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.

7/28/2019

Could it be a license issue?

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>

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:

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

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.

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.

2. Go to 'Replace' tab.

3. Enter a white space for 'Find' text box.

4. Enter any character or word for 'Replace With' text box.

5. Hit on 'Replace All' button.

Reproducible in content which contains table elements and in the live demo: https://demos.telerik.com/aspnet-ajax/editor/examples/overview/defaultcs.aspx

I'm using couple of Rad Editor controls in my webpart and using ToolProviderID for performance optimization.
I'm initializing one rad editor toolbar from server side and using the same toolbar to provide other rad editors with their toolbar, Bascially I'm using ToolProviderID attribute to initialize other RadEditors, after doing this the Comments and Track Changes feature stop working although their options are selected in the toolbar.


<telerik:RadEditor RenderMode="Lightweight" runat="server" ID="RadEditor1" EnableTrackChanges="true" EnableComments="true">

After having a filter applied, filter value is not cleared when FilterOption was set to "NoFilter".


The following client-side logic would clear the textbox values before the filtering is applied if filter options are set to "NoFilter"

            function onCommand(sender, args) {
                if (args.get_commandName() == "HeaderContextMenuFilter") {
                    var firstTextBox = $("[id$='HCFMRTBFirstCond']")[0].control;
                    var firstFilterOption = args.get_commandArgument().split("|")[1];

                    var secondTextBox = $("[id$='HCFMRTBSecondCond']")[0].control;
                    var secondFilterOption = args.get_commandArgument().split("|")[3];

                    if (firstFilterOption.includes("NoFilter") && firstTextBox.get_value() != "") {
                        args.set_cancel(true);
                        var value = firstTextBox.get_value();
                        firstTextBox.clear();
                        var newArg = args.get_commandArgument().replace("|" + value + "|?", "||?");
                        args.get_tableView().fireCommand(args.get_commandName(), newArg);
                    }

                    if (secondFilterOption.includes("NoFilter") && secondTextBox.get_value() != "") {
                        args.set_cancel(true);
                        var value = firstTextBox.get_value();
                        secondTextBox.clear();

Missing background color of the Grid's headers in IE9 due to the unsupported by the browser linear-gradient. The issue can be reproduced with Skin="Web20".
