I am using the AutoComplete control in tag mode, and I have created a button which will drop down the full tag list, based on some code I found in the forums or knowledgebase somewhere. It works nicely, unless I wrap it in an ajax panel. After a postback, the button no longer works - I get a javascript error: "Unable to get property 'itemDataBound' of undefined or null reference" in jQueryPlugins.js at line 237.

Here is my code:

var autoComplete = $find("<%= tag_box.ClientID %>");
var dropDown = autoComplete._dropDown;
var itemData = autoComplete._dropDownItemData;
setTimeout(function (e) {
   dropDown.populate(itemData, true);
   dropDown.open(autoComplete._getDropDownPositionInfo());
   dropDown.highlightNext();
   $('li.racItem').css('display', 'list-item');
}, 200);

The error occurs during the call to 'populate()'

The AutoComplete control works fine by itself after the postback. The tags list is populated, and I can add and remove tags using the keyboard without any fuss.

The script and the AutoComplete are contained in a user control (ascx) which is contained in another user control which has the ajax panel. The script is wrapped in a RadScriptBlock.

I also have two event handlers which I add to the AutoComplete  control, like this:

autoComplete.add_entryAdding(tagEntryAdding);

autoComplete.add_entryRemoved(tagEntryRemoved);

The events do not get called after a postback. I set the handlers from a jQuery 'ready' with a small timeout. Works fine before postback. but not after. The 'ready' code gets called (though for some reason I can't catch it in the browser debugger after postback).

I know I am missing something about how ajax and scripts and user controls work together, but I can't figure it out.

I develop a website with ASP.NET(C# Webform) and Visual Studio 2012. I use RadTabStrip with RadMultiPage in my webpage, but I deploy to IIS. And then I use my iPad mini to switch rad tab, it appear error message as below:

  「safari error a problem occurred with this webpage so it was reloaded」

in Chinese is:

  「此網頁發生錯誤，因此重新載入。」

or

  Safari 無法打開網頁
  錯誤碼為 WebKit encountered an internal error

I run the same website on Android device(SAM SUNG Galaxy Tab4). There is no problem during I switch the webpages.

Does somebody know how to resolve this problem? Is it belong trail version problem?

It looks like the CSS gets messed up in chrome on the Upload dialog. Is there a CSS fix that can correct this?

I attached a screenshot of the difference between Chrome and IE and can provide an example project of recreating the issue if need be.

Since last Chrome update version 58 we have visual bugs in ours RadWindow. We found out that it was because of that css class : 

html:first-child .RadWindow ul {
float: right;
border: 1px solid transparent;
}

It is automatically included in the Telerik.Web.UI.WebResource.axd comming from Telerik.Web.UI.Skins.Window.css. We first tough that it was a Chrome bug, but after investigating a little bit more, we realized that chrome was proccessing that css class like it is supposed to. We also found out that firefox is also processing that class the same way as Chrome do. Is there a way to remove that css? 

thanks

Hi friends,

I want to create a menu like following link in server side. that's great menu style.

http://demos.telerik.com/aspnet-ajax/menu/examples/functionality/templates/defaultcs.aspx

I made a research and there are tons on questions about how to achieve it most of them answered by telerik team "partially" yet there's no complete answer.

I wonder is there a reason why a complete simple answer for creating the menu at above link never exists ? questions and answers are still there since 2012 and no complete example ?

came on guys, can you please provide official code that works on server side and generates a menu at link above ? no need complex application scenarios or anything. obviously people still need it.

Also the reason we buy telerik products is simplify our tasks.

Please can you solve my problem. obviously I don't want my programmers to spent more time on discovering telerik menu item. (by the way its great item:)

best.

Hi,

On Telerik RT version v4.0.30319 the ul & li formatting isnt working on the recurrence editor of a radScheduler - please see attached pic.

Please can someone offer some css ideas to format the opt boxes to the left of the labels? This is driving me mad.

Thanks so much,

CB.

Hello ,

Can any body help me with the below design in telerik using LinearGauge Horizontal ..

Please reply asap..Thanks.

Hello I am using RadProgress bar of  chunk type,

When the chunkCount = 3 it generates incorrect width style for completed steps, it uses the comma instead of the dot so 33,33334% instead of 33.33334%.

So that it is not working as expected.

version: Telerik_UI_for_ASP.NET_AJAX_2016_2_607_Dev

code behind:

rpb_reviewMail.MaxValue = dataTable.Rows.Count;
rpb_reviewMail.ChunksCount = dataTable.Rows.Count;
rpb_reviewMail.Value = currentStep;

aspx:

<telerik:RadAjaxPanel runat="server">
                                <telerik:RadProgressBar RenderMode="Lightweight" runat="server" BarType="Chunk" Skin="MetroTouch" MinValue="0" Width="100%">
                                </telerik:RadProgressBar>

</telerik:RadAjaxPanel>
