[Solved] Selfreferencing hierarchy error/bug

Hello there,

I followed your selfreferencing hierarchy sample and ran into the following error:

System.Data.SyntaxErrorException: Syntax error in Lookup expression: Expecting keyword 'Parent' followed by a single column argument with possible relation qualifier: Parent[(<relation_name>)].<column_name>.

I set the EnableLinqExpressions to false, but that didn't help. Tried using different datasource implementation, but no help either.

Then I tried changing my Columnname in my objectdatasource (and corresponding MSSQL server table column) to MyParent instead of Parent. And then the problem went away.

So probably the grid is not accepting a parent - child relation defined with a column named Parent referencing the Keycolumn.

Using 2009, 3, 1314, 35 build.

Http Compression Module w/ Telerik Controls

I am wondering if Telerik (or someone else) has any recommendations for Http Compression modules that work with ASP.NET AJAX & Telerik controls. I've tried a few (Blowery, mbCompression), and usually ran into issues when it came to AJAX usage. Unfortunately, I am running IIS6 for the foreseeable future so using IIS7's compression is not an option. Any suggestions for a module are greatly appreciated.

Thanks!

"Tree view Problem "

HI,

I have used telerik treeview control.
Tree view is dynamically created, which depend on database values.
I have set multiselect property to "false".
Its working fine with single Tree view but when I display more than one instance of tree view multiple selection is possible which is confusing to the user.I want only single node to be clicked by the user.
I have attached image showing multiple selection.
I want one node to be selected at a time.
How can I achieve this ? Please suggest me.

Thanks.

Upgrade Wizard Not Listing Newly Downloaded Version

I'm not sure if this is a bug as I didn't have time to properly investigate. I used the upgrade wizard to download the latest version (q1 2010). It found the new version, downloaded, and extracted. The problem was Q1 2010 wasn't listed as one of the version choices to upgrade to. If you don't want to download it again, the files are downloaded and extracted to %appdata%\Telerik\Updates. I just hit browse in the select version screen. The upgrade wizard has always worked better for me (seems to manage the vs toolbox better) so I was glad to get this working. Hope this helps others.
