I am looking to sort a column on my gridview by simply clicking on the column rather than clicking on the column header. In the design I have been given, the column header will not be shown, and I need to be able to give the user to sort this column, by simply just clicking any where on the column.
I have a gridview which is binded to a Sqldatasource. I would like to replace a column data field value to 'Not Applicable' if that column has got a value of 2 in database.

I have a boundcolumn that outputs string numbers. I have another column of checkboxes next to it. I need to have it so that when a user checks off a check box the value stored in the string column to the left is then plugged into a function on the server. How can I acheive this?Here is my code:
I'm currently working on a small project and therefore created a gridview, including one bit column which has been linked with a checkbox in both the itemtemplate as the edititemtemplate (autopostback = true).Databinding for these two checkboxes has been linked (two-way) to the bit column.Now I want to display the gridview to end-users. They should be able to just click on the checkbox so they value in the database column gets changed as well (as I want to run update queries behind it), but not passing via the command column 'EDIT'.=> problem I'm having now is that the bit column in the database doesn't get updated.

Situation: SQL database, Linq to SQL class a ASP.NET page with a LinqDataSource and a gridview. The table has a ID field, a date field and a Serialnr field. In my Grid I like to Page on the datefield but to sort on the serialnr field ( or a selectable other field). Is that possible? Standard the paging is always done on the sort field and when you select a different sort field the page jumps back to the first page., and paging is then done over that sorted column.
