Custom controls in 2008

Question

Using custom controls in VS 2008 shows frequent errors like object reference not set to an instance of an object and 'could not be set on prperty'.

I have to use the existing custom control created by other team. But when implemeting those controls in my page show the error as i have mentioned

for an example

Section panel has the property collapsed = true or false but when i use this it shows me an error CustomControls:SectionPanel could not be set on property collapsed. Like this, for all the controls am getting error but not every time.

Answer 1

It sounds like you need to talk to the team that developed the controls. Perhaps they didn't do a very good job developing them, or there is a specific way in which you need to install the controls.
