VS2019 Options Missing for Converting Project

In previous versions of Visual Studio and the Telerik extension I was able to create a new ASP.Net WebForms application and use the Telerik menu in VS to convert the project. Now in VS2019, the Telerik extension menu is within the new Extensions menu, but I see no options to convert my project.

Am I missing something?

Return of DataValueFields not working

I am trying to get the datavaluefields from the AutoCompleteBox entries and the values are always empty. The text has the text in them but nothing in the value field.

This is the code to make the autocompletebox:

     <asp:SqlDataSource ID="sdsApplications" runat="server" ConnectionString="<%$ ConnectionStrings:ConfiguratorConnection %>" SelectCommand="SELECT Id, Name FROM tblValues" DataSourceMode="DataReader"></asp:SqlDataSource>
     <div class="form-group row label-floating">
      <asp:Label ID="lblApplications" runat="server" CssClass="control-label" AssociatedControlID="racApplications" style="margin-top:0;z-index:99999;">Applications</asp:Label>
      <telerik:RadAutoCompleteBox RenderMode="Lightweight" ID="racApplications" runat="server" Skin="Bootstrap"
       DataSourceID="sdsApplications" DataTextField="Name" DataValueField="Id" EmptyMessage="Select applications to include"
       AllowCustomEntry="False" MaxResultCount="50" DropDownHeight="900px">
      </telerik:RadAutoCompleteBox>

I have never been able to get the values out of the entries on the server side. Can anyone offer a resolution?

Thanks,

David

Export to Pdf does not open in a new window

I have a grid with grouping and scrolling enabled.
On export to pdf the grid is not exported in a new page. instead it loads the data in the grid.
I have the export functionality working as desired on other pages in the app. It gives a prompt to save or open the export. But with the grid I am referring to it does not prompt, just loads the export data into the grid.

I am using the latest Telerik Controls. Pasted below is my grid code:

Treeview rerender after client side events if using load on demand

Hi,

I ran into this issue/weird behaviour. If I setup my treeview to work with load on demand and I perform a client side action e.g. dropping a node into a container, when the action finishes, the treeview will rerender and all my NavigateUrl properties starting with a "/" will have the server address put before them.

This only happens if I use load on demand... If I build a list of objects and set it as my datasource it works fine.

Is there a way to prevent this from happening?

Path traversal vulnerability in RadChart Image Handler

Path traversal in all versions of RadChart for ASP.NET AJAX by Telerik allows a remote attacker to read and delete an image with extension ".BMP",".EXIF",".GIF",".ICON",".JPEG",".PNG",".TIFF", or ".WMF" on the server through a specially crafted request.

Versions prior to Q3 2012 may also be exposed to arbitrary files access within the web application, including the web.config.

To avoid the vulnerability you must remove its HTTP handler from your web.config (its type is Telerik.Web.UI.ChartHttpHandler), e.g.

REMOVE these lines from your web.config file:

<add path="ChartImage.axd" type="Telerik.Web.UI.ChartHttpHandler" verb="*" validate="false" />

and

<add name="ChartImage_axd" path="ChartImage.axd" type="Telerik.Web.UI.ChartHttpHandler" verb="*" preCondition="integratedMode" />

Note: this will prevent the RadChart control from working in your app.

RadChart has been discontinued in 2014 in favor of RadHtmlChart. We advise that you migrate to RadHtmlChart:

RadNumericTextBox to accept only postive integers

Hi

Is there a way for the RadNumericTextBox to accept only postive integers?

I.e:

No negatives
No decimals
No group formatting

I don't know if this is the right approach but for the decimal separator I used "©".

The database stores a 10 digit positive integer.

Kind regards

Mark Eaton
