Questions on UI for ASP.NET AJAX Forum

I used an example I found in these forums to show the # of files in a directory beside the name of the directory. The example seems to work fine but once I tried to change it around to suit my exact needs, I found some issues.

I wanted the following changes
1. All directories to show # of files within it including subdirectories (no problem, easily done)
2. Setting the paths in the code behind rather than within the html
3. Any change to the files (i.e. upload new file, delete file, move file) will automatically refresh the treeview

Here are the problems I experienced:
- if you set the path in the code behind, the refresh button will not update the # of files in the treeview (but will work if path are set within the html code)
- I tried to use RadFileExplorer1.TreeView.Nodes.Clear(); in the page_load to force a refresh of the treeview (which works) but this had an adverse side effect. After a file delete or file move, the changed file still appears in the grid as if the file wasn't deleted or moved until I pressed the refresh button.

Help?

How to initiate a row edit from code behind?

I am building a row button that'll make a duplicate of the row the user clicked. I want it to then let the user edit the row. In my particular case I am using the built in popup form to edit the row.

So I have a GridButtonColumn, I catch it in the OnItemCommand event - but how do I initiate the edit on the new row? Or, bring up the New Row form, loaded with the data from the row I'm copying?

RadUpload invisible controls

I have a RadWindow acting as a wizard in an application, and one of the pages contains a RadUpload. This has worked fine on both my development and production environment. Recently I upgraded the project from a 2009 version (I forget which one) of Telerik RadControls for ASP.NET Ajax to Q1 2011. This tests fine in development. However in the production environment, after modifying the Web Application to run ASP.NET 4 (It was 2), the RadUpload items began acting strangely. I have these in a few places and usually, they include the input area and the Select button. I am finding that they are invisible on the production server, where they are visible on the development server. I am running IIS 6 on production and IIS 7 on development. I also added a dummy RadUpload with all controls visible, and when I do this all I see are Add and Delete buttons. I also notice that this only occurs in the RadWindow page, where some other pages that contain RadUpload controls behave normally.

Is there something I need to do when I upgrade the production to a new version of Telerik RadControls for ASP.NET Ajax? I copied in the new Telerik.Web.UI.dll, Telerik.Web.UI.Dll.Refresh and Telerik.Web.UI.XML files. Also I sync'ed up the web.config files such that the production and development versions only differ in the App Settings sections.

Thanks, Steve

set current page index and row focus in javascript

var grid = $find(gridID);

var masterTable = grid.get_masterTableView();

var dataItems = masterTable.get_dataItems();

var row = dataItems[itemIndex].get_element();

masterTable.set_currentPageIndex(page);

row.focus();

What I am trying to do is: i have a textbox with a number and when I mouse over on it, I pass the number to the parameters of "page" and "itemIndex", I want the grid show on that page and also focus on the row of that number. I can see the grid is refreshed on mouseover but the current page stay unchanged and the row focus doesn't work, if I change to masterTable.selectItem(row), it works ONLY when the current page is set to the one contains that row. Did I miss anything?

Thank you!

Updating the Page Title whilst using a RadAjaxPanel

I have a page which includes both a master and details panel scenario and i want to update the page title when i hit the detail sub routine.

The code to this is working but as I am using RadAjaxPanel the head seciton of the page is not being updated. I have tried EnablePageHeadUpdate="true" but does not make difference, am i missing something?

Of course as soon as I remove the RadAjaxPanel everything works just fine but dont want to lose my slick looking telerik stuff!

Cheers,

RadEditor not rendering

I have a RadEditor placed on a content page. When I run the web application locally (ASP.NET 3.5), the RadEditor shows up fine. When I deploy the web application to our production server, the editor doesn't show up, instead I get a series of bullet points that when hovered over show a tooltip of a toolbar.

I don't have the code with me right now, but can anyone suggest what I should check when I get back into work on Monday? Any pointers would be appreciated! I don't understand how it works fine locally (when I hit F5 in visual studio 2010), but when I deploy to the server it doesnt work. I can confirm that there are other applications on the server I am deploying to where the RadEditor works fine, just not in my web application project. Do I need to check any specific web.config settings?

Thanks
