I have developed an ASP.NET datagrid control, the datagrid control has multiple editable columns with on column containing a dropdown list.
I use the Item Command Edit, Update and Cancel buttins to make the grid editable, then save the changes to the dataset using the Update button. Finally I update the database with this updated dataset with a button placed outside the grid.
Now I want to implement the same datagrid but this time using a checkbox.
I should be able to select multiple rows at one time, edit the values in them, then finally update the database with the updated values in the dataset.
Please advice on moving forward with this one.

Thanks!

I am not sure this can be done. You can have a grid where all the rows are editable at the same time

All the three parts of the article provide excellent background on how to update the dataset for multiple rows.

In my case what I did is for each datagrid Item I checked if the CheckBox is checked or not,

I then changed the values in the textbox and dropdown to the desired values and then iterated throug these values to save the changes to the session dataset. Once the dataset was updated I have the option of updating the dataset using the dataadaptors update command.

Thanks the link was really helpful :)

Glad to help
