Default sort order?

Hey,

Trying to make a grid sort a column in descending order after clicking once on the header instead of the default ascending first. Essentially, the behaviour of this demo. From this documentation I get the impression that I can just do this from markup, as the demo does it by creating a SortExpression from code behind. I tried this in my code, and I'm not seeing a behaviour difference.

It's for Telerik 2010Q2 release, without the service pack.
VS2010, .NET 4.

The relevant grid markup follows. It pulls from a LinqDataSource, declared by DataSourceID.

<MasterTableView DataKeyNames="ReportID">

<SortExpressions>

<telerik:GridSortExpression FieldName="ReportSeverityLevelID" SortOrder="Descending" />

<telerik:GridSortExpression FieldName="ReportSeverityColumn" SortOrder="Descending" />

</SortExpressions>

<Columns>

<telerik:GridTemplateColumn HeaderText="Severity" HeaderStyle-Width="45px" SortExpression="ReportSeverityLevelID" UniqueName="ReportSeverityColumn" AllowFiltering="false">

<ItemTemplate>

<asp:Image ID="Image3" runat="server"

ImageUrl='<%# string.Format("~/Images/{0}", ReportSeverityLevel.GetReportSeverityLevel(r=>r.ReportSeverityLevelID==(int)Eval("ReportSeverityLevelID"),r=>r.IconImageFile)) %>' ImageAlign="AbsMiddle"

AlternateText='<%# ReportSeverityLevel.GetReportSeverityLevel(r=>r.ReportSeverityLevelID==(int)Eval("ReportSeverityLevelID"),r=>r.Name) %>' ToolTip='<%# ReportSeverityLevel.GetReportSeverityLevel(r=>r.ReportSeverityLevelID==(int)Eval("ReportSeverityLevelID"),r=>r.Name) %>' />

</ItemTemplate>

</telerik:GridTemplateColumn>

Not, I tried the sort expression by column name just in case, as the documentation suggests it should be by the DataSource field, which the first SortExpression for FieldName ReportSeverityLevelID is.

Thanks for any ideas.

How To Databind LightBox ItemTemplate

I have a lightbox setup with an ItemTemplate, I am displaying html text (not images like the data binding examples). I have an asp.net label inside my ItemTemplate that I want to bind the lightbox control to a list of strings and show the string inside of the label. I tried <%# Eval("mypropname")%> inside of the label but get a "Value of type 'System.Web.UI.Control' cannot be converted to 'Telerik.Web.UI.RadLightBoxItem'.

All of the Data* properties exposed server side appear to be specific to displaying images in lightbox. Is there a way to databind a lightbox with a custom item template to a list of strings? If not, is there a way to manually add these items to the lightbox server side?

Thanks!

Render RadDropdownlist from C# code behind

Hello

Current Scenario: Currently we are generating html select (dropdown) from code behind using string builder and adding the generated HTML into literal control - which will display the HTML. Below is the code snippet.

html.Append("<select name=test id=test class='xyz' onchange=\"changeDD(this);\" >");
html.Append("<option value='1'>xyz</option>");

We have number of controls being rendered dynamically based on customer settings. Now, We are trying to replace this html select (dropdown) with Telerik RadDropdownlist.

Please suggest the approach or provide your inputs to achieve this kind of HTML rendering from code behind. Also we have JS written for some of the controls.

Please let me know if you need more details.

ImageEditor - ViewPaths

Hello,

I have this mark up in my code.

<tlrk:RadEditor ID="D0_RadArticle" runat ="server" Width="680px" Height="376px"

ToolsFile="~/XML/Editor/HelpEditor.xml" ImageManager-ViewPaths="~/Images/Help"

AnchorPathToStrip="ihs201" StripAbsoluteAnchorPaths="true" />

The client is able to select an image and store it to the database. The link that is stored is <img alt="" src="/ihs201/Images/Help/Editor/underline.jpg" />. This is fine when I am in my development server. But when I deploy my web pages to a different server I do not want the "/ihs201" in my link. If the virtual directory name is different then "ihs201" then the images link breaks. I would rather my link was <img alt="" src="../Images/Help/Editor/underline.jpg" /> . This link would enable me to access the image in other server with different name. How do I achieve something like that.

Thank you,
Kalyani

Microsoft jscript runtime error Parameter name: panelsCreated[0]

I am not sure which control this error should be mapped to.
I have an asp.net wizard and the wizard pages come from user controls. On some of those pages I have a radgrid.
On one of the page I have a chart and the next page after that is the one that has radgrid. I get the error Microsoft jscript runtime error Parameter name: panelsCreated[0] and the chart does not load for me. If I use asp.net grid instead of radgrid on that page then everything works fine.

Below is the ascx page that has the radgrid.

<%@ Control Language="c#" Inherits="ucBBucket" CodeFile="ucBBucket.ascx.cs" %>

<asp:ScriptManagerProxy ID="ScriptManagerProxy1" runat="server">
