I have a project that uses the ASP.NET Ajax controls and I would like to upgrade to the newest version (2021). Is it just a matter of switching the DLLs and skins or are there breaking changes? After upgrading do I need to test every page with a Telerik control on it?

Thanks,

Tim

Hi Telerik team,

We found an issue for the editor, if we add html tag in the html mode and back to design mode, the tag got changed.

How to reproduce it:

1. go to RadEditor Demo page, paste following html to editor "<p><font size="4"><br>
Please join us for the Jefferson Virtual Academy Open Forum* on Zoom to get additional information:<br>
</font></p>"

2. switch to design mode, the html changes to

<p><span style="font-size: 18px;"><br />

Is there any way to fix it?

Thanks in advance,

Lan

Hello,

Just started to play with this radTabStrip control.

I have 6 tabs along the top.

I have a radMultipage control right after the tabctrl.

I have a grid on the first tab and a radcalendar & grid on the 2nd tab.

When I run I see the tabs but the controls on tab 1 & 2 do not show up.

i am probably doing some thing dumb but cant see it.

<td id="appTabCrtlr1c" colspan="12">
                    <telerik:RadTabStrip ID="RadTabStrip1" runat="server" ReorderTabsOnSelect="True" SelectedIndex="0">
                        <Tabs>
                            <telerik:RadTab runat="server" Selected="True" Text="Root RadTab1">
                            </telerik:RadTab>
                            <telerik:RadTab runat="server" Text="Root RadTab2">
                            </telerik:RadTab>
                            <telerik:RadTab runat="server" Text="Root RadTab3">

I am upgrading an old project to the latest UI for ASP.NET AJAX that is currently using bootstrap V3.

If I upgrade to the current version of Telerik what version of bootstrap should I use?

We just upgraded to .Net Framework 4.5. We are using UI for ASP.NET AJAX Q3 2012 SP2. I have a GridAttachmentColumn that works fine in our development environment. When deployed to QA we get the below error when clicking on the + sign to add a new record to the grid and the Grid Attachment control does not appear.
Error: Object doesn't support property or method 'registerControlProperties'
Anonymous function [Line: 395, Col: 1], Telerik.Web.UI.WebResource.axd
Global code [Line: 5, Col: 2], Telerik.Web.UI.WebResource.axd

Thanks in advance for any help on this issues.

I'd like to have a RadButton whose icon differs between two images depending on the value of the field. I'm not sure if this is the best approach, but I am defaulting to one specific icon and attempting to change it in the _ItemDataBound method. However, I can't seem to figure out how to access the icon from the RadButton:

                        <ItemTemplate>
                            <telerik:RadButton RenderMode="Lightweight" ID="Image2"
                                CommandName="OnCommentToggleHandled" runat="server">
                                <Icon PrimaryIconUrl='<%# DataBinder.Eval(Container.DataItem, "Dismissed").Equals(true) ? "/App/images/green-check.png" : "/App/images/comment.gif" %>' runat="server"></Icon>
                            </telerik:RadButton>
                        </ItemTemplate>

        protected void StatusGrid_ItemDataBound(object sender, GridItemEventArgs e)
        {
            if (e.Item is GridDataItem)
            {
                GridDataItem dataBoundItem = e.Item as GridDataItem;
                RadButton foo = dataBoundItem["Dismissed"].Controls[1] as RadButton;

                if ((dataBoundItem["Important"].Controls[1] as Image).ImageUrl.Contains("green-check.png"))
                {
                    dataBoundItem.BackColor = System.Drawing.Color.LemonChiffon;
                }
                else if ((dataBoundItem["Dismissed"].Controls[1] as RadButton).PrimaryIconUrl.Contains("blank.gif"))
                {
                    e.Item.CssClass = "rgRow unhandledMessage ";
                }

                dataBoundItem["Text"].Text = WebUtility.HtmlDecode(dataBoundItem["Text"].Text);
            }
        }

Here's my code:

 function ShowForceNote2() {
                var url = 'CustNoteD.aspx';
                var oWindow = window.radopen(url, "rwFN");
                oWindow.SetTitle('Note');
                oWindow.SetActive(true);
                oWindow.set_modal(true);
                oWindow.set_enabled(true);
                oWindow.set_behaviors(Telerik.Web.UI.WindowBehaviors.Close);
                oWindow.Maximize();
            }

Here's my html:

<telerik:RadWindowManager ID="rwm" runat="server" ReloadOnShow="True" ShowContentDuringLoad="False">
    <Windows>
        <telerik:RadWindow ID="rwFN" runat="server" Title="Note" ReloadOnShow="True"
              ShowContentDuringLoad="False" DestroyOnClose="True" Style="z-index: 999999;"
              Behaviors="Close" VisibleStatusbar="False" />
    </Windows>
</telerik:RadWindowManager>

Hi there,

we are trying to implement the drill down for the bar chart and pie chart. 

I need help to achieve this we are generating the chart in a completely dynamic way we don't have any code related to rad control on the Aspx page. 

please help me if anyone has samples.

I am working on xHTML documents in rad editor. I set as follows:
ArcRadEditor.ContentFilters = EditorFilters.ConvertToXhtml;

when I open the xHTML document in editor and save it, some characters in there change and editor generates an invalid xHTML.
editor converts these:
&#8220; -> “
&#8221; -> ”
&#8217; -> '

all 3 converted characters are invalid xHTML

attached are two very small files: Original.htm and Edited.htm, so you can see how the save process tranforms the file.
please note that my original file is VALID xHTML, but after I save it in editor it becomes invalid xHTML.

how do I save xHTML in editor without corrupting it?
thank you
