First off, im using a checkbox to highlight a true or false value from a dataset which I want to be able to change it. Unfortunately databinding the DataTable to the GridView checkboxes doesnt work (as you probably know) as it requires it to be in “edit” mode.

The way I’ve gotten round this is having the checkbox reading the data table value seperately rather than being databound and locked:

Checked='<%# Convert.ToBoolean(Eval("myValue")) %>'

So that solves checkbox values from DataTable -> GridView, now I need to do the opposite having the changed checkbox values go from GridView -> DataTable as it is not ready to submit it to my data source (SQL) just yet.

I figure I need to run a loop through the GridView rows, thats a give’un, what I can’t figure out is how to replace/update just a single value in a row of a DataTable , only the ability to add or remove an entire row by the looks of things (something I don’t want to do).

So can anyone offer a workaround?
Or is there a way to have a databound but always editable checkbox in a gridview?

    I’ve addressed the problem by starting from this article by Matt Dotson and the associated code:

    Basically its possible to make all the rows editable by default – in your case you’d want the majority of the columns to be read only. I think my first attempts just used the code pretty much as give, but my more recent attempts have been done with my own code based on the above.
