Validation controls check user input in SelectionList and TextBox controls. Validation occurs when the form is posted to the server. The validation controls test the user’s input and, if the input fails any of the validation tests, ASP.NET sends the page back to the client device.

<identity impersonate=”false”/> It means that ASP.NET will not perform any authentication and runs with its own privileges. By default ASP.NET runs as [...]
Server controls like Datagrid, DataList, Repeater can have other child controls inside them. Example DataGrid can have combo box inside datagrid. These child control do not raise there events by themselves, rather they pass the event to the container parent (which can be a datagrid, datalist, repeater), which passed to the page as “ItemCommand” event. [...]
ASP.NET does not run by itself, it runs inside the process of IIS(Internet Information Service). So there are two authentication layers which exist in ASP.NET system. First authentication happens at the IIS level and then at the ASP.NET level depending on the WEB.CONFIG file.
Below is how the whole process works:-
<1> IIS first checks to make [...]
