I'm getting the following javascript error on a page when clicking an ajaxified button after upgrading to Visual Studio 2010 and ASP.Net 4.0:

No code changes have been made to the page and it was working fine under .Net 3.5.  We are on version 2011.1.413.35 of the Telerik controls.

 
EDIT:

I tried serveral different things to get this to work with little success.  As a last attempt I upgraded to the latest version of the Telerik controls, 2011.2.915.40.  When I upgraded I noticed that it was referencing the 3.5 framework version of the dll instead of the 4.0 version.  I manually changed this and retested - it now works again.  Unfortunately, I have to regression test my site due to the Telerik upgrade but we are already in the process of doing this with the 4.0 migration, so it could be worse.

We would like to keep the height to "auto", rather than having to set the height manually.  This only happens in Internet Explorer 9.  The auto height works fine in all other versions of Internet Explorer, and does not show the scrollbars.  Does Telerik have a fix for this?

<telerik:RadDock ID="RadDock1" runat="server" Width="720px" BorderStyle="None" Skin="MySkin1"
EnableEmbeddedSkins="False" EnableRoundedCorners="True"
EnableAnimation="True" Title="RadDock1"
DefaultCommands="ExpandCollapse" Collapsed="True" Visible="False">

(skin)
.RadDock .rdTop .rdTitleBar
{
  text-align: left;
  position: relative;
  vertical-align:top  !important;
}
.RadDock
{
  height: auto!important;
  margin: 0 0 15px 0 !important;
}

Hi, so I have a radgrid in the nestedviewtemplate of another radgrid.  It works fine, except I don't know how to add validation to the Edit template for it when someone clicks to edit one of the rows.  Client side validation controls apply to every row that has it open, and I have no idea how to access it's "Add New Record" event.

any ideas?

Thanks

Hello,

I have searched through the forums and either not found a solution that solves my problem, or was unable to get it to function how I wanted.

I have a set of data that looks like this:

Item#        Item edition date        last updated date
123            12/1/2010                    6/1/2011
123            11/1/2010                    2/1/2011
123            2/2/2010                      3/1/2010
555            6/30/2011                    7/5/2011
555            4/1/2011                      5/1/2011
666            1/1/2010                      12/31/2010
666            10/1/2009                    12/31/2009


I would like to group the data by the Item#, which I can do, but then I want the groups sorted by the last updated date only, which I cant do. The SQL I use to get the data performs the grouping and sorting correctly, but its not reflected when I bind it. I am using AdvancedDatabinding as well.

Any suggestions/help?

Hi:

I am getting a blank screen.

Hi, 
I am using RadGrid and I have  added the  scriptmanager to the page from code, making sure that the  first control on the  form is  always a scriptmanager. However, while loading the  page it works fine but  on postback it  throws the  error "Script Control may not be  registered before prerender". 

 Stack Trace: 

[InvalidOperationException: Script controls may not be registered before PreRender.]

I have  used the  control as follows.

 Could you guide me as how I could  handle this exception. 

Thanks in Advance.

Hi, I am using XmlDataSource with RadGrid. I need to use Column's Aggregate functionality to show sum (in footer) in one column. As datasource is XML, grid considers I have all string data even though I have numbers in the column. How can I use Sum Aggregate functionality with Xml data source?

code sample:
<asp:XmlDataSource ID="XmlDataSource1" runat="server" DataFile="~/App_Data/data.xml"  XPath="/root/Row"></asp:XmlDataSource>
<telerik:RadGrid ID="RadGrid1" runat="server" DataSourceID="XmlDataSource1" ShowFooter="true">
    <MasterTableView AutoGenerateColumns="False" DataSourceID="XmlDataSource1">
        <Columns>
          <telerik:GridBoundColumn DataField="col1" HeaderText="Product" SortExpression="col1" Aggregate="Count" ...

Thank you,
Amit Vaishnav
