We suspect a bug of Telerik controls:

 

Bug of Telerik: PageView.set_contentUrl(MyUrl) method - call MyUrl twice if RadTabStrip and RadMultiPage is inside RadAjaxPanel control. Firefox only.

Code: http://bit.ly/2NVbm8Z

It enter here two times: http://bit.ly/2NZ0cQH

 

If try it in chrome - request goes only one time.

If remove RadAjaxPanel - also request goes only one time.

 

Is it bug of your Controls?

Hi Telerik

I get this error when opening WebControl EditForm from a RadGridView. I am using latest version of Telerik. Just updated :)

 

Unhandled exception at line 6, column 47683 in http://localhost:50919/Telerik.Web.UI.WebResource.axd?_TSM_HiddenField_=ctl04_TSM&compress=1&_TSM_CombinedScripts_=;;System.Web.Extensions,+Version=4.0.0.0,+Culture=neutral,+PublicKeyToken=31bf3856ad364e35:en-US:22727c22-244c-4537-8243-3c42cc5b20e2:ea597d4b:b25378d2;Telerik.Web.UI,+Version=2019.3.917.45,+Culture=neutral,+PublicKeyToken=121fae78165ba3d4:en-US:db44bcd4-c2d1-4f62-8c45-5cfd41578a98:16e4e7cd:33715776:f7645509:24ee1bba:e330518b:2003d0b8:c128760b:88144a7a:1e771326:c8618e41:1a73651d:16d8629e:f46195d3:6b3f73b3:58366029:aa288e2d:b092aa46

Hi,

In mobile and tablet device is very difficult increase and decrease the size of columns of RadGrid, exist a specified method or a workaround for resize a grid ? 

Is possible increase border(left/right) of column for change it more easiest ?

The respons of my ticket in forum is that:

"Hi Giacomo,

I am afraid we currently do not have alternative ways for resizing the Grid column. However, I advise that you share your idea officially by creating a Feature Request in the Progress® Telerik® UI for ASP.NET AJAX Feedback Portal. There the request will have the potential to become popular. Items with higher priority will be processed earlier."

 

Best regards

A function that will return a thumbnail of the requested size and the page of a multipage pdf document.

I would like to suggest a new product for Telerik: a html5 document editor (so not a html editor) which can edit docx documents. Recently I stumbled on the new html5 document editor by Teamlab (see http://html5.teamlab.com/), which will get its first major release this summer. I think such a component would also be an excellent addition to the Telerik product line as well (and probably a nice competitive advantage), since you already have some experience with the SL RichTextBox. It's probably not an easy project, but in the many years I've been a Telerik customer, I've seen a number of amazing components been created, so please forgive me for the high expectations. Just to mention (and perhaps as extra fuel for your discussion with management ;-)), I would personally favour a new HTML5 based editor. The current ASP.NET AJAX RadEditor is great in what it does -> HTML editing. Docx editing is very different in my view, both feature-wise as in regards to user-experience. As you can see from the Teamlab editor, it for example includes pagination and printing. I think it uses a different method for rendering too, e.g. canvas/SVG for pixel-perfect rendering. Very important for users to have what they type and see displayed on the screen be exactly the same as what they print. Basically I'm suggesting a MS Word Light by Telerik, something I believe your current SL RichTextBox is as well.

We are current experiencing a whitescreen with Telerik UI Controls for asp.net Ajax in chrome browser when the zoom level is less than 100. We observed a white screen instead of the rendered controls within main content area of our masterpage. The masterpage has several sections, header, left, mainconten, right and footer sections all divided by RadSplitter/RadPane controls. I attached a sample solution and screenshots of the observed issue.

Step to Reproduce:

- Open solution in Visual Studio

- Run choosing Chrome Browser

- Resize browser to 90%

- Reload the page

Expected

Page is rendered

Observed

White screen in the main content area

See attached screenshots

Bootstrap popularity is growing each day, not just as a flexible grid system, but for it's skinning capabilieties as well. There are dozens of sites with both free and priced Bootstrap skins..
It would be nice to have a skin for rad controls wich maps straight to default Bootstrap classes.
So that just using the bootstrap skins (+ base Telerik controls skin) will also theme the rad controls and changing the Bootstrap themes of course changes the controls theming.

I guess that option to have a "straight" mapping of the rad controls to the bootstrap default classes so to be able to take advantage of bootstrap themes would be a great addition.

=====================
Updated by Telerik admin on 10.4.2017:
The status of this highly demanded feature has been updated to Declined, but you can find details what has been done during the years for satisfying this request:

Since the markup of the controls does not offer direct mapping for the Bootstrap v3 and v4 themes and classes, we introduced a new Bootstrap skin for the suite based on Bootstrap 3 component colors, metrics and appearance. This skin can be easily customized in the Theme Builder (http://themebuilder.telerik.com/aspnet-ajax) in terms of colors which allows you to create Bootstrap like appearance for Telerik Ajax components which matches the colors of your Bootstrap apps and components.

If you have any other requests for Bootstrap, don't hesitate to share them with us.
=====================

<telerik:RadMaskedTextBox ID="RadMaskedTextBox2" Runat="server" Mask="<0..255>.<0..255>.<0..255>.<0..255>" ZeroPadNumericRanges="false" PromptChar="">  
</telerik:RadMaskedTextBox> 

Should render 192.168.1.1 instead of 192.168.__1.__1 

I would like to suggest a new control build from the same paradigm as the RadSocialShare.
The control should enable a website to provide an easy way to setup shared sign up / login from different providers on your website.

E.g. an easy way to let users sign up using their facebook account or Google account etc.

According to the following Telerik links, the radCheckBox being on a page with a radButton defaults the rendermode to lightweight.

https://docs.telerik.com/devtools/aspnet-ajax/controls/checkbox/troubleshooting/distorted-appearance

https://docs.telerik.com/devtools/aspnet-ajax/controls/checkbox/mobile-support/render-modes

The appearance is indeed distorted when used this way.  Changing my radbutton to lightweight changes the design and doesn't match with the overall them of the site.  To get the design I wanted, I used an asp:Checkbox instead of a radCheckBox.  

I'd like to request the radCheckBox and the other controls mentioned in the links to be able to be rendered in more than just lightweight.  If radCheckBox is the only one we can get, that's fine as I'm not sure if I would need the other ones.   

The attached picture shows the issue.
Thank you.

As of now RadEditor for SharePoint 2013 or sharepoint 2016 is not available, reason Telerik  had provided for non-availablity of RadEditor for List Items as it is handled from client end is not acceptable, since many other component providers do support similar functions with their editors. the reason / use case iam looking for is becoz of need to handle clipboard manager in editor which is not available in Multiple line of text column type of an SharePoint 2013 list,

Using https://products.aspose.com/slides is expensive if you want to programmatically create a powerpoint slide.
A typical UI component for input is seen in the attached slide (Spot Element on a performance grid), which would then be rendered into a powerpoint slide (spot on a grid). This is very typical in performance reviews, but also tracking High Flyers, eg are they too skilled for their current position and need to be promoted.
Telerik have existing components that could be used, just need to save as a PPT slide instead of a PDF. If there was a Web Component (reuse for HTML5 Chart code) then Export to PowerPoint  instead of PDF then you are almost there.

I love WebForms and the wealth in the Toolbar. 
I would like to write the payload of the web page in a webform and limit the round tripping with micro webservices, so there is no PostBack. Which means I can do more clientside in a KendoUI style. This would address the criticism of the bloat that comes with ViewState in webforms offering a leaner web page, but with all the advantages of the JavaScript tooling. 
For the most part a lot of this can be done already, would just prefer not to have any limitations in the controls that I can use for this. Just that there is such a driver now with the fashion of AngularJS/SPA applications suggesting that webforms cannot compete here.

Would be nice to have a  single sign on control (eg like http://www.gigya.com/)
What this means is that you can sign on/sign up  with any social login.
Would like this to work well with ajax controls and KendoUI
This sign on is megga important on mobile, but good for conversions on standard laptop or HD websites.

I think you may consider the following similar type of control(s) in future release.  I think the following is a good fit for use between a BI solution and standard reports.  It gives regular users some flexibilities to generate ad-hoc queries within an application.

The ASP.NET community really seems to be missing a proper property grid.
The only example I could dig out was the outdated implementation on codeplex:
http://propertygrid.codeplex.com/

I'd like to see one such implementation from Telerik.
