Deployment problem with 2010-Q3

Hello,

Using VS2005 and version 2010-Q3 (2010.3.1124.20)

After upgrading to 2010-Q3 and re-deploying to production server (Windows Server 2008) I get:

[SecurityException: Request for the permission of type 'System.Web.AspNetHostingPermission, System, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' failed.]

Note that I have the following in my web.config which I used to get round the missing assembly 'System.Web.Extensions, Version=1.0.61025.0 exception. This worked fine with 2010 Q2 but not anymore.

<runtime>

<assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">

<dependentAssembly>

<assemblyIdentity name="System.Web.Extensions" publicKeyToken="31BF3856AD364E35" culture="neutral" />

<bindingRedirect oldVersion="1.0.61025.0" newVersion="3.5.0.0"/>

</dependentAssembly>

</assemblyBinding>

</runtime>

My Windows Server 2008 is out of the box. It does not have System.Web.Extensions version 1.0.61025.0 in the CAC.
Question:
1. Do I need to install ASP.NET AJAX 1.0 ASP.NET AJAX 1.0 ?
2. Where can I find detailed info about what is needed on a production box for it to be able to host a Telerik app.

Note: I created a default Telerik web app using the widzard and I get the same 'System.Web.Extensions, Version=1.0.61025.0 exception on the production box.

Thanks.

Filtering on GridHyperLinkColumn

Hi! I'm getting a SQL Exception error (invalid column name) when trying to filter on a GridHyperLinkColumn. What I'm trying to do is show the name of a person in the column with a hyperlink to the person's email address.

Here's the code from the aspx page:

<telerik:GridHyperLinkColumn DataNavigateUrlFields="Email1" UniqueName="Email1"



DataNavigateUrlFormatString

="mailto:{0}" DataTextField="Name"
HeaderText="Reviewer" SortExpression="Email1" ShowFilterIcon="false"



ShowSortIcon

="false" AutoPostBackOnFilter="true" />

The stored procedure which populates the radgrid does pull back column names "Name" and "Email1". The radgrid appears to display correctly in that I do see the names of people and if I click on one of the names my mail client does open up an email window with the person's name in the "To:" field.

However, when I attempt to filter on the column I receive the following error (regardless of whether I type in a person's name or email address:

System.Web.HttpUnhandledException: 
Exception of type 'System.Web.HttpUnhandledException' was thrown. 
---> System.Data.SqlClient.SqlException: Invalid column name 'Name'.

Is it possible to do this type of functionality GridHyperLink column where the data displayed comes from one column in a database table but the hyperlink ability uses another column in the database?

Thanks!

DataFormatString and FooterText problem

Hello.

I've got a bit of problem. If I declare a column in a grid with a specific DataFormatString, then create an aggregate of it with FooterText, the text does not show up. So this code snippet below

<telerik:GridBoundColumn HeaderText="Column1" SortExpression="Column1"

DataField="Column1" UniqueName="Column1" DataType="System.Decimal"

DataFormatString="{0:$###,##0.00}" Aggregate="Sum" ItemStyle-Wrap="true" HeaderStyle-Wrap="false"

FooterText="Total Column1: ">

<ItemStyle HorizontalAlign="Right" Wrap="True" />

<FooterStyle HorizontalAlign="Right" Wrap="True" />

</telerik:GridBoundColumn>

would show the column with currency format but the will not show the right footer text. However, once I remove the DataFormatString setting, the footer text displays. However, I need to have the currency formatting in place. Is there a better way for me to do this, or are we not allowed to do this?

Thanks,
Ernest

Expand to Single Node when using DataBind()?

Currently all my data is being bound through a custom Hierarchy class, I'm having a bit of trouble expanding the structure to make the node I want visible... well... visible. I attempted to use MyTreeView.Nodes(MyIndex).Expanded = True directly after calling MyTreeView.DataBind() but it keeps telling me the index is out of range... but I'm fairly certain it is not. How would one go about expanding a single node of a TreeView without building it from scratch node by node.

* My Bad, I forgot the Node structure was recursive. So I really needed to be working off MyTreeView.Nodes(0). I worked up a little code to get the results I needed, where "selected" is a string value for the text associated with the node I want to expand to:

    Dim Node as RadTreeNode
    Node = rtvHierarchy.FindNodeByText(selected)
    Node.Selected = True
    Node = Node.ParentNode
    do while not (Node is Nothing)
      Node.Expanded = True
      Node = Node.ParentNode
    loop

GridView DetailTable display problem with IE 8

I am using the 2010 Q2 controls and am not able to get multiple DetailTables (GridTableView) to display under the same master table. There are two detail tables in the hierarchy under the same master, and the second table appears to be displayed on top of the first one (text bleeds through). This is not a problem in Firefox, only IE.

ListView with more than 3 columns

I'm using the sample you provided for RadListView with the following code

<telerik:RadListView ID="listViewProducts" runat="server"

onneeddatasource="listViewProducts_NeedDataSource" ItemPlaceholderID="ProductsHolder"

DataKeyNames="ProductCatalogID" Width="1200px">

<AlternatingItemTemplate>

<div class="rlvA" style="height: 150px; width: 220px; margin-top: 5px; margin-left: 5px;

margin-right: 5px; margin-bottom: 5px; padding-left: 15px;">

<asp:Panel ID="pnl" runat="server" Width="220px" CssClass="header4" >

<b> <%#Eval("Products")%></b>

<div style="padding-left:20px;padding-top:20px;" >

<asp:ImageButton ID="ImageButton1" ImageUrl="~/Images/Product.jpg" PostBackUrl='<%# Eval("Link")%>' runat="server" />

</div>

</asp:Panel>

</div>

</AlternatingItemTemplate>

<ItemTemplate>

<div class="rlvI" style="height: 150px; width: 220px; margin-top: 5px; margin-left: 5px;

margin-right: 5px; margin-bottom: 5px; padding-left: 15px;">

<asp:Panel ID="pnl" runat="server" Width="220px" CssClass="header4">

<b><%#Eval("Products")%></b>

<div style="padding-left:20px;" >

<asp:ImageButton ID="btnSample" ImageUrl="~/Images/Product.jpg" PostBackUrl='<%# Eval("Link")%>' runat="server" />

</div>

</asp:Panel>

</div>

</ItemTemplate>

<EmptyDataTemplate>

<div class="RadListView RadListView_Windows7">

<div class="rlvEmpty">

There are no items to be displayed.</div>

</div>

</EmptyDataTemplate>

<LayoutTemplate>

<div class="RadListView RadListViewFloated RadListView_Windows7">

<div class="rlvFloated rlvAutoScroll">

<div id="ProductsHolder" runat="server">

</div>

<telerik:RadDataPager ID="RadDataPager1" runat="server" PageSize="7">

<Fields>

<telerik:RadDataPagerButtonField FieldType="Numeric" />

</Fields>

</telerik:RadDataPager>

</div>

</LayoutTemplate>

</telerik:RadListView>

There are a few issues:
1. I cannot see the "Open Layout Editor" in design time
2. How can I make the result show more than 3 columns? It seems the definition is in your Telerik css that I don't have access to.
3. The DataPager is not working.

Thanks for your help.

Client time optimization to download a page with and without cache

I checked the loading time of a RadWindow through firebug with and without cache (see Screenshots) and I noticed that the css and the images are downloaded for each opening, even with the cache enabled.

How can I optimize the calls to the server by uploading the css and images from browser cache without checking if they have been modified?

You can perform some other optimization to reduce the loading time?

HtmlEncode for GridHyperLinkColumn

Hi, Is there any way to configure a GridHyperLinkColumn to HtmlEncode the contents of the DataTextField? Unlike the GridBoundColumn, it doesn't appear to have an HtmlEncode property. What's more, because HyperLink columns don't support databinding, I can't add encoding that way either. The only option I can see is to change the column type to a template column but I'd rather avoid that if possible.
