Datagridview - necessity not to update the data source

[Guest]

Hi,
I have a datagridview to which I bind a collection, something like
TranslateGrid.DataSource = translationCollection.
The grid consists of textboxes.
But when I update the textboxes in the grid, the data in the
collection(translationCollection) is also getting updated which I don't need.
How can this be prevented?

The whole idea of databinding is to enable the transfer of data from your
model to the user interface.

If the grid is bound to the data you will edit any data automatically.

If you just want to display data without editing you can bind to a list of
objects that wrap your real objects but that have rea-only properties. You
can mark your own properties as read-only using the ReadOnlyAttribute or you
can unbind the data and use a virtual grid mode to display the data without
the underlying databound connection.

Hi Vinay,

What should be updated if you update the textbox, if not the underlying datasource?
Do prevent an update of a property of the translationCollection objects,you could create a getter only property, or add a display property thatmay contain a setter which does nothing, or updates something else.
