Hi,

I would like to like have a grid where user can modify data (add, remove and edit) and finally Update changes to the database.

So, clicking delete would not delete data from the database, instead it would remove row from the grid only. Under the grid would be a Save button. Any ideas how to accomplish this kind functionality? Also another question is that how can I access all rows instead of one?

Hi Uma,

I have used normal form collection to fake inline editing. I use hidden field to identify row and visual data is normally input type of text.

When user adds a empty row:
- form will be posted and each row is in the FormCollection. For example formCollection['id'][2], formCollection['name'][2] would represent row 3 id and name.
- then I'll set previous data + a new empty row to the ViewModel

When used removes a row
- I'll get current situation as describes in the Add
- I give an id of the clicked row to the Action method
- Then I remove that row and again I set previous data - deleted row to the ViewModel

When user edits a row
- I don't save anything in this situation. User-interface will hold the information. Only when new row, delete row or grid save happens then we need to store it (save uses database, others uses in-memory editing)

When user saves complete grid
- I'll get current situation as describes in the Add
- Convert form collection to class and save the information

This is just a rough example how I solved the problem. Even if the example looks "dirty", you can do this quite nicely using good programming practices. :)
