Cannot read property 'attributes' of null

Hi,

I'm using RadGrid and when I select (one click) one row I got javascript error on line :

"var l=e.attributes;"

The page to replicate the error: http://glidetours.pt/holiday/cart?ActivityID=12209 (cliking on any radiobutton we got same error)

Any one have any clue on how to fix this?

Image for Selected Item

Hi,
Is there a way to show the selected Item's image in the RadComboBox or RadDropDownList? I have items that are only images with no text. When the item is selected nothing shows in the combo box. Is there a way to display the selected item's image?

Thanks

Select text although AllowRowSelect is true

When i set AllowRowSelect as True within the ClientSettings i am not able to select the content of the rows anymore.
For instance, if i want to select the title and description text i am unable. Is it possible to keep the client-side selection as is but still being able to select the content in sense of COPY operation?

Thanks

RTF <-> HTML for editor loses bullet list

I have the following rich text string set in a microsoft rich text box in a winforms app ... simple bulleted list of 2 lines.

{\rtf1\fbidis\ansi\ansicpg1252\deff0\deflang1033{\fonttbl{\f0\fnil\fcharset0 Calibri;}{\f1\fnil\fcharset0 Verdana;}{\f2\fnil\fcharset2 Symbol;}}

\viewkind4\uc1\pard{\pntext\f2\'B7\tab}{\*\pn\pnlvlblt\pnf2\pnindent0{\pntxtb\'B7}}\ltrpar\sl240\slmult1\f0\fs18 bullet item 1\f1\fs20

\par \f0\fs18{\pntext\f2\'B7\tab}bullet item 2\f1\fs20

\par }

I run that through this formatting process:

//convert from RTF to HTML

RtfFormatProvider rtfProvider = new RtfFormatProvider();

HtmlFormatProvider htmlProvider = new HtmlFormatProvider();

RadFlowDocument document = rtfProvider.Import(richText);

RadEditorRichTextLabNote.Content = htmlProvider.Export(document);

I end up with the two lines of text but the bulleted part is gone.

Going from HTML back to RTF also loses the bulleted list.

See the screenshots below of how the winforms application shows the rich text vs the asp.net radeditor.

Please advise. Thanks

AsyncUpload Validation

I am trying to get some validation done. When a user selects the wrong file type I can see the red dot beside the file but when I click submit the postback happens anyway regardless if the file is an Xlsx or not.

I would like to display an error message without postback as the asp.net built in validation can do.

See below for test code:

<telerik:RadAsyncUpload ID="RadAsyncUpload1" runat="server" AllowedFileExtensions="Xlsx" MultipleFileSelection="Disabled" ValidateRequestMode="Enabled" ValidationGroup="TEST" MaxFileInputsCount="1">
</telerik:RadAsyncUpload>
<telerik:RadButton ID="RadButton1" runat="server" Text="Submit" ValidationGroup="TEST" OnClick="RadButton1_Click"></telerik:RadButton>
<asp:ValidationSummary runat="server" DisplayMode="BulletList" ShowSummary="true" ShowValidationErrors="true" ShowMessageBox="true" ValidationGroup="TEST" />

RadConfirm Always returning False

Hi,

I'm using RadConfirm and initiating it from a C# method. The confirm window pops up just fine, but in my JavaScript is always returning false. Here is an example of what I have:

C#

protected void txtUserName_DupValidator_ServerValidate(object source, ServerValidateEventArgs args)

{

if (hfUserName.Value != txtUserName.TextWithPromptAndLiterals)

{

if (!(Controller).IsUsernameUnique(txtUserName.TextWithPromptAndLiterals))

{

args.IsValid = false;

rwmDialogs.RadConfirm("This is an existing user, do you want to edit the existing user or cancel?", "confirmCallBackFn", 300, 250, null, "Verify User");

}

JavaScript

function confirmCallBackFn(arg) {

//radalert("<strong>radconfirm</strong> returned the following result: <h3 style='color: #ff0000;'>" + arg + "</h3>", 350, 250, "Result");

if (arg = "false") {

newWindow = openAdminPage("../../../Users");

return false;

}

else {

PageMethods.DisplayUser(document.getElementById("<%=txtUserName%>".value))

}

Markup

<telerik:RadWindowManager ID="rwmDialogs" runat="server" RenderMode="Lightweight" EnableShadow="true"></telerik:RadWindowManager>

DisplayNavigationButtons doesn't work from declaration

Setting the DisplayNavigationButtons property to false in the Wizard declaration doesn't appear to work. Setting it server-side does. I am using version 2016.1.113.40

this.MasterTableView.Columns.Clear() does not clear the private variable this.viewStateNotManagedCount

It can be reproduced by creating some columns, then clear and then add less columns that the initial numbers of columns.

Then the control throws an exception in SaveViewState saying the index is out of range.

RadUpload not working in MS edge

Hi,

We are using Rad Update control with Rad progress for uploading documents in one of the UIs of our website. This functionality works fine with IE 5.5 version and above but the files are not uploaded in Chrome and MS Edge browser. Browsed through this page http://docs.telerik.com/devtools/aspnet-ajax/controls/upload/overview and got know the Chrome is not listed in the supported browser list. However, MS Edge is a new release and I am curios to know if these controls are supported in edge or not?

Right now, the functionality is not working and it will be great if we get some pointers related to work-around for this kind of a challenge faced in MS edge browser and alternatives that can be used to make the page that is using Telerik upload control compatible with both IE and MS Edge.

Thanks in advance,

Kishan
