81⟩ What is PreProcessor in .NET and type, where it use?

The pre-processing directives provide the ability to conditionally skip sections of source files, to report error and warning conditions, and to delineate distinct regions of source code. The term "pre-processing directives" is used only for consistency with the C and C++ programming languages. In C#, there is no separate pre-processing step; pre-processing directives are processed as part of the lexical analysis phase.

A preprocessor directive must be the only instruction on a line. Preprocessing directives are lines in your program that start with `#'. Whitespace is allowed before and after the `#'. The `#' is followed by an identifier that is the directive name. For example, `#define' is the directive

Types are:

#if, #else, #elif, #endif, #define, #undef, #warning, #error, #line, #region, #endregion

They are used for:

Conditional compilation

Line control

Error and Warning reporting

86⟩ In A Page I have gridview with Options of select and delete using hyperlink when i am selecting any one of then it has to open another page how can it?

You can have template column for select and delete instead of the databound column. In which you can mention the destination page where you need to navigate.

Using RowDataBound event, you can add attribute to the select and delete hyperlink like:

e.Row.Cells(CellPosition).Controls(0).Attributes.Add("OnClick","return fnJavascriptFunction()")

e.Row.Cells(CellPosition).Controls(0).Attributes.Add("OnClick","return fnJavascriptFunction('"& If any argument &"')").
