I'm attempting to use my first RadHtmlChart (pie chart).  The SqlDataSource provides the following:

+---------------------------+--------------------+

|              stat              |    StatCount    |

+---------------------------+--------------------+
|Closed                       |         4067        | 

+---------------------------+--------------------+
|Pending Assignment |           1            |

+---------------------------+--------------------+
|QA Ready                 |       600            | 

+---------------------------+--------------------+
|In QA                        |       400             |

+---------------------------+--------------------+
|Assigned                  |      4946            |

+---------------------------+--------------------+

The RadHtmlChart:

Error message:

Cannot create an object of type 'System.Nullable`1[[System.Decimal, mscorlib, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089]]' from its string representation 'StatCount' for the 'Y' property.

What am I doing incorrectly?

Thanks,

I create Sharepoint 2013, and deploy it in Sharepoint Farm Enterprise, all running well with Administrator user privileged, but when I access page with my webpart in it, with general user, it come with error

"Sorry, this list hasn't been shared with you. "

In debug mode (I build with VS 2017 in server environtment) it have same behaviour

I use RadAjaxLoadingPanel component, RadTabStrip component, RadMultiPage component, RadPageView component, RadScheduler Component, RadTooltip component

Could you assist me with this permission error? any limitation on Telerik Scheduler in my WebPart?

I have various different data sets that I get from one of my VB.NET WebAPI's. My WebAPI is a separate project that feeds a lot of JSON to another client-side project with my Grid.

I wanted to be able to have users select which data set they want to see, such as "Due Dates" or "Books" or "Memberships" and have each different option show a different RadGrid, while only ever including one RadGrid in my ASPX. I first thought to try UserControls, each with its own grid and binding logic, but I never got them working.

Is it possible for me to just have one RadGrid defined in my ASPX and then have it be fed data and how to display that data from my WebAPI on-demand? I would somehow need it to know how to size certain columns, how to have different item templates, how to have different sorting, etc. I effectively just don't want 10 different RadGrid controls on one page, and I want them all to be fed via my WebAPI and have as little code-behind in the grid's project as possible.

How set default time like "00:12:00" in RadDateTimePicker?

I have set TimePopupButton-Visible="false" and only want to select the date...

Hi,

could somebody help me with my issue ? I have radtextbox with TextMode="SingleLine". This textbox awaits user's scanned barcode with enter key as last char. Then I process input text in OnValueChanged client side event. So far so good. The problem has appeared when input text is longer then radtextbox width. The situation is shown in attachment.

The question is, how to style single line radtexbox so it will look like multiline (increase height and wrap text), but still acts as SingleLine, e.g. on enter key press no new row will be added, just OnValueChanged event should rise...

Thank you

Best regards

I have a ascx control that contains a popup radWindow which contains a datalist that is populated at the time the ascx is loaded on the page.  A button displays the radWindow with the preloaded values in a template, which contains an editable textbox on each row.  When the window is hidden, the textbox values should persist in the hidden window until the Save button on the main page is pressed saving the entire page, plus the values in the hidden radWindow.

When I load the page, and open the radWindow for the first time, the previously saved values are displayed in their respective textboxes.  If I then press OK to hide the window, then immediately reopen it, the values in the VISIBLE textbox are gone.  The values in the label control and the HIDDEN textbox are retained.

If when I open the window for the first time with the original values present, then change any one of the visible text boxes, then close and immediately reopen, all my values are retained, including the preloaded values plus any edits.  I can now open and close as many times as I want without changing any data values and not lose any values in the visible textboxes.

If I change the hidden textbox to visible, it also loses its values as in the above scenario.  If I change the visible textbox to hidden, it retains its values in all scenarios.  The label in the <itemtemplate> doesn't seem to be affected.  

If I navigate to the page, which prepopulates the datalist in the radWindow, and DO NOT open the window, then press save on the main page, I also lose the values in the Visible Textbox.

So, it appears that when a textbox is visible in the window, it does not persist its values, unless something has changed.  Not sure why it will show the values when the window opens for the first time and not show them on any subsequent open.  I have tweaked several settings on the radWindow control to no avail.  This is happening in multiple browsers (Chrome, IE, Edge), so not isolated to browser type.  I am curious what is triggered when a value is changed to suddenly persist the values in the VISIBLE text boxes, why the textboxes do not seem to have persisted values when they are visible, regardless if the window is opened or not.

I converted this from another third-party window control and it worked perfectly.  Since we are now using Telerik, it necessitated the change. The only changes I made to the sourcecode was the javascript function that opens the radWindow in the 'onclick' event and  the <telerik:windowmanager> tag, down the to the <ContentTemplate> wrapper tags.  Everything contained between the ContentTemplate tags is exactly the same, essentially reproducing the previous window controls behavior, with the exception of this issue.

Thoughts?!?

Button that opens the window: 

<input type="button" class="command_button" value="..." onclick="javascript: window.radopen(null, 'radPreWin');" />

Window:

            </telerik:RadWindow>
        </Windows>
    </telerik:RadWindowManager>

Javascript function that hides the window when "OK" is pressed:

           function WindowClose()
            {
                var oWindow = $find("<%= radPreWin.ClientID %>");
                oWindow.hide();
            }

Right now, I am working in administration dashboard. Inside dashboard there is a left side menu which can be expanded or can be collapsed.Let me show you its code,

So as you could see there is some hard coded <ul> and <li>s out there and I need to replace it's content and those content will be populated from database.

Please run snippet to view content which will be shown in place of hard coded content as shown below,

Now, I wanna know If I could get desired output using RadPanelBar control?

Note:- What I am getting If I'm using RadPanelBar control..

Usually I use the MVC components, and understand that grid really well, but this is the first time using this version of the grid (UI for APS.NET AJAX), and am not familiar with it at all.  I have the option of AllowAutoUpdates marked as true, but when I click the edit link, the form that displays for editing really looks bad.  The form field captions all seem to be aligned to the left, but the form fields are way over to the right.  How can I make this look better?

Hi There,

I have come back to a system I coded 2 years ago. The code worked fine when I last worked on the web app but now I am getting the attached errors.

Does anyone have any ideas why I'm getting these errors.

Thanks for your help.

Best Regards,

Steve.
