadLinkedInButton />

</MainButtons>

</telerik:RadSocialShare>

Has anyone else noticed this behaviour and found a solution?

Rad menu using Mobile hamburger

The open sub menu function only works when the >
image is selected, not anywhere in the item (as would be expected)

But when going back the user can select any area in
the menu item and it will go back correctly (as you would expected)

It has been like this for some years or am I doing something wrong?

Removing the Add New Item button on Detail Tables

Hi

I am trying to make my radgrid (which is wrapped in a usercontrol) "readonly".
For this I need to remove the "Add New Record" button and the "Edit" and "Delete" columns of the grid.
I have got the following code to work where the "Edit" and "Delete" columns get removed for the master as well as all the detail tables (I have 4 levels of details), but when it comes to removing the "Add New Record" from the command item bar only the button on the MasterTable gets removed. Any ideas what I am missing here or how I could hide the button on detail tables?

protected override void OnPreRender(EventArgs e)

{

//Complete normal prerender stuff.

base.OnPreRender(e);

if (ReadOnly)

{

MakeGridReadOnly(MasterTableView);

}

private static void MakeGridReadOnly(GridTableView radGridTableView)

{

HideAddNewCommandButton(radGridTableView);

HideEditDeleteColumns(radGridTableView);

foreach (var detailView in radGridTableView.DetailTables )

{

MakeGridReadOnly(detailView);

}

private static void HideAddNewCommandButton(GridTableView radGridTableView)

{

/* http://www.telerik.com/community/forums/aspnet-ajax/ajax/radgrid-addnewrecordbutton-problem-on-prerender-event.aspx#2169542*/

if (radGridTableView.GetItems(GridItemType.CommandItem).Length <= 0) return;

var commandItem = radGridTableView.GetItems(GridItemType.CommandItem)[0];

var newRecordButton = commandItem.FindControl("AddNewRecordButton");

if (newRecordButton != null) newRecordButton.Visible = false;

var initInsertButton = commandItem.FindControl("InitInsertButton");

if (initInsertButton != null) initInsertButton.Visible = false;

}

private static void HideEditDeleteColumns(GridTableView radGridTableView)

{

try

{

GridColumn editColumn = radGridTableView.Columns.FindByUniqueName("EditCommandColumn");

if (editColumn != null)

editColumn.Visible = false;

}

catch

{

}

try

{

GridColumn deleteColumn = radGridTableView.Columns.FindByUniqueName("DeleteCommandColumn");

if (deleteColumn != null)

deleteColumn.Visible = false;

}

catch

{

}

Batch edit refreshing datasource before perform the update

Currently I am working with a RadGrid that is using batch update that is attached to a SqlDataSoure to load, update and delete. Everything is working fine but normally the users spend around 20 minutes to review and update everything they need before hit "Save Changes", during this process new records are inserted in the database so the data displayed on the screen is not the same of the database. When the user finally hit "Save Changes" the grid refresh first the dataset and after that perform the updates generating errors because records that were not displayed are updated.

Is there a way to tell the grid to load the data only when it is not postback? Like doing it in the OnNeedDatasource in the code behind.

Getting Started - Problems

I've recently converted an ASP.NET 2.0 application to 3.5 and have been trying to add telerik.

vs2013 & Telerik asp.net ajax v2015.1.401.35

Recently converted an ASP.NET 2.0 web application to 3.5 and it runs fine.

I've used the telerik wizard to add the necessary bits to web.config.

Tried replacing the scriptmanager with RadScriptManager, but that errors with

JavaScript critical error at line 4, column 1 in http://localhost/iWebTest/Telerik.Web.UI.WebResource.axd?_TSM_HiddenField_=ctl00_ScriptManager1_TSM&compress=1&_TSM_CombinedScripts_=;;System.Web.Extensions,+Version=3.5.0.0,+Culture=neutral,+PublicKeyToken=31bf3856ad364e35:en-US:eb198dbd-2212-44f6-bb15-882bde414f00:ea597d4b:b25378d2;Telerik.Web.UI:en-US:bfbc94e0-0f9b-4d52-9983-75ffc518eea7:16e4e7cd:f7645509:22a6274a\n\nSCRIPT1002: Syntax error

so reverted to normal scriptmanager for now until that can be resolved.

Created a new web form, added a radtextbox and a button then in click event in the code behind I tried to retrieve the textbox.text value.. it just returns the original value, not the changed one..

What the heck have I done wrong ?

Major performance decrease in 2015 Q1

Hi,

We use the RadGauge a lot, but lately we had some real performance issues, mostly on tablets (iPad)!

When reverting back to a telerik version prior to 2015 Q1 (2014 something), all issues are gone...

In a simple example:

<%@ Page Language="vb" AutoEventWireup="false" CodeBehind="gauge.aspx.vb" Inherits="TestaTredjepartWeb.gauge" %>

<!DOCTYPE html>

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

<head runat="server">

<title></title>

</head>

<body>

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

<script type="text/javascript">

window.__dt = new Date();

setTimeout(function () { alert((new Date()) - window.__dt - 10); }, 10);

</script>

<asp:ScriptManager ID="s" runat="server">

</asp:ScriptManager>

<div>

<asp:Button ID="btn" runat="server" />

<telerik:RadRadialGauge ID="rrg" runat="server" Transitions="false">

<Pointer Value="44" Color="Red" Cap-Color="Yellow"></Pointer>

<Scale>

<Labels Position="Outside" Color="Gray" Font="normal 10px Segoe UI, Tahoma, Helvetica" />

<Ranges>

<telerik:GaugeRange From="0" To="40" Color="Red" />

<telerik:GaugeRange From="40" To="90" Color="Yellow" />

<telerik:GaugeRange From="90" To="200" Color="Green" />

</Ranges>

</Scale>

</telerik:RadRadialGauge>

</div>

</form>

</body>

</html>

When running this sample on a desktop computer, the alert says about 30ms with 2014 version and 100ms with any 2015 version, on an iPad it says 150ms with 2014 version and 600ms with any 2015 version.

About 3-4 times slower!

On some pages we have multiple gauges, which makes it even worse...
The 2015 Q2 Beta is also slow...

Regards
Andreas
