Q3 2011 (Version number: 2011.3.1115)

Problem: When adding items to OData-enabled controls (RadMenu, RadTreeView, RadListBox, RadComboBox) through design time erroneous markup is applied to the control:

<telerik:RadListBox runat="server" ID="RadListBox1">
    <Items>
    </Items>
    <WebServiceSettings>
        <ODataSettings InitialContainerName="">
        </ODataSettings>
    </WebServiceSettings>
</telerik:RadListBox>

Please note the added ODataSettings section. It will cause JavaScript errors on the page.

When I run my project I'm getting this error

Could not load file or assembly 'Telerik.Web.UI' or one of its dependencies. The located assembly's manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040)

In my web.config I checked that the version in the web.config is the same as the version I'm using in references

<assemblyIdentity name="Telerik.Web.UI" publicKeyToken="121fae78165ba3d4" culture="neutral" />
        <bindingRedirect oldVersion="0.0.0.0-2020.2.617.45" newVersion="2020.2.617.45" />

Recently I've been expressing some weird behavior with the MultiSelect displaying and extra dropdown next to the control (see attached image).  This is just standard markup, nothing fancy. Is there a property setting I'm missing? 

Thanks for any help you can provide.

<telerik:RadMultiSelect ID="msLOB" runat="server" Width="100%" Filter="StartsWith" Placeholder="Select LOB" DataTextField="text" DataValueField="value" Skin="Silk" RenderMode="Lightweight">
    <Items>
       <telerik:MultiSelectItem Text="All" Value="All" Selected="false"></telerik:MultiSelectItem>
       <telerik:MultiSelectItem Text="Commercial-Large" Value="Commercial-Large" Selected="false"</telerik:MultiSelectItem>
       <telerik:MultiSelectItem Text="Commercial-Small" Value="Commercial-Small" Selected="false"></telerik:MultiSelectItem> 
        <telerik:MultiSelectItem Text="Commercial-Individual" Value="Commercial-Individual" Selected="false"> 
        </telerik:MultiSelectItem>
       <telerik:MultiSelectItem Text="Medicare-MAPD" Value="Medicare-MAPD" Selected="false"></telerik:MultiSelectItem>
  </Items>
</telerik:RadMultiSelect>

This demo doesnt work - is there a working version?

Hi,

I have an HTML form and a RadGrid configured on a page. RadGrid's events and all the properties are dynamically built on the server side. RadGrid has an ExportToExcel toolbar command and works as it is. The issue is when I click the ExportToExcel toolbar button, It downloads the Excel file. When I click the HTML form's Save button, which means input type submit button, Radgrid downloads the Excel file again. If I click a different Radgrid toolbar command and then click the Form submit button, Radgrid will trigger its previous toolbar event.

Thanks

Is it possible in radgrid to allow a collapsed group to be selected by row and then drag and drop to new grid and all the collapsed rows under the group are dropped?

Hi,

I'm testing the PDF Signature demo shown in this Telerik example PDF Signature demo. The issue I'm having is I cannot pull a pdf that resides on a network file server where we store all common files. I have no issues loading a pdf on my localhost machine. 

From what I can tell, the issue appears to be the third party opensource pdf.js file Telerik is using in demo that seems confined to only load pdf's from directories within the web application and it's sub-folders defined in IIS for the website. Also, the network file server is used everywhere within our web application so it's not a security issue. 

The error I get from pdf.js is "Not allowed to load local resource" which results in page prompt "PDF file fails to process." display. 

We have an existing web.config entry that looks like this:

<add key="AttachmentsShare" value="\\my_file_server\file"/>

I've tried calling the file server a few different ways with no luck.

RadPdfViewer1.PdfjsProcessingSettings.File = ConfigurationManager.AppSettings("AttachmentsShare") & "1234.pdf"

RadPdfViewer1.PdfjsProcessingSettings.FileSettings.Url = ConfigurationManager.AppSettings("AttachmentsShare") & "1234.pdf"

Please advise. Thanks.
