Hello,

I'm following this sample to have the excel-like filtering on my grid view. I'm wondering if I could hide some options in the herder context menu like Group By, Ungroup, and Columns.

 Is there a way?

 

Thanks,

Brew

 

There is a bug in Telerik DatePicker in Windows 10 in certain locales.

Symptom:
UI always selects the current date, whatever date you ​type or pick.
Sometimes this current date is highlighted as invalid, sometimes not (capture attached).

This is most likely related to changes in date parsing:
http://www.heikniemi.net/hardcoded/2015/08/windows-10-breaks-net-date-parsing-in-certain-locales/

I have tested with settings:
DateInput-DateFormat ="dd.MM.yyyy"
Culture ="Finnish (Finland)".

Windows 10 September 30 cumulative update didn't fix the issue.
I have reproduced the problem with the latest version of RadControls.

For those of us who don't want to use the calendar as an input device but only use it for display purposes I'd like to see a compiled control of the input popup that can be used without a scheduler control. For those who want to use it like it is now and customize it etc that functionality can be left in. I'd just like to drag and drop the input on a form set some properties and move on. Having a full blown calendar to input values etc for the idiots I deal with is too much information. Just explaining recurring events is hard enough. Of course this would not be customizable, that's left for what you do now. This is just a down and dirty drag and drop and move on.

Hello,

I have a problem with display and filter by date on the grid (using ajax).

Example:

http://demos.telerik.com/aspnet-mvc/grid/remote-data-binding

My timezone is UTC + 01:00.
If i change timezone on my notebook (-05:00, -08:00, +04:00, +06:00, etc.), all the dates change, and if I filter by date, return ​no data.

I find solution, but it doesn't work well:

Regardless of the change timezone, I need same date (display and filter).

Best regards

 

Is there a way to set a value in the RadRotatorItem that can be used as an asp control parameter in a SqlDataSource?  I have a RadRotator with a client item shown event that I want to fire a repaint of RadHTMLCharts on a page when the Rotator hit's the next item.  I want to be able to specify the value passed to the control parameter.

Hello, i have a few questions.
My scenario is as follows:

I have a MasterPage with AjaxManager. The content page uses AjaxManagerProxy.
In the content page, I have a method that loads controls in a panel.
This method is OK. It loads the controls correctly and i can handle the events inside it normally. The configurations for LoadingPanels also are OK.

My question is about some behaviors I could not identify, and I don't know if there is something I'm missing with configurations or if the behavior is normal and I should handle it other way.

The thing is, the control dynamically loaded contains a RadGrid. When I press a button it loads data in this grid.
Right after that, if I refresh the page (F5) the control is loaded (because of the methods of dynamic loading) but the data on the grid is not there.

Shouldn't the data be there since the ViewState is enabled? I know there is the event NeedDataSource on the grid, I'm handling it already but maybe i'm not seeing something.

I realized something too, when pressing F5 it doesn't behaves like a postback, even after I just pressed a button that executed a postback. I mean, normally when I press a button it runs a postback and if I refresh the page it tries the same postback (prompting onthe browser if I want to repeat that) but in this case it doesn't show.

I would like some help with this. I'll try to shorten the code and post it later.

Thanks

Hi, ​I have an asp button as an updated control ​in an ajax manager.

If a user does not select a proper value in cboDivision, cmdPay is disabled, and when they do select a valid one, cmdPay in enabled. This is all working fine.

When I click the button, it is not submitting the entire page so my interaction with the other controls is not displayed. Am i just not understanding how this works? How can I get the command button to submit the whole page?

 

    <telerik:RadAjaxManager ID="RadAjaxManager" runat="server">
            <AjaxSettings>
                <%--AjaxControlID has to equal its parents name for some stupid reason--%>
                <telerik:AjaxSetting AjaxControlID="cboDivision">
                    <UpdatedControls>
                        <telerik:AjaxUpdatedControl ControlID="cmdPay" />
                    </UpdatedControls>
                </telerik:AjaxSetting>
            </AjaxSettings>
        </telerik:RadAjaxManager>
