We are evaluating whether to use Telerik to redesign a legacy web app written using an old version of Telerik.

After downloading Trial version on fresh install of windows, I can't add ajax control to form. `I am using visual studio 2019, this is the first version of Telerik installed on this computer.  I just get the "Error Creating Control RadScriptManager1. They do show up in the toolbox so this surprises me.

Very latest version.

Could it be a license issue?

The current colors, #0082CC and #FFFFFF that are used for forecolor and backcolor, have 4.14:1 color contrast ratio: https://webaim.org/resources/contrastchecker/?fcolor=FFFFFF&bcolor=0082CC

The minimum required color contrast ratio is 4.5:1 for AA Compliance, and 7:1 for AAA Compliance.

A possible alternative color for the #0082CC blue can be #007CC.

The problem is similar and related to https://feedback.telerik.com/aspnet-ajax/1377444-getting-webresource-axd-not-found-error-404-when-searching-for-windows7-sprite-grid-png

Please add the new (Core) features for Drawer, PDF Viewer, Adaptive Grid and Adaptive Scheduler to the  ASP.NET AJAX controls.  Thanks.

I have a RadCheckboxList In an ASP Panel. When Enabling/Disabling the panel the CheckBoxList does not Enable/Disable.  I tested this with a simple mock up with additional controls that work as expected:

 

<asp:Panel ID="TestPanel" runat="server" Enabled="true">

<telerik:RadCheckBoxList ID="WeeklyDays" runat="server" Columns="4" AutoPostBack="false">

<Items>

<telerik:ButtonListItem Text="Monday" Value="2" />

<telerik:ButtonListItem Text="Tuesday" Value="4" />

<telerik:ButtonListItem Text="Wednesday" Value="8" />

<telerik:ButtonListItem Text="Thursday" Value="16" />

<telerik:ButtonListItem Text="Friday" Value="32" />

<telerik:ButtonListItem Text="Saturday" Value="64" />

<telerik:ButtonListItem Text="Sunday" Value="1" Selected="true" />

</Items>

</telerik:RadCheckBoxList>

<telerik:RadTextBox ID="TestText" runat="server"></telerik:RadTextBox>

<telerik:RadDatePicker ID="TestDate" runat="server"></telerik:RadDatePicker>

</asp:Panel>

<br />

<telerik:RadCheckBox ID="ToggleEnabled" runat="server" Text="Toggle Panel" AutoPostBack="true" Checked="true" OnCheckedChanged="ToggleEnabled_CheckedChanged"></telerik:RadCheckBox>

 

 

 protected voidToggleEnabled_CheckedChanged(objectsender, EventArgs e)

{

TestPanel.Enabled = Convert.ToBoolean(ToggleEnabled.Checked);

}

Reproduction steps:

Go to the Telerik demo at https://demos.telerik.com/aspnet-ajax/textbox/overview/defaultcs.aspx
In the Comment box, type "one two".  Do not let the textbox lose focus.
Highlight "two" and start to drag it to move it before "one". The other text ("one") will disappear, and is gone forever, as far as I can tell.

It can be also reproduced with this configuration:

<telerik:RadTextBox RenderMode="Lightweight" runat="server" ID="RadTextBox3" Width="200px" EmptyMessage="Enter comment" TextMode="MultiLine" Height="100px" Resize="None"></telerik:RadTextBox>

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

Hello,

There seems to be a bug with the RadEditor "Find and Replace" feature. I have recorded a screencast available here documenting the issue and will also provide below the information written: https://www.screencast.com/t/MXFawxIPp

Reproduction Steps:

• Open: https://demos.telerik.com/aspnet-ajax/editor/examples/overview/defaultcs.aspx
• Navigate to HTML view
• Click "Find and Replace" or press ctrl+f
• In the Find and Replace window, navigate to the replace tab
• In the Find field put an html tag (For example '<img' )
• In the Replace field put an html tag you with to convert that tag to (For example '<picture' )
• Press Replace All

Expected: '<img' is replaced with '<picture'

Actual:'<img' is replaced with '&lt;picture'

Notes:This seems to be an issue with encoding as &lt; is a less than tag. As you can see in the video, I do not think there is a way to escape the character to allow it to be replaced correctly. If you have additional questions, please ask.

 

Best Regards

RadCodeBLock and RadScriptBlock is not able to handle the server tags for all case scenarios, hence RadAjaxManager throws the exception mentioned in the title.

Hi,

It will be great to have a property in a raddock to automatically adjust its height/width to occupy the new space created when some other raddock in the layout is minimized. This will avoid the need for the user to adjust the height/width of the raddock which is still visible.

 

I have a problem with the deletecommand of the asp.net radgrid control (Telerik.Web.UI 2019.1.215.40).

This happens only in the latest release of Chrome.

I hope you can replicate this issue and eventually fix it. 

When the ribbon bar is set to RibbonBarFloating, RibbonBarPageTop or RibbonBarShowOnFocus the menus cut off so you can't access menu items that would be displayed below bounds of the ribbon bar.

You can see this happening at:

https://demos.telerik.com/aspnet-ajax/controls/examples/integration/ribbonbarandeditor/defaultcs.aspx?product=editor

I have also supplied a snip of the issue.

Hi,

 

Trying to use a web testing tool (Selenium) and using xpath is not always working.  I was wondering if it would be possible to always add an ID property to controls, especially in drop downs etc. so that it can clicked properly.

We are using Telerik Ajax controls in our web site. We need a functionality where user can read a barcoded value using camera device or barcode image on a web page.

We found that Ajax Barcode control has only Barcode generator functionality.

Is there a way we can read barcode value on web site?

We could use a new calendar control that works differently than the scheduler, or any existing calendar control. 

Overview of features and how it would work:

• User selects a month, the calendar auto draws the month as a calendar view with options to set day of week as short, medium or full length.
• The calendar has an input field which can handle validation if needed. Validation example:
  • Only accept integers
  • In logic, if X = Whatever, then only allow input value of 1.

• Treat as an array so we could loop through the control and read each value for saving to database or to take action on from code.

• Example shown below. This is dynamically creating using tables and HTML. Not the nicest looking, and a pain to reuse anywhere. We could make use of this type of control in a lot of applications.

   

 

After the alert was confirmed, a Post Back is expected which does not happen due to a JavaScript exception: Cannot read property 'toString' of null

i have a feature request

- Image map input

Based mapify,js sample below :

http://etiennemartin.ca/mapify/

I have use it before, storing areas and values in the databases, but the output is hyperlink.

I want it as asp.net input control that have selectedvalue property, i want server side value as the result. Maybe i can borrow hiddenfield or something. But it's wasting time.

Please, add image control input into your collection. It's very usefull i guess.

Bug introduced in build 2019.1.115+ causes 3 extra <p>&nbsp;</p> when user presses Enter key in FireFox.  Happens when Editor is in a Wizard with more than one step.  Bug does not occur in builds prior to 2019.1.115.

Try this to reproduce:

 <telerik:RadWizard runat="server" ID="rwMain" BorderStyle="Solid" BorderColor="LightGray" BorderWidth="1px" RenderMode="Lightweight" DisplayNavigationButtons="True">
        <WizardSteps>
            <telerik:RadWizardStep ID="RadWizardStep2" Title="Content Template" StepType="Step">
                <h1>hello!</h1>
            </telerik:RadWizardStep>
            <telerik:RadWizardStep ID="RadWizardStep3" Title="Content Editor" StepType="Step">
                <telerik:RadEditor ID="ContentEditor" runat="server" RenderMode="Lightweight"></telerik:RadEditor>
            </telerik:RadWizardStep>
        </WizardSteps>
    </telerik:RadWizard>

This can be reproduced with the following sample:
