[Solved] Help debugging error

[Søren Hartig]

Hi guys,

I wonder when you have an error like this, what is the best way to track it down to the exact RadComboBox in the Grid?

Message:

name is neither a DataColumn nor a DataRelation for table pv_contracts.

Trace:

Hi Bruno,

If you have any grid drop down columns or combo boxes inside templates you can try to comment/remove them temporary.

Hi Vlad,

That would be the normal situation, but this is all dynamic, so, there is one page without any control and all controls are created from an XML file (design file).

Thing is that I can't figure it out what control ID is this, if I could see the ID I would point exactly to the correct one in the design and see what's wrong with it...

I was thinking , when I posted this that you probably had a way to invoke the id, somewhere, somehow :)

Hello Bruno,

The error indicates that you do not have a column called 'name' in the table 'pv_contracts' which is referenced due to some reason to bind the data in your grid.

What you can do is remove the built-in GridDropDownColumns in your grid instance (from the XML source file) to see whether this eliminates the exception and then start adding them one by one to detect which causes the error and after that investigate why this happens.
