RadDatePicker howto stop Autopostback in some cases

I have a Grid with a lot of rows and a different DateTime value on each row. When I mouse hover the rows I set the selectedDate of an outside RadDatePicker client-side using the javascript set_selectedDate().
When the user opens the calendar popup and selects a different date a server side event is fired and the grid is updated with AJAX.

The problem is that the client javasript set_seletedDate method also fires the server side event because of the Autopostback, but I want the server event fired only when the date is changed using the popup.
If I set Autopostback to False then the server event never gets fired..

How can I cancel the server postback after I call set_selectedDate() and make the popup selecteddatechanged server event keep working?

Is it possible to update a radbutton background which is on a radgrid row, without rebinding the entire radgrid?

I have a radgrid that takes 20 + seconds to databind.

Each row has a button with databound command argument

<telerik:GridTemplateColumn DataField="EnableScript" HeaderText="EnablScript" UniqueName="EnableScript">
<ItemTemplate>
<telerik:RadButton ID="EnableButton" runat="server" CommandArgument='<%#Eval("EnableScript")%>' Text="Enable poller" OnClick="EnableButton_Click"/>
</ItemTemplate>
</telerik:GridTemplateColumn>

Is it possible to update the radbutton background per radgrid row, without rebinding the entire radgrid?

Grtz,

RadGrid - Reuse for different datasets; and have filters showing data.

(If this is the wrong section to post into, please advise and I'll repost in the proper spot.)

So I need some assistance as I have an idea of what I need, but putting it into code is the challenge. (Or pseudo code).

a) Can't I utilize the RadGrid object with different datasets depending on the 'dropdown box' selections?

b) Can't I bind the data, dynamically display headers, AND, have the dataset fields data grouped into filters?

I'm challenged, that I need different RadGrids for different datasets.

(Read between the lines, my engineer is saying it's difficult; but my experience with Telerik isn't noob, thus it doesn't sound difficult.)

Pass Multiple Parameters to RadWindow after Cell Double Click

Hello,

I am trying to pass two parameters (Red and Blue outlined in attachment) to a radWindow via a Cell double click, which I will then populate a grid. I am able to pass the datakey (Red outlined) value on row double click thanks to this demo, but have had no luck in capturing the Column name to use in the querystring.

Is there a Cell Double click event that I can use to make this happen or can this be done with Row Double click that captures the cell index I click on?

The second attachment shows the window opened based on the demo link, but how can I get the querystring URL to show:

Bklg_SupportStatusWIPDetails.aspx?MPC=ABAL1TC7XB00?AREA=DB

where Area is another parameter in my datasource that is looking for the column name.

Thank you in advance!

Can application still use 2016 Telerik ASP.NET UI ASO.NET_AJAX download

To run a vb.net 2010 web form application, I have previously used Telerik ASP.NET UI ASO.NET_AJAX_2016 Dev.msi download files so the application would run successfully.
In the past I have found out that if I do not have the current Telerik tool installed, the application had unpredictable results. Basically when the .net application ran on the test application server, I got errors when I accessed the Telerik tool contained within the .net application. Is this still the same issue? Can I continue to use the version of the Telerik tool the application is accessing currently ? If so, can you tell me how long I can continue to use the same version of the Telerik tool?

If not, can you tell me what version of the Telerik tool I need to install?
**I am asking this question since I do not know if my latest install of the Telerik ASP.NET UI ASO.NET_AJAX_2017_1_228_Dev.msi installed correctly.

Safari bug?

We have a user using Safari 3.1 (on Mac OS X 10.4) who reports that when he clicks on the RadComboBox nothing happens. The combobox doesn't drop down as it should. Are there any known issues with RadComboBox and Mac Safari? I am running the latest version of Prometheus on the website. Here is the RadComboBox in my aspx page:

<

telerik:RadComboBox ID="rcbProcessGroup" DataSourceID="dsGetProcessGroups" runat="server" Skin="WebBlue" AppendDataBoundItems="true" Font-Size="12px" AutoPostBack="true" DataTextField="ProcGroupName" DataValueField="PgrpID" Width="196px">
