Body
It may not be the brightest idea, but you can query the database for the current state, and the compare with what you have got from the web page during a postback button click, or something like that. Or you can go with Brians answer. It is possible to persist a list of objects into the Viewstate and access it in a consequent postback. The only thing is that the object you are trying to persist must be defined as serializable. Update: The ViewState approach I feel this may be suitable for your need, and it requires a bit of linq. You'd need to create a class as follows: <pre><code>[Serializable()] public class OptionState { //the id of the item int ID {get;set;} //state of the checkbox bool Checked {get;set;} } </code></pre> Note the Serializable attribute. This is required for the instance to persist to the viewstate. Add the list of options to the viewstate: <pre><code>var lstOptions = (from x in <your_option_store> select new OptionState{ID = x.ID, Checked = x.Checked}).ToList(); ViewState.Add("options", lstOptions); </code></pre> Here is a bit of code that should go into your button click: <pre><code>foreach(GridViewRow row in gvOptions.Rows) { //not writing the bit of code //which gets the ID and the //state of checkbox of //the gridview row being processed OptionState currentState = GetOptionStateObjectFromRow(row); List<OptionState> lstStates = (List<OptionState>) ViewState["options"]; OptionState originalState = lstStates.FirstOrDefault(x => x.ID == currentState.ID); if(currentState.Checked != originalState.Checked) { //the appropriate db call needs to be done here. } } </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
