I found out about this the hard way, so thought I would share my experience.  Using the RadTreeView version 2009 Q1, I was adding a node to a tree and setting its value on the client-side before committing my changes to the server, like so:


on the client, and


on the server.  The last line, string nodeID = node.Value, was causing the following error to occur:

System.InvalidCastException: Unable to cast object of type 'System.Int32' to type 'System.String'.

After some investigation, I realised that I needed to cast the node ID to a string in the client-side code in order to avoid an error on the server!  This proved to be successful:


Maybe in the next release the client-side set_value() function could automatically cast its argument to a string?  Having said that, I don't remember seeing this error in 2008 Q3, so maybe there's a bug somewhere.

Hi!
I have a datetime datetimecolumn where I have enabled filtering (AllowFiltering = true). I don't want users to see the filters (ShowFilterIcon = false) so I have disabled this feature. I have also bounded to the ItemCommand event.

The datepicker is opening perfect when i want to filter for a specific date. The event is also raised on the server side.
The problem is if I clear the textfield with the keyboard a postback is made but no call to the event ItemCommand is raised. Is there something I have missed?

Best Regards Erik

Hi Everyone,

I am wondering if it's possible to have childgrids at he same level but with different columns kind of:



Column1, Column2, Column3 and Column4 are the same in each childgrid

   In fact each childgrid would be independant from the others in terms number of columns. Some column would show and other wouldn't depending of the data in the database (if N/A the column doen't show for that childgrid)

I am changing the datatable  for each childgrid (because they are different) DetailTableDataBind but the columns generated doesn't maps the datatable.

Right now every childgrid is following the pattern of the first chidlgrid leaving blank field even if the column is not in the datatable.




I hope i am clear enough

Thank you

Regis

Inside the OnExcelExportCellFormatting instead of having to assign the "UniqueName":

if (e.FormattedColumn.UniqueName == "Freight")
{
  e.Cell.Style["mso-number-format"] = @"0";
}

Could we not Style all the datatype fields of date be automatically formated to the date format that you want?

I am using the 2009 Q1 build of the editor control within a DotNetNuke 4.9.3 website.

I added the AJAX Spellchecker button to the editor's toolbar but when I run the site and click on that button, the Finish spellcheking and "Cancel" buttons remain grayed out and I get a javascript error that says:

Cannot deserialize. The data does not correspond to valid JSON

I've seen other posts on this, and have tried some workarounds, but none correct this issue.

How do I get the spellcheck functionality to work?

Thx,

Jason

We are having serious problems exporting data to CSV and Excel using the built in functions.  We may be wishing to export upto 100000 rows of data with file sizes between 10 and 100 MBytes.   We keep getting System.OutOfMemory Exceptions.   We are aware that data exports of this size may take some time to download, but our clients need them.  

Have you any plans to improve your data export functionality in the near future or should we investigate alternate routes?  It is clear from reviewing comments such as these:

http://www.telerik.com/community/forums/aspnet-ajax/grid/problem-to-export-to-excel.aspx

http://www.telerik.com/community/forums/aspnet-ajax/grid/system-outofmemoryexception.aspx

that there is an acknoweged problem; could you also give some guidance as to what a reasonable file size for generating from your export functions would be?

Hey

I'm adding a textbox and a button codebehind using a <asp:Table>. I'm using RadAjaxPanel, but when i push the button i don't get a ajax postback. If i put the button in the aspx file, everything works fine. How can i resolv this?

hello ... when i use the editor in default tools mode, it give me the word / character count ... cool. however when i look at the two full sets of menus from telerik, I don't see that in the xml file anywhere... so how to do it? I found the article on custom word/char counts.. 
http://www.telerik.com/support/kb/aspnet-ajax/editor/implementing-custom-word-character-counter.aspx but when you have more than one editor on the page, it starts to get messy to deal with.
How would I implement a counter that will deal with multiple editors on one page? It would be nice if we could embed it into the editor box like when we use default.

thanks
