Solution 1

It means that in your View you are trying to bind to a value called "AspdotNet", but this value does not exist in the data you are binding to.
Ensure that your bindings are all correct and this error will go the way of the dodo. (The extinct bird for those who don't get the reference)

Update:
I'll try to be more clear:
1) You have a databound column in your UI.
2) That databound column is trying to bind to a column in your data called "AspdotNet".
3) "AspdotNet" does not exist in the data you are binding to.
4) That is why the error is being thrown.

Update 2:
I'm pretty sure that this #Eval(" ASP dot Net Marks";) isn't going to work. I'm pretty sure that your column name coming from the database is not this. Check your datasource column names and make sure that this one matches exactly the column name you are trying to show.

Could you use the "Improve Question" widget above and update your original question with the code. I'm thinking the comment method used has cut off some of the code because there are no databound controls in the code you pasted. If you put it in the question, I'll remove the code that isn't relevant and then I can help a little more.

I'm trying to help you. Please follow the instructions I'm giving you.
At the top of this page, on the right hand side you will find a green link "Improve Question". Please use that to paste your code into your question. Putting the code into the comments here isn't useful because there is too much to look at that way.
