The RadDatePicker is not working on IE8.
With Firefox 15 is working OK please look at the image attached to this thread.

This happen after upgrading from version: 2012.1.411 to 2012.2 912

This issue maybe related to an earlier one I've already reported.

Hello Ricardo,

Based on the information I can not tell for sure what is the cause of this issue. Try setting the DateInput->EnableSingleInputRendering of the RadDatePicker to false. Also could you show us the aspx code so we could give you a more straight forward solution?

All the best,

The code is as follows:
<telerik:RadDatePicker runat="server" ID="TEL_DP_EntryDate" TabIndex="4" Enabled="false" >
</
telerik:RadDatePicker>

When I changed it to the configuration you mentioned i got the following code auto-generated:


<telerik:RadDatePicker runat="server" ID="TEL_DP_EntryDate" TabIndex="4"  Enabled="False" Culture="en-US" >
<Calendar UseRowHeadersAsSelectors="False" UseColumnHeadersAsSelectors="False" ViewSelectorText="x">
</
Calendar>
<DateInput TabIndex="4" DisplayDateFormat="M/d/yyyy" DateFormat="M/d/yyyy" LabelWidth=""
 EnableSingleInputRendering="False">
</
DateInput>
<DatePopupButton CssClass="rcCalPopup rcDisabled" ImageUrl="" HoverImageUrl="" TabIndex="4">
</
DatePopupButton>
</
telerik:RadDatePicker>


The issue remains IE8

Hello Ricardo,

The presented behaviour could appear mainly in two cases.
The first one is actually a bug in the IE browser which leads to the presented issue. Every Internet Explorer version (except IE10) on the other hand has the limit of loading only 31! stylesheets per file and thus fails to load all CSS files in a theme if they are more than 31. More information on this matter could be found in the blog post bellow:
http://blogs.telerik.com/blogs/posts/10-05-03/internet-explorer-css-limits.aspx
You could try using RadStyleSheetManager on the page in order to combine these stylesheets into one request and see if this helps.

Another possible cause of the presented issue is in case you are showing the RadDatePicker control with ajax request. In case you have ajax on the page I would suggest you to disable it and verify if the same behaviour appear. If this is the issue you could use again RadStyleSheetManager on the page and register the Calendar component as a skinnable control like this:
protected void Page_Load(object sender, EventArgs e) 
   
       RadStyleSheetManager1.RegisterSkinnableControl(RadDatePicker1.Calendar); 
    }

I hope this helps. Do not hesitate to contact us back if further assiatance is needed.

The issue is likely to the number of CSS files IE8 can handle.
When I look in detail on the number of CSS files I got 27.

Then when I bring a control form I got more that 31 CSS files.
I'm using the theme "Black"

ASPX file:

<telerik:RadSkinManager runat="server" ID="RicoSkinManager"></telerik:RadSkinManager>


CS file OnLoad() :

RicoSkinManager.Skin = "Black";

This page call the control control.ascx where the RadDatePicker is located.
I tried to use the solution you mentioned but it does not have that method
RegisterSkinnableControl(RadDatePicker1.Calendar);

Hello Ricardo,

Have tried to place RadStyleSheetManager with "EnableStyleSheetCombine" property set to "true" on the top of the page? Note that the RadStyleSheetManager is the control required for combining the styles into one request and not RadSkinManager as you tried. Also note that "RegisterSkinnableControl" is also method of RadStyleSheetManager control.
