Proplem populating a DataRow with changed rows after an edit/update

[Anthony]

When I debug my code for editing/updating rows in the RadGrid, the following line of code:

DataRow[] changedRows = usersTable.Select(editedItem.OwnerTableView.DataKeyValues[editedItem.ItemIndex]["GUID"].ToString());

... throws the following error:

"from Syntax error: Missing operand after 'c93' operator."

The code is taken and adapted (very slightly) from the Update_Command() method in the code example here.

What does the error mean?

Also, can you suggest any other resources on the InPlace editing for RadGrid as I don't find the Telerik examples very clear (minimal code comments and description). I find the ordering of examples quite disjointed at times. From an ASP.NET point of view, I'm a beginner, so it could just be my inexperience!

The reason for this error is because I was attempting to pass a GUID into the DataTable.Select() method. The Select() method was falling over when it came across hyphen characters in the GUID.

Thanks for your response anyway.

Hello Anthony,

I am afraid that the provided information is not enough for us to determine what exactly the problem is and the reason for it.You can send me the whole page code (aspx, cs) for further check so I try finding what went wrong there.

All the best,

As per my post before your most recent reply, the error was being thrown because the DataTable.Select() method did not like the hyphen characters in the string I was passing into it. It isn't a problem with the RadGrid.
