Populating RadPanelBar with data and set RadPanelItem enable property dynamically

I am populating RadPanelBar from the database. The following is my code. I have a db column that specifies enable true or false. I would like to set the RadPanelItem enable property using this. How can I do this?

Dim dt As New DataTable

dt =GetPanelItems(Id) – proc to call oracle

Dim links As New DataSet()

links.Tables.Add(dt)

RadPanelBar1.DataTextField = "panel_name"

RadPanelBar1.DataNavigateUrlField = ""

RadPanelBar1.DataFieldID = "panel_id"

RadPanelBar1.DataFieldParentID = "Parent_panel_Id"

RadPanelBar1.DataValueField = "panel_value"

RadPanelBar1.DataSource = links

RadPanelBar1.DataBind()
Thanks

How to enter text after a table?

It seems to be impossible to add text after a table, when the table is at the bottom of the document. If I use the arrow or try to click below the table it just selects the table. I want the text to be outside the table underneath it. How can I do that?

thank you

AJAX call never returns

I have a couple of grids on tabs for each row of a grid in a nested view. The code-behind opens the first record to view the first item. At this point, I can click on the link to download my attachment, but it only works the first time. After that, it hangs and I can't figure out why.

If you can figure out what I need to correct, it would be a tremendous help!

I've created a mini-project that demonstrates the problem. I've substituted 2 XML files for data sources, but, for this demo, the attachment is hard-coded. (It's using a PDF.)

<%@ Page Language="C#" %>

<%@ Register assembly="Telerik.Web.UI" namespace="Telerik.Web.UI" tagprefix="telerik" %>

{

ImageButton btnDownload = (ImageButton)sender;

GridDataItem dataItem = (GridDataItem)btnDownload.NamingContainer;

RadGrid Attachments_RadGrid = (RadGrid)dataItem.NamingContainer.NamingContainer;

Label lblShotID =(Label)Attachments_RadGrid.NamingContainer.FindControl("ShotID_Label");

try

{

//NOTE THE HARD CODED VALUE HERE

System.IO.FileInfo file = new System.IO.FileInfo("C:\\inetpub\\wwwroot\\TestSite\\Images\\TestPDF.pdf");

if (file.Exists)

{

Response.ClearContent();

Response.AddHeader("Content-Disposition", string.Format("attachment; filename={0}", file.Name));

Response.AddHeader("Content-Length", file.Length.ToString());

Response.ContentType = "application/pdf"; // "image/jpeg"

Response.TransmitFile(file.FullName);

HttpContext.Current.ApplicationInstance.CompleteRequest();

}

else

{

throw new Exception("There is no attachment for this path or the path is not valid.");

}

catch (Exception ex)

{

Response.Write("<span style='color:red;'>" + ex.Message + "</span>");

}

protected void ShotDetail_RadGrid_PreRender(object sender, EventArgs e)

{

if (!Page.IsPostBack)

{

if (ShotDetail_RadGrid.MasterTableView.Items.Count > 0)

{

ShotDetail_RadGrid.MasterTableView.Items[0].Expanded = true;

ShotDetail_RadGrid.MasterTableView.Items[0].ChildItem.FindControl("InnerContainer").Visible = true;

Not getting any compression!!! Please Help!!!

I have a WCF Data Service in a ASP.NET MVC 3 App on IIS 7. I have configured the web.config to have the following...

<system.webServer>

<validation validateIntegratedModeConfiguration="false" />

<modules runAllManagedModulesForAllRequests="true" >

<add name="RadCompression" type="Telerik.Web.UI.RadCompression"/>

</modules>

<handlers>

<remove name="asset" />

<add name="asset" preCondition="integratedMode" verb="GET,HEAD" path="asset.axd" type="Telerik.Web.Mvc.WebAssetHttpHandler, Telerik.Web.Mvc" />

<add name="Ajax" verb="POST,GET" path="ajax/*.ashx" type="Ajax.PageHandlerFactory, Ajax" />

</handlers>

</system.webServer>

and

<httpModules>

<add name="RadCompression" type="Telerik.Web.UI.RadCompression" />

</httpModules>

I also have a Silverlight app that queryies the webservice. I expect my data to be compressed in some way, but after looking at fiddler, I don't see any compression at all.

What am I doing wrong?

Thanks,
Joe

[UPDATE]
I forgot to mention that I'm using the absolute latest Telerik ASP.NET AJAX control, and the latest, minus the controls they released on April 19 for silverlight

RadScheduler Performance Issue

I have an application that is opening a RadWindow which contains two combo boxes that are used to filter a RadScheduler. The application is a dental scheduler. The user selects a location and a doctor and the calendar refreshes to show all appointments for the month. There is also a RadGrid to show client previous appointments for a selected item.

The app works great for the most part. The problem I'm having is that I had to import data from an old Access app that didn't have all of the fields available in the new app. So I had to default the doctor, and all imported records were set to one person. Moving forward the dental staff can reset these as they have time. I don't know who the customer saw, only the dental staff would.

Problem is that if you select this one doctor, the scheduler REALLY dogs. Any navigation of months is extremely slow. I have the database indexed but the loading of the RadScheduler is slow. For the new entries that are split apart there is no issue.

Is there some sort of trick like on-demand loading, server caching, or something else I could do to speed this up in the interim? I don't think it's going to be an issue when the staff gets all of the appointments reset to the proper doctors. At that time there won't be a single doctor with thousands of appointments. What I see data-wise is that the scheduler chokes at over 30 appointments in a month.

Thanks!

Group Panel Issue

I have a RadGrid on my form that has Grouping Enabled. When I run this in IE 8 the Grid shows up fine, the Group Panel is at the top and I can Group.

When I go to FireFox the group Panel is off to the left of the columns. It looks like its being treated like another column. My code is below.
