Hi,

I found an error when you have empty your Editor and push backspace, I was using this example: https://demos.telerik.com/aspnet-ajax/editor/examples/contentareamodediv/defaultcs.aspx and look this video https://www.screencast.com/t/5qZe3e2IJxti  where I replicate the scenario with the javascript error. 

I have a simple RadGrid with 2 columns. I have set AllowGenerateColumns to false but I am using the NeedData Source to populate the Grid.   One column is a Text box and the other is a dropdown list.  I have nor problems showing the Grid with the data and I can add new records.
Here is my ASPX code to for this Grid:

And Here is my Code behind

I can retrieve the selected value of the DropDownList but when the code line to set the value of the strContact runs I get an unhandled exception. "JavaScript runtime error: ObjectReference not set to an instance of an object.
When I inspect the TextBox txtContacts it does not show a web control it shows as null.

Any one have any ideas as to why this web control is not being found?

Hi

I have seen this post : https://www.telerik.com/forums/error-script-controls-may-not-be-registered-before-prerender

But it seems i can't solve the problem...

I have to integrate TELERIK AJAX composant in an old project (Visual Studio 2010 / ASP.Net )

I understood that RadScriptManagerraise an error : Script controls may not be registered before PreRender

But i don't understand what i have to do.

Hello,

I have a grid with automatic insert and update operations. Just before data was recording in database, i woult like modify them. In this case, i have 0130 in "Durée" field of my insert form, and i want to record 01:30 in database (see RadGridTemps_InsertCommand in the cs file below)

Is it possible?

     I have Filter by Columns turned on in RadGrid, and the UI displays the text input boxes and filter button. But clicking the filter button doesn't show the filter menu, and the JS console is showing an error: $find is not defined. I'm guessing I'm missing a JavaScript library. This is an inherited app that I'm trying to repair, so if there's any guidance as to which script files I need or how to pull them in through an installer, it would be greatly appreciated.

<telerik:radgrid runat="server" ID="rgConfirmed" AllowFilteringByColumn="True" AllowPaging="True" AllowSorting="True" ShowStatusBar="True"
                        DataSourceID="DropShipOrders" GridLines="None"  PageSize="20" Skin="Telerik" AutoGenerateColumns="False">

function OnClientBeforeShow(sender, args) {      
    setTimeout(function () {         
       var active = Telerik.Web.UI.RadToolTip.getCurrent();         
       var browserWidth = $telerik.$(window).width();         
       var browserHeight = $telerik.$(window).height();        
       var width = (Math.ceil(browserWidth * 50 / 100));         
       active.set_width(width);         
       active.get_popupElement().style.width = width + "px";     
   }, 0); 
}

I have used this above mentioned script for RadToolTipManager control in "OnClientBeforeShow" event, it working fine for 1366x768 resolution but if i change the resolution, it is breaking. I need to have dynamic tooltip which will resize according to data it is populated. And please suggest how to adjust font size of text in a tooltip.

Is there a way to control how much space is between lines with checkboxes on them? I have a form with several checkboxes, and I'd like to reduce how much whitespace is between the lines. Each line is terminated with a <br />.

When I generate pdf from  , it generates SECURED pdf by default. So when I check the security of the pdf, it says Security Method = Password .

Below are my export settings:

 <telerik:RadEditor ID="dummyradEditorExport" ContentFilters="DefaultFilters,PdfExportFilter"  ExportSettings-Pdf-UserPassword=""
                                        Height="500" Skin="Default" Width="685" runat="server" ImageManager-EnableImageEditor="true" NewLineMode="Div">
                                        <ExportSettings FileName="ExporttoPDF" OpenInNewWindow="true" Pdf-PageBottomMargin="1.0 cm"
                                            Pdf-PageLeftMargin="1.5 cm" Pdf-PageRightMargin="1.5 cm" Pdf-PageTopMargin="1.0 cm" 
                                             Pdf-AllowCopy="true" Pdf-AllowPrinting="true" Pdf-AllowModify="true" >
                                        </ExportSettings>

Please suggest why its doing this because my users are not able to open this pdf on iOS and Edge.
