Hello Telerik team,

I have a weird problem with the datepickers on the production site.

Since I migrated the Telerik.Web.UI.DLL, Telerik.Web.UI.Skins.DLL and Telerik.Web.Design.DLL from 2014.3.1002.40 to 2016.1.322.40 the popups of my datepicker, datetimepicker, Timepicker and MonthYearpicker don't work anymore on my costumers website. The page flickers somewhat when clicking the control and the horizontal scrollbars appears shortly at the bottom of the browsers window but that's it. In my own Visual Studio environment all's working well. If I migrate back to the previous DLL's it's working again.

I can't find out where the problem lies, I've checked everything (I think). Do you have any clue?

Many thanks,

Geert Jansen

CSS for RadGrid & RadMenu

I have a RadMenu for our application navigation, with css styles to show what item you are on for any given page. This works perfectly fine until I am on a page with a RadGrid included. If I set EnableEmbeddedBaseStylesheet="false" then the RadMenu shows up fine, but the RadGrid looks HORRIBLE. How can I have the RadMenu and RadGrid both show up as they should?

What controls are used in the left hand Nav on the Telerik Demo pages?

I like the way the left hand nav operates on the Telerik Demo pages (E.g. http://demos.telerik.com/aspnet-ajax/label/overview/defaultcs.aspx). It looks like its built with a SearchBox at the top, a ToggleButton to switch between the currently selected Control and the 'All Controls' menu. Is there a source code example of this anywhere? I like the way the menu slides left and right based on the Toggle Button and wanted to know how this was achieved.

Odd primitive errors showing

A couple of weeks ago, there was an error of an invalid json primitive. From reading about it, it's basically that the json is improperly setup. The error log below seems to trace that to the Rad date picker. However, the only client scripts I am using for that control is resizing it and focusing on the input box. I do not think that would be the problem. What strange is that there is more than 25 errors with this error that happened within a minute from the same IP Address. Could this be a bot or something else?

Error: Invalid JSON primitive: ovAA

Stack Trace:   at System.Web.Script.Serialization.JavaScriptObjectDeserializer.DeserializePrimitiveObject() at System.Web.Script.Serialization.JavaScriptObjectDeserializer.DeserializeInternal(Int32 depth) at System.Web.Script.Serialization.JavaScriptObjectDeserializer.BasicDeserialize(String input, Int32 depthLimit, JavaScriptSerializer serializer) at System.Web.Script.Serialization.JavaScriptSerializer.Deserialize(JavaScriptSerializer serializer, String input, Type type, Int32 depthLimit) at Telerik.Web.UI.RadWebControl.LoadPostData(String postDataKey, NameValueCollection postCollection) at Telerik.Web.UI.RadDatePicker.System.Web.UI.IPostBackDataHandler.LoadPostData(String postDataKey, NameValueCollection postCollection) at System.Web.UI.Page.ProcessPostData(NameValueCollection postData, Boolean fBeforeLoad) at System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint)

Export PDF to server ONLY

Hello,

I am using this method to save a local PDF from a radeditor when a form is submitted: http://blogs.telerik.com/blogs/posts/08-12-08/how-to-export-grid-to-pdf-file-and-show-the-result-using-the-window.aspx

But this sends the PDF to the client as well.

How can I save a PDF to the server without sending a copy to the client?

Grid Grouping and Sorting with ClientDataSource

Hi, I got confused with all the threads I've read and I wasn't able to find an answer to my problem.

I have a RadGrid bound to RadClientDataSource. I'm using ClientItemTemplate to format my data in a single cell and my column does not have a header.

So each data item occupies a single cell per row.

I want to know how I can group/ungroup the grid using a checkbox.

I was able to group by declaring the grouping in the grid but I want to achieve this using the checkbox.

One of the data field in the cell is a date, I want to sort my grid based on this field in a descending order.

How can I do it?

ps. type is string representing the name of the typeid.

<telerik:RadClientDataSource ID="AlarmClientDataSource" runat="server" AutoSync="True">

<ClientEvents OnDataParse="AlarmClientDataSource_OnDataParse" OnChange="AlarmClientDataSource_OnChange" />

<SortExpressions>

<telerik:ClientDataSourceSortExpression FieldName="Created" SortOrder="Desc" />

</SortExpressions>

<Schema DataName="Result" ResponseType="JSON" ErrorsName="ErrorMessage">

<Model ID="ID">

<telerik:ClientDataSourceModelField FieldName="ID" DataType="String" Nullable="true" Editable="False" />

<telerik:ClientDataSourceModelField FieldName="TypeID" DataType="String" Nullable="false" Editable="False" />

<telerik:ClientDataSourceModelField FieldName="Created" DataType="Date" />

</Model>

</Schema>

</telerik:RadClientDataSource>

<telerik:RadCheckBox ID="AlarmGroupCheckBox" runat="server" Text="Group Alarms By Type" Width="100%" RenderMode="Classic"

AutoPostBack="False" OnClientCheckedChanged="AlarmGroupCheckBox_OnClientCheckedChanged">

</telerik:RadCheckBox>

<telerik:RadGrid ID="AlarmGrid" runat="server" ClientDataSourceID="AlarmClientDataSource" Width="100%"

<ClientSettings AllowGroupExpandCollapse="true">

<Selecting CellSelectionMode="SingleCell"></Selecting>

<ClientEvents OnCellSelected="AlarmGrid_CellSelected" OnCellSelecting="AlarmGrid_CellSelecting" OnGridCreated="gridCreated"></ClientEvents>

</ClientSettings>

<SortingSettings SortedBackColor="#FFF6D6" EnableSkinSortStyles="false"></SortingSettings>

<MasterTableView ShowHeader="False" AllowNaturalSort="True">

<%--<SortExpressions>

<telerik:GridSortExpression FieldName="Created" SortOrder="Descending" />

Icons not Showing for custom Skin

Good day Telerik Community,

I'm starting at Telerik and I need help with Custom Skins and web resources for showing Icons.

I have made my custom Skin that is the same as the Old Forest Skin One, it's all good with my DLL until I see Icons ("Edit","Delete","Ok","Cancel", etc.). This Icons are not showing (Html broken Image shown and Alt shown), I want to know how to call the Image from the DLL web resource and not through the File itself (for example: ~/Image/Edit.gif, is what I'm doing now but I want to call it from the Web Resource to keep independance of the Skin).

I hope I'm clear with my trouble I am having,

I hope you can help me Solve it :)...

Thanks for Reading,
