Any way to prevent the chart from refreshing/redrawing/repainting while I'm updating it?

Hi Steve,

Thank you for writing back.

If I understand correctly you would like to remove the flickering when drilling in within your RadChartView. This behavior is caused by our themes which define an AnimatedStateTransition setting for several RadProperties of the chart point element. 

In order to achieve your task you have two options:
  1. Disable and enable the animations in the handler of the Drill event: 
    private void radChartView1_Drill(object sender, DrillEventArgs e)
    {
        ThemeResolutionService.AllowAnimations = false;
     
        // Your logic for the drill navigation
        switch (e.Level)
        {
            case 0:
                break;
            case 1:
                break;
            case 2:
                break;
        }
     
       ThemeResolutionService.AllowAnimations = true;
    }
  2. Change the theme settings in the Visual Style Builder tool.

I am also sending you attached a modified ControlDefault theme as well as a short video showing where exactly these settings are located.

I hope this helps. Should you have further questions please do not hesitate to write back.

Hi,

At the moment I have an autocomplete box which opens another tab. The autocompletebox list overlaps Tiles, when a selection is selected that overlaps a tile, it'll trigger the selection event AND the tile event. May I ask how do I set it up such that it'll only trigger selection event.

Telerik Reporting REST Service with Pacific AppServer

April 11, 2016, 12:44 pm
$

Hello Mircea,

Telerik Reporting provides an HTML5 Viewer (Javascript, CSS, HTML client-side widget) served via dedicated REST service.

The HTML5 viewer can be added in any web application, because the Javascript widget does not require any assembly references. The viewer communicates via short requests with the server machine where reports are generated.

The Reporting REST service requires a Windows machine with installed .NET4+ full framework, because reports are processed and rendered on the machine where the service is running. For more details check Requirements.


In case the idea is to consume the data in reports, you can create a custom data access layer with a client for the generated data services. The retrieved records can be used in reports via ObjectDataSource. Please consider the example illustrated with OData service in Connecting Telerik Reporting to OData feeds.
To use ObjectDataSource in the Standalone Report Designer, the data access layer can be built in an assembly extending the designer tool - Extending Report Designer.

There are also OpenClientDataSource and SqlDataSource.components allowing you to connect data.


If you need more information, please elaborate on the scenario, the hosting environment, data that will be used and the purpose of reporting product.

Stef

RadWizard Step validationgroup

April 11, 2016, 12:44 pm
$

sender.set_activeIndex() seems to trigger validation as of 2016Q1. Like the OP, I have a RadWizard with 4 individually validated steps. I want to allow users to step backwards no matter what. I only want them to be able to step forward if the current page passes validation. Using RenderedSteps="All" and the above JavaScript OnClientButtonClicking, I still can't click either the Previous button or the entries for previous steps in the navigation bar. In both cases validation triggers and my 'required' messages appear but the active step does not change. I even tried manually triggering $find("RadWizardClientID").set_activeIndex(0); in the browser's JavaScript console only to have validation trigger and the active step remain the same. 

I've gotta say, compared to the standard ASP.NET Wizard, the RadWizard is a complete pain in the butt when it comes to validation. I can't for the life of me figure out when I'd want this thing to validate more than 1 step at a time, or when I'd want it to prevent me from accessing a previous step due to the current step's validation results.

WebForms ReportViewer and SessionState serialization

April 11, 2016, 12:44 pm
$

Hello Jeff,

With the old ASP.NET WebForms ReportViewer and out-proc session state mode, the data source has to be binary serializable:
As the data sources are kept in the session state, it is highly recommended to use the built-in Data Source Components. As a last resort you can use the NeedDataSource event to populate the report with data. Otherwise the session state will either become very large, especially when using large datasets or the data for the report will not be serialized at all if it cannot be binary serialized/deserialized (e.g. business objects, anonymous types, data adapters, etc.). You should restrain from setting an instance of your business object directly as a data source, as it would be serialized multiple times into the session.
Full details are available in Design Considerations for Out-proc Session State.


With the HTML5 Viewer, all modifications of the report should happen on the server. Thus data can be passed in the data items' NeedDataSource events - Using Report Events.
Or you can use a custom report resolver for the Reporting REST service, which allows you to resolve in code which report to be displayed and with what settings. Please consider the example in Changing a parameter's datasource connection string at runtime.

Stef

Getting Kendo Editor to edit mode when a button is clicked

April 11, 2016, 12:44 pm

I have a Kendo Editor, defined as below:

@(Html.Kendo().Editor()
          .Name("RestrictionsEditor")
          .Tag("div")
          .Tools(tools => tools
                .Clear()
                .Bold().Italic().Underline().Strikethrough()
                .JustifyLeft().JustifyCenter().JustifyRight().JustifyFull()
                .CreateLink().Unlink()
                .InsertImage()
                .TableEditing()
                .FontColor().BackColor()
          )
          .Value(@<text><p> This editor is readonly and will get into edit mode only after 'Edit' button is clicked</p></text>))

 

I have editor as readonly initially and I am doing that as below:

   <script type="text/javascript">
                $(function ()

                  {

                          var editor = $("#RestrictionsEditor").data("kendoEditor"),
                          editorBody = $(editor.body);

                          // make readonly
                          editorBody.removeAttr("contenteditable").find("a").on("click.readonly", false);
                })
                 
   </script>

 

Now, I have been trying to get the editor to edit mode when a button is clicked.

I have defined my button as below right above my editor:

  <button class="btn-sm" id="edit">Edit</button>

 

And I am writing the Javascript as:

 <script type="text/javascript">
                $("#edit .btn").click(function () {
             
                var editor = $("#RestrictionsEditor").data("kendoEditor"),
                editorBody = $(editor.body);

                
                editorBody.attr("contenteditable", true).find("a").off("click.readonly");
                })
 </script>

 

When I run my code, the editor is in readonly mode initially and as soon as I click 'Edit' button it takes me back to the original page, out of the modal. Forgot to mention, Editor is inside of a tab in modal.

 

How can I achieve this behavior - Kendo Editor in readonly mode initially and after 'Edit' button is clicked, Editor gets in edit mode.

 

Thanks!

I have a Kendo Editor defined as below:

                    editorBody.removeAttr("contenteditable").find("a").on("click.readonly", false);
                })
                   
            </script>

 

I want to get editor in 'Edit' mode only when a button is clicked. Below is how I am defining my button:

                         <button class="btn-sm" id="edit">Edit</button>

 

I have defined my button just before initializing Kendo Editor.

 

And below is how I am trying to get the editor to edit mode:

         <script type="text/javascript">
                $("#edit .btn").click(function () {

                var editor = $("#RestrictionsEditor").data("kendoEditor"),
                editorBody = $(editor.body);
                
                editorBody.attr("contenteditable", true).find("a").off("click.readonly");
                })
            </script>

 

Now, when I run application my editor is in read only and when I click 'Edit' button, editor doesn't gets in edit mode and instead as soon as I click button, I m directed to the original page. Forgot to mention, my editor is inside a tab, which is inside of a modal.

 

Can you tell  me where I am doing wrong and how can I acheive th

AFAIK there is no translator for Kendo UI multi select. Any example you have will be appreciated.

Just to clarify, I have the same problem as the OP.  

1. In the current release , the RadGrid does not save it's expanded/collapsed state when the grid transitions from read mode to edit mode ?

2.Is the proposed solution here, still the best solution, as it's been quite a long time, and seems the Telerik control should do this already?

Typescript & kendo.mobile.application

April 11, 2016, 12:44 pm

I am starting a new project using the Kendo Mobile controls (release 2016 Q1 SP2), and I am using TypeScript.  When I attempt to instantiate my kendo.mobile.application, I am getting errors from TypeScript and the issue appears to be that the type definition file does not contain the correct definition.

Here is my simple TypeScript code:

varapp = newkendo.mobile.Application(document.body,
    {
        transition: 'slide',
        skin: 'nova',
        init: function() {
            //don't do this for android, causes issues with scrollView and swiping
            kendo.UserEvents.defaultThreshold(kendo.support.mobileOS.device === 'android'? 0 : 20);
    }
});

This code works fine when I run it in JavaScript, but after trying it in TypeScript and I getting compiler errors - it's complaining about the "skin" and "init" options.  The errors are shown in the attached images (skin.png and init.png).  The skin configuration option is shown in the Kendo docs (http://docs.telerik.com/kendo-ui/api/javascript/mobile/application#configuration-skin), so is it just a matter of the type definition file being incorrect?  Or is there something else I need to do?

Also, looking over the type definition file, it appears that the ApplicationOptions parameter used when initializing the application object is missing quite a few items that are listed in the Kendo documentation (http://docs.telerik.com/kendo-ui/api/javascript/mobile/application) - things like browserHistory, hashBang, modelScope, useNativeScrolling, etc. So this seems like more than just a minor oversight, which leads me to my other question...is TypeScript fully supported for Kendo Mobile?  Just want to make sure I'm going down the "sanctioned" path before I get too far into my project.

IE11 intermittent Yellow Dot and freeze

April 11, 2016, 12:44 pm

We have had problems with RadAsyncUpload in IE11 where it will give a yellow dot and freezes when uploading files.  This has been happening since our users started using IE11 (on Windows 8.1).  Previously they used 10 without issue.

This does not happen if we direct them to Chrome.  The only way around it we have found is to turn off the FileApi Module for IE.  We do utilize drag and drop so when that module is disable that functionality is lost.  I am using the latest version of the controls 2016 Q1.

I also tried to emulate IE10, but that does NOT solve the issue.  We run with ie=edge meta tag.

The problem is intermittent and I have not been able to reproduce it myself.  I have seen some similar threads on problems like this including this one: http://www.telerik.com/forums/radasyncupload-1fc6f6296712

Is there any kind of known issue or workaround?  It is difficult to troubleshoot given the intermittent nature.

<telerik:RadAsyncUpload  Skin="Default"OnClientFilesUploaded="saverecord"ID="faupload"runat="server"
        MultipleFileSelection="Automatic"TargetFolder="\\xxxxxx\xxxxxx"

EditForm CSS adding garbage to grid

April 12, 2016, 12:58 pm

Greetings!

I'm having an issue with a RadGrid using an EditFormTemplate; whenever I click my edit button on an item of this rad grid, the item goes into edit mode fine and my controls appear below them item. However, when the CSS for the row being in edit mode gets applied, it adds some peculiar artifacts to my grid. I get a blue line about 15 lines of text from the top of the item being edited. It's worth pointing out that the varchars being exposed by this grid are very large, which might have something to do with the issue; it only occurs when modifying an exceptionally long list of codes.

Please find attached screenshots of the problem behavior.

Screenshots include a before and after [edit button clicked] of the item in question, and the behavior exhibited.

It sort of hangs there, strangely in the middle of the original radgrid item. These elements don't appear to be actual controls; they seem to be part of a repeating background being applied by the CSS for an edit form item.

Here's my markup for the grid in question:

<telerik:RadGridID="rgCrosswalkView"AutoGenerateColumns="false"runat="server">                                       
    <MasterTableViewDataKeyNames="CrosswalkID, CrosswalkGroupID, CPTs, ICDs">

                    </div>
                </div>

                    <divclass="col-sm-8">
                          
                    </div>
                </div> 
            </FormTemplate>
        </EditFormSettings>
    </MasterTableView>
</telerik:RadGrid>

And here is the CSS which appears to be giving me trouble, pulled from dev console. The offending line is commented out. Disabling that attribute makes the coloration of the edit form item go back to default, but removes the garbage repeating x.

.rgEditRow {
    /* background: rgba(205,205,205,0.75) 0 -4900px repeat-x url('WebResource.axd?d=ifcjPV8aj2vMt9az-6wWmwZqcD65tft-V-aE6ooNIutn9jwr_s82sxYh…9mFxF_3cAUoYtM8o9U5-M7wLDeK47M_h5TDjLXEugyZbr0sNXz01&t=635932205533629626'); */
    color: #000;
}

I can probably override it by "cancelling" the class in some way, but would honestly prefer it perform the coloration as it intends to, without the garbage.

Any assistance would be appreciated.
