When attempting to view the page in design view, here's what it looks like:

 

Here is the markup:

    <telerik:RadPanelBar ID="RadPanelBar1" runat="server">
        <Items>
            <telerik:RadPanelItem runat="server" Expanded="True" PreventCollapse="true">
                <HeaderTemplate>
                    <div ID="content-header">
                        Auditing Report | GPO Changes For User
                    </div>
                </HeaderTemplate>
                <ContentTemplate>
                    <div ID="content-body">
                        <telerik:ReportViewer ID="ReportViewer1" runat="server" ReportBookID="" Width="100%" Height="12in">
                        </telerik:ReportViewer>
                    </div>
                </ContentTemplate>
            </telerik:RadPanelItem>
        </Items>
    </telerik:RadPanelBar>

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">
    <TrackChangesSettings Author="AuthorName" CanAcceptTrackChanges="true" UserCssId="reU0" />
    <Tools>
        <telerik:EditorToolGroup>
            <telerik:EditorTool Name="AcceptTrackChange" />
            <telerik:EditorTool Name="RejectTrackChange" />
            <telerik:EditorTool Name="AcceptAllTrackChanges" />
            <telerik:EditorTool Name="RejectAllTrackChanges" />
            <telerik:EditorTool Name="EnableTrackChangesOverride" />
        </telerik:EditorToolGroup>
    </Tools>
</telerik:RadEditor>
<telerik:RadEditor ID="RadEditor2" runat="server" ToolProviderID="RadEditor1" EnableTrackChanges="true" EnableComments="true"></telerik:RadEditor>
<telerik:RadEditor ID="RadEditor3" runat="server" ToolProviderID="RadEditor1" EnableTrackChanges="true" EnableComments="true"></telerik:RadEditor>

When I try to replace a white space in RadEditor, it is able to replace the words at the first line. The second one and onwards are not able to replace.

Step:

1. Open 'Find And Replace' dialog.

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

<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.

What is EOL for this version.
UI for ASP.NET AJAX R1 2017 SP1 (version 2017.1.228)

When the scripts are loaded through a script manager with enabled CDN and RadScriptManager.CombinedResource="Enabled", JS error will be thrown then the filtering button of the Grid is clicked.

Code to reproduce the problem:
        <telerik:RadScriptManager ID="RadScriptManager1" runat="server">
            <CdnSettings TelerikCdn="Enabled" CombinedResource="Enabled" />
        </telerik:RadScriptManager>

        <telerik:RadGrid ID="UserDetailsGrid" runat="server" AllowFilteringByColumn="true" OnNeedDataSource="UserDetailsGrid_NeedDataSource"
            EnableHeaderContextMenu="true" EnableHeaderContextFilterMenu="true">
        </telerik:RadGrid>

C#:
        protected void UserDetailsGrid_NeedDataSource(object sender, Telerik.Web.UI.GridNeedDataSourceEventArgs e)
        {
            var list = new[] {
                    new { FirstName = "F1", LastName ="L1"},
                    new { FirstName = "F2", LastName ="L2"},
                    new { FirstName = "F3", LastName ="L3"},
                    new { FirstName = "F4", LastName ="L4"}
                    }.ToList();
            UserDetailsGrid.DataSource = list;
        }

Can be reproduced with the following page setup:

The ContextMenu popup is not position properly relative to its target element when the page is horizontally scrolled in Edge. The problem is reproducible with R2 2018.

Steps tp reproduce:
1. Run the code below and scroll the page to the right
2. Right click over a number

Affects RadCloudUpload and RadAsyncUpload combined with RadProgressArea. Manifests most often on slow networks or very large files.
Scroll down for workarounds for both cases.

NOTE: RadCloudUpload issue is logged separately - https://feedback.telerik.com/Project/108/Feedback/Details/258958-cloudupload-progress-shows-more-than-100-when-uploading-a-file

WORKAROUND FOR PROGRESS AREA is to round down the data, as it seems the server reports more bytes uploaded than they actually are, and that tends to happen under slow network conditions

<telerik:RadAsyncUpload RenderMode="Lightweight" runat="server" ID="RadAsyncUpload1" MultipleFileSelection="Automatic" EnableInlineProgress="false" />
<telerik:RadProgressManager runat="server" ID="RadProgressManager1" />
<telerik:RadProgressArea RenderMode="Lightweight" runat="server" ID="RadProgressArea1" OnClientProgressUpdating="OnClientProgressUpdating" />
<script>
function OnClientProgressUpdating(sender, args) {
    //debugger
    if (args._progressData.PrimaryPercent > 100) {
        args._progressData.PrimaryPercent = 100;
    }
    if (args._progressData.PrimaryValue > args._progressData.PrimaryTotal) {
        args._progressData.PrimaryValue = args._progressData.PrimaryTotal;
    }
    console.log(args.get_progressData());
}
</script>

WORKAROUND FOR CLOUD UPLOAD is to add the following script at the end of the form that will override the built-in XHR handilng to change the way the totals are calculated:

        <script>
            Telerik.Web.UI.RadCloudUpload.HandlerUploader.prototype._initializeXmlHttpRequest = function () {
                this._xhr = new XMLHttpRequest();

                var that = this,
                    module = this._module,
                    xhr = this._xhr;

                xhr.onreadystatechange = function readyStateChanged() {
                    if (xhr.readyState == 4) {
                        if (xhr.status == 200) {
                            that._successfulResponseStatus(xhr);
                        }
                        else if (xhr.status != 0) {
                            that._failedResponseStatus(xhr);
                        }
                    }
                };

                xhr.upload.onprogress = function (event) {
                    that._uploadedSize += event.loaded;

                    var percents = Math.round((event.loaded / event.total) * 100) + "%";

                    module._renderingManager.updateRowProgress(that._uploadingEntity.row, percents, true);
                };
            }
        </script>

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();
                        var newArg = args.get_commandArgument().replace("|" + value + "|?", "||?");
                        args.get_tableView().fireCommand(args.get_commandName(), newArg);
                    }
                }
            }

Some colors (for example #ccffff, #ccccff, #e5f2ff, #eef9fc, #003366, #006400) are not properly  applied in the Colorize tab of the Visual Style Builder and choosing one of them results in setting a different color.

I am seeing a strange problem when opening LinkManager dialog from RadEditor. The width of the dialog keeps decreasing on successive opening of the dialog. Sample page code to reproduce this is given below.

Reproducible in every browser.

When a RadEditor or SPRadEditor in a custom WebPart for SharePoint 2013 is placed in an UpdatePanel or RadAjaxPanel it is not ajaxified and loses its content after a post back.

The RadFormDecorator decorated checkboxes in the Grid are hard to read when checked in the following skins:
BlackMetroTouch, Bootstrap, Glow, Metro, MetroTouch, Office2010Black, Telerik, WebBlue

Screenshot with Telerik Skin:
https://www.screencast.com/t/1P2hyvWNX

Steps to reproduce:
1. Open http://demos.telerik.com/aspnet-ajax/formdecorator/examples/formdecoratorandtelerikcontrols/defaultcs.aspx?skin=Telerik
2. Scroll to the Grid
3. Select one or all checkboxes
Result: The selected color of the checkbox almost matches the background color

Could it be possible to see you developing a chat component to offer chat possibilities on a telerik Ajax Website?

Would be great

Thanks for all you do to simplify our developer life !
