Can't edit feature class, Arcgis Engine 10

I found that if the layer/data wasn't versioned, we can not modify it and it won't appear at the target layer combo box.


What I did was register the dedicated layer and that's it. The feature class then appear at the toolbar and now I can edit the layer :)


In the process of register the layer, I also got a problem which the layer associated with locks on my machine.

Failed to register as versioned. 

After google and search for the solution, I just restart the SDE services.
The process of register the layer into version went well after that.


:)


Happy! Now i can go back, it's already late.
Work, see you tomorrow :)
