I am using a hierarchical radgrid and have performance issues.

The grid is 3 levels deep
level 1: 11 columns
level 2: 12 columns.  Nested into a detailTables
level 3 13 columns.  Nested into a panel inside NestedViewTemplate

Because of the performance issue, I did the following:
- Set the HierarchyLoadMode is set to ServerOnDemand.
- Bind server side and if the pageSize is 25, I only take 25 items from the database (I manage the paging myself).
- Removed filters and sorting from level 2 and 3

Each level has custom paging

During my tests, I realized that when binding the 1st level, the header and footer of each child grids were correctly loaded on demand.
However, when expanding the second level,  the header and footer of all 3rd level child grids were initialized at the same time.

The 3 level is inside an invisible panel. 
The panel is set to visible only when it is expanded.
The data of the third level is loaded on demand as expected, but the header and footer is initialized as soon as its parent is expanded.

Is there a way to prevent that ?  I tought the invisible panel was enough to prevent the grid initialization.
Do you have any other suggestion to resolve the performance issue ?
Note: the problem is not visible on IE9, but is always present on IE7.

Thanks

Having issues with IE9 clipping or mis-positioning elements in your constrol set. I have attached an example. Everything looks ok in Chrome.

Hallo,

let's say I have 1000 rows. If I group by a specific column I'm getting 10 groups each with 100 rows. Paging is enabled with 10 rows per page.

If I group I want to see all the 10 groups on a single page. Only when I expand a group more when one page is used.

Is there any possibility to get this behavior?

As paging, in conjunction with grouping is implemented, it is not usable today.

Please let me know how to group the Radmenu items by headers. I binding the menu with data from SiteMapDataSource
I need to group the items similar to the menu that I see on telerik site

Say in the URL : http://www.telerik.com/community/forums/new-thread.aspx?forumId=250 under the Main Menu item "Products", items of the menu are grouped under a header

 "WEB UI CONTROLS & COMPONENTS",
 "DESKTOP UI CONTROLS & COMPONENTS"
 "DATA TOOLS"

Thanks

I have a strange thing when entering values in a RadNumericTextbox with and without decimals. I was able to reproduce the behavior with this simple form:
 
To reproduce do the following:
1) In the first textbox enter 2.2 (i have Swedish culture set so comma (,) is my my decimal separator).
2) Using the mouse, click the second textbox.
3) My first textbox now shows 2.20 (and thats what i expected).
4) Click the first textbox again (value selected).
5) Just enter a 2 on the keyboard
6) Click on the second textbox

My first textbox still shows 2.20 but I was expecting 2.00!

This surely cannot be an expected behavior, is there something I am missing?  A property that must be set?

The funny thing is that I can cure this behavior by pressing [ENTER] while in the first textbox. After that all works as expected.

Using v.2012.2.607.40 components.

Anyone got an idea what this is all about?

Hi,

I am using the timeline view to schedule jobs to our users. I need to be able to show the full subject name which can be rather long. I have setup some custom CSS  classes that get applied to appointments with long names. (This can be seen in LongApName.png)

These appointments look fine, until you put two on the same day. Then they can overlap.

In thisTimeline Demo the "Margaret Morrison Main Room" Row has a height of 75px, Where is this set? I believe this could be a workaround to my real problem.

Cheers, Grant Cannan

 RadEditor1.Content = ReadFile(Server.MapPath("~/"+Root()+"/example.htm");
                    string mod = Root().Replace(" ", "%20");
                    RadEditor1.Content.Replace("href='"+mod,"href='"+NewRoot);
                     using (StreamWriter externalFile = new StreamWriter(Path.Combine(Server.MapPath("~/"+NewRoot), "Newexample.htm"), false, Encoding.UTF8))//Open file for writing and write content
                    {
                        externalFile.Write(RadEditor1.Content);
                    }
 protected string ReadFile(string path)
    {
        if (!System.IO.File.Exists(path))
        { return string.Empty; }//fin if file exists
        using (System.IO.StreamReader sr = new System.IO.StreamReader(path, Encoding.GetEncoding("macintosh")))
        { return sr.ReadToEnd(); }
    }
but I think that Replace() no work with html, please help me

Hi,

I was using the file explorer to load files from a shared path as shown in the article http://www.telerik.com/support/kb/aspnet-ajax/fileexplorer/physical-paths-and-different-content-types.aspx.
I have a couple of file explorer controls on my page. For one of them the shared path is formed dynamically. When I run the project I am not able to see files in that control. Is it because I don't have a mapping specified for that particular path. How can i resolve this?
