Telerik.web references having errors in a .net web form application

I am getting the following error, "The following assembly has dependencies on a version of the .NET Framework that is higher than the target and might not load correctly during runtime causing a failure: Telerik.Web.Design, Version=2018.1.117.40, Culture=neutral, PublicKeyToken=121fae78165ba3d4. The dependencies are: System.Windows.Forms, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089. You should either ensure that the dependent assembly is correct for the target framework, or ensure that the target framework you are addressing is that of the dependent assembly"
for the following Telerik items: Telerik.Web.design, Telerik.Web.UI, and Telerik.Web.Design twice.

I am using Visual Studio 2010 and pointing to the BIN 4.0 folder for the Telerik references. I get these messages if I use the 2018 or 2019 Telerik updates.

In the last few months, I have installed visual studio 2012 on my workstation for another .net 2012 application that does not use the Telerik tool.

To solve my problem, I am wondering if I should do one of the following:
1. Uninstall visual studio 2012 from my workstation. I do not need this version for the application I was looking at previously.
2. Upgrade my visual studio 2010 .net application to visual studio 2012. However I do not know if I will have upgrade issues with that code.
3. Would you tell me what you suggest that I do?

Client-bound grid, DateTimeColumn showing different data depending on user's clock settings

I believe this is a bug since it is causing unexpected results.

I have a grid which is bound client-side to a web service. It would appear that datetime columns are being displayed differently, depending on the user's clock settings. In my scenario, my grid has two such columns (declared below).

<telerik:GridDateTimeColumn HeaderText="Svc. Date" DataField="ServiceDate" DataType="System.DateTime" DataFormatString="{0:MM/dd/yy}" AllowFiltering="false">
<HeaderStyle width="80px" HorizontalAlign="Left" BorderStyle="None"></HeaderStyle>
</telerik:GridDateTimeColumn>
<telerik:GridDateTimeColumn HeaderText="Created When" DataField="CreatedWhen" DataType="System.DateTime" DataFormatString="{0:MM/dd/yy hh:mm:ss tt}" AllowFiltering="false">
<HeaderStyle width="140px" HorizontalAlign="Left" BorderStyle="None"></HeaderStyle>
</telerik:GridDateTimeColumn>

For users who are in the Central US timezone, the "ServiceDate" column is showing as one day earlier, and the "CreatedWhen" column is showing as one hour earlier. When they switch their computer clock to Eastern Timezone (the correct zone for the data being retrieved), then the ServiceDate and CreatedWhen columns appear correctly.

Looking at the json being used to bind the grid to, for one row, these are the values being retrieved from the database...

"ServiceDate":"\/Date(1508904000000)\/", "CreatedWhen":"\/Date(1508942284530)\/"

So, it appears whatever mechanism the grid is using to convert these date objects to date literals is using the user's computer settings. Is this true?

I'm not sure this is a good implementation. The data being retrieved from the database is intended to be displayed as is. Any manipulations to customize for user timezone should be handled by the developer. After all, the grid does not know what timezone the data being retrieved is in, so how does it know how to convert to the user's local machine timezone?

In this case, the data being retreived was in Eastern US timezone. So, a date of '10/24/17', for instance, was being displayed as '10/23/17' (one hour earlier than 10/24/17 00:00:00, assumedly)

So, is there any way to prevent this behavior?

Create RadSocialShare control client-side

ASP.NET version: 4.0.30319
OS: Windows Server 2012 R2
Browser: Google Chrome v66.0.3359.139 (Official Build) (64-bit)
Exact Telerik Version: 2014.1.225.40 (2007-2014 Telerik AD)
Preferred programming language: VB.NET

Hello, I'm currently implementing infinite scroll/load more functionality for news articles on our website. Do you have any documentation or advice on how we can initialize the RadSocialShare control client-side? I can load the initial batch of articles with their respective RadSocialShare controls, but because we're adding load more, we don't have the title and url to share until the user scrolls to the bottom of the page. Is there a way to find out which components we need in order to wire up RadSocialShare controls for the subsequent batches of articles?

Thanks!

[Solved] Passing a rowindex to javascript function from Hyperlink

I have a hyperlink within a Radgrid which opens up a RadWindow for the user.

<telerik:GridTemplateColumn HeaderText="Id" ReadOnly="true" SortExpression="Lookup" UniqueName="Lookup">
<ItemTemplate>
<asp:HyperLink ID="hlWorkOrderId" Text='<%#Eval("Lookup")%>' NavigateUrl='<%#String.Format("javascript:openWindow({0});", Eval("WorkOrderId"))%>' Enabled='<%#String.IsNullOrEmpty(CurrentUser).Equals(False).ToString%>' runat="server" />
</ItemTemplate>
</telerik:GridTemplateColumn>

The user is requesting that when they click on the hyperlink, they want that row in the grid highlighted. How can I pass the selected row index to the javascript function in the Hyperlink?

ImageButton viewImageButton = attachmentsGrid.MasterTableView.FindControl("DownloadForShot_ImageButton");

viewImageButton.Attributes.Add("onclick", " ExportButtonClick ();");

}

Disabling all Telerik Controls on Single Page at Once

Is there a way to use only a single command to disable all the telerik controls on a singe page in one command?

If there isn't, they can still be disabled individually, but it is a nice time saving trick if there is.

Note that we have found tutorials that describe how to individually make telerik controls read only, through programming code. (Here is a good example: http://www.telerik.com/forums/programmatically-enabling-disabling-grid-row-editing)
