Hi, i'm having troubles using RadDatePicker; i tried to build a layout like bootstrap without success.

I would transform RDP like

<div class="input-group date">
  <input type="text" class="form-control"><span class="input-group-addon"><i class="glyphicon glyphicon-calendar"></i></span>

so how can i do it?
I obtained only a little success setting

CssClass="form-control" for DateInput part.

Thank you.

Hello Emanuele,

I am afraid with the current rendering on the RadDatePicker this behavior cannot be achieved only by adding a simple CssClass. However you can build a custom Skin or wait to the next release where the Bootstrap Skin will be built in.


Check out the Telerik Platform - the only platform that combines a rich set of UI tools with powerful cloud services to develop web, hybrid and native mobile apps.

Hi @Galin, is this feature still spending? I am also having the same trouble when using Bootstrap template and RadDatePicker not working (not getting popup calendar) in Bootstrap styles.

Hi Deepu,

We have an article that addresses the Style issues that may be caused by the Twitter Bootstrap. Please visit the Fix incorrect appearance in Telerik controls when using Bootstrap library for the solution.

There is also a chance that the issue is caused by a JavaScript error. That will prevent the RadDatePicker to function properly. 

In that case, you open the Browser's DevTools and double-check the Console tab for JavaScript errors. If you see any, you will need to eliminate them to ensure the proper behavior of Telerik Components.

For tips and details about Debugging apps in the Browser, you can check out the following articles:


If my suggestions do not help fix the issue, I will need to see the problem. Please share the RadDatePicker markup code, tell us which bootstrap version you have included. Once we have enough information to replicate the problem, we can tell you how to fix it.

Telerik Web UI for ASP.NET AJAX Components are more complex and they render a specific structure and may not be compatible with Twitter Bootstrap styles.

If you add this RadDatePicker Component to the page:

<telerik:RadDatePicker ID="RadDatePicker1" runat="server"></telerik:RadDatePicker>


This will render the following HTML element and structure

<div id="RadDatePicker1_wrapper" class="RadPicker RadPicker_Default">
    <!-- 2022.1.119.45 -->
    <input style="visibility: hidden; display: block; float: right; margin: 0 0 -1px -1px; width: 1px; height: 1px; overflow: hidden; border: 0; padding: 0;" id="RadDatePicker1" name="RadDatePicker1" type="text" class="rdfd_ radPreventDecorate" value="" title="Visually hidden input created for functionality purposes.">
    <div id="RadDatePicker1_dateInput_wrapper" class="RadInput RadInput_Default">
        <input id="RadDatePicker1_dateInput" name="RadDatePicker1$dateInput" class="riTextBox riEnabled" type="text">
        <div class="rcSelect">
            <a title="Open the calendar popup." href="#" id="RadDatePicker1_popupButton" class="rcCalPopup"></a>
            <div id="RadDatePicker1_calendar" class="RadCalendar RadCalendar_Default" style="display: none;">
                <div class="rcTitlebar">
                    <a id="RadDatePicker1_calendar_FNP" class="t-button rcFastPrev" title="<<" href="#">

Such structure is required for all the Functionalities the RadDatePicker can offer, and we do not have plans to change that to make it comply with Twitter Bootstrap's CSS Library.

Telerik Assemblies also deliver built-in skins for Telerik Components, see Built-in Skins.

If you wish to change the appearance of Telerik Components, you can follow the instructions from the Changing the Appearance of a Control article.

For instance, if you wanted the RadDatePicker to look similar to Bootstrap, you can set its Skin property value to Bootstrap. 

<telerik:RadDatePicker ID="RadDatePicker1" runat="server" Skin="Bootstrap"></telerik:RadDatePicker>


This will be the result:


If you choose to style the control from scratch, you can disable the built-in Skins by setting the EnableEmbeddedSkins property to false.

That will result in the following appearance:
