Hi to everyone, I have the following sample below and after I put the save button i got the following error message: "LinqDataSource 'LinqDataSource1' does not support the Update operation unless EnableUpdate is true. " For me it seems that everything is ok, can someone help me ? Regards Thorsten

There is an actual "EnableUpdate" property that must be set to True before updating will work.

I set this update property to true but nothing happens. Here is my code: "

Keine Datensätze vorhanden. "

Hi how can I add my sample code. If I paste it into this post you can not see it because it is asp.net code. Regards Thorsten

Add your code to the post using the "Source Code" toolbar button which is the last button on the toolbar.

If I push reply to your message I have not got soemthing with post source code ?

Just below the "Message" header is the command toolbar. At the very right should be your "Source Code" button.

I'am very sorry but I have not got any source code button. I have Compose, Options, Related, Preview nothing else

If you don't have a toolbar below the Message header within the Compose tab, then I'm not sure what to tell you.

I solve the problem. Now I have the toolbar.

Here is my sample code:

Glad you got that working, but I hate to say that I've never seen or used the DynamicGridView control. If I were you, I'd post a new thread to the group to see if someone else may have.

Good luck!

Note that this post is asking about the Dynamic Data CTP - forums are here: http://forums.asp.net/t/1192096.aspx.

You should try out the latest release of Dynamic Data as some of this functionality has changed.
